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
