Objective To obtain angiotensin-converting-enzyme （ACE） inhibitor from the hydrolyzates of rice bran protein. Methods The deposition method of adjusting isoelectric point was adapted to get rice bran protein. The protein was hydrolyzed with pepsin and trypsin successively. The hydrolyzed products were separated to many groups by gel chromatography and ACE inhibitor activity of each group was tested, One group with high inhibitor activity was further separated and purified by ion exchange chromatography. Results The molecular weight of ACE inh...
