摘要：

Millet protein was u s e d as raw material to prepare food-derived peptides with antioxidant activity andan- giotensin transferase (ACE) inhibitory aetivity. Alkaline protease, neutral protease and flavor protease were used to hydrolyze millet protein. Three components with molecular weight < 3, 3 - 1 0 ku and > 10 ku were obtained from the hydrolysate obtained by alkaline protease for 4 h, and their antioxidant and ACE inhibitory activities were determined. The results showed that the polypeptides with molecular weight < 3 ku obtained from the hydrolysate obtained by alkaline protease for 4 h after ultrafiltration had the highest antioxidant activity and ACE inhibitory activity, with DPPH scavenging capacity of 38.44%, ABTS free radical scavenging capacity of 81.62%, hydroxyl radical scavenging capacity of 68.49%. The inhibitory activity of ACE was 87.53%. The polypeptides obtained by this method have low molecular weight, high content of functional amino acids, and have good antioxidant and ACE inhibitory activities, which provide a basic for the development of antioxidant peptides and ACE inhibitory peptides, and provide a theoretical basis for the future industrial development. © 2023 Chinese Institute of Food Science and Technology.
