Obtaining and Study of Peptide Compositions Based on Hydrolysates of Collagen-Containing Fish Raw Materials

Experimental studies of fish cutting waste—scales and skin were carried out, their general biochemical composition was studied, a high content collagen established, elastin noted, which accounted for 76–86% the protein mass. Processes hydrolysis secondary raw materials have been developed: scales skin. Technological schemes developed influence conditions thermal, enzymatic, enzymatic-thermal, electrochemical on amino acid molecular weight distribution (MWD) antioxidant activity peptides proteins in obtained hydrolysates has studied. It established that enzymatic enzymatic-thermal method using enzyme Alcalase 2.5 L cod, trout herring made it possible to obtain with 80–90%. At same time, 91–98% from 62%, 74% 82.5% electrochemically trout, herring, respectively, account share low-molecular less than 10 kDa. The prospects use functional foods oil-containing products are noted.
