Abstract : Antioxidative activity of protein hydrolysates from Sangyod rice (Oryza sativa L.) bran, hydrolyzed with Alcalase (HA) and Flavourzyme (HF) with different degrees of hydrolysis (DH) (1, 3, 5%) was investigated. As the DH increased, DPPH, ABTS, hydroxyl and metal chelating activity of HF decreased (p<0.05), while ferric reducing antioxidant power (FRAP) and superoxide anion radical scavenging activity decreased (p<0.05). As the DH increased, DPPH radical scavenging activity of HA decreased, while ABTS radical scavenging activity increased (p<0.05). Superoxide anion radical scavenging activity, FRAP and metal chelating activity of HA were varied, depending on the DHs (p<0.05). Additionally, at the same DH tested, HA exhibited higher DPPH radical scavenging activity and FRAP than did HF (p<0.05). However, generally, HF showed higher ABTS radical scavenging activity than did HA (p<0.05). The results reveal that antioxidative activity of protein hydrolysates from Sangyod rice bran was designated by the DH and by the enzyme types employed. Keywords- Antioxidative Activity, Protein Hydrolysate, Sangyod, Rice Bran.
