PROBLEM TO BE SOLVED: To clarify components of ethanol-soluble components in a solution obtained by removing an undegraded polymer fraction rich in hydrophobic amino acids in a treatment solution (decomposition solution) by treatment with soybean protein protease, The purpose is to clarify the benefits. A peptide composition prepared from an aqueous solution obtained by treating a soy protein raw material with a protease and removing an undegraded polymer fraction rich in insoluble hydrophobic amino acids has angiotensin I converting enzyme (ACE) inhibitory activity. And has a suppressive effect on the reduction of human erythrocyte deformability, and they are used as a medicinal composition, used as a raw material for health foods and pharmaceuticals, and have a large use for soybeans.
