Special Issue Information

Dear Colleagues,

A sustainable food economy creates new social, economic, and environmental goals for food producers. Today, food should not only fulfill nutritional requirements but improve the well-being of populations and provide deficient nutrients. A great challenge is determining how to develop processing operations that save natural resources, with limited environmental impact, and reduce waste production.

This requires multi-directional actions in the entire food production chain, including searching for alternative raw materials, replacing conventional processes with less energy-consuming ones, or developing the so-called “clean technologies” with lower impact on environment. Another important aspect is also obtaining high-quality and extending the shelf-life of products with a lower degree of processing, and reducing and re-directing valuable compounds from the waste stream. The strategy of sustainable development also includes proper production management, reduction in losses and waste management, as well as searching for opportunities to reuse them. A sustainable approach to food production, in view of the limited availability of water and high-resource intensity of animal production, also stimulates the development of new food products, e.g., plant-based food or alternative sources of protein.

Considering all the aspects mentioned above, we would like to propose a Special Issue entitled “Emerging and Modern Approaches for Sustainable Food Production and Waste Management”. The aim of this Special Issue is to collect creative research papers presenting original research results,  or to show review papers highlighting recent achievements in sustainable food production.

The agro-food industry produces large amounts of secondary by-products, which can act as a source of bio-active ingredients. These ingredients can be used as valuable additives to support the sustainable circular economy concept. This study aimed to analyze the potential application of horseradish and grapevine leaves in the fermentation process of low-salt pickled cucumbers to improve their sensory and functional properties. The pour plate technique, RT-qPCR, HPLC, and a nine-point hedonic scale test with penalty analysis were used to analyze the traditionally fermented product. The research showed that the addition of both horseradish and grapevine leaves did not negatively affect the kinetics of fermentation and had a positive effect on the overall desirability. Moreover, they contributed to an increase in the concentration of antioxidant compounds, namely gallic acid (grape leaves) and ellagic acid (grapevine and horseradish leaves). Bacterial metabiome analysis showed the positive effect of all analyzed additives on an increase in the relative expression of genes responsible for the synthesis of selected bacteriocins (plantaricin and acidocin). Research results indicated a high potential for sustainable use of by-products (horseradish and grapevine leaves) in the production of traditional low-salt fermented cucumbers with high health-promoting potential.

This study evaluated different hybrid drying modes, combining traditional convective drying with microwave radiation and airborne ultrasound for the dehydration of green leafy vegetables. The central composite design method was used to analyze the impact of microwave and ultrasonic waves on kinetics, energy consumption, and various quality parameters, like color, ascorbic acid, polyphenol, carotenoid, and chlorophyll content in Brassica oleracea, var. acephala. The results of the applied experimental design, i.e., the surface response methodology, showed that the application of microwaves and ultrasound decreased the drying time considerably and enhanced the moisture evaporation from the kale leaves, significantly improving the drying rate and energy efficiency. The drying rate increase demonstrated varying results with changes in air temperature. Specifically, ultrasound resulted in a 69–100% increase, microwaves in a 430–698% increase, and a combination of ultrasound and microwaves in a 463–950% increase at 70 and 50 °C, respectively. Specific energy consumption decreased by 42–51% for ultrasound, 80–87% for microwaves, and 82–90% for ultrasound and microwaves at 70 and 50 °C, respectively. The drying parameters were also found to be better at a higher temperature, but the increase in the drying rate caused by microwaves and ultrasound was notably lower. Moreover, the analysis of the key kinetic parameters and material qualities led to the conclusion that the synergistic action of microwave- and ultrasound-assisted convection contributes to better drying effectiveness and product quality, demonstrating greater retention of vitamin C, phenolics, and natural dyes of up to 90%.
