The invention discloses five novel peptides which can be used as
angiotensin converting enzyme inhibitor. The subject invention also
discloses a process for the preparation of the products having angiotensin
converting enzyme inhibitory activity, which comprises the following
steps:
(a) adding protein hydrolase to the solution of chicken residues for
reaction;
(b) separating the chicken residues and liquid after the reaction of step
(a) and collecting the separated liquid; and
(c) drying the liquid obtained from step (b) to obtain the products.
