Alicyclobacillus acidoterrestris causes spoilage in fruit juices. This research investigated the effects of organic acids on the growth of two strains of A. acidoterrestris at different pH values and temperatures over 2, 7 and 14 days. The results show different impacts of weak acids on A. acidoterrestris’s growth and survival. Ascorbic and malic acids have the highest antimicrobial activity; also, pH played a crucial role. Moreover, the results suggest a possible activity of acids on outgrowing spores rather than on spores. Understanding the organic acids interactions with A. acidoterrestris is crucial for implementing strategies to ensure quality and reduce spoilage incidents. Full article

This study developed a predictive model for Escherichia coli survival in Amlou, a Moroccan almond–honey–argan oil spread, focusing on argan oil, sugar, and peptone concentrations. Based on the Doehlert matrix design, relationships were established between these ingredients and the death rate (DR) and survival period (SP). Sugar affected the DR, while argan oil and peptone influenced the SP. The DR model demonstrated an RMSE of 0.0095 and SEP of 22.22%, confirming its accuracy. This work offers valuable insights for food producers about E. coli’s behavior in Amlou-like foods. Full article

Monascus purpureus is a red pigment-producing fungus. In the present study, the effect of fish hydrolysate and sodium chloride on the colour of quinoa flour fermented with M. purpureus was analysed. The colour of each sample was evaluated in CIELAB space (L*, a*, b*), in addition to the C:N ratio. The minimum fermentation time was eight days and the values of L* (44.66 ± 0.532), a* (20.27 ± 0.323), b*(17.89 ± 1.342) and a C:N ratio of 11.05 ± 0.240 were obtained. Therefore, there is an effect of supplementation on increasing the red colour of the meal. This work opened up the possibility that red quinoa flour could be used as a raw material in the production of other food products. Full article

Food waste is seen as a societal, economic, and environmental challenge, threatening food security and causing natural resource overconsumption and nutrition loss. There is inequality in the distribution of food resources around the world and many countries have been suffering from hunger while others have excess food that goes to waste. Indeed, the Food and Agriculture Organization estimates that we entered 2022 with 828 million hungry people, the majority of whom are women and children suffering from malnutrition, wasting, and stunting. Moreover, the UNEP Food Waste Index 2021 indicated that nearly 931 million tons of food waste were produced in 2019, of which 61% originated from households, 26% from restaurants and food service, and 13% from retail. This, of course, hinders the achievement of the zero hunger goal by 2030. In this context, we analyze the main challenges and opportunities of using food waste produced by tourism activities using an S (Strengths), W (Weaknesses), O (Opportunities), and T (threats) analysis. The analysis shows that the challenges could be a source of important opportunities. We recommend enhancing the awareness of restaurants and food business owners about the impacts of increasing food waste on the economy and environment, and about the importance of waste selection and adopting the circular bioeconomy concept for the sustainable development of their businesses.

Chickpea (Cicer arietinum L.) is a significant pulse crop in Australia, with an industry value of over AUD 1.3 billion. However, there are few studies investigating the levels of health-benefiting constituents in desi chickpeas and the impacts of variety, growing location, and season on these constituents. This study aimed to study the levels of health-benefiting constituents in desi chickpeas, including 97 samples of Australian desi chickpeas, comprising 18 varieties, grown in a range of field trials across four Victorian locations and three growing seasons. Various physical characteristics and phytochemical compositions were determined in the samples, including 100-seed weight, colour, moisture content, total phenolic content (TPC), ferric-reducing antioxidant potential (FRAP), cupric-reducing antioxidant potential (CUPRAC), and total monomeric anthocyanin content (TMAC). The screening results showed a significant difference in TPC, TMAC, and FRAP among different desi varieties, suggesting there may be variation in their potential health benefits. Furthermore, the growing location and growing season significantly impacted all analytes. Correlation analysis revealed a number of significant correlations, including a moderate positive correlation between the b* colour and the antioxidant capacity and total phenolic content. This work provides the first detailed insight into the range of phenolic and antioxidant contents found in Australian desi chickpeas and the impact that genotype, location, and season can have.

Antioxidants are known to play a crucial role in maintaining cellular health by neutralizing harmful free radicals. Among various dietary sources of antioxidants, wheat-based products, particularly flours, have gained significant attention due to their potential health benefits. Durum wheat, a widely cultivated species, serves as a primary ingredient in numerous food products. However, limited research has been conducted to assess the antioxidant activity of flours obtained from durum wheat varieties. In this study, we aimed to comparatively evaluate the antioxidant and antiplatelet potential of flours from 22 selected durum wheat varieties cultivated in Greece. We focused on three major parameters for antioxidant activity measurement: total phenolic content, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and ferric-reducing antioxidant power (FRAP). The total phenolic content was determined using the Folin–Ciocalteu method, while DPPH and FRAP assays were employed to assess the ability of flours to scavenge free radicals and reduce ferric ions, respectively. The antiplatelet activity was evaluated using a platelet-activating factor inhibition assay (PAF) in platelet-rich plasma. Analysis of the data revealed notable differences in the total phenolics and antioxidant and antiplatelet activities among the tested samples. The total phenolic content ranged from 624.0 ± 3.5 to 950.0 ± 5.3 μg of gallic acid equivalent/g flour with the variety Zeta E having the highest content. The antioxidant activities based on the DPPH and FRAP assays ranged from 0.56 ± 0.02 to 2.26 ± 0.08 and 1.93 ± 0.02 to 3.65 ± 0.03 μmol of Trolox equivalent/g flour, respectively, with the varieties Marco Aurelio and Zeta E exerting the highest antioxidant activities in the DPPH and FRAP tests, respectively. In addition, the IC50 values for the antiplatelet activity ranged from 0.72 ± 0.21 to 3.06 ± 0.17 in mg of flour, with the variety of Zoi exhibiting the highest antiplatelet activity. Overall, this comparative evaluation highlights the differences in the antioxidant and antiplatelet activities among flours obtained from 22 different durum wheat varieties cultivated in Greece. The results from this study aid in the selection of wheat varieties with superior antioxidant and antiplatelet capacities for use in bakery food formulation and dietary recommendations. Full article

The increasing demand for natural bioactive ingredients extracted from Aromatic and Medicinal Plants (AMPs) has produced disposal problems associated with residual solid waste. One of the main sectors interested in the exploitation of AMPs is the Essential Oils (EOs) industry. Despite EOs being the main commodity in the EOs industry, they only represent a small part of AMPs, generally less than 5% (w/w). This results in the production of a remarkable quantity of biomass that has no apparent commercial value and is therefore underestimated and underutilized by the EOs industry. Among AMPs, Rosmarinus officinalis L., commonly known as rosemary and belonging to the Lamiaceae family, is an aromatic plant endemic to the coastal area of the Mediterranean region but spread worldwide. Rosemary can be cultivated or grow wild as an ornamental evergreen shrub. Their leaves are usually used fresh or dried to flavor foods, mostly in traditional Mediterranean gastronomy, and recently, rosemary extracts were approved for use as food additives in Europe. The antioxidant activity of rosemary leaves has been acknowledged and is ascribed to EOs and polyphenolic compounds. To the best of our knowledge, the optimization of polyphenol recovery from rosemary residues after EO extraction has not yet been investigated. Hence, for the present study, EO extraction from rosemary leaves was performed using the hydro-distillation method, and the antioxidant (EC₅₀) and sun-protective (measured in SPF) activities were evaluated. The polyphenolic fraction was extracted from the rosemary residue under specific experimental variables. In particular, tests were conducted at different extraction times (15 min, 30 min, and 60 min), temperatures (25 °C, 40 °C, 50 °C, 60 °C, and 70 °C), and ethanol concentrations (50%, 60%, 70%, and 80%). In this study, an EO yield of 1.57% was obtained, and the EO had an EC₅₀ value of 240.39 µL/mL and a SPF of 2.55. The maximum amount of polyphenols extracted from the rosemary residue was 24.14 mg GAE/g DW, achieved by using an 80% ethanolic solution at 70 °C for 60 min. This preliminary study reveals how the exploitation and consequential valorization of AMP solid waste may represent new answers for circular economy strategies adopted by European countries.

The outbreak of COVID-19 challenged the sustainability of global agri-food markets. Through this research, the authors have made sincere efforts to recognize and remove/improve the potential factors that contribute towards an inefficient agro-based supply chain. COVID-19 has created much urgency to evaluate the existing supply chain and to propose a valid solution. In this particular research, the involvement of intermediaries is the point of focus. In addition, the profit margins for the farmer are hugely affected due to intermediaries. The current supply chain must be optimized, and this will lead to easier flows between each phase of the supply chain. Surveys were conducted and the farmers’ problems and expected solutions are highlighted in this research. Farmers in the northern states of India experienced more significant disruptions than those in other states because of a decreased availability of foods due to lack of diversity in crops. This research examines the existing supply chain for wheat crops and presents an optimization of the respective supply chain to save farmers more revenue. Through this research, the authors have attempted to observe and explore the problems faced by farmers and consumers due to the inefficient supply chain infrastructure prevalent in India because of the onslaught of COVID-19 and find an efficient solution. Due to the lack of adequate infrastructure, storage facilities, and old food-processing and supply chain technology almost 30–35% of the agricultural produce in India is wasted. A scientific solution to the existing problems is also presented after analyzing the existing supply chain and crop selection of farmers. Full article

Three peanut genotypes were cultivated under ambient and elevated CO₂ conditions. Elevated CO₂ treatment was associated with higher total phenolic content (TPC) values in the shoots and roots of all genotypes. Seeds showed lower levels of TPC compared to the other plant tissue, showing a decline in all three genotypes, and no differences between the CO₂ treatments were observed. The Crude Protein (CP) content in seeds varied significantly among the genotypes, and elevated CO₂ treatment was associated with mild increases (not significant) in CP of 4 and 6% in Holt and Alloway cultivars, respectively. It is worth mentioning that Kairi contained the highest CP content under elevated CO₂ (29%). Full article

Juçara (Euterpe edulis) is a Brazilian Atlantic Forest palm that produces phenolic-rich fruits used for pulp preparation. The pulp refining produces antioxidant and lipid-rich residue. This study applied glycerol as a green solvent for the microwave-assisted extraction of antioxidant compounds from residue. The variables included glycerol concentration (0–100%), microwave time (2–18 min), and temperature (53–187 °C). The total phenolic compounds (TPC) and DPPH^• antioxidant capacity were influenced by glycerol concentration and temperature (p < 0.05). TPC ranged from 1052 to 5329 mg GAE/100g and antioxidant capacity from 29 to 191 µmol Trolox/g. The highest values were at 187 °C, using 50% glycerol for 10 min. All models were significant, with R² above 0.95. Glycerol, as a green solvent in microwave-assisted extraction, improves antioxidant compound recovery from juçara residue, presenting itself as a sustainable approach for adding value to the fruit production chain.

Different statistical approaches were used to analyze the rheological properties of a rice-protein-based product before and after printing. The printing ink was composed of 30% rice protein and 70% water, with the addition of 0.5% xanthan gum. Printing parameters: The layer height (1 and 1.5 mm), printing speed (50 and 35 mm/s), and nozzle diameter (1.2 and 1.7 mm) were evaluated. Rheological properties were determined before and after printing using an oscillatory test from 0.1 to 10 Hz at 1 Pa. The decomposition of the curves into principal components helped us better understand the variations of the rheological properties along the frequency, differentiating the samples before and after printing.

The acorn, a fruit of the Quercus genus, is abundant in Portugal and offers a high nutritional content, including essential minerals and vitamins, unsaturated fatty acids, and bioactive compounds like tannins, phenolic acids, and flavonoids. Despite their antioxidant properties, excessive consumption of tannins can cause health problems due to their effect on protein bioavailability. This study evaluated two extraction techniques, water immersion at room temperature for seven days and thermal hydrolysis via boiling for 30 min, and their effects on acorns’ tannin and mineral content. The results reveal that both extraction methods are viable options for extracting tannins, although they also reduce some important minerals. Full article

There is particular demand for foods with a high antioxidant and phenolic content, which may improve cardiovascular health, reduce inflammation, and slow or prevent the onset of chronic, non-communicable diseases. However, there is a lack of comprehensive databases using consistent analytical protocols to analyze the antioxidant and phenolic content of different food types, particularly in regional areas such as Australia. Over the past four years, our laboratory has analyzed over 1000 food-related samples using several antioxidant capacity assays (ferric reducing antioxidant power—FRAP—and cupric reducing antioxidant capacity—CUPRAC), as well as the total phenolic content (TPC) using the Folin–Ciocalteu method. Here, we provide a summary of these data by different food types to inform researchers, policy planners, nutritionists, and consumers about the typical levels of antioxidants and total phenolics found across a range of Australian foodstuffs, particularly grains. The highest antioxidant and phenolic contents were typically found in native Australian fruits, while grains, nuts, and non-native fruits showed lower antioxidant and phenolic contents. Spices, processed foodstuffs, and non-fruit native Australian foods showed an intermediate content. Furthermore, medicinally used plants showed a much higher phenolic content and antioxidant capacity compared to non-medicinal plants. Finally, we present correlations between the various analytes.

The COVID-19 pandemic has notably influenced eating and lifestyle behaviors, prompting shifts in dietary habits. This study examines lockdown effects on eating patterns and health risks. Lazio, Italy, faced multiple lockdown phases, impacting activities and prompting containment. Studies revealed mixed diet changes during short-term lockdowns, yet long-term impacts remain understudied. The study aims to assess lockdown effects on eating habits and health risks through pre- and post-lockdown questionnaires. Data on eating behaviors, food habits, and taste were gathered pre- and post-lockdowns from a Rome obesity center. Ethical standards were followed, and 1256 individuals participated. All participants were contacted between May and July 2021, with the request to repeat the same online test. In total, 118 participants agreed and were included in this study. A structured questionnaire covered meals, food groups, favorite dishes, and activity. Dietary history and body composition assessments were performed. Analysis demonstrated significant shifts in food consumption patterns. Cereals and raw vegetable intake rose, while legume consumption decreased. Drinking habits changed, but alcohol intake remained steady. The study highlighted changes in diet and lifestyle, including reduced eating out and sleep disturbances. Physical activity remained stable, with more morning sports. The study uncovers COVID-19 lockdowns’ impacts on eating habits and health risks, enriching our understanding of prolonged quarantine effects on food supply and security. Full article

Edible mushrooms have played a significant role in dietary habits, culinary traditions, folk medicine, myths, and culture since ancient times. This study aims to understand if the regular consumption of edible mushrooms as part of a balanced diet can have some specific beneficial effects on health, especially in preventive medicine. PubMed and Google Scholar were screened for relevant literature reviews, and five articles were included in this work. Overall, mushroom dietary intake was associated with reduced neoplasm incidence, particularly breast cancer, and improved glucose, lipid, and vitamin D levels. However, changes in cholesterol levels were not detected in all studies, and no significant effect was shown for modifications in blood pressure and body weight. In conclusion, the evidence available suggests that a balanced diet including a serving of edible mushrooms at least two-to-three times a week may decrease cancer and metabolic risk in the long run, thus contributing to reducing all-cause mortality risk. The quality of mushrooms and their nutritional characteristics is fundamental to ensure consumer product safety. Further studies should investigate in more depth the effects on health of different mushroom species consumed regularly and the exact minimum amount associated with significant benefits.

Blackcurrant (Ribes nigrum L.) and raspberry (Rubus idaeus L.) fruits, rich sources of phytochemicals such as polyphenols, have been shown to possess promising biological properties. Herein, both fruits from southern Italy have been extracted by maceration by using ethanol as the solvent and investigated for their potential pancreatic lipase inhibitory activity. The radical scavenging effects were also analysed by using the 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) tests. Our study showed that the extracts of both blackcurrant and raspberry have significant inhibitory activity against lipase with IC₅₀ of 5.1 and 30.2 μg/mL, respectively, better than the positive control orlistat (IC₅₀ of 37.1 μg/mL).

In recent years, the different dietary needs of consumers due to their health problems, such as food allergies and lactose intolerance, or lifestyle changes, well-being trends, and increasing awareness about environmental concerns, causes an increment in consumers’ demand to have more plant-based foods in the diet. In this regard, more sustainable alternatives for different food systems come into prominence, and the market size for new plant-based alternatives, especially for dairy products, is ever-increasing. Ice cream is a complex colloidal structure and is defined as a frozen foam that is considered a suitable matrix for plant-based milk substitutes. Although it is hard to obtain a stable colloidal ice cream structure when replacing cow’s milk with plant-based alternatives, the coconut-based, soy-based, and almond-based milk alternatives are regarded as some of the most suitable choices for ice cream production. According to studies, coconut milk’s fat and protein content helps the formation of emulsion and stabilization of the foam system. Also, it is indicated that soy-based ice cream is a good carrier for probiotics, has a better melting resistance, and has comparable sensorial properties with dairy ice cream when used together with milk alternative combinations. However, some technological, microbiological, and sensorial properties of plant-based ice creams were not similar to ice cream made with cow’s milk. Eventually, innovative approaches to producing ice cream with different milk alternatives could be promising and beneficial for the sustainable food industry and should continue to be developed to meet the current needs and interests.

To date, the most commonly used probiotics in the potential synbiotic combinations (SC) in breads belong to the family of Lactobacillaceae and Bifidobacteriaceae. However, Bacillus coagulans as a heat-resistant bacteria, and Saccharomyces boulardii, as a probiotic yeast, could be promising for use in SC bread. Inulin is the most commonly directly used prebiotic source in formulations of potential SC bread. Moreover, co-encapsulations of probiotics with prebiotics, mainly including different hydrocolloids, could be beneficial. Although the consumption of potential SC in bread, generally including Lactobacillus sporogenes and inulin, by diabetics had some health benefits, there is a need for more comprehensive clinical trials.

Consumers are faced with a multitude of hazards that may be present in the foodstuffs they consume. Legislation in the agri-food industry is a set of strict rules to be followed at every step in the process of releasing products. Quality assurance in Algeria is essentially based on legislation framed by the law on fraud repression and consumer protection, together with health law, phytosanitary law and veterinary law. This is in accordance with international standards, such as the Codex Alimentarius, the ISO standards and international legislation, including the Basic General Food Law (EC 178/2002) and the Hygiene Package, as well as HACCP requirements. Public authorities must take all necessary measures to guarantee safe and healthy food products. The State, through its services, is the guarantor of public health. Full article

T. molitor larvae were fed with wheat bran (W) and supplemented (1:1) with cucumber (C + W) or tomato (T + W) agricultural wastes, from conventional or ecological farming, for 6 weeks. Weekly and fortnightly measurements of larvae weight/tray and length were taken, respectively. At the end of the study, the fatty acid composition of the larvae was analyzed using GC-MS. On day 43, the weight of larvae supplemented with wastes almost doubled that reached by the control larvae (647–720 vs. 370 g/tray), which were 15% smaller. Supplementation decreased the larval fat content and increased the polyunsaturated fatty acids between 22–37%, with linoleic acid being the most abundant. Full article

The bakery industry generates substantial food waste, leading to global environment pollution and economic losses. However, these by-products contain valuable bioactive compounds, such as melanoidins, which are brown pigmented compounds with significant antioxidant, antimicrobial and anti-inflammatory properties, making them ideal functional ingredient. This study aimed to evaluate the optimal enzymatic extraction of melanoidins from bread crust using different proteolytic enzymes: pronase E, serine-endo-protease (SP), metalloenzyme protease (MP) and endoprotease papain enzyme (EP). While the yield of melanoidins from MP and EP was lower than that of pronase E, SP yield was significantly higher. No cytotoxicity of bioaccessible, gastrointestinal and colonic fractions was observed in the cell lines Caco-2, HUVEC and SHSY5Y. The antioxidant properties and ability to stabilize the hydroxyl radical were characterized in bioaccessible fractions of the four melanoidins extracts. Moreover, melanoidins positively influenced the intestinal microbiota by increasing beneficial bacteria like Bifidobacterium and Lactobacillus, while reducing non-beneficial bacteria such as Bacteroides spp. and Clostridium leptum, with particularly significant results for SP and EP enzyme extracts. In conclusion, SP and EP enzymes appear to be viable alternatives to pronase E for obtaining melanoidin extracts as functional ingredients. These enzymes offer potential cost advantages and contribute to the sustainable utilization of bakery by-product melanoidins in various food applications. Implementing these alternatives could help to reduce food waste, environmental pollution and economic losses in the bakery industry while promoting the use of valuable bioactive compounds.

A functional product obtained from beet molasses vinasse (V) was supplemented to hypertensive rats (SHR) to assess its preventive effects against high blood pressure and endothelial dysfunction. Fifteen potential bioactive compounds (including phenolic acids, flavonoids and terpenoids, and glycosylated compounds) were identified and quantified in V by HPLC-MS. The most notable finding of the study was that the blood pressure values remained similar to those at the beginning of the study in the SHR+V group. At the same time, they increased progressively in the SHR control group, reaching a significant difference of 16% (p < 0.05) after 5 weeks of supplementation. Quantitative PCR and Western blot analyses of the aorta demonstrated that V ingestion by hypertensive rats led to decreased ACE mRNA levels and higher SOD2 and eNOS gene expression via promotion of Nrf2 transcriptional activity and down-regulation of the NF-κB pathway. These results are associated with an increased antioxidant, anti-inflammatory, and vasodilatory response. In conclusion, the intake of vinasse-derived products could mitigate hypertension and associated endothelial dysfunction. Full article

Hyperglycemia is a significant risk factor in metabolic syndrome, contributing to the development of cardiovascular diseases and diabetes mellitus. Hyperglycemia increases ROS (reactive oxygen species) production via glucose oxidation and protein glycosylation, leading to cell damage. Our previous studies have highlighted the antioxidant properties of wine pomace products (wWPPs), a co-product of winemaking, and their ability to modulate oxidative stress. The objective of this study was to evaluate the protective effect of wWPPs against oxidative stress in hyperglycemic Caco-2 cells. They were treated with 1.5 μg GAE/mL of wWPP bioaccessible fractions, obtained from gastrointestinal digestion (WPGI) and colonic fermentation (WPF), under normoglycemic or hyperglycemic (35 mM glucose) conditions. After 24 h of treatment, cell viability, oxidative stress biomarkers and the expression of transcription factors and enzymes involved in cellular oxidation balance were evaluated. Hyperglycemia induced a 30% reduction in cell viability, which was restored to normoglycemic levels by WPF treatment. The bioaccessible fractions were able to counteract hyperglycemia-induced oxidative stress in intestinal cells, as evidenced by significant decreases in carbonyl groups and MDA levels (10 and 40%, respectively). Furthermore, hyperglycemia-induced NF-κB overexpression was also significantly reduced by WPGI and WPF pre-treatment (between 15 and 53%), modulating the redox activity. In conclusion, the bioaccessible fractions of wWPP, particularly WPF, demonstrated significant potential in mitigating hyperglycemia-induced oxidative stress and enhancing cell viability in Caco-2 cells.

The aim of this research was to determine the effects of the addition of defatted flaxseeds (3.0%, 6.0%, 9.0%, 12.0%, and 15.0%) on the selected quality features of liver pates. The quality of pates was characterized on the basis of sensory assessment and pH, water activity, water-holding capacity, drip loss during refrigerated storage, color and texture parameters. Results of the analysis showed that degreased flaxseed addition at a level of 3% had no significant impact on most of the analyzed physico-chemical and sensory characteristics of the pate. It was found that a higher level (especially 12–15%) of flaxseeds reduced pates’ sensory quality, mainly by increasing the intensity of the taste of the seeds. The largest tested addition of flaxseeds to the stuffing of pates resulted also in a change in color parameters by the seeds lowering the lightness (L*) and increasing the yellowness (higher +b* value), as well as increasing the penetration force and hardness and lowering the cohesiveness of the products. The positive effect of the addition of degreased flaxseeds, besides adding to the health value of pate, was also the improved water-holding capacity and reduced mass loss during refrigerated storage.

One promising avenue for prevention lies in the development of neuroprotective and antioxidant functional foods. To this end, a study focused on ten species from the Lamiaceae family, which have attracted attention due to their well-known antioxidant, anti-inflammatory, anti-obesity, and anti-cancer properties, among others. The interest in their pharmacological applications has grown significantly in recent years. In order to uncover the biological potential of these species, the study involved performing decoctions and evaluating both the total phenolic content (TPC) and antiradical activity. The results revealed that TPC values ranged from 59.97 ± 6.18 (Ocimum basilicum L. var minimum) to 374.0 ± 16.9 (Salvia officinalis L.) mg gallic acid equivalents (GAE)/g of dry extract (dw). Additionally, the IC₅₀ values for DPPH^• and ABTS^•+ scavenging activities varied between 21.55 ± 1.18 (Origanum vulgare L.) and 132.0 ± 15.3 μg/mL (O. basilicum var minimum), and from 14.79 ± 0.50 (O. vulgare) to 44.65 ± 2.34 μg/mL (O. basilicum), respectively. The observed strong antiradical activity holds great promise for the future development of functional foods aimed at combating the oxidative stress implicated in these diseases and promoting overall brain health. By harnessing the potential of these species from Lamiaceae family, we may pave the way for innovative approaches to tackle neurodegenerative and neuropsychiatric conditions. Full article

Despite innovative approaches to urban food production, skepticism towards vertical crops remains widespread, posing profitability risks for agricultural enterprises. To overcome these challenges and develop successful business models, identifying consumer acceptance barriers is crucial for engaging stakeholders, investors, and farmers in local food production. When introducing innovative food production methods, like vertical farming, it is essential to gain public approval. However, recent technological advancements, such as genetically modified crops and artificial radiation, have been met with doubt, leaving overall consumer opinions about vertical farming uncertain. In this context, the purpose of this paper is to analyze Italian consumers’ acceptance of vertical farming systems and products, aiming to understand the main drivers that influence their desire to purchase such products. The research, conducted in Italy from April to May 2023, gathered qualitative and quantitative data through an anonymous online questionnaire that was completed by potential consumers. A total of 258 respondents were eligible for data analysis. The survey assessed participants’ knowledge, attitudes towards agriculture and food, and perceptions of vertical farming using Likert scale evaluations. The findings showed that, although a large proportion of respondents expressed interest in purchasing vertical farming products, concerns related to cost, authenticity, and environmental sustainability pose challenges. The evidence that emerged provides a series of indications for understanding consumer preferences more in-depth and useful suggestions for companies that need to expand the vertical farming products market.

We examined the effects of an informative pitch and multisensory contexts as potential factors influencing individuals’ experience of tofu with soy sauce and the amount consumed outside the lab. Two hundred and sixteen participants watched one of two pitches (promoting either vegetarian diets or exercise) and were guided into one of three multisensory contexts (‘sustainable’, ‘meat’, or ‘neutral’ theme). Participants rated the aroma and appearance of soy sauce and the taste of tofu dipped in it using the intuitive ‘one touch’ EmojiGrid valence and arousal measuring tool. Our results showed that the ‘meat’ context increased arousal ratings for soy sauce and the tendency to consume more tofu relative to the other contexts. Pitch did not influence affective ratings or amounts consumed. We conclude that the multisensory context has the potential to positively affect peoples’ choices and perceptions of plant-based and sustainable food and promote its consumption. Full article

Food additives are substances of natural origin or obtained by chemical synthesis. Among these additives, food antioxidants play an essential role in preserving food quality by neutralizing free radicals and inhibiting oxidation reactions, which helps prevent food spoilage and maintain its freshness, taste, and nutritional value. In addition, dietary antioxidants may also be beneficial to health. This is particularly the perception that consumers have in relation to antioxidants of natural origin, such as plant extracts. In this paper, we focused on the case of rosemary extract as a food additive which is authorized in many countries, including the United States and Europe, under the code E392. Through the examination of patent documents available in specialized databases and using appropriate keywords, our research made it possible to go back in time to first show the uses of rosemary extract and then specify the exploitation of rosemary extract in the field of food. We selected 411 relevant documents (granted patents and patent applications), almost 40% of which were filed in China. The first patent found was published in 1984, and it concerned a method to obtain a highly effective antioxidant from rosemary suitable for preventing the oxidation of food. This patent was followed by others which claimed, among others, more effective methods of making rosemary extract. More recently, innovations have focused on the synergistic effect of rosemary extract with other compounds, particularly for the antimicrobial action of food preservation. Full article

Foods based on plant proteins have increased in recent years. Thus, this study aimed to establish the potential of rye protein hydrolysates to release bioactive peptides to treat non-communicable diseases. Rye protein isolate was obtained using the solubilization–precipitation method and hydrolyzed with alcalase and flavourzyme. Hydrolysates were assessed for antioxidant, antihypertensive, and anti-diabetic properties. The rye protein isolate showed a protein content of 51.06 ± 1.15%, and its hydrolysates showed antioxidant, antihypertensive, and anti-diabetic capacities of 34.77 ± 0.59, 86.15 ± 1.15, and 40.62 ± 2.61% for flavourzyme, while for alcalase they were 78.58 ± 1.04, 86.76 ± 2.02, and 63.70 ± 1.27%. Hydrolysis with alcalase was the greatest, and the multifunctionality obtained was better than in similar studies. Full article

Lactic acid bacteria (LAB) have a vast genetic potential and are used in food production. The aims of this work were to identify forty-six 16S ribosomal gene sequences of LAB isolated from goat’s raw milk cheeses and to evaluate the phylogenetic relationship between the sequences. Using Sanger sequencing and the BLAST algorithm, the species were identified. Phylogenetic analysis was carried out using the R 4.3.0 software, and the genetic distance was calculated using the MEGA 11 software. The phylogenetic tree revealed variability between sequences of the same species, which may have implications for the technological capabilities of LAB sought for the production of cheeses of standardized quality.

Agro-industrial waste biotechnology refers to applications of biotechnological processes and techniques to convert agricultural/agro-industrial waste into valuable products. The food and agricultural industries generate significant amounts of waste during processing and production, including by-products from crops, fruits, vegetables, and other agricultural products. By using biotechnological techniques such as fermentation, enzymatic conversion, and microbial processes, it is possible to convert these waste materials into various useful products. But how do people receive this information (and others generated from this field of science) in their daily lives? This study aims to cover this topic and provide an approach to how it ultimately relates to people’s purchasing options. A total of 120 people (37.5% men, 62.5% women) from six different parts of Greece (34.2% from Lemnos) took part in this survey. The key result of the survey was that 85.0% of respondents responded positively to their awareness of sustainability/circular economy. In addition, 64.6% of participants answered negatively when asked (whether they thought the information they received from the media and public bodies on the topic of sustainability/circular economy was sufficient for them. Some 36.7% of participants responded that they would be willing to pay 20% more to purchase a product that itself (or a component of it) is produced through biotechnological applications, and 46.7% responded that they would be happy to pay more, but that cost coverage is important.

Various strategies to contain the spread of COVID-19, including trade restrictions and lockdowns, challenged the movement of produce from farm-to-fork. Business closures reduced demand for produce, which affects Filipino farmers. As an alternative, e-commerce surged as a safer way to shop for produce. This study aimed to assess the willingness of Filipino farmers to adopt e-commerce using an extended Technology Acceptance Model (TAM) to measure their perceived innovativeness (PI), perceived usefulness (PU), perceived ease of use (PEOU), perceived cost (PC), information awareness (IA), and social influence (SI). Using Spearman’s rho, it was found that PI (p = 0.001), PU (p < 0.001), IA (p < 0.001), SI (p < 0.001), and monthly internet data allocation (p = 0.001) were all correlated to farmers’ willingness to adopt (WTA) e-commerce.

Sensory linguistics and food science meet in the field of consumer studies. Glossaries of emotions and tools for measuring feelings related to food consumption are being developed in order to understand consumer preferences, and to gain insight to be used in consumer-focused product development and marketing. Although there are lexicons and tools for measuring emotions in various languages, there are none in Greek, leading to reduced competitiveness of Greek products and companies. As is the trend in cross-cultural studies, for the present study, an English emotion measurement tool was translated into Greek. The consumers with whom the translated tool was tested reported that many of the emotions contained were inappropriate for the task. Thus, the need to develop a lexicon in Greek from scratch was identified. Following the methodology for the development of the EsSense Profile an established commercial measurement tool, input from consumers was collected using questionnaires of various forms and for a variety of foods and beverages. Additionally, language sources were used for the development of the new Greek tool. The World Wide Web and Instagram were also used as linguistic resources, a practice that does not belong to standard methodology but follows the current literature. The new emotion lexicon was used as a measurement tool and compared with a broadly used measurement tool that contains emojis. Full article

Spent coffee grounds (SCGs) are currently considered abandoned landfill waste despite retaining valuable organic compounds, especially with a high protein content of 16.64 ± 0.13 g/g dried SCGs and a high oil content of 15.48 ± 0.17 g/g dried SCGs. As a result, SCGs could serve as a potential source of valuable ingredients. However, utilizing a single technical strategy of alternative green extractions was insufficient for extracting the target compounds and hydrolyzing proteins. This work aimed to optimize the operating parameters of enzyme-assisted extraction (EAE), microwave-assisted extraction (MAE), and subcritical water extraction (SWE) using a response surface methodology. The results showed that EAE, at a papain-to-substrate ratio (E/S) of 0.5 and a duration of 15 min, generated a %DH of 93.39% and provided a water soluble protein concentration (WSPC) in the range of 400 to 800 µg/mL. Moreover, MAE provided a maximum %DH of 9.72% at 600 watts and 10 min, while SWE produced a maximum %DH of 13.41% at 160 °C in 17.5 min. However, the WSPCs of MAE and SWE extracts were comparable at ~250 µg/mL. The combination MAE−SWE enhanced the %DH of hydrolysates by more than the combined SWE−MAE, SWE, and MAE. However, the effects of differential hydrolysis on bioactivity are not directly correlated with %DH. In this study, the highest antioxidant activity was found at an E/S of 0.5 and in 15 min for EAE, at 350 W and in 10 min for MAE, and at 160 °C and in 30 min for SWE. This work demonstrated that the valorization of SCGs not only reduces the amount of waste but also yields functional cosmeceutical and nutraceutical ingredients. Full article

Purple sweet potato has been gradually increasing in terms of planting and consumption but, after harvesting, the leaves of the sweet potato are often discarded as waste or used for animal feed. The aim of this study was to determine the effect of drying methods on the quality of sweet potato leaf powder and its storage capacity. The nutritional and antioxidant properties of powder were analyzed. The results showed that hot air-drying could preserve the antioxidant properties more than the sun-drying method. Both methods could produce a product with high nutritional value, especially a high amount of protein and fiber. This could be considered as a supplementation ingredient for the food industry. Moreover, after storage at room temperature for 12 weeks, a slight increase in moisture content and decrease in antioxidant properties were found. Further, the application of this ingredient should be further investigated in food application to improve the income for local farmers as well as reduce the environmentally harmful waste.

Campylobacter spp. are the main cause of foodborne gastroenteritis worldwide, and the biofilm growth mode seems to play a key role in their prevalence. In this work, the effect of lactic acid (LA) on planktonic growth and biofilm production by eight Campylobacter spp. raw chicken meat isolates was investigated using polystyrene and stainless steel as the abiotic substrata. Results revealed that the minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and minimum biofilm inhibitory concentration (MBIC) values of LA against the Campylobacter isolates ranged from 1024 to 4096 μg/mL depending on the isolate, mode of growth (planktonic vs. biofilm; single vs. mixed culture), and the growth medium. Overall, the results of this work offer insights into the biofilm control of a pathogen of public health importance. Full article

Artisanal fermented products constitute a worthwhile source of autochthonous lactic acid bacteria (LAB) with biopreservative, technological and organoleptic potential. This study aimed to characterize the fate of autochthonous LAB in artisanal goat’s raw milk fresh cheeses at different temperatures by using an omnibus (one-step) modeling strategy. Lab-scale cheese prototypes (10 g) were artisanally elaborated from goat’s raw milk and stored at 4, 12, 18 and 25 °C. LAB were enumerated (ISO:15214) during cheeses shelf-life. Growth models were fitted to the data, producing maximum growth rates averaging 0.345 ± 0.162 and 3.338 ± 0.907 ln CFU/g/d at 4 and 25 °C, respectively, and population increases averaged 3.388 ± 0.203 and 7.877 ± 1.480 ln CFU/g. The omnibus modeling approach allowed for the definition of a general model that describes autochthonous LAB growth with a correlation coefficient of 0.991 between experimental and estimated data. These results contribute to the better understanding of autochthonous LAB in artisanal cheeses for their further use as potential new-generation biopreservatives. Full article

Gluten-free bread is a new option for a population unable to digest gliadins and glutenins. This study compared the texture and color of four formulations, each containing varying amounts of hydroxypropyl methylcellulose (HPMC), psyllium, xanthan gum, and water. It was found that removing xanthan gum reduced the hardness and gumminess of the breadcrumbs. Increasing the amount of psyllium increased gumminess and redness. Interestingly, increasing the amount of HPMC in the formulation did not show significant differences. This suggests that HPMC may not have a pronounced effect on texture and color compared to the control formulation. Full article

Edible bird’s nest (EBN) is a valuable and nutritious food tonic made from the saliva of swiftlet birds. EBN has been consumed for centuries due to its high nutritional value. Proteins are the main nutrient in EBN. However, studies investigating the functional proteins in EBN are still limited. Therefore, the present study aims to characterize the functional proteins from EBN using proteomic-based techniques. In addition, the molecular characteristics of the functional proteins were analyzed using sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS-PAGE). The results showed that 0.951 ± 0.03 mg/mL of functional proteins were successfully extracted from the EBN. Several distinct protein bands in the range of 35–135 kDa were profiled from the EBN. Using ultrahigh-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (UHPLC-Q-TOF-MS-MS), a total of 51 proteins were identified from the EBN. The protein sequences were processed in the BIOPEP database to predict the potential biological activity of EBN proteins. The prediction results suggest that EBN proteins potentially possess antioxidant, anti-inflammatory, immunostimulatory, antiamnestic, antihypertensive (angiotensin-converting enzyme (ACE) inhibitors), antidiabetic (alpha-glucosidase inhibitors, alpha-amylase inhibitors, dipeptidyl peptidase IV inhibitors), and antithrombotic properties. The antioxidant properties (DPPH-scavenging activity (20.84% ± 3.43) and ABTS-scavenging activity (31.49% ± 1.66)) and anti-inflammatory properties (inhibition of nitric oxide (NO) production (21.30% ± 4.41) and inhibition of albumin denaturation (25.30% ± 0.32)) were experimentally validated. In conclusion, the results suggest that functional proteins from EBN are potentially functional ingredients in the nutraceutical and food industries. Full article

Nigella sativa, an annual herbaceous flowering plant of the Ranunculaceae family, is considered an important medicinal plant due to the presence of several bioactive compounds in its seeds, including both volatile and non-volatile compounds. The cultivation of numerous genotypes of N. sativa is seen in different parts of the world with varying compositions of such chemical compounds. Since the variation in composition determines the quality grade of the seeds, this study was carried out to explore the compositional variation of twelve different genotypes of N. sativa cultivated in Central Queensland, Australia. The results showed total phenolic content (TPC), FRAP and CUPRAC (antioxidants), and thymoquinone in the range of 291–529 mg GAE/100 g DW, 703–966 mg TE/100 g DW, 2533–3416 mg TE/100 g DW, and 219–349 mg/100 g DW, respectively. The highest values of TPC, thymoquinone, FRAP, and CUPRAC were observed in genotypes AVTKS#E, AVTKS#F, AVTKS#4, and AVTKS#D, respectively. The lowest values of TPC and FRAP were observed in genotype AVTKS#24, and the CUPRAC and thymoquinone were lowest in genotype AVTKS#23 and AVTKS#1, respectively. Monomeric anthocyanins were absent in the methanolic seed extracts of all nigella genotypes. There was a strong positive correlation among the TPC, CUPRAC, and FRAP. However, despite thymoquinone being reported as a strong antioxidant in the literature, there was no significant correlation of thymoquinone with TPC or CUPRAC, and only a weak positive correlation with FRAP. Overall, the genotypes with comparatively higher values of thymoquinone, TPC, and antioxidant capacity (both FRAP and CUPRAC) showed particular potential for breeding programs. Full article

In recent years, shrimp consumption has increased, resulting in massive amounts of waste. In this study, different extraction techniques, namely, ultrasound-assisted extraction (UAE), subcritical-water extraction (SWE) and conventional extraction (CE), were tested to evaluate their efficiency in recovering bioactive compounds from shrimp shells. SWE performed at 200 °C was the extraction technique that allowed for the highest recovery of polyphenolic and carotenoid compounds (5.43 ± 0.17 mgGAE/g dw and 59.9 ± 1.0 μg carotenoids/g dw) as well as the highest antioxidant activity in ABTS and FRAP assays (7.93 ± 0.01 and 4.35 ± 0.31 mgAAE/g dw). These results demonstrate the potential of shrimp shells, which can be further incorporated into other products. Full article

Argentina’s prominent global position in honey production is due to its extensive agroecological diversity. This study assessed the influence of geographical origin on the physicochemical properties of honeys from southeastern Entre Ríos. In total, 104 honey samples from Gualeguaychú (GU), Islas del Ibicuy (II), and Concepción del Uruguay (CU) (2020–2022) were analyzed. Statistically significant differences (p < 0.05) were observed among districts: the II samples displayed the lowest values (color, conductivity, acidity, pH, and ash), the GU samples showed moderate values, and the CU samples exhibited the highest values, except for humidity. Chemometric analyses explained 75.5% of data variability (PCA) and successfully classified 85.3% of the samples by their origin (LDA). These findings bear implications for product differentiation and market value enhancement in Entre Ríos’ honey industry, serving as a foundation for future quality control and origin identification endeavors.

The aim of the present work was to study the effect of solvent (50%:50% ethanol:water; 100% ethanol, and 100% water) on the extraction of total phenolic content (TPC) and total antioxidant activity (TAC) from pomegranate peel and broccoli leaves through microwave-assisted extraction (MWAE). In pomegranate peel, TPC after 100% aqueous MWAE (119.6 g GAE/kg dw) increased 1.6-fold more than 100% ethanolic extraction (74.2 g GAE/kg dw). Regarding broccoli leaves, TPC after 100% aqueous MWAE (28.4 g GAE/kg dw) increased 3.4-fold more than 100% ethanolic extraction (8.5 g GAE/kg dw). In this sense, TAC reported similar behavior in broccoli leaves’ extraction (DPPH and ABTS values ranged between 1.1–3.5 g TE/kg dw and 2.4–3.8 g TE/kg dw, respectively), while no great differences were found among solvents during the pomegranate peel extraction (DPPH and ABTS values ranged between 3.5–3.7 g TE/kg dw and 3.7–4.3 g TE/kg dw, respectively). Therefore, aqueous MWAE could be considered as a green technology to recover TPC from horticultural by-products. This could be of great interest for industry, and should contribute to the problem of food loss. Full article

The Mediterranean diet (MD) is rich in plant-based foods that provide antioxidants associated with a lower risk of chronic degenerative diseases, with Valencia’s paella being a representative dish. Antioxidants can be classified as extractable or non-extractable. Extractable antioxidants are easily extracted using aqueous and organic solvents. On the other hand, non-extractable antioxidants are those that are bound to the food’s cellular matrix and cannot be easily extracted. This study provides information on these properties in paella, evaluating total polyphenols (TP) (Folin-Ciocalteu method) and total antioxidant capacity (TAC) (TEAC and ORAC). Per 100 g, the total values ranged from 835.65 mg GAE/dry weight (DW) for TP to 1286.80 and 77,803.54 µM Trolox/DW for TEAC and ORAC (TAC), respectively. Approximately 82% of the TAC comes from non-extractable antioxidants. Furthermore, there is an antioxidant synergy in a portion of paella compared to the sum of its ingredients: TP (478.74 vs. 168.37), TEAC (2111.10 vs. 1669.98), and ORAC (127,642.42 vs. 47,023.59), respectively. The results can contribute to expanding the information present in TAC and total polyphenol databases, as there are few studies on complete dishes, and they tend to significantly underestimate the total values due to the lack of determination of non-extractable antioxidants.

“Chouriço de carne” is a Portuguese ready-to-eat dry fermented sausage which relies on effective spontaneous fermentation to ensure its microbial safety and desired organoleptic properties. This study aimed to assess selected microbiological and physicochemical characteristics of artisanal chouriço produced by 14 different regional producers. Aerobic mesophilic bacteria, lactic acid bacteria, Staphylococcus aureus, Clostridium spp., Listeria spp. and Salmonella spp., in addition to pH, water activity and moisture, were evaluated for each of 70 samples. Principal Component Analysis of all these attributes was performed to build quality maps of the analyzed lots. The results showed great variability between sausages of different producers within the same geographic region, and S. aureus, Clostridium spp., Salmonella spp. and Listeria spp. were identified in sausages of several producers, highlighting the need for stricter microbiological control and standardization of production processes among artisanal producers of chouriço.

Plant sterols (PSs) have reported benefits in alleviating colitis in mice, but the mechanisms involved require further investigation. This study aimed to evaluate the effect of a dietary supplement containing PSs (PS-DS) on inflammation biomarkers in a mice model of chronic ulcerative colitis induced by dextran sulfate sodium (DSS). C57BL/6J mice (n = 34) were exposed to 1.5% DSS in drinking water for three 5-day periods, with 10-day rest intervals in between. The mice received daily PS-DS (35 mg PS/kg) or placebo by oral gavage, either simultaneously (treatment) or 30 days prior (pre-treatment) to DSS exposition. After euthanasia, myeloperoxidase (MPO) activity and the levels of pro- (TNF-α and IL-6) and anti-inflammatory cytokines (IL-10) in the colonic tissue were analyzed. PS-DS treatment reduced (vs. DSS + placebo) myeloperoxidase (MPO) activity (2.6 ± 0.2 vs. 2.1 ± 0.1-fold change) and levels of TNF-α (85 ± 11 vs. 39 ± 7 pg/mg protein) and IL-6 (214 ± 26 vs. 128 ± 18 pg/mg protein), increasing the levels of IL-10 (46 ± 5 vs. 136 ± 16 pg/mg protein). PS-DS pre-treatment provided a greater inhibition (vs. treatment) of MPO activity (2.1 ± 0.3 vs. 1.3 ± 0.1-fold change) and a greater increase in IL-10 levels (50 ± 9 vs. 178 ± 30 pg/mg protein). These findings suggest that PS-DS has the potential to alleviate colitis in mice by modulating the inflammatory response and reducing oxidative stress. However, studies in humans are required to validate and fully understand its anti-inflammatory effect. Full article

Tenebrio molitor larvae were fed with wheat bran and supplemented (1:1) with tomato or cucumber agricultural waste for 6 weeks. After supplementation, larvae were dried in a pilot-infrared oven (68 °C for 4 h) and ground to obtain the flours. The quality attributes and nutritional value of insect flours differed based on the supplemented diet. Unsaturated fatty acids, proteins, starches and certain vitamins were enhanced in flours from supplemented larvae. Therefore, tomato and cucumber waste can be revalorised as supplements of T. molitors’ conventional diet to obtain insect flours with higher nutritional values and acceptable-quality attributes.

The aim was two-fold: to characterise the risks of lead (Pb) in Agaricus bitorquis collected in the city of Leicester (England), and to evaluate its presence in urban topsoils. Pb was monitored by ICP-MS in twenty-two homogenised mushroom samples (caps and stipes) mineralised with HNO₃/H₂O₂ [LoD = 0.872 mg/kg dry weight (dw)]. Moreover, 450 topsoil samples were collected from 18 urban parks across Leicester; Pb was also measured by ICP-MS after appropriate digestion (LoD = 0.698 mg/kg). Levels were significantly higher in the mushroom caps (p-value = 3 × 10⁻⁵); median and ranges are provided in mg/kg dw: 2.461 (1.806–6.664) vs. 1.579 (0.988–4.223). Concentrations were much higher than those reported in sixteen A. bisporus (median < 1.0 mg/kg DW) specifically cultivated in high-traffic areas in the inner city of Berlin, suggesting some contamination by Pb. All caps monitored exceeded the established maximum concentration limit for Pb in cultivated mushrooms in the European Union (3 mg/kg dw), in line with the high accumulative metal capability described in the literature for Agaricus spp. Although non-carcinogenic risks characterised for Pb were negligible in the monitored mushrooms, a high consumption of wild green edibles in Leicester’s city should be limited as there are multiple additional sources of Pb and other metals, and they should be substituted by cultivated edibles where possible.

Wine pomace, also mentioned as grape pomace (GP), is a byproduct of the wine industry, containing about 50% grape skins, 25% grape seeds and 25% stems. These wastes are of great value and great potential as a source of biologically active compounds. This opens up new prospects for the rational use of GP in the food industry. It is no coincidence that numerous new technologies for processing these byproducts have recently emerged to create a wide range of diverse new food products by enriching traditional foods with antioxidants, dietary fiber and mineral compounds. The most popular GP processing products are extracts and powders. Powders do not require special storage conditions, and they are highly adaptable, mixing well with other types of food raw materials, especially loose ones. Therefore, they are widely used in such products as bread, cookies, pasta, muffins, etc. Grape powders improve the structure of the dough, slow down the oxidation of fats, for example, in cookies, and increase the nutritional value of flour products. Finally, we will discuss these perspectives on the use of grape pomace as an ingredient in the formulation of flour-containing food products. Full article

Krill oil (KO) and the impregnation process to enrich food matrices with bioactive compounds have become relevant. The impregnation process of KO microcapsules into Golden apple tissue was evaluated in this study. A KO emulsion was used at different temperatures to impregnate Golden apple slices. The results show that an increase in temperature causes greater removal of water and penetration of the KO microcapsules. At 60 °C, the volume changes of the samples were evident, obtaining the highest concentration of astaxanthin. Through the impregnation process, it is possible to produce a new food product with potential functional properties. Full article

Bovine whey remains a common pollutant from food, and diverse strategies to mitigate it have been formed. Therefore, this study aimed to generate a functional ingredient from whey hydrolysis to be incorporated into beverage formulations. Hydrolysis at pH = 8 for 7 h was performed in order to determine the sample to be added to the beverage. It was elaborated according to a local producer, and its ACE inhibition capacity was tested. Kinetics showed that the degree of hydrolysis only significantly differed during the times of 0, 4, and 7 h. The exact times were submitted to the ACE inhibition test, but only 0 and 7 h showed higher activity (32.41 ± 0.63 and 29.63 ± 1.10%, respectively). As no statistical differences were found, both hydrolysates were incorporated into the beverage, expressing an antihypertensive capacity of 74.84 ± 1.39 and 78.76 ± 1.39%, respectively. A better sensorial profile was determined in the beverage made with 7 h hydrolysate, where a less salty taste was identified. Thus, pancreatin hydrolysis of whey was found to generate peptides with antihypertensive activity and improved acceptance characteristics. Full article

Goat milk is a vital, sustainable dairy product source that contributes significantly to the global dairy market. Different goat breeds may produce milk with varying compositions during different lactation seasons. Therefore, milk composition and quality need to be monitored. As a versatile and non-destructive method, Near Infrared Spectroscopy (NIRS) offers the potential for evaluating various milk parameters. In this study, we aim to establish NIRS models for classifying goat’s milk samples between the native Red and Alpine Breed at first and fifth lactation season. Our objective is to assess the efficacy and cost-effectiveness of NIRS as a viable alternative to traditional laboratory techniques. Forty-five milk samples were collected from two breeds, French Alpine goats, and native Red goats. Within each breed, half of the samples originated from goats in their first lactation season and the other half from goats in their fifth lactation season. The NIRS measurements were conducted using homogenized, untreated, and diluted milk samples. The experiment was performed with a benchtop spectrophotometer (740–1700 nm). Qualitative analysis using linear discriminant analysis (LDA) was conducted, demonstrating the feasibility of NIRS in effectively classifying samples. The achieved accuracy ranged between 67.19% to 100%, depending on the breed and lactation period. These findings underscore the potential of NIRS as a rapid, non-destructive analytical tool for quality monitoring and milk analysis. Its insights guide decision-making in nutrition, agriculture, food production, and public health. By exploiting on the distinct attributes of goat milk originating from various breeds at different lactation periods, we can offer a wide range of appropriate and varied food choices tailored to distinct population groups.

Oat (Avena sativa L.) grains are an important source of protein, minerals and oil. They contain at least twice as much fat as other common cereals, such as wheat, barley or rye, and the fat contained in oat grains significantly contributes to their properties, including improved calorific value and nutritional quality. Heat treatment, particularly roasting, has long been considered the essential method of processing grains, as roasting effectively extends shelf life, provides a pleasant roasted flavor and improves taste. The paper covers the improving effect of the roasting process of the whole oat grain on the quality of the oil contained in the grains. A differential scanning calorimeter coupled with a high-pressure cell has been used to determine the oxidative stability of oil. A calorimetric bomb was applied to determine the whole grain calorific value and GC (Gas Chromatography) determined the fatty acid composition of oil. Full article

Onion is one of the main crops in the world and there has been an increase in the demand for processed onion in the form of frozen and freeze-dried chopped onion in the last decade, with a detrimental impact on the environment. Onion byproducts (tops and bottoms of onion bulbs, onion skins, and undersized, malformed, diseased, or damaged bulbs) are a rich source of dietary fiber and bioactive compounds, representing a sustainable alternative to the use of traditional ingredients in the formulation of food products for the application of the circular economy concept. The aim of this work was to study the potential of onion byproducts as a functional ingredient by determining their in vitro bioactive properties. For the onion byproducts—skin (OS) and pulp with 9% of skin (OP)—proximal analysis was performed (AOAC, 1999): moisture, ash, proteins, fat, total dietary fiber (TDF) and total carbohydrates by difference. Bioactive properties were assessed by determining the total phenolic compounds (TPC, Folin–Ciocalteu method), antioxidant capacity (ABTS, ORAC-FL, and HORAC methods), and α-glucosidase inhibition capacity. Among the most relevant results of the proximate analysis, OS showed 70 ± 3% of TDF. OS showed the highest TPC (113 ± 7 mg GAE/g) and antioxidant capacity (699 ± 94 and 1782 ± 92 µmolTE/g for the ABTS and ORAC-FL methods, respectively, and 46 ± 2 mg chlorogenic acid/g for the HORAC method; p < 0.05), as well as the highest α-glucosidase inhibition capacity (lowest IC₅₀, 447 ± 40 and 625 ± 58 µg/mL for OS and OP, respectively). In conclusion, onion byproducts present potential as a functional ingredient because of the evaluated health-promoting effects, with a subsequent positive environmental impact by applying the circular economy concept.

Recently, researchers have developed new heat transfer fluids that have high thermal conductivity, heat capacity, and low viscosity for food applications. Because the thermal conductivity of nanoparticles is higher than base fluids (water, ethylene glycol, and so on), nanofluids (NFs) are characterized by high performance in heat transfer operations. In this study, the aim was to determine the effect of NFs used in heat transfer equipment on the heat transfer coefficient using Analysis of Covariance (ANCOVA), which is an optimization test. For heat transfer modeling of tomato juice, the effect of alumina content in NFs on Reynolds Number (Re) and overall heat transfer coefficient was evaluated. For heat transfer modeling of milk, the effect of carbon nanotube content in NFs on Peclet Number (Pe) and convective heat transfer coefficient was assessed. As a result, it was determined that Re and alumina content to be crucial in the heat transfer of tomato juice within their p-values. However, in milk production heat transfer, carbon nanotubes had no crucial importance. Full article

Third-generation (3G) rice pellets were obtained using rice flour (RF) and rice grits (RG), raw materials of similar compositions but different particle sizes. The samples were mixed with water to 25% moisture and extruded using a laboratory single-screw extruder (Kompakt KE 19/25 extruder) and three compression ratios (1:1, 2:1, and 3:1). The pellets were expanded using a microwave oven subjected to 1000 W/g power. After evaluating the expansion kinetics and the sectional expansion index (SEI), it was observed that the 3:1 compression ratio allowed for greater expansion, while the particle difference showed no significant difference (p > 0.05) in the SEI.

This study aimed to characterize special micronized wholemeal flours with a fine granulation size of less than 160 μm. The flours under investigation included wheat, rye, spelt, barley, buckwheat, sorghum, and teff. Various parameters were investigated to characterize the flours, including moisture, energy value, fat, carbohydrates, sugars, total protein, ash, and total dietary fiber (TDF). The falling number of the flours was assessed using the Hagberg–Perten method. Furthermore, the pasting properties of tested flours were analyzed using an amylograph, and a Rapid Visco Analyser (RVA). The water absorption of the wholemeal flours was examined using a farinograph. Additionally, the technological quality of the tested material was assessed based on the water (WRC) and sodium carbonate Solvent Retention Capacity (SRC) profile. Among the analyzed micronized flours, special wheat flour (WWF) had the highest nutritional value, and rye flour (WRF) was characterized by the lowest nutrient content and the highest amylolytic activity. The lowest levels of water absorption were found in special teff flour (WTF). The lowest TDF content and amylolytic activity were found in special buckwheat flour (WBWF). Full article

In recent years, scientific research has focused on studying Andean roots and tubers due to their attractive agricultural and nutritional qualities; however, as they contain a high level of moisture, it is imperative to dry them to extend their useful life. Likewise, analysing food-drying kinetics and food stability (regarding water activity) is essential to control moisture removal and the marketing progress. The drying process carried out in this study (65 °C for 8 h) showed three clear stages: adaptation, the drying period at a constant velocity, and a third stage with a gradual drop in the drying rate. The experimental data were satisfactorily adjusted to seven mathematical models, with the Page model highlighted since it presented higher coefficient-of-determination values. Likewise, this model estimated that the mean-error and percentage-of-relative-mean-deviation values were less than 1. The isotherms showed a type-II sigmoidal shape, showing that the samples were hygroscopic due to the structural changes undergone by the matrix during the process. Finally, the GAB model showed a higher coefficient of determination. All the Andean tubers and tuberous root flours must be dried until reaching a humidity below 10 g_water/g_{dry mass} and stored in environments with a relative humidity lower than 60% to remain stable for longer.

This article reports on a pilot experiment conducted on STEM teaching (Science, Technology, Engineering, and Mathematics) within the context of orientation teaching, wherein young pupils take on the role of “young researchers”. Twenty-six pupils participated in this research, and 18 of them evaluated 20 commercial yogurts (banana, vanilla, strawberry, and plain yogurt). They assessed acidity, sweetness, odor, texture, taste, and overall acceptability using a 5-point scale. Data were analyzed through non-parametric tests, box-whisker plots, and Principal Component Analysis. Statistics point out that for teenagers, overall acceptability was directly related to sweetness (0.695), odor (0.587), and taste (0.861), and indirectly related to acidity (−0.517). In addition, non-parametric tests show high variability within the dataset, with a non-normal distribution of sensory scores. Full article

This study presents the results of an analysis of amaranth oil. The aim of this research was to determine the physicochemical properties of the oil, particularly its thermal properties. The oil obtained from expanded amaranth seeds was tested. The obtained results proved the oil’s good resistance to oxidation. Three peaks present on the DSC melting curves of amaranth oil were associated with the presence of low-melting-point triacyloglicerols with polyunsaturated fatty acids (the first peak) and a medium-melting-point fraction rich in triacyloglicerols with monounsaturated and saturated fatty acids (the second and third peaks). The composition of fatty acids in the studied amaranth oil showed a high content of essential fatty acids. Full article

Some of the properties that have been attributed to honey are antioxidant, anti-inflammatory, and antimicrobial effects, especially due to its content of bioactive compounds, mainly phenolic compounds (PCs), whose content varies greatly depending on the variety, origin, agronomic conditions, harvest season, and climate. The aim of the present study is to characterise 21 honeys from Sierra Nevada (Granada). High-performance liquid chromatography coupled to quadrupole-time of flight mass spectrometry (HPLC-ESI-QTOF-MS) was used. Mass accuracy and true isotopic patterns in both MS and MS/MS spectra enabled the tentative identification of 58 PCs, including flavonoids, phenolic acids and derivatives. The average content of PCs was 83.01 ± 16.36 µg/g, with flavonoids accounting for more than 85%. The most abundant compounds were naringenin (16.88 ± 3.15 µg/g), pinocembrin (12.33 ± 2.92 µg/g), chrysin (12.21 ± 2.09 µg/g), carnosol (9.52 ± 2.90 µg/g), galangin (5.41 ± 1.68 µg/g), and apigenin (5.24 ± 0.89 µg/g). Due to this interesting composition, more studies are necessary to determine if the extreme environmental conditions of Sierra Nevada cause abiotic stress in the plants located there, fostering this concentration of PCs.

Rambutan seeds (RS) are industrial waste often generated in the canned fruit industry. The aim of this study was to extract polysaccharides from defatted rambutan seeds or crude polysaccharides (POLS-DRSs) with subcritical water. Defatted seed powder (DRS) was extracted by hot-water extraction (HWE) at 100 °C as a reference condition. Subcritical water extraction (SWE) was performed at 120–140 °C and an initial pressure of 2 MPa. A sample-to-water ratio of 1:10 (w/w) and an extraction time of 15–60 min were used for both methods. The results show that gravimetric extraction yields of 53.01 g/100 g DRS and 7.71–41.70 g/100 g DRS were obtained from HWE and SWE, respectively. Additionally, HWE provided a total sugar content of 30.75 g/100 g POLS-DRSs, while SWE generated a total sugar content in the range of 27.00–49.76 g/100 POLS-DRSs. The antioxidant activities of POLS-DRSs were measured with a 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. An amount of 40 mg of POLS-DRSs obtained at 120 °C after 60 min provided the highest DPPH activity of 82.93% inhibition. The POLS-DRSs were suitable for growing microorganisms because they had a high sugar content and a low total phenolic content. A prebiotic activity assay will be carried out in future studies.

Umbu (Spondias tuberosa) is a Brazilian Caatinga native fruit that has socioeconomic importance. Pulp is the main product of its agro-industrialization. However, de-pulping gives rise to about 25% residue. It is known that fruit peels and seeds are composed of macro and micronutrients as well as bioactive compounds, offering the umbu residue an opportunity to add value to the fruit agro-chain. As the recovery of bioactive compounds from umbu seeds has not yet been optimized, this work aimed to evaluate their recovery through a more sustainable approach, using propylene glycol as a solvent in microwave-assisted solid–liquid extraction. For that, an experimental design varying the propylene glycol percentage (15–85%) and temperature (59–201 °C) was adopted. The total phenolic compounds (TPC) and antioxidant capacity according to DPPH^• were evaluated as responses. The highest values were found at 201 °C and 50% propylene glycol (3242 mg GAE/100 g and 162 µmol Trolox/g for TPC and DPPH^•, respectively). The values observed were, at least, 8 times higher than those obtained in the worst experimental condition (25% propylene glycol and 80 °C), showing that the independent variables had an effect on the evaluated responses (p < 0.05). All models were significant, displaying p value < 0.05, and no lack of fit was observed. High adjusted R² values (>0.95) confirm the good fit of the data to the models. Thus, microwave-assisted extraction employing propylene glycol as a solvent could be a more sustainable method for the use of umbu seeds. Full article

Acetic acid bacteria (AAB) are ubiquitous wine spoilage microorganisms causing significant economic damage to winemakers. Considering difficulties in their isolation through traditional microbiological methods, it would be advantageous to detect them using molecular methods at all stages of winemaking and, thus, prevent wine spoilage. In this research, we analyzed wines, musts and grapes of 13 varieties grown in different regions of the Republic of Moldova. The DNA was extracted and analyzed via PCR using home-designed primers to detect Acetobacter aceti and Acetobacter pasteurianus. Generally, samples with no detectable amounts of AAB in either musts or wine had volatile acidity within the acceptable limits. Only one grape (Rara Neagra) had detectable amounts of AAB (A. pasteurianus) at all analyzed stages (grape, must, wine), and this sample had the highest amount of volatile acidity (2.11 g/L), exceeding the maximum acceptable limit for red wines of 1.2 g/L. A. pasteurianus was more common than A. aceti, both in musts and wines. Samples positive for AAB but containing low amounts of them in wine (Cq value > 35) did not have volatile acidity above the acceptable level. Samples that were wine-negative but must-positive for AAB had volatile acidity close to the acceptable limit. This study shows the utility of PCR diagnostics for predicting the risks of wine spoilage by AAB. Full article

The most frequent type of cancer, colorectal cancer (CRC), is widely recognized as the most common cause of death worldwide, due to the high invasive potential of cancer cells enabling metastasis. Cancer cells owe these properties to the epithelial–mesenchymal transition (EMT), which requires the overexpressed markers Snail and vimentin. Considering that natural products have been intensively investigated from an anticancer point of view, we aimed to investigate the effects of royal jelly, a natural bee product, on the invasiveness of the colorectal cancer cell line HCT-116 and the expression of these two proinvasive/EMT markers. Our study reports on the inhibited expression of Snail and vimentin in tested cells, due to which suppressed aforementioned potential was detected. Full article

Chefs often say, “You eat with your eyes first.” This means that, while taste, smell, and vision are distinct senses, visual stimuli generate expectations through learned associations, and these expectations exert cognitive top–down influences that can and sometimes do alter assessments of taste and flavour. This study investigates the intangible values associated with the visual assessment of high-end pastry cakes among individuals from diverse food cultures. Using word association, the study explored the emotions, sensations, and impressions evoked by the visual representation of five high-end pastry cakes. Thematic content analysis was conducted to interpret and group the evoked words into dimensions. Across all cultures, “Organoleptic properties” emerged as the most highly rated dimension, aligning with expectations for food product visual assessments. Full article

Bioactive compounds such as polyphenols are ubiquitous in many foods. However, their presence varies in structure, concentration, and action along food manufacturing and digestion. The simulated digestion assays allow for the estimation of variations in bioaccessibility and bioeffectiveness of polyphenols within foods. In this study, a polyphenol-enriched food model was used: sweet cookies with 10% defatted sesame flour (DSF). Polyphenolic extracts were obtained from DSF, a base cookie formulation and cookies enriched with DSF. In addition, extracts of potentially bioaccessible polyphenols from digested cookies in vitro were collected. The HepG2 liver cell line was incubated with all these mentioned extracts and then injured with H₂O₂. The following parameters were analyzed: intracellular oxidative state and viability by flow cytometry, antioxidant enzymes and glutathione content, and oxidation of proteins and lipids by spectrophotometry. The results show that DSF may be considered for functional incorporation in foods, since it may promote antioxidant response, providing preventive benefits and protective action in an oxidative damage context. This study also demonstrates that DSF actions on redox state vary depending on the food matrix and its degree of digestion. Cookies with DSF presented a pro-oxidant effect that could enhance the antioxidant response. Furthermore, after digestion, these cookies continue to show biological activity, evidencing the possibility of advantages from the consumption of these foods. These data show the need to improve the knowledge of the biological actions carried out by certain metabolites present in food and the impact of their digestion over their effective role in health.

Berry fruit seeds should be treated as a valuable waste product of the fruit industry. In the following study, oils from cranberry, black currant, red currant, strawberry and chokeberry seeds were extracted by conventional and pressurized liquid extraction. The quality of oils was assessed by determining oxidative stability (onset and maximum time of induction) with the use of pressure differential scanning calorimetry, fatty acids composition by gas chromatography and health indices, such as atherogenicity, thrombogenicity and hypocholesterolemic indexes. Additionally, health-promoting index was calculated. It was found that the fatty acid profile was not affected when pressurized liquid extraction was used. The major fatty acids in the studied oils were linoleic acid ranging from 36% for cranberry seed oil to 69% for chokeberry seed oil, followed by α-linolenoic acid in the case of cranberry, strawberry and red currant seed oils or by oleic acid for chokeberry and black currant seed oils. The oxidative stability of fats extracted with the use of pressurized solvent was significantly lower compared to oils obtained using the conventional extraction process, e.g., the maximum induction time for conventionally extracted chokeberry seed oil was 40.74 ± 0.66 min and 9.24 ± 0.57 min when pressurized liquid extraction was applied. The studied oils had low values of atherogenicity and thrombogenicity indexes, which, when combined with high values of hypocholesterolemic index, qualifies them as high nutritional quality oils. However, further studies regarding the process optimization are needed in order to obtain oils with improved quality, especially better oxidative stability. Full article

The aim of this research was to evaluate the physicochemical and textural properties of food hydrogels produced using pea protein and gellan gum. The obtained samples were analyzed in terms of their volumetric gelling index, microrheology, texture, physical stability, and color parameters. Most of the obtained samples formed a gel structure. In the case of microrheology parameters, by combining PP and GG, the solid–liquid balance was shifted towards more solid-like properties, which was also observed while analyzing the elasticity index (EI) and the textural properties of the obtained hydrogels. Additionally, a color difference between the obtained samples was noticed. Depending on the properties that the final food product must exhibit, a binary protein–polysaccharide hydrogel can be used as a matrix to contribute to that product’s physicochemical and textural properties.

The aims were: (a) to biomonitor vanadium (V) in wild edible mushrooms collected from urban/rural areas across Leicestershire (England); (b) to characterise the risk to humans caused by its content in topsoils. Thirty-four mushrooms were collected: twenty-two Agaricus bitorquis from a green area close to a busy traffic area; four Marasmius oreades from the NE; and eight Coprinus atramentarius from Bradgate Park, which is northwest of Leicester city. Moreover, 850 topsoil samples were collected and processed as composite samples (eighteen urban and eight rural), which were further processed in duplicate. The level of V was measured twice in each of the 52 composite samples and in the cleaned, dried and homogenised mushrooms by ICP-MS. Significant higher levels of V were found in C. atramentarius (0.856 (0.175–4.338)) than in the edible mushrooms collected in the urban areas (M. oreades, 0.305 (<LoD-0.852), and A. bitorquis, 0.078 (<LoD-0.187); the median and range are given in mg/kg dw). The health risk quotients calculated suggested a minimal risk to V if eaten. The presence of V in Leicestershire’s topsoils would also not represent a significant risk for the population.

Studies on the impact of colonic fermentation of plant sterol (PS)-enriched foods using dynamic in vitro models are limited. This study aimed to evaluate the effect of a 72-h dynamic in vitro digestion-colonic fermentation (using the simgi^® system) of PS-enriched rye bread on colonic microbial population and short-chain fatty acid (SCFA) and ammonium production. In all colon compartments (ascending colon (AC), transverse colon (TC), and descending colon (DC)) (72 vs. 0 h), a reduction in ammonium concentration (5.7- to 9.4-fold) and an increase in Staphylococcus spp. (1.4- to 2.1-fold), Lactobacillus spp. (1.5-fold), Bifidobacterium spp. (1.3- to 1.5-fold), and Enterococcus spp. (1.4- to 1.6-fold) were observed. In AC and TC, total SCFA decreased (4- and 1.3-fold, respectively), whereas it increased 1.4-fold in DC due to an increase in butyrate content from 4 to 45 mM. These results suggest that PS-enriched rye bread favors the growth of beneficial microbial species and the production of butyrate, a fuel source for enterocytes, thus promoting health benefits.

Inulin is a molecule, namely, a functional dietary fiber from non-digestible carbohydrates, and is generally utilized in pasta production at concentrations or replacement ratios of 0.5–20%. As highlighted in this study, the optimum cooking time and swelling index of inulin-added pasta ranged between 5.0–14.0 min and 1.5–2.6 g/g, respectively. The protein content generally decreased, whereas dietary fiber increased with the addition of inulin to pasta formulations. Therefore, lower starch hydrolysis and glycemic index could be achieved with inulin enrichment in pasta. However, more in vitro and in vivo digestion studies are still needed to evaluate its beneficial effects on human health. Full article

Five varieties of industrial hemp (Cannabis sativa L.; Futura 75, Futura 83, Felina 32, Earlina 08 FC and Henola) were planted to produce grain and then to study their potential as an alternative source of nutritional compounds due to their fat, carbohydrate and protein content. The lipid fraction can account for 35% of the total composition of hemp seeds; therefore, the aim of this study was to determine their fat content, focusing mainly on the characterisation of the fatty acid profile of the different varieties of hemp seeds through gas chromatography with a flame ionisation detector for possible use of the whole grains or the oil extracted from them. The fat content of the seeds ranged between 23 and 31% of the total composition, with Earlina 08 FC significantly (p < 0.05) being the richest in fat content. We also found that 87% of the total fatty acids were unsaturated, being polyunsaturated acids the main group and linoleic acid the most abundant fatty acid. In addition, linoleic acid acts as a precursor of biologically active molecules involved in many physiological processes. Thus, hemp seeds may be considered a valuable source of healthy fatty acids to include in plant-based food formulation, regarding that further studies are being conducted to characterise other nutritional components.

The purpose of this study was to determine the extraction of hydrolysate protein from waste materials (rice grain and rice beverages) in order to increase the value of domestic raw materials. The goal was to create protein beverage products containing rice protein hydrolysates that are customized to the needs of athletes for post-workout muscle restoration. Carbohydrates were extracted from rice paste using an amylase enzyme, followed by protein extraction using the Protease G6 enzyme. The E/S SL ratio, temperature, and time were investigated, with the extraction taking place at a pH of 7.0. The Central Composite Design approach was used in the experimental design to change the extraction conditions. The protein concentration and the concentration levels were determined. The concentration data were then submitted to 95 percent confidence level Analysis of Variance (ANOVA) to find significant differences. To visualize the relationship between protein concentration and the interaction between the E/S SL ratio, temperature, and extraction duration, a contour plot was generated. The results showed that increasing enzyme proportions and temperatures between 50 and 60 degrees Celsius boosted protein concentration. Lower E/S SL ratios and longer extraction times enhanced protein concentration. An E/S, SL ratio of 5%, a temperature of 52 degrees Celsius, and an extraction time of 180 min were shown to be ideal conditions for extracting protein from rice grains utilizing the Protease G6 enzyme. The final protein content was 3.14 g/100 mL. These findings suggested that Protease G6 can be a viable alternative for developing rice protein beverages for athletes and health-conscious individuals.

Platelet function is closely linked to cardiovascular health. Functional foods such as yogurt and oily fish are enriched in bioactive polar lipids, which can reduce platelet activation and the incidence of cardiovascular disease. This pilot project investigated the effect of fermented ovine yogurt on platelet sensitivity in human plasma. Overall, in vitro studies established that yogurt lipid fractions inhibit platelet aggregation. Preliminary dietary intervention data indicate that yogurt intake may reduce platelet activation against the thrombin pathway, compared to the placebo. However, larger studies are required to robustly establish the effect of yogurt intake on platelet sensitivity, following this interim analysis. Full article

Diabetes is a metabolic disease of global concern, causing death due to triggered oxidative and inflammatory complications. Alpha-glucosidase has become a popular drug target for managing diabetes. This study, therefore, investigated the potential of Curcuma longa (Tumeric) rhizome methanolic extract (MECL) to inhibit alpha-glucosidase and screened its phytochemical library through molecular biology docking for potential new drug candidates. Quantitative phytochemical analysis of MECL showed that the plant extract was abundant with phenols (790.32 ± 129.20 mg/100 g), alkaloids (494.99 ± 1.27 mg/100 g), flavonoids (171.08 ± 0.04 mg/100 g), and terpenoids (131.99 ± 6.59 mg/100 g). Moreover, in vitro inhibitory studies showed a dose-dependent increase in the inhibition of alpha-glucosidase by MECL, and the maximum inhibition (37.01%) was observed at 30 µg/mL, possibly a better inhibition with increased concentration. Further scrutiny was performed using molecular docking to screen for Turmeric phytochemicals (retrieved from PubChem) with alpha-glucosidase (PDB ID: 3W37) inhibitory potentials. Based on their binding affinity, the top three compounds [Guaiacol (−7.422), Eriodictyol (−5.266), and p-Tolyl-MethylCarbinol (−3.939)] were analyzed for their intermolecular interactions in the binding pocket of alpha-glucosidase and ADMET properties; and compared to the standard drug, acarbose (−9.522). Interestingly, strong and weak interactions, such as hydrogen bonding, pi-pi stacking, and charged and hydrophobic interactions, were observed with Guaiacol in the binding pocket of alpha-glucosidase. Although acarbose had a better docking score, Guaiacol showed better ADMET (including physicochemical, drug-likeness, and pharmacokinetic) properties. Future studies could evaluate those potential anti-diabetes drug candidates against other targets and analyze them through in vivo experiments. Full article

Noni (Morinda citrifolia L.) is utilized for wellness drinks, puree, and nutraceuticals, while its seeds are a source of vegetable oil. However, misconceptions persist due to limited scientific research in Sri Lanka. This study evaluated the cytotoxic effects of hydro-methanolic extracts from fresh and dried noni fruits, pasteurized juice, and seeds on normal (BHK) and cancer (Hep2) cells using the MTT assay. The results indicated dose-dependent toxicity on cancer cells, while normal cells were less affected. Processing methods influenced cytotoxicity, with dried seeds showing the least toxicity. These findings suggest the potential of noni extracts as cytotoxic agents against cancer, influenced by the processing conditions. Further research is needed to identify the specific bioactive compounds and their mechanisms. Full article

Macroalgae, or seaweed, has a long history of use in human diets, especially in Eastern nations. However, the present interest in these species is driven by their remarkable bioactive and nutritional qualities and their significant availability and underutilization, making them incredibly alluring to people following alternative dietary patterns like vegetarianism and veganism. Sargassum muticum, also known as Japanese wireweed or Asian seaweed, is considered edible and has been consumed in some cultures, popular as a soup ingredient in Korea. This brown macroalgae found in marine environments has been introduced in various regions outside its native range, including Europe and North America. Moreover, this species could be helpful in feeding animals or as soil fertilizer. In this study, the nutritional properties of this marine macroalga were investigated. Nutritional parameters such as protein, sugar, and fiber content were analyzed using classical techniques. In addition, its proximate composition was also determined in terms of moisture, fixed and volatile carbon, and ash content using thermogravimetry, and their major minerals, including calcium, potassium, and magnesium, was determined using the ICP-OS technique. In terms of its mineral content, it was found to have a high mineral content (21% of ash), which consisted mainly of calcium (9 g/kg dw), potassium (77 g/kg dw), and magnesium (12 g/kg dw). In addition, this study determined the presence of iodine using ICP-MS, and 106 mg/kg dw of this essential element was quantified in these algae. The results of this study highlighted the potential nutritional benefits of the tested marine algae. Their composition revealed significant concentrations of vital elements, making them highly advantageous for human/animal dietary requirements with possible health benefits. Full article

The current market requires new fish-based products. In this context, the use of focus groups is a qualitative technique that enables the generation of ideas for the development of new products. The aim of this study is to create a list of ideas for products based on two species from aquaculture: sea bream and prawn. To achieve this, two sessions were conducted involving 20 individuals from diverse backgrounds. The sessions included consumer surveys, exploration of new products, brainstorming, and categorization of ideas into product categories. As a result, the frequencies of idea mentions were obtained, with the ‘fresh products’ category being the most frequently mentioned for both species. Furthermore, associations between product categories and participant profiles were established using correspondence analysis (CA). In conclusion, for sea bream, consumers showed a preference for fresh product ideas. Conversely, for prawns, canned and dehydrated products were consistently suggested across all participant profiles. This study lays the foundation for innovative aquaculture product development.

In this paper, a study to determine the acoustic properties of Chihuahua, Manchego, and panela cheeses is carried out by applying acoustic spectroscopy in the ultrasound spectrum. The products were purchased at a local store in the capital city of Chihuahua. The echoscope block of the GAMPT^® acoustic tomograph with acoustic sensor at 2 MHz was used to measure the acoustic phase velocity (m/s), which depended on the thickness, with a quasiregular ambient temperature of 16 °C. The acoustic tomograph used transmission with normal incidence. Measurements were performed in triplicate. The volumetric density and acoustic impedance of the cheeses, as well as the rheological properties, were determined through an indirect method. The results show that the acoustic phase velocities of the Chihuahua, Manchego and panela cheeses were APV_Chi ≈ 1221.47 m/s, APV_man ≈ 1436.05 m/s, and APV_pan ≈ 1142.28 m/s, respectively. The volumetric densities of the Chihuahua, Manchego, and panela cheeses were ρ_Chi ≈ 1.16 gr/cm³, ρ_man ≈ 1.11 gr/cm³, and ρ_pan ≈ 1.70 gr/cm³ to 12.1 °C, respectively. Full article

This study aimed to determine storage conditions for microparticles containing habanero pepper extracts with maltodextrin (MD) and a 95:5 w/w mixture with precipitated silica (MDSP) as wall materials. State diagrams (SD) using water adsorption isotherms and glass transition temperatures were created. Monolayer values were 6.17 g (MD) and 6.76 g (MDSP) of water/100 g d.s. Critical water activity values (a_wC) were 0.49 for MD and 0.41 for MDSP. When stored at a_w > a_wC, both samples underwent physical transformations, with significant color changes (ΔE > 8). Conversely, storage below a_wC resulted in minimal changes (ΔE < 4), consistent with the SD. Full article

Goat milk and cheese are popular dairy products known for their nutritional value and distinct flavors. The presence of bioactive compounds such as carotenoids and volatile compounds in these products contributes to their sensory characteristics and potential health benefits. This study aims to compare the content of bioactive compounds in goat milk and the cheese that was produced thereof. High Performance Liquid Chromatography (HPLC) equipped with diode array detector (DAD) was used for the quantification of beta carotene and lutein content. The lutein content in milk samples displayed higher values ranging between 0.11 and 0.25 mg/100 g per sample compared to cheese samples. Beta Carotene was not detected in either of the matrices. For the identification of volatile compounds, Solid Phase Microextraction/Gas Chromatography-Mass Spectrometry (SPME/GCMS) were used. The volatile compounds detected were classified into terpenes, ketones, aldehydes, acids and esters. Esters constituted the most abundant group of compounds in all samples. The simultaneous analysis of these compounds provides valuable insights into the nutritional composition, flavor profiles, and potential health benefits of goat cheese and milk. At last, the major elements comparison of milk and cheese products, including Calcium (Ca), Phosphorus (P), Potassium (K), Sodium (Na), Magnesium (Mg), Chlorine (Cl) and Sulfur (S), were quantitatively measured across all samples using a wavelength dispersive X-ray Fluorescence (WD-XRF) to establish their elemental profiles. Milk samples exhibited higher concentrations of Potassium. Conversely, cheese products displayed elevated levels on all the other elements. Full article

In recent years, the valorization of food by-products has attracted increased interest in the scientific community for ecological and economic reasons. Opuntia ficus-indica (OFI) peels are the primary by-products of prickly pears. Several studies claim that the beneficial bioactive compounds are concentrated in the fruit’s peel. Therefore, the present investigation aimed to study the immature OFI peel as a natural antioxidant in mayonnaise and its use as a natural treatment against coccidiosis, which is the main disease of broiler chickens. The findings confirmed that OFI peels are a source of phenolic compounds, including total phenolic compounds, flavonoids, tannins, and carotenoids (21.01 ± 0.33, 1.12 ± 0.28, 10.25 ± 0.10 mg equivalent standard/g, and 5.62 ± 0.53 mg β-carotene equivalent/100 g, respectively), having strong antioxidant activities over 87 percent (DPPH radical, iron chelation power, β-carotene bleaching). Using the rancimat test, OFI extract improves the mayonnaise’s stability for 2.5 h. Immature OFI peel extracts recorded a notable destruction rate of Eimeria oocysts. The current study promoted the use of immature OFI peel extracts as a natural food additive and as an antiparasitic treatment substitute. Full article

Walnuts (Juglans regia) are characterized by a high fat content of approximately 73%. The oil contained in the nuts is rich in unsaturated fatty acids, including monounsaturated oleic acid and polyunsaturated fatty acids, both of the n-3 and n-6 family. One important thermal process for nuts is roasting, which significantly increases their palatability. Technically, roasting is a drying process at high temperatures. The purpose of roasting is to reveal new flavor and aroma properties of the raw material. The aim of the current study was to determine and compare the fatty acid composition and oxidative and hydrolytic stability of oils extracted from both roasted and raw walnuts. Full article

Snacking outside of main meals is common and often a dietary requirement, especially for children and toddlers. This habit has both social and educative dimensions, as it has become an established moment in people’s daily routines. We conducted an easy online survey involving students and their families from schools in the Abruzzo region, Italy. The aim of the survey was to understand the participants’ habits, food choices, and meal composition during snack time. Additionally, we inquired about their general health state. Our interest lies in knowing more about this population, with sufficient data to observe whether habits and food choices may be accountable for exposure to biogenic amines (BAs). BAs are unavoidable natural compounds that come from the catabolism of amino acids in tissues. They are possibly involved in reactions such as allergic-like manifestations, abdominal pain, and more severe symptoms depending on individual sensitivity. The action of BAs can be augmented by the intake of foods, mainly fermented products, which are common in everyday diets. We collected 300 responses from students ranging from 11 to 18 years old. The most popular foods eaten were sweets (pastries, cakes) and sweet bakery products, followed by yogurt-based and milk-based products (30% and 23%, respectively). Most students (58%) reported having a snack moment daily. The population was generally in good health, but some reported experiencing light discomfort after snacking, such as transient gastrointestinal pain, headache, and dermatological symptoms (8.7%, 2%, and 0.7% of the total, respectively). All this information may be linked and added to the knowledge about BA content in foods and their potential impact on health. Full article

The composition and ratio of volatile compounds in soy sauce have a major impact on its organoleptic properties. Considering the important influence of long-term (3 months) moromi fermentation on the aroma formation of soy sauces from different materials (soybean, rice, black bean, wheat, wheat flour and mungbean), the volatile compounds of 24 samples in total, taken from three different stages of moromi fermentation, were analyzed via solid phase microextraction coupled with gas chromatography–mass spectrometry (SPME–GC–MS). The results show a total of 77 volatile compounds, including acids (4), alcohols (14), phenols (6), aldehydes (12), esters (26), ketones (5), furan(one)s (5) and pyrazines (5), and the majority of the compounds were common. Among all samples, the highest number of volatile compounds (5528.58 ± 1308 µg/L) was detected in the moromi made from the combination of soybean, black bean and wheat flour on the first month of fermentation, and the sample that had the lowest number of volatile compounds (63.25 ± 1.70 µg/L) was detected in the moromi sample made from the combination of soybean and wheat flour on day 0. During the three months of moromi fermentation, the relative contents of acids, alcohols, phenols, aldehydes, esters, ketones, furan(one)s and pyrazines changed gradually. Finally, the total presence of volatile compounds identified in the 24 samples increased from day 0 to 1 month and from month to month perfectly. Full article

This study aims to explore the relationship between food quality and mental health by comprehensively analyzing existing research. A systematic review was conducted to identify relevant studies published between 2010 and 2022. The selected studies encompassed various populations, including adults, adolescents, and elderly individuals, and examined the impact of food quality on mental health outcomes such as depression, anxiety, and cognitive function. The findings of the analysis revealed a significant association between food quality and mental health. Several studies indicated that a diet rich in fruits, vegetables, whole grains, and lean proteins was positively correlated with better mental health outcomes. Conversely, a diet high in processed foods, sugar, and saturated fats was associated with an increased risk of mental health disorders. Furthermore, the analysis highlighted the role of specific nutrients in mental health. Omega-3 fatty acids, found in fatty fish and nuts, were consistently linked to improved mood and cognitive function. Additionally, the consumption of antioxidants, vitamins, and minerals from fruits and vegetables showed positive effects on mental well-being. However, it is important to note that the relationship between food quality and mental health is complex and influenced by various factors such as socioeconomic status, cultural background, and individual differences. Future research should consider these factors to obtain a more comprehensive understanding of the topic. In conclusion, this study provides evidence supporting the relationship between food quality and mental health. Adopting a healthy diet rich in nutrient-dense foods may have a positive impact on mental well-being. Further research is needed to explore the underlying mechanisms and develop targeted interventions to improve mental health outcomes through dietary interventions. Full article

The production of high-quality rum requires a carefully controlled fermentation process, which is determined by the physicochemical and nutritional properties of the molasses used as a substrate. The flavor, aroma, and alcohol content of the final product are heavily influenced by the composition of molasses. This paper presents the results of an extensive analysis of molasses, a byproduct of sugar production that has various applications in food and feed industries. The physicochemical properties and nutritional composition of molasses were investigated using a range of analytical techniques including Brix, moisture content, pH, total ash content, total dissolved solids, crude protein, sugar content, total nitrogen, free amino acids, amino acids, mineral content, vitamins, and organic acids. This study analyzed molasses samples obtained from three painted concrete constructed storage wells at the Bundaberg Distilling Company. The results indicated that the molasses samples possessed a substantial sugar concentration, with sucrose being the most abundant, ranging from 35.02 to 35.27% w/w. These findings support the traditional use of molasses in rum fermentation and use as an alternative feedstock for the synthesis of various value-added chemicals. The pH of the molasses was slightly acidic, and the total ash content was relatively high, ranging from 8.76 to 13.55% w/w, indicating the presence of mineral salts. Mineral content varied among the samples, but all three contained significant levels of sodium, phosphorus, potassium, calcium, and magnesium. All the samples contained essential amino acids and vitamins, but their levels varied. The molasses also contained varying levels of different organic acids, including acetic, propanoic, aconitic, formic, valeric, lactic, citric, and malic acids. The analysis revealed significant differences in ash content, nitrogen compounds, and minerals between storage wells, indicating inherent variability between batches. However, key fermentable sugars did not significantly differ between samples, and blending or standardization is recommended to minimize batch-to-batch variation prior to fermentation. This study provides valuable information on the composition and quality of molasses, which can be used to optimize its utilization in rum fermentation and various other applications. Full article

The present study concentrated on the quality assessment of spent coffee grounds (SCG) blends collected after the brewing process in local commercial cafeterias. To obtain SCG extract and oil, the ultrasound-assisted extraction with 60% hydroethanolic mixture and the conventional solid–liquid extraction with hexane were carried out, respectively. The quality of the SCG blend was assessed by performance of the ensuing analysis: total polyphenols content (TPC), antioxidant activity by using ABTS and FRAP methods, browning index (BI), caffeine and chlorogenic acids contents by using high-performance liquid chromatography as well as oxidative induction time (OIT) by using the pressure differential scanning calorimetry and fatty acids profile by using the gas chromatography. The SCG extract was characterized by a high TPC (33.79 mg GAE/g SCG), BI (0.2), caffeine (5.25 mg/g SCG), and chlorogenic acids (7.52 mg/g SCG) contents. In addition, ABTS and FRAP methods revealed the high antioxidant activity of SCG extract. The OIT of SCG oil reached 43.8 min. The SCG oil mainly contained palmitic acid (37.18%) and linoleic acid (39.69%). Overall, SCG can be regarded as a coffee by-product abundant in various chemical compounds with biological and antioxidant activity, but it is necessary to examine the opportunity for the implementation of SCG in particular forms as a new constituent of functional foodstuffs.

The consumption of food supplements in Latin America represents 7% of the world’s consumption, as reported by the Latin American Alliance of Responsible Nutrition (ALANUR) in 2021. Developing high-quality Andean-grain supplements could be interesting for enhancing the country’s food security. A supplement has been developed that contains high-quality protein and carbohydrates sourced from a blend of precooked quinoa and amaranth flours. Additionally, it includes omega-3 and omega-6 fatty acids derived from microencapsulated sacha inchi and chia oils, along with vitamins and minerals. The process for obtaining the precooked flours involved cooking at 75 °C for 12 min, followed by drying in a tray dryer at 70 °C for 8–9 h, grinding in a disk mill, and sieving to achieve a particle size of 150 µm. Pasta tests were conducted using RVA and DSC to check their gelatinization. The supplement’s composition adheres to the mandatory nutrient requirements specified by the Ecuadorian standard NTE INEN1334-2, 2011. Moreover, the supplement satisfies the sensory criteria related to taste and consistency. To evaluate the impact of the processing on the nutrients’ attributes, assessing their bioaccessibility becomes significant. To accomplish this, the static in vitro digestion method was employed, both before and after the digestion process. The digestion protocol involves the following steps: an oral phase with amylase, a gastric phase with pepsin, and an intestinal phase with pancreatin. The resulting digest was subsequently centrifuged and filtered. The apparatus utilized consisted of a reactor equipped with precise controls for temperature, pH, and agitation. The in vitro digestibility percent for the supplement shake was determined to be 96.7% (IVD). Essential amino acids were quantified through HPLC analysis with a fluorescence detector. As a result, lysine and histidine exhibited the highest bioaccessibility values of 97% and 79%, respectively, while methionine had the lowest value of 32%. The remaining amino acids showed intermediate values. Full article

Kiwi fruit is a member of the “Actinidiaceae” family, with over 76 species and cultivars with a wide range of sensory attributes. The kiwi fruit is one of the most popular fruits in the world, and it is high in nutrients such as vitamins, phytochemicals, and minerals. Candies have a low nutritional value because of their principal constituents, which include gelling agents and sugar. In comparison to conventional candy, the goal of this project is to make a natural and healthy dehydrated candy utilizing fresh kiwi fruit. The fruits were obtained from the local market of Faisalabad. Two types of dehydrated kiwi candies were prepared (T1: peeled; T2: unpeeled). In the last step, the sweets were kept in a dehydrator at 50 degrees Celsius for 24 h. Candy’s physiochemical, color measurements, and sensory characteristics were assessed. In all physio-chemical and sensory evaluations, the unpeeled candy produced the best results. The unpeeled candy’s TSS value, titratable acidity, pH, and vitamin C content was 77.9°, 0.36%, 4.5, and 37 mg, respectively. Unpeeled candy has a slightly darker color as compared to peeled candy, and color values L*, a*, and b* were 43.89, 0.43, and 11.34, respectively. Candy’s sensory study employing a nine-point hedonic scale reveals the highest consumer acceptability in terms of flavor, scent, mouthfeel, and texture. Full article

In the last decade, the use of natural antimicrobial agents, like polyphenolic extracts in postharvest applications, has gained attention. However, a significant challenge lies ahead. Demonstrating these agents’ commercial-scale production feasibility, practical applications, and economic viability compared to traditional agrochemicals is crucial. This review focuses on the achievements and obstacles in using polyphenolic extracts from Mexican crops as natural antimicrobial agents against postharvest phytopathogens and foodborne microorganisms. A comprehensive knowledge of the molecular mechanisms in vitro and in vivo, as well as plant systems, is essential for better results. Toxicity assessments and an evaluation of the impact on fruit quality are needed. Incorporating coating and encapsulation techniques can enhance the effectiveness of extracts. An integrated approach is needed for efficient, cost-effective control throughout the preharvest, harvest, and postharvest phases. Successful commercialization depends on the cost–benefit analysis, infrastructure, raw materials, local needs, and technical facilities, among other factors. Additionally, incorporating strategies related to circular economy can improve plant residue utilization and enhance technological and marketing approaches. Full article

Oil cakes are pomace that is a by-product of pressing oil from oilseeds. Due to the content of bioactive ingredients, there is more and more talk about their valorization through use in human and animal nutrition as well as microbiological processes aimed at the biosynthesis of biosurfactants, enzymes and fragrance compounds. The aim of this research was a qualitative assessment of selected oil cakes (linseed, rapeseed, hemp, safflower and camelina oil cakes) in the context of their potential use in microbiological cultures aimed at the biosynthesis of green note aroma compounds. The scope of the research included the analysis of the fatty acid composition of the lipid fraction of oil cakes as well as the determination of lipoxygenase activity and the polyphenol content in the extracts of these raw materials. Chromatographic analysis of the lipid fraction showed that hemp and safflower cakes had the highest content of polyunsaturated fatty acids. PUFAs constitute 67.18 ± 2.2% and 73.72 ± 1.8% in their extracts, respectively. Hemp cake extracts were also characterized by the highest lipoxygenase activity—76.4–1.2 U/mL with a low content of phenolic compounds at the level of 0.116 ± 0.005 mg GAE/mL of extract.

This paper compared the biometric and physicochemical characteristics, mineral elements, nutrients, and bioactive compounds of pitaya with white and red pulp. The nutrients and bioactive compounds were analyzed by HPLC. The total phenolic compounds and the antioxidant capacity were determined by spectrophotometry. Pitaya red pulp showed higher vitamin E (140.76 Gg µg·100 g⁻¹), antioxidant capacity (36.41 AAT%), eriodictyol (178.75 µg·100 g⁻¹), and anthocyanins. The α-carotene showed higher expression in the white pulp (110.21 µg·100 g⁻¹). The total phenolic content was similar in both fruits. Pitaya consumption should be encouraged due to the presence of nutrients and bioactive compounds relevant to our basic nutrition. Full article

This study’s objectives were to evaluate the possibility of S. aureus contamination in bottled drinking water and to determine the elements that affect the level of S. aureus in raw water. In two drinking water treatment facilities, samples of raw water, soft water, reverse osmosis (R.O.) water, and finished water were collected at various stages. In addition, raw water samples and risk indicators like pH, temperature, and residual chlorine were gathered at the packaging facility during the washing process. For Factory A (small scale), the pH values for the raw water, soft water, R.O. water, and finished water samples were 7.17, 7.24, 6.69, and 5.92, respectively. For Factory B (medium scale), the pH values were 7.9, 7.44, 6.97, and 6.8. All water samples from Factory A (2 CFU/mL) and Factory B (1 CFU/mL) had S. aureus concentrations that were within the acceptable range for human consumption. All water samples from Factory A (2–26 CFU/mL) and Factory B (11–316 CFU/mL) contained total coliforms as well. Our study revealed that S. aureus contamination in water is mostly caused by pH and processing times. To prevent pathogen contamination in bottled drinking water, it is recommended that raw and finished water be kept at a pH level between 6.5 and 7.5. Full article

In the present work, the effect of the Flash Vacuum Expansion (FVE) process on the recovery of total phenolic content (TPC) from entire coffee peel was evaluated. The resulting extracts were microencapsulated by spray drying using maltodextrin (MD10) and arabic gum (GA). The FVE increased TPC by 20.97% in the ethanolic extracts. The use of MD10 allowed obtention of smaller, less hygroscopic particles, with better color and flow properties as well as a higher concentration of TPC. Both powders were considered microbiologically stable based on humidity and water activity. Full article

Fruits are an essential part of a healthy lifestyle, providing the body with the necessary nutrients and helping to prevent illness. Recognizing the importance of fruits, our study aimed to create a unique and nutritious mixed fruit jam using the delightful combination of kiwi and cucumber. We chose kiwi and cucumber for this experiment due to their exceptional nutritional value. Kiwi is rich in vitamin C, vitamin K, and dietary fiber, while cucumber is hydrating and contains vitamins A, C, and K. Combining these two fruits not only adds a refreshing flavor but also enhances the nutritional profile of jam. In our experiment, we tested different ratios of kiwi and cucumber, including 100% kiwi (control), 50% kiwi and 50% cucumber, 70% kiwi and 30% cucumber, and 30% kiwi and 70% cucumber. To improve the texture and preservation of the jam, we added commercial pectin, sodium benzoate, and citric acid. Through comprehensive analysis, we found that the jam made with a 50%:50% kiwi ratio (T₁) stood out regarding its physicochemical properties. It had higher levels of titratable acidity, total soluble solids, moisture, pH, and ascorbic acid while having a lower proportion of total sugar. These attributes contribute to a well-rounded nutritional profile, making it an excellent choice for individuals seeking a healthy option. To ensure the jam’s sensory appeal, we conducted sensory assessments evaluating its taste, scent, texture, and overall acceptance. The T₁ jam received the highest scores in all sensory categories, indicating that it was the most preferred option among the participants. Its vibrant green color, with L*, a*, and b* values of 32.41, −2.29, and 9.51, respectively, adds to the overall sensory experience and entices consumers to indulge in its goodness. In conclusion, our study highlights the nutritional excellence and sensory delight of the kiwi-based jam, particularly the T₁ variant. By combining the goodness of kiwi and cucumber, we have created a jam that not only satisfies taste buds but also nourishes the body. It is an excellent choice for individuals of all ages looking for a healthy and enjoyable spread. So spread this fruity goodness on your toast and savor the benefits. Full article

The incorporation of alternative flours in the formulation of gluten-free (GF) baked goods has the potential to improve their nutritional and technological characteristics. Within this context, the addition of novel flours from the grinding of seed-endocarp (ES) and the exocarp/mesocarp (EM) of Neltuma affinis fruit was studied in the design and formulation of GF bread. The aim of this study was to evaluate the effects of different levels of ES, EM and water hydration (WH) on the alveolar structure, pH and colour of GF bread. A Box–Behnken response surface design was used. EM and ES were found to have a negative effect on pH. The alveolar structure of the bread was influenced by the level of hydration, with larger alveoli being observed in the bread crumb at higher levels of hydration and greater density at lower levels. The three factors studied showed a positive influence on the a* coordinate of the colour of the crumb. In conclusion, the incorporation of alternative flours from N. affinis could be a valuable approach to improve the nutritional profile and sustainability of an underappreciated species. Full article

The objective of this study was to investigate the optimal ratio of a mixture of Thai riceberry rice flour, Job’s tears flour, and black sesame seeds in developing a healthy cereal granola bar. Based on the experimental mixture design of 10 formulations of a granola bar, the mixture ratio of riceberry rice flour, Job’s tears flour, and black sesame seeds affected the quality of the cereal granola bar in terms of its physicochemical and sensory properties, and the differences were statistically significant (p ≤ 0.05). The main ingredients of the granola bar formulation that was well accepted were riceberry rice flour (5%), Job’s tears flour (35%), and black sesame seeds (5%). The peak viscosity of riceberry rice flour and Job’s tears flour, as measured by the Rapid Visco Analyzer (RVA), was 943.67 ± 49.60 cP and 1329.00 ± 10.71 cP, respectively. This product showed the highest overall liking score of 7.27 ± 0.64 with a water activity of 0.53 and a moisture content of 11.54%. These results suggest that the prepared local cereal granola bar can be a promising food product with nutritional value and antioxidant content. The addition of Job’s tears flour and riceberry rice flour improved the texture of the granola bars. Full article

The chestnut industry generates large quantities of by-products, including the chestnut shell, which is a source of phenolic compounds. In this study, the MIC (minimum inhibitory concentration) of chestnut shell extract was determined using the disk diffusion method. The chestnut shell was freeze-dried and milled. The extract was obtained using an ultrasound-assisted technique using water 70%: ethanol 30% (v/v) and subsequently lyophilized. Muller–Hinton plates were inoculated with ~10⁵ CFU/mL of microorganisms. Sterile paper discs (6 mm) were placed on the inoculated culture medium and impregnated with 10 µL of each extract. Seven concentrations of extract between 0.3% and 2.1% were tested. The plates were incubated for 24 h at 37 °C. The antibacterial efficacy of the extracts was indicated by a halo formed around the paper disk. This work was carried out in triplicate. Halos were found at 1.5%, 1.8%, and 2.1% on Listeria monocytogenes ATCC 7973 (8.32 ± 0.06 mm for 2.1%), Enterococcus faecalis 19433 (8.94 ± 0.41 mm for 2.1%), and Staphylococcus aureus ATCC (10.26 ± 0.19 mm at 2.1%). For the remaining microorganisms, no halos were observed. The tested extract showed antimicrobial activity, demonstrating its potential for the control of pathogens in the food industry.

Gluten-free baked goods (GFBGs) are based mainly on refined flours and starches, being characterized by a poor nutritional profile. The use of alternative flours rich in protein and dietary fibre, and with a good sensorial profile, in the formulation of GFBGs could improve either nutritional or sensorial properties. The objective of the study was to evaluate the global differences/similarities and overall acceptability of gluten-free breads (GFBs) formulated with alternative flours among regular consumers and those with gluten-related disorders. The results showed four well-differentiated groups of GFBs with descriptors related to texture, odour, flavour, colour, and crumb, and most of the samples received a punctuation in a range of 5.9–7.3 in a 9-point hedonic scale. The identification of descriptors in GFBs formulated with flours with a good nutritional profile could be a useful tool in the design of baked goods for the food industry. Full article

β-casomorphin 7 (BCM7) is a bioactive peptide that is released during the digestion of the β-casein (in particular, the A1 variant) present in cow’s milk. BCM7 has been linked to several health concerns such as gastrointestinal disorders. Milk processing alters the composition of milk, which in turn may affect its digestion, thus impacting the amount of BCM7 that is released. This study aimed to understand the impact of microfiltration on BCM7 release after the in vitro digestion (mimicking in vivo digestion) of semi-skimmed filtered milk compared to that of pasteurized milk and pasteurized Jersey milk (which does not contain A1 β-casein, the main source of BCM7). LC/MS was used to quantify BCM7. The results indicated that the β-casein variants present in milk, rather than the milk treatments themselves, are the key factors for the release of BCM7. Similar BCM7 levels were found in the filtered and pasteurized milk samples, whereas the Jersey milk released just half the amount. Full article
