Process for the preparation of a protein hydrolyzate with ACE-inhibiting tryptophan-containing dipeptides

摘要

A process for producing a protein hydrolyzate with ACE-inhibiting tryptophan-containing dipeptides by enzymatic hydrolysis of a proteinaceous substrate in at least two treatment steps with different proteolytic enzymes, wherein the proteinaceous substrate contains lysozyme, alpha-lactalbumin, beta-lactoglobulin, casein, ovalbumin and / or lactoferrin, characterized in that in a treatment step, an enzymatic hydrolysis of the proteinaceous substrate with thermolysin and in a further treatment step, an enzymatic hydrolysis of the proteinaceous substrate is carried out with chymotrypsin.
