To get the structure and function information about ACEI（angiotensin coverting enzyme） inhibitors derived from food protein. The present study prepared ACEI inhibitors from rice bran. The method of isoelectric point （PI） precipitation was adopted to obtain rice bran protein, which was hydrolyzed by pepsin, trypsin, and papain individually or jointly. The hydrolyzed products were separated according to the differences of molecular weights by Sephadex G-15 gel chromatogram. The components with the highest ACE inhibitor activity measured by FA...
