The invention belongs to the technical field of food-derived protein deep processing, and in particular relates to a sesame polypeptide. The polypeptide consists of 8 amino acids, and its sequence is: Glu-Ala-Cys-Ile-Gln-Ala-Cys-Lys (EACIQACK). The sesame polypeptide of the present invention can be obtained after separation and purification by enzymatic hydrolysis of sesame protein, or can be artificially synthesized by chemical solid-phase synthesis method. By measuring the DPPH scavenging ability, ABTS scavenging ability, total antioxidant capacity (FRAP) and ACE inhibitory ability, the present invention finds that the polypeptide has strong antioxidant and blood pressure lowering activities, and can be used as a functional active ingredient for preparing medicines, health products, Food, nutritional supplements, feed, cosmetics, daily chemical products and other fields have broad market prospects. |
