The high environmental impact caused by the accumulation of single-use plastic calls for measures to curb this problem, from a ban on single-use plastic tableware to the production of a wide range of biodegradable and reusable products. The aim of this study was to investigate how tableware made of different materials affects consumers’ sensory perception and emotional and hedonic responses when eating the same meal. In this study, four types of meals of animal or plant origin were selected for the experiments, which were served warm or cold. Accordingly, four groups of university students were instructed to taste the corresponding meal while using three sets of tableware made of different materials: polypropylene, wood/cardboard, and a stainless steel/ceramic/glass control set (regular set). Overall, the results suggest that the use of regular tableware elicited a positive emotional profile, while the use of disposable, wooden, and plastic tableware elicited negative emotional responses, which is consistent with the acceptability of the meal samples—regular tableware received higher ratings, while both types of disposable tableware received lower ratings. Finally, the material of the tableware only led to changes in odor and flavor perception when warm-served meals were sampled—higher intensities were reported when students used the regular tableware sets. Wooden cutlery imparted an atypical woody flavor to the meals, regardless of the type of meal. Full article

The valorization of agro-industrial by-products is a key component of sustainability goals in food production. Olive pomace (OP), a major by-product of olive oil extraction, is characterized by a high content of dietary fiber and bioactive phenolic compounds with antioxidant activity, which contribute to its nutritional and functional potential. The present study investigated the effect of the fortification of sheep milk yogurt with freeze-dried OP (1% w/w), added either before pasteurization (YOPB) or after overnight refrigeration (YOPA). The OP showed considerable antioxidant capacity and was microbiologically safe. Its addition significantly increased the yogurt’s total phenolic content, with YOPB displaying the lowest syneresis and the highest water-holding capacity and apparent viscosity. Textural and scanning electron microscopy analyses revealed that the timing of OP addition affected the gel structure, with pre-pasteurization incorporation facilitating a superior integration into the protein network. The microbial viability was preserved, and the sensory evaluation showed no significant differences in consumer acceptance between the control and YOPB. These findings highlight OP’s potential as a functional ingredient for dairy fortification, contributing to waste reduction and improving gel structure. The findings obtained provide support for the development of sustainable and functional dairy products enriched with by-products derived from the olive oil industry. Full article

The growing awareness of celiac disease and gluten sensitivities has generated interest in gluten-free products. Whole sorghum (Sorghum bicolor) is an excellent source of nutrients and is gluten-free. However, the absence of gluten makes it technologically challenging to produce leavened products. This research aims to utilize a response surface methodology to optimize the specific loaf volume and crumb firmness of a whole sorghum-based gluten-free bread formulation, evaluating different levels of milk powder, egg white, yeast, sugar, psyllium husk powder, xanthan gum, and soy lecithin. The models fit achieved an $R^2\ge 80\%$. The optimized formulation increased the specific loaf volume from 1.7 to 2.8 cm³ g⁻¹ and decreased crumb firmness from 10.6 to 3.7 N compared to the initial gluten-free bread formulation (C1). Egg white, milk powder, and psyllium contribute to the formation of a gluten-like network, which enables gas retention, dough expansion, and volume increase. In addition, soy lecithin, among hydrocolloids, enhances dough stability and moisture retention, resulting in a softer crumb. Sensory evaluation indicated good consumer acceptability (average score of 7 on a 9-point hedonic scale), particularly for texture and flavor. These findings suggest that optimal formulation of sorghum achieves both technological and sensory properties, supporting its potential as a viable gluten-free bread alternative. Full article

Hybrid meat products, i.e., the combination of animal proteins with plant, microbial, algal or cultured ingredients, are becoming increasingly important as a pragmatic approach to reducing the environmental and health impact of conventional meat while retaining familiar sensory properties. This review highlights that moderate substitution rates (20–50%) can maintain or improve texture, juiciness and nutritional balance, whereas higher incorporation rates often lead to off-flavours, colour changes and texture issues. Advances in extrusion, co-processing and protein structuring have enabled increasingly sophisticated formulations. Studies show that the choice of ingredients has a strong influence on the sensory results. For example, faba beans, rice by-products or insect proteins are more acceptable at low to moderate levels, while excessive use of pulses or texturised proteins can produce beany or earthy notes. Nutritional improvements, such as more fibre and healthier fatty acid profiles, are possible but require careful optimisation. Consumer acceptance is increasing, particularly among flexitarians, but remains dependent on sensory performance, familiarity, and perceived health benefits. Ongoing obstacles include unclear regulatory requirements, high production costs and scalability issues. Future progress will require optimisation of ingredient blends, robust life cycle assessments to verify sustainability claims and transparent communication to increase consumer confidence.

Grape pomace (i.e., the residual skins, seeds, and pulp left after vinification) retains up to 70% of the fruit’s original phenolic compounds and is also rich in dietary fiber. As such, because this by-product is generated in large quantities worldwide and its disposal is both technologically problematic and costly, reusing it as a food ingredient could simultaneously mitigate environmental burdens, lower winery waste-management expenses, and enhance the nutritional profile of fortified foods. In this context, this study investigated the nutritional enrichment of dark chocolate by incorporating flour produced from red (cv. Syrah) and white (cv. Arinto) grape pomace at three levels (5, 10, and 15% w/w). Formulated chocolates and controls were manufactured under industrial tempering conditions and subsequently analyzed for protein, lipids, sugars, dietary fiber, total phenolic content, antioxidant capacity (DPPH and ORAC), color, texture, and consumer perception (hedonic test). All fortified samples showed higher fiber and antioxidant activity than the control, with “White_15” showing higher fiber content (43.1%) and “Red_5” for ORAC (69,483 µmol TE/100 g) and DPPH (6587 µmol TE/100 g). Dietary fiber showed an increase in content with the increase in grape pomace incorporation, regardless of the type (red or white). Texture softening was observed in all fortified chocolates independently of the incorporation level or type (red or white). Principal Component Analysis (PCA) and hierarchical clustering confirmed clear separation between control and fortified chocolates based on the parameters analyzed. Sensory evaluation with untrained panelists revealed good overall acceptability across all formulations. These findings demonstrate that grape pomace flour can be effectively valorized as a functional ingredient in dark chocolates, supporting circular economy practices in the wine and confectionery sectors while delivering products with enhanced health-promoting attributes (nutritional and antioxidant).

Yerba mate (Ilex paraguariensis) is widely consumed in South America and is valued for its bioactive compounds, such as polyphenols and methylxanthines. However, during traditional processing, mainly in the fire-based scorch and drying steps, polycyclic aromatic hydrocarbons (PAHs) and anthraquinone (AQ), substances with carcinogenic potential, may be formed. This study aimed to develop and validate an analytical method based on the balls-in-tube matrix solid-phase dispersion technique (BiT-MSPD) and analysis by gas chromatography with mass spectrometry (GC-MS) for the simultaneous determination of 16 priority PAHs and AQ in yerba mate. Parameters such as sorbent type, solvent, sample-to-sorbent ratio, and extraction time were optimized. The method showed good linearity (r² > 0.99), detection limits between 1.8 and 3.6 µg·kg⁻¹, recoveries ranging from 70 to 120%, and acceptable precision (RSD ≤ 20%). The method was applied to 31 yerba mate samples, including 20 commercial samples and 11 collected at different stages of processing. Most commercial samples showed detectable levels of PAHs, with some exceeding the limits established by the European Union. AQ was detected in 40% of the samples, with some values above the permitted limit of 20 µg·kg⁻¹. The results confirm that scorch (sapeco) and drying contribute to contaminant formation, highlighting the need to modernize industrial processing practices. The proposed method proved to be effective, rapid, and sustainable, representing a promising tool for the quality control and food safety monitoring of yerba mate. Full article

The A1 and A2 variants of bovine β-casein (CSN2) have gained attention in the dairy industry due to potential health effects. The A1 variant, prevalent in Holstein-Friesian cattle, is a major source of β-casomorphin-7 (BCM-7)—an opioid-like peptide released during digestion and associated with lower digestive comfort. In this study, β-casein A1 and A2 variants and BCM-7 levels were quantified in raw milk and three commonly consumed dairy products (pasteurized milk, UHT milk, and milk powder) using ELISA. The samples came from dairy plants within a single operating zone. The A1 variant was significantly more frequent (13.69–22.41 ng/mL) than the A2 variant (8.10–12.60 ng/mL), although the local Holstein cattle population had a higher frequency of the A2 allele (63%) than A1 (37%). This discrepancy could be due to a more efficient expression of the A1 allele in cows with heterozygous or A1A1 genotypes. BCM-7 levels were low and did not vary significantly with CSN2 genotype or processing method. These results provide new insights into the composition of dairy products and contribute to the ongoing debate on the health implications and consumer acceptance of milk with the A1 β-casein variant.

The rise of financial technology (FinTech) has generated substantial research on its adoption by customers and the associated implications for traditional banks. This systematic review addresses two questions: (1) What factors enable or hinder consumer adoption of FinTech? (2) How does consumer adoption of FinTech affect the performance of traditional banks? Following the PRISMA guidelines, we screened and analyzed 109 peer-reviewed articles published between 2016 and 2024 in Scopus and Web of Science. The findings show that adoption is driven by economic incentives, digital infrastructure, personalized services, and institutional support, while barriers include limited literacy, perceived risk, and regulatory uncertainty. At the bank level, adoption enhances operational efficiency, customer loyalty, and revenue growth but also generates compliance costs, cybersecurity risks, and competition. Consumer adoption studies primarily employ the Technology Acceptance Model (TAM) and the Unified Theory of Acceptance and Use of Technology (UTAUT), often extended with trust and privacy constructs. In contrast, bank performance research relies on empirical analyses with limited theoretical grounding. This review bridges behavioral and institutional perspectives by linking consumer-level drivers of adoption with organizational outcomes, offering an integrated conceptual framework. The limitations include a restriction of the retrieved literature to English publications in two databases. Future work should apply longitudinal, multi-theory models to deepen the understanding of how consumer behavior shapes bank performance. Full article

Alternative proteins (APs) have the potential to contribute to the sustainable transition of food systems. This study aims to assess the current stage of development of the alternative protein industry, identifying factors, both barriers and enablers, that influence business growth. The analysis adopts a systematic literature review, following the PRISMA guidelines, identifying 50 studies. The S-curve model is then applied as an analytical tool to determine the development stage of the AP industry concerning plant-based, insect, and algae segments. The application of the S-curve provides a perspective on the evolution of innovative business such as AP. The results reveal significant differences in the maturity of the AP industry. The plant-based one is the most advanced, characterized by strong market organization and collaborations, despite challenges such as price competitiveness. The algae industry is promising due to its versatility, yet it is hindered due to production costs and unstable demand. Insects face the greatest barriers, including consumer acceptance and ethical concerns. The study emphasizes the importance of creating business strategies suited to each AP source to transform barriers into opportunities. This review contributes to the literature by comparing the unique peculiarities of the AP industry and providing insights from a cross-analysis of plant-based, algae, and insect development stages.

Losses resulting from food processing have encouraged the search for sustainable alternatives for the use of agro-industrial by-products. Melon is a fruit widely consumed in Brazil, but during its processing, by-products are generated, such as peels. This study utilized yellow melon peels to produce flour and incorporated it into the formulation of vegan and gluten-free muffins. Three muffin formulations were processed, with the partial replacement of rice flour by melon peel flour (MPF): Control (0%), F10 (10%), and F20 (20%). The flour and muffins were characterized according to their physicochemical properties. The muffins were evaluated based on color, texture, expansion factor, height, specific volume, and sensory acceptance. Considering the fiber and ash content (17.38 g/100 g and 10.14 g/100 g, respectively), MPF can be classified as a food with “high fiber and mineral content”. The specific volume of the muffins ranged from 1.403 to 1.756 cm³/g, with the lowest value found for the muffins made with the highest amount of MPF (F20). The muffins with 20% MPF had the lowest expansion factor (1.213 mm) due to the higher amount of fiber (4.45%). The most accepted sample was the F10 formulation (7.21), with an acceptance index of 88.88%. Full article

Given the growing consumer demand for improved quality of life and health-promoting foods, replacing conventional fats in widely consumed products such as bread with oils derived from native Brazilian fruits represents a promising strategy. This study aimed to evaluate the bioactive and technological potential of buriti (Mauritia flexuosa) and acuri (Attalea phalerata) oils, extracted from palm fruits native to the Cerrado and Amazon biomes. Both oils proved to be rich sources of lipophilic bioactives, particularly carotenoids, tocopherols, and phenolic compounds, and exhibited excellent carotenoid bioaccessibility under in vitro digestion, with recovery rates of 74% for acuri oil and 54% for buriti oil. Notably, buriti oil showed a high β-carotene content (1476.5 µg/g). When incorporated into sandwich bread formulations, these oils enhanced antioxidant activity, improved texture, volume, and color, and maintained high sensory acceptance compared to bread made with soybean oil. Sensory evaluation scores averaged above 7 for all tested attributes. These findings underscore the industrial applicability of buriti and acuri oils as functional lipids aligned with sustainable development and nutritional innovation. Full article

The incorporation of probiotics into food products has gained substantial attention, primarily due to their well-documented health benefits such as modulating gut microbiota, enhancing immune responses, and providing potential therapeutic effects. This comprehensive review discusses recent advancements in the application of probiotics in the food industry, focusing on diverse food matrices, technological and regulatory challenges, and consumer acceptance. Particular emphasis is placed on fermentation-based approaches that enhance both sensory and nutritional attributes, while acting as effective delivery systems for viable probiotics. The impact of matrices such as dairy, meat, cereals, plant-based beverages (e.g., soy or almond milk), and solid plant-derived foods (e.g., fermented vegetables) on probiotic survival, sensory properties, and product acceptability is critically examined. Understanding these interactions is crucial for the development of stable, efficacious, and consumer-oriented probiotic-enriched functional foods. Full article

This paper examines the risks linked to E-business collaboration between China and West Africa, with particular emphasis on Ghana as a pivotal digital commerce centre. This research employs the Hesitant Fuzzy Best–Worst Method (HF-BWM) to systematically identify and prioritise the institutional, technological, sociocultural, and legal issues affecting cross-border e-business operations. This study combines Transaction Cost Theory (TCT), the Technology Acceptance Model (TAM), and Commitment–Trust Theory to create a comprehensive framework for analysing the interplay of these risks and their effects on transaction costs and company sustainability. The findings indicate that institutional risks constitute the most substantial obstacles, with deficient digital transaction legislation and inadequate data governance recognised as the principal drivers of uncertainty and increased transaction costs. The research indicates that these institutional challenges necessitate immediate focus, as they immediately affect corporate operations, especially in international digital commerce. Technological risks, such as cybersecurity vulnerabilities, insufficient IT skills, and deficiencies in digital infrastructure, were identified as the second most critical factors, leading to considerable operational disruptions and heightened expenses. Sociocultural hazards, such as language difficulties and varying consumer behaviours, were recognised as moderate concerns that, although significant, exert a weaker cumulative impact than technological and institutional challenges. Eventually, legal risks, especially concerning cybercrime legislation and the protection of intellectual property, were identified as substantial complicators of e-business activities, increasing the intricacy of legal compliance and cross-border contract enforcement. The results underscore the imperative for regulatory reforms, investments in cybersecurity, and methods for cultural adaptation to alleviate the identified risks and promote sustainable growth in China–West Africa e-business relationships. This study offers practical insights for governments, business leaders, and investors to effectively manage the intricate risk landscape and make educated decisions that foster enduring collaboration and trust between China and West Africa in digital trade.

Plant-based beverages are a viable alternative for elderly consumers because of their practicality and sustainable appeal. The use of Brazil nuts for these beverages is relevant because of the added value given to the country’s agrobiodiversity and the nuts’ nutritional quality, including their high selenium content. This study aimed for the understanding and acceptance by elderly people of a vegetable beverage made from Brazil nuts and fruit. The investigation was divided into two parts: (1) development and sensory analysis of Brazil nut beverages, and (2) consumers’ perception, choice, and influencing factors for these beverages. In the first stage, four beverages were formulated with different fruit pulps. A total of 100 elderly individuals (>60 years; 69% female) evaluated the sensory acceptance and purchase intention of the beverages. In the second stage, an online questionnaire was applied to 220 elderly individuals (>60 years-old; 52.7% female), which consisted of a choice test of nut beverage packages, a food neophobia scale, and questions about vegetable beverage consumption. The study showed that the selenium claim was one of the most relevant factors in the choice, demonstrating that using Brazil nuts can boost beverage purchases. Further tests are still needed to improve the attributes, such as sweet taste and appearance. Despite this, the blend of Brazil nuts with fruits positively influenced the choice and acceptance of these products by elderly individuals. Full article
