In order to produce a peptide having an angiotensin converting enzyme material activity, a hydrolase different from animal protein, for example, fish, chicken or pig, separation and purification methods are used. Five novel peptides that can be used as angiotensin converting enzyme inhibitors are disclosed. A method for producing a product having angiotensin converting enzyme inhibitory activity is also disclosed, which method comprises the following steps: (a) adding a protein hydrolase for reaction to a solution of chicken lees, (b) after the reaction of step (a) Separating the chicken lees and liquid, collecting the separated liquid, and (c) drying the liquid obtained from step (b) to obtain the product.
