Bioactive Proteins and Peptides from Agro-Industrial Waste

Abstract

Agro-industrial wastes are known as a valuable source of various bioactive compounds that provide a wide range of beneficial effects on human health. These wastes generated from the agricultural industry contain a relatively high amount of proteins, which are considered a promising source of bioactive proteins/peptides. Recently, agro-industrial wastes with rich protein content have been studied regarding the recovery technique, the extraction of bioactive proteins/peptides, the determination of biological and techno-functional properties, and their application in food, pharmaceutical, and cosmetics. The health-promoting effects and techno-functional properties of bioactive proteins/peptides are highly associated with their amino acid sequence, molecular weight, and conformational and surface properties. Likewise, these physiological properties of bioactive proteins/peptides are affected by the extraction method. Green-technology-based extraction techniques have been recently utilized for the production of bioactive proteins/peptides. Furthermore, the application of bioactive proteins/peptides in food formulations as innovative future foods have been gaining much attention in the food industry.
