[Bioactive proteins and peptides: current state and new trends of practical application in the food industry and feed...

Proteins and polypeptides play a key role in the life of a human body. Scientific and practical interest to the natural proteinaceous substances could be explained by the diversity of their functions in metabolic processes. Biologically active substances of the protein origin have a rich history of applications in different sectors of the economy. In this case, the close relationship is observed between food industry, biomedicine and fodder production, because efficient conversion of feed protein in productive agricultural animals provides, as a result, the required level of metabolism in a human, as the main consumer of final products derived from these animals. Obviously, for normal growth, development and resistance to infectious agents, both people and farm animals need a constant consumption of L-amino acids in certain proportions and in available for absorption form. This review considers the bioactive polypeptides used in nutrition and food industry, main trends and practical approaches to generating protein products with the desired characteristics.
