Abstract
In the study, two Lactobacillus cultures i.e. L. casei (NK9) and L. fermentum (LF) were studied for their proteolytic activity, di and tripeptidase activity, ACE-inhibitory activity and peptides production under optimized growth condition from fermented goat milk (Capra aegagrus hircus). NK9 and LF were found to be a strong proteolytic culture with 2.0% rate of inoculation after 48 h. LF (10 kDa retentate) produced maximum peptides among all the retentates of the fermented goat milk. Goat milk fermented with NK9 (10 kDa permeates) exhibited peptide sequence i.e. AFPEHK which had ACE inhibitory activity, matched with goat milk protein databases of AHTPDB. However, L. casei (NK9) and L. fermentum (LF) could be explored for the production of ACE inhibitory peptides from fermented goat milk.
