Modified atmosphere packaging (MAP) is a preservation and packaging technology used to extend the shelf life of foods and agricultural products, maintain quality stability, and ensure food safety. To systematically review and summarize the current research landscape, technical challenges, and development trends in the MAP field, this study selected 1568 publications related to MAP from the Web of Science Core Collection (WOSCC) database during 2016–2025 and conducted bibliometric and visualization analysis. The results indicate that research activity in the MAP field has remained robust over the past decade, mainly focusing on four research areas: atmosphere regulation and packaging system design; microbial ecology, safety, and spoilage control; physicochemical deterioration and quality regulation; functional packaging materials and integrated preservation technologies. Countries such as China, Italy, and Spain have demonstrated outstanding performance in terms of publication output and academic influence in the MAP field, forming a solid research foundation in the MAP of perishable foods such as fruit and vegetables, meat products, and aquatic products. Research in the MAP field has gradually shifted from the verification of application effects toward system design and mechanistic analysis. Active packaging, intelligent packaging, bio-based materials, natural functional ingredients, volatile organic compounds, microbial community succession, and quality deterioration mechanisms have gradually become research hotspots, indicating a trend toward precision, sustainability, and functionality. These findings may provide references for future research topic selection, innovative packaging system design, and the development of novel food preservation technologies in the MAP field for foods and agricultural products.

This study evaluated the antimicrobial activity of meads produced by mixed fermentation of Saccharomyces cerevisiae var. boulardii and a kombucha culture, using eucalyptus- and rosemary-monofloral honeys. Antimicrobial activity was investigated in vitro against pathogenic bacteria (Escherichia coli, Salmonella enterica, Listeria innocua, Staphylococcus aureus, and Bacillus cereus) and spoilage yeasts, over 28 days of storage. All tested matrices were autoclaved at 121 °C for 15 min before antimicrobial evaluation to eliminate viable fermentation microorganisms. Additionally, assays were conducted in simulated food systems at different substrate concentrations, characterizing organic acids, reducing sugars, and volatile compounds. Unfermented musts allowed survival of L. innocua and B. cereus, with rosemary honey showing stronger antimicrobial effects than eucalyptus. Kombucha exerted strong initial inhibition, possibly associated with its high organic acid concentrations, but did not completely inhibit the growth of Gram-positive bacteria. No pathogenic bacterial growth was detected in the fermented mead matrices, possibly due to reduced fermentable sugars, ethanol, organic acids, and other fermentation metabolites. Spoilage yeasts showed high tolerance to acid and osmotic stress, and efficacy decreased in substrate-rich systems. Importantly, the antimicrobial activity reported here refers specifically to autoclaved fermented matrices and does not necessarily apply to untreated fermented beverages. Full article

Biorefineries that convert the organic fraction of municipal solid waste (OFMSW) into advanced biofuels can integrate waste management with renewable energy production. However, their environmental performance remains insufficiently characterised owing to a scarcity of life cycle assessment (LCA) studies based on real operational data. This study presents a gate-to-gate LCA of a demonstration biorefinery processing source-separated food waste into bio-oils, bioethanol, and biogas. The ReCiPe 2016 Midpoint (H) method was applied across 18 impact categories, with system expansion crediting the displacement of rapeseed oil, maize-derived ethanol, and marginal biogas-derived electricity. The net global warming potential (GWP) was 68.5 kg CO₂ eq per tonne of wet OFMSW (69% reduction from gross), placing the biorefinery 83–93% below landfilling, 63% below incineration with CHP, and above standalone anaerobic digestion systems that lack the energy-intensive drying and enzymatic hydrolysis steps of the present configuration. Bio-oil and bioethanol achieved net-negative GWP per kilogram of product (−0.89 and −0.66 kg CO₂ eq, respectively), whilst eleven of eighteen categories achieved net savings under system expansion. Enzyme production dominated the bioethanol environmental profile (37–94% across categories), whilst drying dominated bio-oil (46–93%). Monte Carlo simulation confirmed that the sign of the net impact stayed unchanged across the entire 95% confidence interval (the interval did not span zero) for 17 of 18 categories. Full article

As the global agri-food system faces escalating climate-related challenges, developing localized low-carbon short food supply chains (SFSCs) has become a vital strategy for sustainable agriculture. To elucidate the psychological drivers of green consumer behavior within this context, this study integrates the Stimulus–Organism–Behavior–Consequence (SOBC) framework with the Theory of Planned Behavior (TPB). The aim is to investigate the continuous purchase intentions of Taiwanese consumers for organic cocoa. Data collected via an online survey from 377 consumers with prior cocoa consumption experience were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results indicate that personal attitudes and perceived behavioral control positively drive consumption intentions, whereas subjective norms do not. This suggests that consumption behaviors rely on substantive product evaluation rather than social pressures. Additionally, green product attributes and environmental values significantly enhance TPB constructs. Importantly, consumption intentions translate positively into perceived consumer effectiveness and continuous purchase intentions. By elucidating the psychological mechanisms underlying sustainable food choices, this study highlights the value of Taiwan’s “Tree-to-Bar” model. Practically, the findings highlight potential implications for policymakers and agribusinesses regarding how environmental attributes are communicated through front-of-pack (FOP) labels that emphasize local production and low-carbon mileage. Such approaches may help make environmental information more accessible to consumers, although their effectiveness should be evaluated in future research. Full article

Smart chemical sensors have emerged as promising tools for real-time monitoring of food spoilage in both fermented and non-fermented products. By detecting key spoilage indicators—including biogenic amines, ammonia, hydrogen sulfide, methane, pH variations, and microbial volatile organic compounds (MVOCs)—these systems enable rapid, on-site assessment of food quality, offering a viable alternative to conventional, time-consuming laboratory analyses. Recent advances encompass diverse sensing mechanisms, including chemiresistive platforms based on conducting polymers and MEMS (Microelectromechanical Systems); optical/colorimetric systems using dyes, metal–organic frameworks, and porphyrins; and electrochemical and biosensing approaches employing enzymes, antibodies, aptamers, and whole-cell recognition elements. These sensors demonstrate high sensitivity (ppb–ppm range), enabling early detection of spoilage before sensory perception or microbiological threshold exceedance. Their applicability has been validated across a wide range of food matrices, including meat, fish, dairy products, vegetables, beverages, and fermented foods. Despite significant progress, key challenges persist, including signal drift, limited specificity, susceptibility to environmental factors such as humidity and temperature, and interference from complex food matrices. Furthermore, integration into intelligent packaging requires the development of flexible, food-safe, and regulatory-compliant materials. Emerging approaches that combine sensor arrays with machine learning and MVOC pattern recognition are enhancing predictive accuracy and enabling food classification across commodity types. Overall, smart chemical sensing technologies are rapidly transitioning from laboratory prototypes to practical applications in intelligent packaging and wireless monitoring systems, with ongoing research focused on improving robustness, standardization, and scalability for commercial deployment. This article provides an overview of the topic, drawing on the available bibliography from the last five years and the most-cited scientific databases. Full article

Background/Objectives: Choline is an essential nutrient, and deficiency is associated with metabolic dysfunction-associated steatotic liver disease. Research shows that Western populations have inadequate choline intake; however, the intake in Asian populations is less studied. This study developed a choline database for Thai food and evaluated intake in the Thai population. Methods: Following guidelines of the Food and Agriculture Organization/the International Network of Food Data Systems, 1806 Thai food items were matched to the U.S. choline database, and the missForest imputation method was used to impute missing data. Choline intake was assessed in Thai adults aged 18 years and older using a nationally representative sample of the Thai Food Consumption Survey (n = 3593). Results: Animal-based foods such as eggs, meat, and fish contained more choline than plant-based foods. Median choline intake was 134.7 mg/day (IQR: 70.6, 229.3), with 3.6% of Thai individuals meeting adequate intake levels. Men consumed more choline than women (median 153 vs. 120 mg/day; p < 0.001). Choline intake declined with age but did not differ by body mass index. Conclusions: This study created a choline database for Thai food and shows that most Thais have intake below the recommended intake levels. Full article

Small-scale fisheries are socio-ecological systems in which resource users interact with environmental conditions, fishing regulations, community initiatives, and institutional actors. Understanding how fishers perceive and report these interactions provides information on the social context of fisheries management, although such perceptions cannot substitute for independent assessments of ecological sustainability, behavioural compliance, or governance effectiveness. This study characterized fishers’ environmental perceptions, self-reported fishing practices, participation in environmental education and conservation activities, and perceptions of community and institutional involvement in fisheries management in Tecomate Lagoon, Guerrero, Mexico. A cross-sectional quantitative design was used, and structured questionnaires were administered to 120 active artisanal fishers selected through simple random sampling. Data were analyzed descriptively using frequencies and percentages. Respondents primarily associated the lagoon with economic (49.17%) and food-related (25.83%) functions. Declining water levels (60.00%) and reduced species abundance (40.00%) were the environmental changes reported by respondents. Regarding fishing practices, 94.17% stated that they complied with fishing regulations, and 100% reported releasing organisms below the minimum legal catch size. Environmental training was reported by 95.00% of respondents, while 94.17% reported participation in conservation-related activities. CONAPESCA (80.83%) and UAGro (19.17%) were identified as institutions involved in fisheries-related initiatives. These findings characterize the perceptions and self-reported experiences of surveyed fishers and should not be interpreted as evidence of ecological sustainability, actual behavioural compliance, educational effectiveness, or governance performance. The contribution of the study lies in systematically documenting the resource-user perspective as a component of the social dimension of the fishery. This information provides a descriptive baseline that can complement future ecological, behavioural, institutional, and longitudinal assessments of small-scale fisheries in coastal lagoon systems.

The growing demand for eggs from alternative housing systems is driven by perceived nutritional and welfare benefits. However, the trade-off between enhanced bioactive composition and exposure to environmental contaminants remains insufficiently explored. This study evaluated the physical traits, bioactive compounds, and heavy metal content of 480 commercially available table eggs from four housing systems: organic, free-range, barn, and enriched cages. Organic eggs exhibited the highest albumen quality, expressed by Haugh units (92.03 vs. 70.86 in cages) and lysozyme activity (144,877 U/mL vs. 119,830 U/mL in cages), alongside the highest concentrations of fat-soluble vitamins (e.g., vitamin A at 1600 μg/100 g and vitamin E at 3267 μg/100 g) and n-3 polyunsaturated fatty acids, including docosahexaenoic acid (DHA: 0.673% vs. 0.360% in cages). Conversely, organic eggs presented the weakest eggshells (breaking strength of 34.19 N vs. 47.05 N in cages) and a less favourable lipid profile regarding atherogenicity (AI: 0.411) and thrombogenicity (TI: 3.455) indices. Crucially, organic eggs contained significantly higher levels of lead (0.361 mg/kg) compared to indoor systems (0.041 mg/kg in barn and 0.102 mg/kg in cages), highlighting their susceptibility to environmental pollution. Cage and barn eggs were associated with higher chemical safety and shell strength but demonstrated a lower overall bioactive value. Ultimately, the choice of table eggs may involve a trade-off between the health-promoting benefits of extensive systems and the potential risks of heavy metal contamination, emphasising the need for integrated food safety management.

Certification schemes are increasingly positioned as institutional mechanisms that may support sustainable food markets, yet the joint longitudinal relationship between certified production penetration, certified supply-chain infrastructure and organic market uptake remains insufficiently integrated in European-scale empirical analyses. This study examined how certified organic production, supply-chain infrastructure, and market uptake co-evolved across Europe. A country–year panel of 995 observations from 41 European countries (2000–2024) was assembled from FiBL statistics and analysed using descriptive trend analysis, Spearman correlations, linear mixed-effects models with country random intercepts, and k-means clustering. Certified organic systems expanded substantially: mean organic farmland share rose from 2.80% to 9.73%, retail sales share from 1.42% to 4.49%, and per capita consumption from €25.82 to €87.60. Organic area share remained positively associated with organic retail sales share after adjustment for PPP-adjusted GDP per capita (β = 1.247, p < 0.001), with a similar pattern for the secondary per capita consumption outcome (β = 36.426, p < 0.001). Certified supply-chain actors were strongly intercorrelated (producers–processors ρ = 0.824). Organic farmland share was the most consistent correlate of market uptake, including after adjustment for GDP per capita, whereas absolute operator counts and supply-chain infrastructure indicators were more difficult to interpret independently because of collinearity. A four-cluster typology showed that countries with the largest certified production bases were not those with the most mature markets. These findings are consistent with the interpretation that certification penetration may support market development by providing credible institutional signals, but trust creation, information asymmetry reduction, and legitimacy were not directly measured. The results, therefore, indicate an association between certification-system development and market uptake, while also showing that production expansion and market maturity are distinct dimensions of the sustainability transition.

Selecting suitable agricultural land is critical for food security and sustainable development, particularly in arid regions facing resource scarcity and environmental degradation. This study assesses agricultural land suitability in Sohag governorate, Egypt, using a hybrid Geographic Information System (GIS), Fuzzy Analytical Hierarchy Process (FAHP) and geostatistical approach. Thirty-four representative soil profiles were morphologically described and analyzed for ten physical (slope, depth, erosion, texture, stoniness, drainage) and chemical (EC, pH, CaCO₃, organic matter) criteria, weighted using both the Analytical Hierarchy Process (AHP) and FAHP. Geostatistical analysis characterized the spatial variability in soil properties across the study area. The two suitability maps were validated using Receiver Operating Characteristic (ROC) curves and Kappa statistics: the FAHP achieved higher prediction accuracy (AUC = 0.83, Kappa = 0.91) than the AHP (AUC = 0.81, Kappa = 0.88). The AHP-based map classified 40% (1154.92 km²) as moderately suitable (S2), 33% (952.81 km²) as marginally suitable (S3), and 27% (779.57 km²) as unsuitable (N); the FAHP-based map classified 42% (1212.67 km²) as S2, 30% (866.19 km²) as S3, and 28% (808.44 km²) as N. The proposed framework may serve as a reference for similar arid environments and support progress toward Sustainable Development Goals 2, 6, 8, 9, 11, 13 and 15, conditional on local soil, water, climate and management conditions.

Urban air pollution remains a major public health concern, with road traffic representing one of the dominant sources of particulate matter and volatile organic compounds in growing cities. This study evaluates the level of chemical air pollution in Alba-Iulia municipality (Romania) through two measurement campaigns (May 2025 and October 2025), carried out at 26 and 19 points, respectively, selected based on traffic intensity and population vulnerability criteria (schools, kindergartens, hospitals, and the food market). Measurements targeted PM_2.5, PM₁₀, total volatile organic compounds (TVOC) and formaldehyde (HCHO), as well as carbon dioxide (CO₂), correlated with road traffic intensity. Statistical analysis revealed significant differences between the two seasons for PM_2.5, PM₁₀, and CO₂ (p < 0.01), as well as a strong correlation between particulate matter concentrations and vehicle counts (r = 0.60–0.95), consistent with road traffic being an important local contributor to particulate matter, though correlation alone cannot establish source dominance in a strict causal sense. A multiple regression controlling for both traffic and season explained over 73% of the variance in PM_2.5 and PM₁₀ and showed that traffic and season each contribute independently to particulate levels. Both mean PM_2.5 and PM₁₀ exceeded WHO and EU limit values in both campaigns, and the low-cost sensor over-read absolute concentrations by roughly 2–4× relative to the official monitoring network, so absolute values should be treated as orientative. Despite this bias, the consistent spatial and seasonal patterns show that portable low-cost sensors can reliably rank exposure hotspots and support the targeting of traffic-mitigation measures, such as selective catalytic reduction (SCR) systems, in medium-sized cities that lack dense reference monitoring networks.

Tropical fruit processing generates substantial quantities of seed-derived by-products that remain underutilized despite their potential as sources of bioactive compounds, proteins, lipids, dietary fiber, and polysaccharides. This critical narrative review evaluates their conversion into functional ingredients by integrating compositional variability, pretreatment and extraction, antinutritional-factor mitigation, structural characterization, food-system performance, storage stability, gastrointestinal behavior, safety, regulatory readiness, and scale-up feasibility. Direct evidence was distinguished from mechanistic support derived from non-target botanical matrices. An exploratory semantic clustering of 100 PubMed records published in 2024–2026 was conducted with Carrot2 to organize application-oriented themes and identify knowledge gaps; its output was interpreted as a thematic aid rather than a quantitative trend analysis. The review also examines biochar production from exhausted or non-food-grade seed biomass as a complementary cascading route, considering feedstock properties, thermochemical conditions, physicochemical quality, safety, application performance, and techno-economic constraints. The main contribution is an evidence-derived multi-stage decision framework linking ingredient validation with residual-biomass valorization. Current evidence supports promising nutritional and technological applications but remains heterogeneous and predominantly laboratory-based, with limited standardized comparisons, in vivo validation, regulatory assessment, and pilot-scale studies. Advancing these materials therefore requires application-specific, safety-oriented, and economically realistic validation within circular bioeconomy systems. Full article

Agriculture plays a key role in global food production, whereas organic waste management remains an important environmental challenge. Organic residue-derived compost represents a sustainable strategy for nutrient recycling, soil fertility improvement, and reduced reliance on synthetic fertilizers in horticultural systems. This study systematically reviewed the scientific literature on the application of compost in cherry tomato (Solanum lycopersicum var. cerasiforme) cultivation to evaluate its effects on agronomic performance and production systems. A database search from 2004 to July 2025 identified 86 studies that met the predefined eligibility criteria. The analysis showed an increasing trend in research over the last two decades, with publications peaking in 2021. Most studies were conducted in Latin America, particularly in Colombia, Mexico, and Brazil, highlighting the relevance of the cherry tomato crop. The application of compost was associated with improved plant growth, nutrient availability, and crop productivity. The production cycles ranged from 37 to 220 days, with shorter cycles commonly observed in tropical environments. Rice husk compost is among the most frequently used organic amendments. Overall, compost represents an effective strategy to enhance agronomic performance and promote sustainable cherry tomato production worldwide. Full article

Microplastics have emerged as one of the most widespread and significant environmental pollutants, occurring in aquatic and terrestrial ecosystems, the atmosphere, food, and living organisms. Given the rapid expansion of research in this field, a comprehensive synthesis of the current state of knowledge is warranted. The aim of this study was to map the available literature on microplastics, with particular emphasis on advanced identification and characterisation techniques, environmental transport and transformation processes, life cycle assessment, and remediation strategies. This scoping review was conducted in accordance with the PRISMA-ScR guidelines using publications retrieved from the PubMed, Scopus, Web of Science, and Google Scholar databases. The analysis demonstrated substantial advances in analytical methodologies, particularly spectroscopic and microscopic techniques, enabling the accurate characterisation of micro- and nanoplastic particles. It also highlighted the complex mechanisms governing the transport and transformation of microplastics across environmental compartments, as well as their important role as vectors of chemical contaminants. From a systems perspective, life cycle assessment of plastics was identified as an essential tool for evaluating their environmental impacts. Current mitigation approaches, including filtration technologies, wastewater treatment processes, and biological remediation strategies, were also reviewed, along with their limitations and potential for future development. This review identifies the lack of standardised analytical methodologies and the limited capability for nanoplastics detection as two major challenges hindering the global harmonisation of microplastics research. The findings emphasise the need for further interdisciplinary studies and the implementation of integrated strategies encompassing the entire life cycle of plastics to effectively reduce microplastics emissions and mitigate their environmental impacts.

For decades, industrial trans fatty acids (iTFAs) have remained a critical focus of the scientific community, the food industry, and regulatory authorities because of their well-established role in the development of cardiovascular diseases, metabolic disorders, and chronic systemic inflammation. Rather than providing a descriptive overview, this review critically synthesizes current evidence on the elimination of industrial TFAs by integrating health, technological, regulatory, and sustainability perspectives into a comprehensive interdisciplinary analysis. The review outlines the biochemical characteristics and dietary sources of trans fatty acid isomers, highlighting the continuing scientific debate regarding the differential health effects of industrially produced and naturally occurring ruminant-derived TFAs. It also examines the evolution of scientific evidence that led to major regulatory actions by international organizations, including the World Health Organization (WHO) and the European Commission, resulting in legally binding restrictions that have substantially reduced industrial TFA intake and improved public health. Particular emphasis is placed on the critical assessment of current fat reformulation strategies, considering not only their technological functionality but also their nutritional quality, long-term metabolic implications, and contribution to sustainable food systems. Full hydrogenation, fractionation, chemical and enzymatic interesterification, and oleogelation are comparatively evaluated with respect to their advantages, limitations, and potential technological, nutritional, and environmental trade-offs. In addition, lipid microencapsulation is discussed as an emerging strategy for protecting oxidation-sensitive polyunsaturated fatty acids (PUFAs), thereby facilitating their incorporation into functional foods while maintaining nutritional quality. Unlike previous reviews that primarily focus on health outcomes or individual processing technologies, this review systematically integrates the sustainability dimensions of alternative fat modification approaches, including resource efficiency, energy consumption, clean label product development, and circular economy principles. Furthermore, it identifies current knowledge gaps related to the long-term metabolic safety, industrial scalability, and environmental performance of emerging lipid technologies. By combining these complementary perspectives, the review provides a comprehensive interdisciplinary synthesis that supports evidence-based fat reformulation and offers practical guidance for researchers, food manufacturers, and policy makers seeking to develop safer, nutritionally improved, technologically functional, and environmentally sustainable lipid systems.
