FIELD: chemistry.
SUBSTANCE: method of obtaining a yeast extract involves treating Saccharomyces cerevisiae yeast cells with purified phospholipase A and separating the yeast extract from treated yeast cells. Yeast cells undergo proteolysis during treatment with phospholipase. Treatment with phospholipase is carried out at pH 2-10, and the amount of phospholipase ranges from 0.001 to 1 mg enzymatic protein/g dry substance. Yeast extract output is equal to 68.8%, protein output is equal to 67.4% and degree of hydrolysis is equal to 71.8%.
EFFECT: method enables to obtain an end product with high output, protein content and degree of hydrolysis.
