Special Issue Information

Dear Colleagues,

Global food production must increase up to 70% by 2050 to meet the demands of the growing world population (FAO. Global agriculture towards 2050, Rome) yet, currently, over one-third of food produced globally is lost or wasted (FAO. Global Food Losses and Food Waste: Extent, Causes and Prevention, Rome). Food loss determines the decrease in edible food mass along the food chain, including the production, post-harvest, and processing levels. Reducing food wastage represents a neglected opportunity, particularly in developing countries, to improve food security and availability. Tackling the issue of food loss and waste can generate a triple win: (1) reductions can save money for farmers and companies, improving the workers’ profit and household economy; (2) wasting less food means feeding more people, and, finally, (3) waste reductions can alleviate pressure on the climate, as well as on water and land use, contributing to resilience to climate change.

In this Special Issue, we invite submissions of original research, review articles, and opinions on new strategies fostering an ethical food industry through the development of optimized production processes, innovative packaging solutions, extension of shelf life, and the valorisation of food by-products.

Hybrid and plant-based products are an emerging trend in food science. This study aimed to develop three patty prototypes (meat, hybrid, and plant-based) enhanced with vegetable fat replacement and broccoli extract using a soy allergen-free protein matrix treated with high hydrostatic pressure (HHP) and sous vide cooking to create sustainable and nutritious burger alternatives. The samples were evaluated for microbiological safety, proximal composition, physicochemical properties, sensory characteristics, and carbon footprint. The key findings revealed that the plant-based patties had the smallest carbon footprint (0.12 kg CO2e), followed by the hybrid patties (0.87 kg CO2e) and the meat patties (1.62 kg CO2e). The hybrid patties showed increased hardness, cohesiveness, gumminess, and chewiness compared to the meat patties after sous vide treatment. This improvement likely results from synergies between the meat and plant proteins. Regarding the treatments, in all the samples, the highest hardness was observed after the combined HHP and sous vide treatment, an interesting consideration for future prototypes. Sensory analysis indicated that the plant-based and hybrid samples maintained appealing visual and odour characteristics through the treatments, while the meat patties lost the evaluator’s acceptance. Although further improvements in sensory attributes are needed, hybrid patties offer a promising balance of improved texture and intermediate carbon footprint, making them a viable alternative as sustainable, nutritious patties.

The cultivation of soybean is being expanded in traditional areas cultivated with rice, called the lowlands. However, soil characteristics are different from those in the highlands, which influences the exportation of nutrients to the grains. Therefore, this study aimed to determine the physical-chemical and technological characteristics of soybean grains harvested in lowlands in Brazil. Two-year crops (2021/22 and 2022/23) were used with two types of soil preparation (scarified and non-scarified) and six cover crop treatments (oats, clover, ryegrass, fallow, ryegrass + oats, and ryegrass + clover). The influence of these treatments was evaluated in terms of the grain yield, oil and protein contents, oil composition, quality indices (acidity, peroxide, iodine, and saponification), and contents of ash, carbohydrates, and micro- and macronutrients. Grain yield achieved an average of 3829.8 kg ha−1. Soil scarification positively influenced grain yield and contributed to higher protein and oil contents, with maximum values of 32.7 wt% and 27.6 wt%, respectively. The main fatty acids in oil were oleic acid (22.13 ± 1.48–26.32 ± 0.98%) and linoleic acid (36.32 ± 1.57–52.18 ± 1.58%). The macronutrients phosphorus (5.12 ± 0.39–5.79 ± 0.37 kg ton−1), calcium (2.79 ± 0.19–3.05 ± 0.18 kg ton−1), magnesium (2.37 ± 0.14–2.57 ± 0.13 kg ton−1), and sulfur (2.85 ± 0.18–3.19 ± 0.20 kg ton−1), and the micronutrients copper (9.73 ± 1.42–11.68 ± 1.07 g ton−1), iron (111.42 ± 6.86–122.02 ± 5.00 g ton−1), and manganese (43.58 ± 3.34–47.08 ± 2.74 g ton−1) were in agreement with the values reached in the highlands. For potassium (18.87 ± 0.38–29.29 ± 1.44 kg ton−1) and zinc (30.02 ± 2.45–38.00 ± 1.03 g ton−1), soil scarification allows higher levels of absorption. The use of ryegrass as a cover crop allows higher levels of nitrogen absorption, reaching up to 44.93 ± 2.74 kg ton−1. Regarding the acidity (0.19–0.52%), peroxide (9.64–16.39 mEq O2 kg−1), iodine (85.34–91.91 mg KI g−1), and saponification (182.33–203.74 mg KOH g−1) indices of the oil, all values were obtained in accordance with the scientific literature. The conclusions of this study indicate that it is possible to cultivate soybean in lowlands after developing the proper soil preparation. Consequently, the yields are increased, and grains will benefit from higher protein and oil contents, enhancing soybean quality for commercialization. Full article

Rapid population growth, climate change, and resource depletion pose significant challenges to global food production, demanding sustainable solutions. A Life-Cycle Assessment (LCA) provides a structured framework for evaluating the environmental impact of food systems throughout their entire life cycle. This review examines how an LCA can be integrated with circular economy principles to address sustainability challenges, optimize resource use, and minimize waste in food and alcoholic beverage production. A systematic review of LCA applications in the agri-food sector was conducted, analyzing studies published across different regions. The selection criteria included relevance to circular economy strategies, waste valorization approaches, and assessing environmental impacts using LCA methodologies. The analysis explores explicitly the synergy between food and wine production within the broader agri-food system, considering shared sustainability challenges and opportunities for resource optimization. Key methodologies include cradle-to-grave assessments and the evaluation of waste-to-resource technologies. The findings demonstrate that LCA effectively identifies critical environmental hotspots, enabling the implementation of eco-design and resource recovery practices. Circular strategies, such as the use of renewable energy, precision agriculture, and nutrient recovery, significantly enhance sustainability. However, gaps remain in accounting for social and regional variability, as well as in integrating advanced technologies. When combined with circular economy principles, LCA provides actionable insights for policy development and sustainable practices. Advancing LCA methodologies and fostering multi-stakeholder collaboration are essential for creating resilient and environmentally responsible agri-food systems. Full article
