摘要
Abstract
Rana chensinensis eggs were used as the materials to explore the effects of papain,alkaline protease,trypsin,neutral protease and protamex under their optimal action conditions on radical scavenging capacity of Rana chensinensis egg hydrolysates.The bioactive polypeptide with antioxidant activity was screened through the evaluation of scavenging capability against DPPH and hydroxyl free radicals.The results indicated that the polypeptide generated from 3 h digestion of Rana chensinensis eggs by alkaline protease combined with neutral protease revealed the highest scavenging capacity against hydroxyl and DPPH free radicals,which were 80.91% and 70.45%,respectively.关键词
