Digital food-ordering apps make it simple to buy indulgent drinks yet hard to judge their health risks. We conducted five online experiments (N = 1048) to compare two messages for sugary beverages: self-promotion that stresses taste and self-disclosure that plainly warns “high sugar/high calories”. Brands that chose self-disclosure were seen as more socially responsible and transparent, which in turn raised trust and lifted purchase intent. These gains were strongest for users who care deeply about the category or the brand and remained robust even among highly health-conscious shoppers. The results show that, for “vice” foods, honest warnings can outperform glossy claims. Our study extends signaling and attribution theories to digital food markets and offers managers a straightforward playbook for complying with new labeling rules while still driving sales.

Background/Objectives: Despite evidence on the association between marketing unhealthy foods to children (M2K) and negative health outcomes, M2K remains widespread in Canada. To support mandatory restrictions, Health Canada has prioritized a monitoring strategy to assess the current state of M2K, identify gaps, and establish a baseline for future policy evaluation. This study aimed to support this initiative by updating the University of Toronto (UofT) Food Classification List and evaluating the proportion of foods and beverages in the Canadian grocery and restaurant food supply that would be permitted or restricted from M2K under Health Canada’s proposed nutrient profile model. Methods: Grocery items from the UofT Food Label Information Price 2020 (n = 24,949) and restaurant menu items from Menu-Food Label Information Price 2020 (n = 14,286) databases were evaluated using Health Canada’s M2K nutrient profile model, which assesses foods solely based on thresholds for added sodium, sugars, and saturated fat. The proportion of items permitted for or restricted from M2K was determined overall and by food and menu categories for grocery and restaurant items, respectively. Results: The updated UofT List contained n = 24,494 grocery items and n = 14,286 menu items. Overall, 83% (n = 32,664/39,235) of foods and beverages in the 2020 Canadian food supply would be restricted from M2K. Among grocery items, 23% (n = 5630) would be permitted and 77% (n = 19,202) would be restricted from M2K. Among restaurant items, only 6% (n = 837) would be permitted and 94% (n = 13,442) restricted. Conclusions: The updated UofT List supports Health Canada’s monitoring strategy and highlights the large proportion of unhealthy products in the Canadian food supply that are currently still permitted for M2K. While Health Canada’s M2K nutrient profile model is stringent, gaps remain that could allow continued M2K exposure under the current proposed policy. Ongoing monitoring and policy refinement are essential to effectively protect children from M2K and its harmful effects. Full article

Background: Ultra-processed foods (UPFs) represent a substantial part of modern diets, with a growing prevalence in food environments worldwide. Their unfavourable nutritional composition and adverse health effects present growing public health concerns. Methods: This study examines the prevalence of UPFs in the Slovenian food supply, their nutritional quality and the use of different food symbols and labelling schemes on food packaging. A cross-sectional analysis was conducted using the representative Slovenian branded foods database. A total of 23,173 prepacked foods and beverages were categorised into levels of processing according to the NOVA classification system. The nutritional composition of UPFs was compared to less processed products within 16 narrow subcategories. Additionally, the prevalence in the use of front-of-package nutrition labelling (FOPNL) and subjectively nutrition-related elements (SNREs) (such as EU Organic, Vegan labels etc.) were assessed across different food categories and processing levels. Results: Results show that UPFs represent 54.5% of the available products in the Slovenian food supply, with the highest prevalence in Confectionery (93%), Bread and bakery products (83%), Meat, meat products and alternatives (77%) and Convenience foods (74%). Comparison of nutritional composition indicated that UPFs had significantly poorer nutritional composition compared to less processed counterparts, including higher levels of sugar, salt and saturated fats, and a lower protein content. Breakfast cereals, Snack foods, Meat alternatives and Pre-prepared salads and sandwiches showed the most significant differences between UPFs and less processed counterparts. Analysis of the prevalence of symbols and labelling schemes revealed that 33.8% of products carried at least one FOPNL (15.0%) or SNRE (19.1%), with SNREs being more prevalent on less processed products and FOPNL predominantly used on UPFs (p < 0.05). The most prevalent SNRE was the EU Organic logo (12.7%), followed by the Vegan (4.7%) and Non-GMO (3.1%) logos, whereas the most frequent FOPNL was Reference Intakes (RI), presenting only energy value RI-Energy (12.5%), followed by nutrient-specific RI (1.6%), while other FOPNL were scarce and limited to certain categories. An additional comparison of visual presentation highlighted the potentially selective use of voluntary FOPNL to improve product framing. This raises concerns about their role in guiding consumer choices versus serving as marketing tools, especially when it comes to UPFs. Conclusions: Our findings highlight the need for monitoring UPFs in the food supply together with harmonised, mandatory labelling regulations to ensure transparency and empower consumers to make healthier choices.

Electronic noses (e-noses) are devices developed to recognize/classify odors and used in many fields, matching the current societal needs and concerns, such as food integrity and quality control, environmental monitoring, medical diagnostics, safety, and security in urban and industrial settlements. In this study, we review the application fields of e-noses based on a market analysis of currently available devices. A total of 44 companies active up to 2024, as well as 265 products, have been identified by considering the web pages of companies that feature e-noses among their products. These devices have been classified according to (i) the sensing mechanisms underlying the device performances and (ii) the application fields. The most diffused sensing devices/systems are chemiresistors (12.8%), electrochemical sensors (13.0%), catalytic beads (12.4%), and those based on optical detection techniques (16.0%). Commercial e-noses find large application in the industrial (21.0%) and chemical and petrochemical (21.0%) fields. A focus is made on the food and beverage application field, which is still a minor part of the overall share (6.0%) but is rapidly increasing and plays a relevant role in future applications where safety, sustainability, and quality issues are strictly intertwined. From this study, a rather complex picture emerges, and a proper taxonomy is expected to correctly classify the different kinds of e-noses. Full article

The market of plant-based food, including plant-based beverages, is one of the fastest-growing food sectors within the food industry and a subject of major research in the area of new product development. Plant-based beverages are a diverse group of non-dairy beverages with varying nutritional value, depending on the raw material sources and additional substances used in their production. A wide range of plant beverages makes it possible to choose products tailored to individual consumer preferences and needs as a part of sustainable dietary patterns. Increased consumer awareness of the environmental and health implications of proper nutrition, interest in plant-based diets, climate, and natural resource protection, as well as ethical concerns about animal welfare and the negative environmental impact of animal production, have led some consumers to seek a more balanced diet based on varied plant-based products, including beverages. Considering the highly diversified nutritional value of plant-based beverages, their availability, convenience, accessibility to consumers, ethical and environmental concerns, increasing health concerns as well as growing popularity of plant-based beverages as potential cow-milk alternatives, the Group of Experts in medicine and nutritional sciences presents the opinion on the nutritional value, health benefits and concerns of the available plant-based beverages. The opinion was based on a critical review of the current scientific literature, as well as on the experts’ experience. This knowledge can be used to make the right choices to improve the nutritional status and health of the consumers from different groups. Since the nutritional profiles of plant-based beverages vary across different plant-based drink varieties and they do not have standards of identity, in our opinion, there is a need for action to standardize nutrient fortification regarding the type and amount of added ingredients to ensure the safety of consumers and avoid potential over- or under-fortification of plant-based beverages.

Background: In response to criticism and limitations of the Nutri-Score Nutrient Profiling Model (NS-NPM), the algorithm was updated in 2023. However, its impact on beverage classification remains partially assessed. Objective: This study aimed to compare the nutritional profiles of beverages marketed in Spain using the original and updated NS-NPM algorithms. Methods: Nutritional data for 3432 beverages in the “Drink Base” database were analyzed using both the 2015 (original) and 2023 (updated) NS-NPM versions. Results: The 2023 update showed significant changes compared to the 2015 version. Updated scores particularly increased for artificially sweetened beverages (+190.3%), milkshakes (+98.9%), nut-based beverages (+343.9%), cereal-based beverages (+651.3%), and the mix of plant-based beverages (+733%), leading to a less healthy classification. Conversely, scores decreased for fruit juices (−12.7%) and alcohol-substitute beverages (−8.2%), while legume-based beverages maintained their classification with minimal score variation (−1.4%), raising questions about the treatment of free sugars. The remaining beverage categories experienced score changes that did not alter their classification. Conclusions: The 2023 NS-NPM algorithm improves beverage classification by refining the differentiation of sugar-sweetened and artificially sweetened beverages, improving consumer guidance. While it increases discrimination, challenges remain in the classification of plant-based beverages and fruit juices. These findings highlight Nutri-Score’s impact on industry reformulation and its potential as a public health tool to promote healthier beverage choices. This study provides novel evidence on how the updated Nutri-Score algorithm may influence consumer perception and food policy in the Spanish context. Full article

Plant milks are considered to be nutritious, sustainable, and vegetarian food products, and they have been the fastest growing beverages in the past decade in China. However, few studies have investigated consumers’ demands and purchase behaviors with respect to plant milks. Through an online questionnaire (n = 1052 valid responses), this study identified the factors that influenced individuals’ purchase intentions, purchase behaviors, attitudes, and demands with respect to current and future plant milk products. Through descriptive analysis and PCA, this study revealed that nutritional value (63.6%), taste (56.3%), and calories (42.8%) were the top three factors that Chinese consumers most cared about regarding plant milks. In the current Chinese market, coconut milk is the most popular plant milk with the highest purchase rate (61.2%), followed by soymilk (53.9%). Male consumers preferred plant milk with higher protein content and fortified with antioxidants, while female consumers preferred plant milk low in calories and enriched with collagen, dietary fiber, and probiotics. Chinese consumers are willing to pay higher prices for plant milks with enhanced nutritional value, improved product quality, and strengthened safety assurances. Innovative forms of plant milk, such as bean milk, rice milk, and quinoa milk, may be developed to satisfy the diversified needs of consumers. Full article

Hydroxyanthracene derivatives (HADs) are natural compounds that occur in several botanical species belonging to the genera Aloe L., Cassia L., Rheum L., Frangula Mill., and Rhamnus L. While they are widely used for their laxative effects, concerns persist about their potential genotoxicity and carcinogenicity. This study presents the development, validation, and application of a sensitive and rapid LC-MS/MS method to detect HAD (aloins, aloe-emodin, emodin, and danthron) levels in botanical food products and supplements. The method was validated according to criteria established by the European Union Reference Laboratory for Mycotoxins and Plant Toxins, and Regulation (EU) No 2783/2023 and was demonstrated to be fit-for-purpose. It was applied to 43 samples collected from the Italian market, including beverages, liquid and solid food supplements, herbal infusions, and jam based on aloe, senna, cassia, rhubarb, and frangula. The results revealed that 33% of the analyzed samples contained detectable HAD concentrations above the limit of quantification (LOQ = 0.5 mg/kg). The highest concentrations, up to 1352.9 mg/kg for the sum of aloin A and B, were found in solid food supplements derived from senna, cascara, rhubarb, and frangula. Aloe-emodin reached 213.4 mg/kg in a solid food supplement sample containing the same plant species, while the maximum detected concentration of emodin was 259.7 mg/kg in a senna-based supplement. No sample contained danthron. Conversely, in the majority of aloe beverage samples, HAD levels were found to be below the LOQ. In order to ensure the safety of consumers, it is essential that a more rigorous market surveillance of botanical food products is implemented, along with further toxicological studies. Full article

Background/Objectives: Artificial sweeteners (ASs) are food additives used to impart sweetness to various food products. Common sweeteners used individually or in combination include acesulfame-K, aspartame, cyclamate, saccharin, sucralose, and neotame. While traditionally considered harmless, emerging research suggest potential health implications. This study aims to analyze commonly consumed food products in Croatia for ASs presence, quantify four ASs, and estimate daily intake of ASs. Additionally, product labeling was assessed for compliance with Regulation 1169/2011 on food information to consumers. Methods: This study assessed the presence of acesulfame-K, aspartame, cyclamate, and saccharin dihydrate in 121 frequently consumed food products from the Croatian market using a high-performance liquid chromatography method. Based on obtained concentrations, data from a parallel consumption study, and existing literature on acceptable daily intake (ADI), we assessed exposure to ASs. Results: ASs were found in a substantial proportion of analyzed products, with multiple sweeteners often present in a single product. Specifically, ASs were detected in 74% of carbonated drinks, 54% of fruit juices, 86% of energy drinks, 70% of high-protein milk products, and 66% of chewing gums. Hypothetical consumption scenarios demonstrated that children, due to their low body mass, are at the highest risk of exceeding ADI values. Conclusions: The widespread presence of ASs in food products raises concerns about excessive intake, particularly among children who frequently consume soft drinks, instant beverages, and protein drinks. These findings highlight the need for further research into cumulative ASs exposure and its potential health effects, as well as the importance of public health strategies to regulate ASs consumption.

The essential amino acid tryptophan yields a plethora of secondary metabolites with key roles in plants and animals. Its fate in different living organisms is crucial for their own health, and metabolic profiling is a valuable tool for investigating it. Among the various metabolites, those retaining the indole structure were examined for qualitative and quantitative profiling. Liquid chromatography coupled with a tandem mass spectrometry detector with an electrospray ionization source (HPLC-ESI-MS/MS), acquiring in multiple reaction monitoring (MRM) mode, was used to develop a selective and sensitive method for the simultaneous analysis of tryptophan and 10 indole structure-retaining metabolites of it. Satisfactory values were obtained for linearity (R² ≥ 0.99 for all compounds except two), sensitivity (LOD, within 6–31 ng/mL, and LOQ, within 17–94 ng/mL, where minimum and maximum values were relative to serotonin and 5-methoxytryptamin, respectively), reproducibility (interday and intraday precision and accuracy), and effect of the matrix (recovery and matrix effect). The method was then successfully applied to the analysis of different types of beverage, such as herbal products, like Eschscholzia californica and a sleep herbal tea marketed with added melatonin (consumed to reduce anxiety and improve sleep quality), and fermented beverages, like beer and kefir. High amounts of tryptophan (from 77 ng/mL in kefir to 26,974 ng/g in the sleep herbal tea) followed by lower contents of serotonin (from 29 ng/mL in kefir to 2207 ng/g in the sleep herbal tea), were found in all samples along with the serotonin pathway-related compounds 5-hydroxytryptophan and tryptamine. Melatonin was detected in the plant matrix Eschscholzia c. for the first time to our knowledge (446 ng/g) and in the fermented beverages (96 ng/mL in beer and 39 ng/mL in kefir), regardless of their vegetable or animal origin, along with the melatonin route metabolites 5-methoxytryptamine and tryptophan ethyl ester. The amount of melatonin in the sleep herbal tea (556,464 ng/g) was in strong agreement with the declared content. Suggested applications include the search for biomarkers in phytochemical characterization, mechanistic studies of tryptophan’s chemistry, valorization of foods, beverages, and tryptophan-rich agro-food by-products and waste for nutraceutical and pharmacological purposes.

Nanoarchitectonics influences the properties of objects at micro- and even macro-scales, aiming to develop better structures for protection of product. Although its applications were analyzed in different areas, nanoarchitectonics of food packaging—the focus of this review—has not been discussed, to the best of our knowledge. The (A) structural and (B) functional hierarchy of food packaging is discussed here for the enhancement of protection, extending shelf-life, and preserving the nutritional quality of diverse products including meat, fish, dairy, fruits, vegetables, gelled items, and beverages. Interestingly, the structure and design of packaging for these diverse products often possess similar principles and methods including active packaging, gas permeation control, sensor incorporation, UV/pulsed light processing, and thermal/plasma treatment. Here, nanoarchitechtonics serves as the unifying component, enabling protection against oxidation, light, microbial contamination, temperature, and mechanical actions. Finally, materials are an essential consideration in food packaging, particularly beyond commonly used polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), and polyvinyl chloride (PVC) plastics, with emphasis on biodegradable (polybutylene succinate (PBS), polyvinyl alcohol (PVA), polycaprolactone (PCL), and polybutylene adipate co-terephthalate (PBAT)) as well as green even edible (bio)-materials: polysaccharides (starch, cellulose, pectin, gum, zein, alginate, agar, galactan, ulvan, galactomannan, laccase, chitin, chitosan, hyaluronic acid, etc.). Nanoarchitechnotics design of these materials eventually determines the level of food protection as well as the sustainability of the processes. Marketing, safety, sustainability, and ethics are also discussed in the context of industrial viability and consumer satisfaction. Full article

Background/Objectives: Oral administration of active pharmaceutical ingredients (APIs) is the most commonly used route of administration. As dysphagia is a prevalent problem, the size of the swallowed dosage form could negatively influence patient adherence. Orally disintegrating tablets (ODTs) are beneficial dosage forms because they disintegrate within a few seconds in the oral cavity without water. Lactose is one of the most commonly used excipients in the pharmaceutical industry; it served as the central concept of a recent publication on the formulation of milk-based ODTs despite lactose malabsorption being widespread worldwide. Consequently, the plant-based alternative market has grown exponentially and has become a prevailing food trend, with various alternatives to choose from. For this reason, the development of a nonsteroidal anti-inflammatory drug (NSAID)-containing ODT with plant-based drinks (PBDs) was assessed for its innovative potential. Methods: Different PBDs were investigated and compared to traditional and lactose-free milk. The liquids’ viscosity, pH, and particle size were determined, and an electronic tongue was used for the sensory evaluation. The various ODTs were prepared with the freeze-drying method, and then the qualitative characteristics of the dosage form were investigated. Results: Our different measurements show that different plant beverages differ from each other and that these differences have an impact on the technological processing. According to the HPLC-DAD measurements, all values were in the required range. Conclusions: These measurements suggest that the soya drink is the most similar to traditional cow milk and would be the most appropriate choice among the investigated plant-based drinks to be used as a carrier system for an ibuprofen-containing ODT.

Background: It is common for consumers to purchase ultra-processed foods that are perceived to have health risks, and this phenomenon is rarely explained in the existing literature from the perspective of consumers’ responses to the intuitive marketing of flavor labels and the packaging. Methods: This study aimed to fill this knowledge gap and investigated the attention of 920 participants aged 18~59 across China toward fat and sodium content information for six ultra-processed foods (pastry foods, quick-frozen foods, dessert foods, puffed foods, beverages, and sauces) presented in nutrition facts tables based on the theoretical analysis framework for purchasing decisions on ultra-processed foods by using the binary logit model. Results: It was found that the respondent’ s attention to fat and sodium content information was positively influenced by health risk perception levels and levels of knowledge about fat and sodium but negatively influenced by the interaction term between flavor labels (or the packaging) that stimulated the purchase desire and health risk perception levels (or levels of knowledge about fat and sodium). Conclusions: The stimulation of purchase desire by flavor labels and the packaging weakened the consumer’ s increased attention to fat and sodium content information being enhanced by the health risk perception level and the level of knowledge about fat and sodium, especially the probability of attention to such information for dessert foods, puffed foods, quick-frozen foods, and sauces, which dropped the most. Additionally, the attention of females, youth, low-income individuals, those with below-college education, and non-overweight and obese individuals to such information dropped more, and the decrease was the largest for dessert foods, puffed foods, quick-frozen foods, and sauces.

Background/Objectives: This study explores the significance of beetroot and tomato juices, two prominent health-promoting foods known for their rich nutrient content and bioactive compounds. The growing consumer awareness of the link between diet and well-being emphasizes the need for food producers to align their products with health-conscious preferences. The aim of this research was to assess the composition, color, and sensory attributes—specifically color, taste, and odor—of various commercially available beetroot and tomato juices and to evaluate their acceptability among consumers. Methods: A total of 50 dietitians (41 women and 9 men) participated in sensory evaluations and spectrophotometric color analysis using the CIELAB system, which measures lightness (L*), red–green tones (a*), and blue–yellow tones (b*). This dual approach allowed for a comprehensive understanding of how color characteristics correspond to sensory ratings. Results: Results revealed significant differences in color and sensory attributes among the juices, with darker hues and higher red-tone values generally preferred by consumers. Juices with lower lightness (L*) and dominant blue or red tones (negative b*, higher a*) were consistently rated higher, suggesting that color plays a pivotal role in initial product acceptance. However, no single juice excelled across all sensory categories, indicating varied consumer preference. Conclusions: The findings underscore the influence of color on consumer perception and its potential for guiding product development. For producers of functional beverages, optimizing visual appeal through precise control of color parameters could enhance marketability while balancing sensory attributes such as taste and aroma. These insights support the development of products that satisfy both nutritional goals and consumer expectations. Full article
