酶解桃仁分离蛋白制备肾素和ACE 双重抑制肽的工艺研究
Study on enzymatic hydrolysis conditions for the preparation of dual rennin and ACE inhibitory peptide from peach kernel protein isolate
摘要
Abstract
The preparation of dual rennin and angiotensin‐I‐converting enzyme (ACE) inhibi‐tory peptides from peach kernel protein isolate with Alcalase 2 .4 L was investigated .ACE in‐hibitory rate in vitro and renin inhibitory rate in vitro were investigated with respect to hy‐drolysis parameters including temperature ,pH ,substrate concentration and enzyme dosage . As a result ,the optimum conditions for enzymatic preparation of dual rennin and ACE inhib‐itory peptides from peach kernel protein isolate were found to be hydrolysis at pH 8 .02 ,tem‐perature of 50 .6 ℃ and enzyme dosage of 3 .06% .Under these conditions ,the prepared pep‐tides showed an ACE inhibitory rate of 69 .03% ,renin inhibitory rate of 57 .61% .关键词
