METHOD FOR PRODUCTION OF PEPTIDE OR PROTEIN PRODUCT REINFORCED BY COVALENTLY BONDING AMINO ACID

摘要

A process for preparing peptide and/or protein products enriched with covalently bound amino acids comprises the addition of the amino acid (which may be in an aligopeptide) to be incorporated in the form of an active derivative to the reaction mixture containing the protein(s) or peptide(s) to be enriched as substrate(s), where enzymatic peptide modification is accomplished through catalysis by means of protease enzyme, and the product(s) obtained and the excess of the amino acid derivative are removed from the reaction mixture. The process renders possible the improvement of the food-value of proteins of some foods and dietetic products.
