详细
To perform hydrolysis with the enzyme complex from the hepatopancreas of the Kamchatka crab, a protein mixture was isolated from soybean meal by extraction at alkaline pH values. Extractable low-molecular impurities were removed by ultrafiltration and precipitation of proteins with alcohol. The amino acid composition of the obtained protein extract turned out to be similar to the composition of the fish meal traditionally used in the production of fish feeds. Analysis of the products of fermentolysis by DDS-electrophoresis, HPLC, and mass spectrometry showed a high degree of hydrolysis of soybean proteins. Depending on the time of fermentolysis, the hydrolysates contained up to 60% (18 h of hydrolysis) of free amino acids (the fraction of the weight of the hydrolyzed protein mixture) and short peptides (2–20 amino acid residues).
