Antihypertensive casein protein hydrolysate and manufacturing method thereof

摘要

PURPOSE: Provided is a process of preparing casein protein hydrolysate which is not decomposed by angiotensin converting enzyme while having excellent inhibitory activity on angiotensin converting enzyme, by using an enzyme which acts in neutrality, thereby increasing productivity and reducing the cost of production. The product is convenient to eat and can be used as a protein supply source. CONSTITUTION: A protease is added to an aqueous casein protein solution in the amount of 0.1 to 3% and reacts at 30 to 50deg.C and a pH of 6 to 9 for 4 to 48hr. The protease is one or more selected from the group consisting of MP(Aspergillus melleus), Promod 192(derived from Aspergillus), Pescalase(Bacillus licheniformis), Protamex(derived from Bacillus) to produce hydrolyzed casein vegetable protein which lowers a blood pressure and has a molecular weight of 773 daltons.
