The object is to provide an enzymatic collagen hydrolysate or a peptide which has an ACE (angiotensin converting enzyme)-inhibiting activity (i.e., an anti-hypertensive activity)/a blood vessel protection activity. Disclosed is a protease hydrolysate of a chicken or porcine collagen, which has an anti-hypertensive activity and/or a blood vessel protection activity, particularly a peptide which is a protease hydrolysate of a chicken or porcine collagen and has a molecular weight of 3000 or less. The protease hydrolysate of a chicken or porcine collagen or the peptide has an ACE-inhibiting activity and/or a blood vessel protection activity, and therefore is useful as a functional food having an anti-hypertensive activity and/or a blood vessel protection activity or the like. |
