摘 要：
Gelatin extracted from deer bone was hydrolyzed for 3.5-120 min. The degree of hydrolysis was higher from Alcalase- hydrolyzed gelatin than that from neutral proteinase-hydrolyzed gelatin. Alcalase-hydrolyzed gelatin exhibited a stronger antioxidant activity than that of neutral proteinase-hydrolyzed gelatin. Hydrolysates showed strong radical-scavenging ability and Fe~(2+)-chelating activity, both of which were influenced by hydrolysis time. Although nonhydrolyzed gelatin displayed a certain antioxidative effect, it was far less than that of hydrolysates. The hydrolysates of deer bone gelatin can work as a radical stabilizer and metal ion chelator to inhibit lipid oxidation.
