Abstract: The reductive antioxidative and hydroxyl radicals scavenging activities of the soybean peptides prepared with enzymolysis and ultrafiltration were studied in this paper. The results showed that the antioxidative activities of the soybean peptides were stronger when the concentrations were higher, and the soybean peptides had powerful scavenging activity on hydroxyl radicals within certain concentration range. In addition, the soybean peptides showed no pro - oxidating effect.

Key words: Soybean peptides , Antioxidation , Hydroxyl radical , Scavenging effect
