Mead is described as a traditional alcoholic drink produced by fermentation from a solution of honey and water. It has been produced as a refreshing drink. However, in the past, it was more expensive than wine, which led to a decrease in demand. Due to the simple method of production, the mead industry is growing again. The quality and physicochemical properties of mead depend on the type of honey used. The goal of this study is to produce mead from two kinds of honey of different floral origins, chestnut and sunflower, in order to determine the differences using sensory and physicochemical analyses. The fermentation process was monitored until the extract values were consecutively the same. The results obtained in this research indicate that chestnut honey mead took a longer time to ferment, 2 months, while sunflower honey mead took 1.5 months to ferment. The alcohol content in chestnut honey mead was 7.2% v/v, and sunflower honey mead contained 8.6% v/v. Sensory-wise, the chestnut mead was more acceptable to consumers due to a more pronounced color and thus received a one-point higher score (15) than sunflower honey mead (14). Full article

The Tempranillo grape variety is the most widely cultivated red grape cultivar in Spain. However, it has been observed that this variety may not always exhibit the optimal colour properties in warm climates such as Andalusia (southern Spain). Several strategies have been proposed to enhance productivity and resilience to stress or improve the quality of both grapes and wines. The foliar application of agricultural plant extracts has been identified as a highly effective method of promoting the synthesis of secondary metabolites in the grapevine. The objective of the current research was to analyse the incidence of foliar application of different extracts from winemaking by-products (grape stems: GS, grape pomaces: GP and wine lees: WL) on Tempranillo grapevine leaves, studying the impact on the quality of the resulting wines. The oenological and colour characteristics of the wines were assessed to evaluate the impact of these extracts on wines during the winemaking process. The detailed composition of the wines revealed that GS and WL extracts led to significant differences in wine colour properties. Wines derived from grapes treated with both extracts exhibited heightened colour intensity, accompanied by discernible alterations in CIELab coordinates, with lower L* and higher a* and C*ab values in comparison to CT. These results are encouraging, and the foliar application of GS extracts at veraison appears to be a feasible alternative to enhance the colour of wines from red grape cultivars with colour difficulties in warm climates.

While providing considerable societal and economic benefits, plastic packaging leads to global pollution and poses health risks. Plastic additives like alkylphenols (APs) can interfere with endocrine functions even at low concentrations. Therefore, developing and validating analytical methods for their routine dosage in foods is paramount. The present work validated a chromatographic method to quantify alkylphenols (4-tert-octylphenol, 4-n-octylphenol mono-ethoxylate, 4-n-octylphenol, and 4-n-nonylphenol) in milk. The analytical method uses Chem Elut S a rapid supported liquid extraction (SLE) cartridges to eliminate the matrix effect, and reverse phase chromatography linked to a Diode Array Detector (DAD) to dosage the alkylphenols. The method was validated using the strategy of accuracy profiling, a decision-making instrument that calculates the method’s total error, encompassing bias and standard deviation. The reliability of the test was defined by the lack at the retention times of the APs of interfering peaks, the close linear relationship between the independent and the dependent variables in the regression model, the excellent precision at each concentration level for intra-day and inter-day measurements, and the errors of the procedure (systematic and random) estimated within the pre-established acceptability limits (±10%). The minimal environmental impact and ease of execution suggest its use in routine analyses. Full article

Pathogenic bacteria surviving acidic conditions in foods pose a persistent public health risk, with acid adaptation potentially enhancing their virulence in low-pH environments like fruit juices. In this study, we hypothesized that foodborne bacteria exhibit enhanced survival and pathogenic potential in fruit juice after undergoing prior acid adaptation. Thus, our aim was to investigate the pathogenic potential and survival of acid-adapted Salmonella Enteritidis and Escherichia coli O157:H7 in orange juice. Cells were acid-adapted by cultivation in a glucose-rich medium, resulting in an increase in bacterial populations from 3.0–3.1 to 8.7–9.0 log₁₀ CFU/mL, compared to non-acid-adapted controls. After 2 days at the common temperature storage of the fruit juices (4 °C), the acid-adapted S. Enteritidis and E. coli survived at higher levels in orange juice compared to non-acid-adapted populations (differences of around 1.7 log units between both). Finally, acid-adapted bacteria showed greater survival during passage through simulated gastrointestinal tract conditions, indicating increased pathogenic potential. Regarding the pathogenic potential, acid-adapted E. coli O157:H7 showed an adhesion capability of around 3.5 times higher in comparison with non-acid-adapted E. coli O157:H7. These results highlight the importance of considering the adaptability of foodborne bacteria to acidic conditions in food safety and security studies. Full article

Cacao mucilage is a rich medium for microbial development due to the presence of various sugars, water, pectin, mineral salts, and yeasts of the Saccharomyces cerevisiae type. This study aims to provide added value to this commonly discarded residue, thereby contributing to the economic growth of the Rio Chila area in the Valencia Canton of Los Ríos Province. The methods applied for developing beer consist of malting, grinding, mashing, filtering, boiling, cooling, fermentation (during which cacao mucilage is added), and maturation, followed by physical–chemical analyses. The Fine aroma cacao mucilage presented values of 0.66% acidity, 7.63 °Brix, pH 4.43, absorbance 1.13, transmittance 23.67%, suspended solids 0.04 g: 2.66%, density 1.07 g/mL, turbidity 6.94 NTU, °GL 8.47% vol., foam quantity 1.70 cm, colorimetry L* 50.77, colorimetry a* 18.08, colorimetry b* 50.53, and bitterness degree 39.00. The analyses presented values within the normal parameters applied to beers at the national level (INEN standards). Escherichia coli, Salmonella, and total microorganisms showed no contamination in the microbiological analyses. In the sensory analyses, appearance, aroma, flavour, and mouthfeel were evaluated, with the best experiment being the combination of Fine aroma cacao with a concentration of 30% mucilage and added Cascade hops. This study took into account the concentrations of cacao mucilage (20% and 30%) from the varieties (Fine aroma and CCN-51), as well as the addition of the brewing hops Cascade and Northern Brewer. Regarding the physicochemical characteristics, adding this cacao derivative did not affect craft beer and conformed to the ranges of the NTE INEN 2262 standard. Thus, this research proposes an alternative use for cocoa mucilage, contributing to waste reduction and broadening its potential applications. Full article

This study evaluates the potential role of two extracts derived from green and roasted coffee in managing Type 2 Diabetes (T2D). The phytochemical analysis revealed that the roasted coffee extract (RCE) contains higher levels of flavonoids and tannins, while the green coffee extract (GCE) seems to be richer in phenolic acids. No differences in the antioxidant activity of both extracts were observed. The study demonstrated that GCE exhibits stronger prebiotic potential by significantly enhancing the growth of beneficial probiotic bacteria when compared to the untreated sample. Both extracts inhibited α-amylase and α-glucosidase enzymes, with RCE demonstrating a better performance than other commercial treatments for T2D. Glucose uptake assays on yeast cells demonstrated that both extracts enhance glucose transport, particularly at low glucose concentrations, reducing supernatant glucose levels by 60–80%. Notably, GCE maintained its effectiveness even at the highest glucose concentrations tested. These findings suggest that coffee extracts, particularly GCE, may be useful as nutraceuticals for potentially regulating glucose metabolism and gut microbiota in T2D management. Full article

Kombucha, traditionally fermented from black or green tea, is well known for its potential health benefits. However, its high caffeine content may limit consumption for certain individuals. Therefore, this study aimed to develop a low-caffeine kombucha using lotus root tea as an alternative to black or green tea. Lotus root was roasted and brewed to prepare the tea base, to which sugar and a SCOBY were added for primary fermentation. Subsequently, Lactobacillus plantarum (1.0 × 10⁹ and 3.0 × 10⁹ CFU/mL) was inoculated to carry out secondary fermentation. The kombucha samples were assessed for their organic acid composition, antioxidant activity, antimicrobial effects, β-glucuronidase inhibition, and protective effects against Salmonella infection in a Caenorhabditis elegans model. The caffeine concentration of lotus root tea kombucha was significantly lower than that of conventional kombucha. L. plantarum fermentation increased the lactic acid concentration and enhanced antimicrobial activity, particularly against Escherichia coli OP50 and Salmonella typhimurium. Additionally, β-glucuronidase inhibition significantly improved, suggesting potential gut health benefits. In C. elegans, kombucha consumption improved survival rates following Salmonella infection, indicating a protective effect. This study demonstrates that fermentation using Lactobacillus plantarum can enhance the bioactivity of lotus root kombucha, highlighting its potential as a low-caffeine functional beverage.

Hop is a key ingredient in beer production, and drying it allows it to be stored before use. Unfortunately, postharvest drying techniques can negatively affect hop quality. In this study, we compared drying using a hot stove (H), freeze-drying (F), and ventilated at room temperature (VRT) drying, focusing on the chemical quality and essential oil composition. To achieve 80% water removal, F and H took two days, while VRT took five days. F and H preserved a high content of total chlorophyll (F 81.89 g/kg dm; H 82.70 g/kg dm) and carotenoids (F 54.02 g/kg dm; H 54.71 g/kg dm). The hop storage index (HSI) increased with all drying techniques, but especially in F and H. The lowest amount of polyphenols was found in the H sample (348.48 g/kg dm), while the highest content was found in VRT (631.11 g/kg dm). Freeze-drying gave the best results, especially in relation to the amount of polyphenols and antioxidant power of the product. Regarding essential oils, in the class of sesquiterpene hydrocarbons, we found α-humulene (F 24.0%; VRT 24.7%; H 25.6%), β-caryophyllene (F 10.5%; VRT 9.4%; H 11.1%), and β-farnesene (F 6.8%; VRT 6.0%; H 7.4%). The total monoterpene hydrocarbon amount increased in the VRT sample. Thus, freeze-drying emerges as an alternative technique to the hot stove; however, the cost is high. Instead, drying at ventilated room temperature represents a sustainable and valid technique for preserving the aromatic characteristics and polyphenols of the product. Full article

As an essential mineral element, selenium (Se) must be consumed by organisms through food and beverages. A method used to raise the amount of Se in food made from plants is biofortification, which is the process that increases the bioactivity and content of Se in the edible parts of plants. Foliar fertilization is the most feasible method of introducing selenium into the food chain. The objective of this work was to determine the effect of foliar biofortification with Selenium on various quality attributes of fruit species suitable for fruit-based beverage production, with the main goal of verifying the incorporation of Se into plant tissues. During the growing season in 2023, sodium selenate was applied in an equivalent of 150 g/ha Se in professional raspberry, blueberry, redcurrant, honeysuckle and apple plantings, from which fruit-based juice was later produced and analyzed. There was significant increase (p ≤ 0.05) in the Se content in the fruit’s juice, which was the main goal. Furthermore, after the application of Se under the mentioned conditions, there was a significant (p ≤ 0.05) increase in nutritionally valuable parameters, such as antioxidant activity, ferulic acid and resveratrol, but also the content of glucose, fructose, malic acid, total acids, Mn, Ba, Ca, Li, myricetin and chlorogenic acid content. On the other hand, a decrease in some valuable indicators, but also heavy metals (Al, Cu, Cr), were noticed in some fruit juices. Full article

Fruit brandy equipment commonly uses partial condensation (dephlegmation) to generate reflux in the distillation column. Here, we examined the effect of dephlegmation on the composition of fruit brandies in both lab-scale and large-scale settings. In lab-scale experiments, the dephlegmator led to a pronounced enrichment of ethanol in the distillate due to preferred condensation of water, while the concentration of flavor compounds was differentially affected. Some compounds were enriched in the distillate, some were depleted, and some were unaffected by dephlegmation compared with the control without a dephlegmator. Large-scale fruit brandy equipment relying exclusively on dephlegmation was compared as standard with an enrichment section containing three trays. In the equipment relying on dephlegmation, tail components such as fusel alcohols were less well separated from the middle run, which led to a reduced yield of clean spirit in the middle run. In triangle tests, the spirits from the two devices could be clearly differentiated, but there was no clear preference for one spirit or the other. This study provides for the first time detailed data on the influence of dephlegmators on the behavior of flavor compounds during fruit brandy distillation. Full article

The development of beverages with functional potential and maximum sensory acceptability are priorities for the food industry. This study investigated the effect of orange juice (OJ), lemon juice (LJ) and ginger juice (GJ) concentrations on overall acceptability (OA), total phenic compounds (TPC) and vitamin C (VC). The experimental design used was simplex-centroid mixtures, and maximization was achieved using response surface methodology (RSM). The bioactive content of TPC and VC was measured using the Folin–Ciocalteu method and the dichlorophenol indophenol method, respectively; sensory evaluation was conducted with 100 panelists on a continuous scale acceptability primer (0–10 points). The RSM results indicated that the optimum formulation was obtained with: OJ = 79.8 mL, LJ = 5.7 mL and GJ = 4.37 mL, yielding maximum values of OA = 6.81 points, TPC = 14.64 mg GAE/100 g and VC = 32.3 mg/mL. The optimized beverage presented a free radical scavenging capacity of 65.72% (DPPH method). The regression models were validated and significantly (p < 0.05) predicted sensory acceptability, total phenolic compounds and vitamin C content. The development of this beverage and its potential application in the food industry is attractive due to its high sensory acceptability and bioactive content. Full article

This study examined the ability of four beneficial strains (Lactobacillus rhamnosus LbRE-LSAS, Bifidobacterium animalis subsp. lactis Bb12, and two yogurt starters TA040 and LB340) to ferment MRS or milk containing free linoleic acid (0, 0.5, or 1 mg/mL). The goal was to produce an enriched conjugated linoleic acid (CLA) isomers’ yogurt-type beverage. Linoleic acid (LA) at 0.5 mg/mL did not interfere with the growth of the assayed bacteria on de Man Rogosa and Sharpe broth (MRS) or milk. On the other hand, increasing the content of LA in the MRS or yogurt-type beverage to 1 mg/mL slightly inhibited all strains and prevented accumulating high biomasses. A gas chromatography analysis of the fatty acid profiles confirmed the bioconversion of LA. The yogurt starters TA040 and LB340 had the highest bioconversion rates in the yogurt-type beverages, whereas the probiotic Bb12 strain was the most interesting at converting LA into its active CLA. CLA from the MRS supernatants of TA040, Bb12, and LbRE-LSAS had maximum antibacterial activities against S. typhimurium, E. coli, and S. aureus, respectively. Whey from the Bb12 beverage showed an inhibitory effect against all pathogens. These results suggest that all strains could be used as starter cultures in the proposition of a yogurt-type beverage with a high CLA content and antibacterial potential. Full article

The cashew apple constitutes approximately 90% of the total fruit mass produced by the cashew tree, with the remaining 10% being the cashew nut. Despite its high nutritional value, it is regarded as an agricultural byproduct. Numerous scientific studies have explored the technological and nutritional potential of the cashew apple by leveraging microorganisms in its fermentation process for beverage applications. This paper provides an overview of existing fermented cashew apple beverages and discusses perspectives for new fermented cashew apple products. Five fermented cashew apple beverages were recorded. These include wine, edible alcohol, probiotic and prebiotic beverages, and cashew apple-based vinegar. New fermented cashew apple beverages with organoleptic, nutritional, and functional properties can be considered. Among these are fermented cashew apple beverages such as kefir or kombucha-type drinks. A promising avenue for future research is the exploration of the indigenous microbiota of the cashew apple and their interactions within a consortium. This could lead to innovative developments in food technology and improvements in the organoleptic and nutritional characteristics of fermented cashew apple beverages. Full article

While studies on the co-fermentation of fruits and grapes are reported in the literature, blends of wine and fruit wine have never been investigated before. We characterised a blend (80:20 v/v) of Trebbiano Abruzzese white wine, organic kiwifruit wine, and the sparkling beverage obtained by its successive refermentation in a bottle. A persimmon/kiwifruit wine (50:50 v/v), after and before alcoholic fermentation, was also analysed. The buffer capacity, redox potential, concentration of selected polyphenols, total polyphenol content, antioxidant activity, and volatile profile were evaluated. The addition of kiwifruit wine to Trebbiano Abruzzese confers, to the final beverage, an appreciable improvement in terms of antioxidant activity, related to the content of polyphenols and ascorbic acid, which is substantially preserved in the sparkling product. Appreciable differences in the aroma of the blend compared to pure wine are mainly associated with the increased content of norisoprenoids, terpenes, methyl esters, and sulphur compounds, arising from the kiwifruit wine. The innovative beverages here proposed exhibit distinctive compositional and sensorial attributes that can be appreciated by consumers. Full article

Consumption of non-alcoholic beer (NAB) is continuously increasing in many countries. NABs are produced with varying technologies, resulting in different sensory properties. Previous studies have focused on understanding the consumers’ acceptance and preferences among different types of NAB. However, few studies have focused on the sensory characterization of commercial NABs produced with different methods. This study aimed to find key sensory characteristics in lager, Indian pale ale, and pilsner-type NABs with untrained panels by conducting tests in Finland and China. Participants were asked to Check-All-That-Apply for odors and Rate-All-That-Apply for flavors. Additionally, hedonic responses to odor and flavor pleasantness were rated. Chinese participants used more different and more often-used attributes to describe NABs. More varying descriptors were used on the NAB samples chosen as the most pleasant ones, indicating more complex sensory properties. Participants from both locations preferred lager-type beers characterized as ‘fresh’ odor and ‘fruity’, ‘floral’, and ‘sweet’ flavors and less frequently found Indian-pale-ale-type NABs pleasant, describing them as ‘sour’, ‘bitter’, ‘fermented’, and ‘pungent’ flavors. The flavor pleasantness correlated more with the samples frequently chosen as the most pleasant than odor pleasantness. No clear connection was found between the production method of NAB and consumers’ acceptance, demonstrating that all production methods can be used to produce non-alcoholic beers with sensory properties acceptable to consumers.

Background: Investigating fluid consumption among children and adolescents poses a challenge due to varying dietary behaviors and hydration needs. This systematic review aims to assess total water intake (TWI) and total fluid intake (TFI) in children and adolescents, focusing on gender differences and adherence to reference values proposed by the European Food Safety Authority (EFSA) and the Institute of Medicine (IOM). Methods: A systematic literature search of PubMed, Scopus, and Scholar was conducted to identify studies published between 2004 and 2024 reporting on TWI and TFI for children and adolescents. Studies were included if they reported fluid intake data in healthy populations, provided quantitative measures of TWI or TFI, and aligned with the EFSA or IOM reference values. From 8731 initial articles, 24 studies met the inclusion criteria. Data were synthesized narratively, and compliance with hydration guidelines was assessed. Results: The review included 24 studies, encompassing 16,254 children and 15,367 adolescents. The majority of participants failed to meet the recommended guidelines. Only one study reported compliance with the recommended TWI values, while four studies in children and four in adolescents showed adherence to the recommended TFI values. Conclusions: The results underscore a widespread inadequacy in achieving the hydration guidelines among children and adolescents, emphasizing the need for targeted interventions to improve fluid intake. Public health interventions are needed to promote adequate fluid intake, particularly in populations at risk of dehydration-related health outcomes. Future research should focus on identifying barriers to adequate hydration and developing targeted strategies to improve fluid intake behaviors. Full article

The present study aims to explore the possibility of applying machine learning (ML) algorithms for the development of reliable wine authentication instruments able to encompass the exhaustive performances offered by learning-based methods, and, at the same time, to propose reference practices for improving the recognition ability of the developed models. In this regard, two ML algorithms, namely k-Nearest Neighbors (kNN) and Logistic Regression, have been utilized as supervised learning techniques applied to ¹H-NMR spectral data for the development of classification models able to recognize the variety, geographical origin, and vintage of wine samples. Due to the complexity of the experimental data, which was characterized by a high number of variables, special attention was given to the preprocessing phase in order to identify the most relevant input space for each envisaged classification criterion. The obtained results have shown that ¹H-NMR spectroscopy in conjunction with Logistic Regression represents a reliable approach for wine traceability, leading, for all investigated classification criteria, to accuracy scores of the developed models greater than 98% in cross-validation and up to 100% in testing.

Demonstrating the authenticity and traceability of quality wines based on parameters that reflect their composition and provenance contributes to protecting wine authenticity and to increasing consumer confidence in moderate wine consumption, which is associated with numerous health-promoting properties. A wine’s phenolic fingerprint is increasingly used to assess its authenticity, even though wine phenolic composition is influenced by genetic and environmental factors, as well as vineyard management and enological practices, and storage conditions. This study presents a comprehensive analysis of the bioactive characteristics (total polyphenols—TPs, total flavonoids—TFs, antioxidant activity—AA, and total anthocyanins—TAs) by spectrophotometric analysis and phenolic compound profile (by UHPLC-HRMS analysis) of 19 white and 21 red wines with a Protected Designation of Origin (PDO) from four vineyards located in the wine-growing region of Oltenia, Romania. Multivariate statistical analysis, specifically principal component analysis and heat map analysis, applied to analytical data, enables the discrimination of wines based on grape variety and terroir, and across four consecutive vintages (2019–2022). The phenolic profiles of the wines obtained under standardized winemaking conditions depend on the climatic data specific to each harvest year (temperature, precipitation, duration of sun exposure during grape berry phenological stages, and ripening). The phenolic biomarkers of red wines, such as epicatechin, catechin, gallic, caffeic, t-ferulic acids, t-resveratrol and hesperidin, represent specific biomarkers of warmer and sunnier harvest years with lower precipitation, as observed in the 2021 harvest year. Additionally, our results contribute to the identification of specific phenolic biomarkers for geographical and varietal discrimination, as well as to the promotion of high-quality wines produced in a renowned wine-growing region of Romania.

Underwater aging of alcoholic beverages has gained growing interest in recent years as a novel strategy for product differentiation. This study investigated the effects of 12 months of underwater aging at 13 m depth on the chemical, volatile, and phenolic profiles of wine-based liqueurs, compared to traditional cellar aging. Individual bottles were analysed using an E-nose, achieving 96% correct classification in the cross-validated confusion matrix. Chemical analysis revealed no significant differences in pH, ethanol content, total and volatile acidity. Although total phenolic content did not differ significantly, underwater-aged liquors exhibited higher levels of anthocyanins, suggesting reduced degradation of phenolic compounds in the anaerobic underwater environment. This was supported by higher levels of free alpha-amino nitrogen and total proteins, suggesting slower oxidation. As a result, underwater-aged liquors showed a lower b* index (yellowness), likely due to the reduced oxidation of red colour compounds. Underwater aging induced some changes in the volatile profile, with a significant increase in certain furanones and pyranones, such as 5-hydroxymethylfurfural, 4-hydroxydihydro-2-(3H)-furanone and 3,5-dihydroxy-6-methyl-2,3-dihydro-4H-pyran-4-one, responsible for strawberry, toasted, and caramel notes. This increased production could be attributed to the unique underwater environment, characterised by oscillating vibrations, blue-green light, lower and more constant temperatures and reduced oxygen levels.
