Antioxidant Activity and the Possible Mechanism Pig Skin Collagen Hydrolysates
摘要
Abstract
In order to analysis antioxidant activities of pigskin collagen hydrolysate comprehensively, the reduc- tion capacity, scavenging free radical capacity, lipid oxidative capacity, metal chelating ability of pig skin collagen hydrolysate with different hydrolysis time and concentration were studied. Pig skin collagen hydrolysates possessed re- markable reducing power and strong radical-scavenging ability, and both were increased with hydrolysis time. The protein hydrolysates also showed strong Cu2+ and Fe2+ chelation ability, and the antioxidant activity increased with substrate concentration. The reducing power of 4% pigskin collagen with 6h hydrolyzing was similar to those of 0.02% ascorbic acid. The results demonstrated that enzyme-hydrolyzed pig skin collagen can act as a hydrogen do- nor, a radical stabilizer, as well as a metal ion chelator to inhibit lipid oxidation.关键词
