Summary: | The invention relates to a preparation method of yak milk casein antihypertensive peptide. The method comprises main technical schemes as follows: (1) dissolving yak milk casein; (2) adding trypsin for hydrolysis; (3) inactivating the trypsin; (4) precipitating casein; (5) centrifuging and removing the precipitant; (6) performing ultra-filtration; (7) performing nano-filtration; and (8) performing spray drying. Raw materials for the method provided by the invention are unique; the process is scientific and reasonable, simple and feasible; the product is the casein antihypertensive peptide with rather high purity with the ACE (angiotensin converting enzyme) inhibition activity higher than 70%; the product is safe and free from toxic side effects, has nutritional and assistant medical treatment functions, and can be used as an additive widely applied in the fields of food, healthcare products and medicines and the like. |
