To provide a food material containing a material inhibiting angiotensin converting enzyme by discovering a safe material capable of inhibiting the elevation of blood pressure by effectively inhibiting an angiotensin converting enzyme from a food material, making the structure of the inhibiting material clear, and developing a simple method for concentrating the material.
This material inhibiting the angiotensin converting enzyme consists essentially of the eluted adsorbed component obtained by subjecting a soybean protein solution eluted from a raw material soybean by a water extraction treatment to a degradation treatment with a proteolytic enzyme, bringing the treated product into contact with a reversed phase distribution-type resin, and eluting the component adsorbed on the reverse phase distribution-type resin.
