摘要:

对瑞士乳杆菌发酵乳清蛋白产生血管紧张素转化酶(angiotensin converting enzyme,ACE)抑制肽的发酵条件进行探讨。通过单因素分析和响应面试验设计,确定发酵乳清蛋白制备ACE抑制肽的最佳工艺条件:发酵时间为17.52h,发酵温度为37.07℃,乳清质量浓度为114.1g/L,其ACE抑制率可达89.337%。

关键词: 瑞士乳杆菌, 发酵乳清蛋白, ACE抑制肽, 响应面法

Abstract:

In this work, the effect of fermentation conditions on the preparation of ACE (angiotensin converting enzyme) inhibitory peptides from whey protein fermented by Lactobacillus helveticus was investigated. The optimal fermentation conditions were determined using single factor method combined with response surface methodology as follows: 17.52 h of fermentation time, 37.07 ℃ of fermentation temperature, and 114.1 g/L whey protein. The inhibitory activity of anti-ACE peptides obtained under the optimal conditions was up to 89.337%.

Key words: Lactobacillus helveticus, whey protein fermentation, ACE inhibitory peptide, response surface methodology
