Special Issue Information

Dear Colleagues,

Agro-industrial processing generates millions of tons of byproducts and waste annually during the collection, storage, transport, and process of raw materials. There is a wide variety of bioactives found in residues derived from the cultivation and processing of agricultural products. Any part of plants, such as husks, seeds, leaves, roots, and stems, can be considered a source of bioactive compounds, and their valorization is a must for global food sustainability. There is a rising demand in maintaining human wellness through nutrition which has greatly promoted the interest in food bioactive compounds all over the world. Food bioactives such as polyphenols, phytochemicals, saponins, dietary fiber, proteins, peptides, polysaccharides, and lipids can be extracted from agro-industrial byproducts and wastes. These bioactives possess several biological properties, such as antioxidant, anticancer, antidiabetic, and anti-inflammatory activities which are utilized in the food industry, biomedical zone, and energy sector. If the procedures for extracting these molecules are economically viable, increased attention will be drawn toward food waste as a source. The feasibility of realizing the potential economic benefits of agricultural byproducts and wastes could be enhanced by the application of efficient and environmentally friendly extraction techniques.

Convective drying is the most widely used technique to stabilize by-products in the food industry, permitting later processing. A thorough knowledge of the relationship between moisture content and water activity allows the optimization of not only drying operations, but the settings of storage conditions. Thus, the thermodynamic properties of pomegranate peels were determined during the desorption process. Experimental sorption isotherms at 20, 30, 40 and 50 °C showed type II Brunauer behavior. Eight different theoretical and empirical equations were fitted to the experimental results; the theoretical GAB model and the empirical Peleg model were the ones that achieved the best fit (R2 of 0.9554 and 0.974, respectively). The Clausius–Clapeyron equation and the enthalpy–entropy compensation theory were used to determine the thermodynamic parameters. The isosteric heat determined from the sorption isotherms decreased regularly as the equilibrium moisture content rose (from 8423.9 J/mol at 0.11 kgH2O/kg d.m. to 3837.7 J/mol at 0.2 kgH2O/kg d.m.). A linear compensation was observed between enthalpy and entropy, which indicated an enthalpy-controlled sorption process. Full article

Management of waste and use of winemaking by-products plays an important role in the development of new ingredients, especially with antiviral properties. Although the richness of bioactive compounds from wine waste is known, less is known about potential antiviral action. Bioactive compounds and health-enhancing effects of winery by-products make them potential candidates for use in antiviral ingredients. The design of new formulations by using nano-microencapsulation techniques will be necessary to successfully control diseases produced by viruses. Outcomes about the use of winery by-products, bioactive compounds found in winery wastes, green extraction techniques to concentrate these compounds, and development of formulations to obtain new ingredients were extracted from research around the world to be discussed and updated in this manuscript. The evidence collected in this review aims to encourage transfer of in vitro and in vivo knowledge to a new step for the development of antiviral and treatments. Full article
