Abstract: Yak milk casein was hydrolyzed by six commercially available proteases whereas, the hydrolysates were assayed for the inhibitory activity of angiotensin-I converting enzyme (ACE). Based on the results of the ACE inhibitory activity, the protein hydrolysis degree and the protein recovery, the protease C is chosen to produce ACE inhibitory peptides from yak milk casein.
