富硒花生中含硒蛋白的提取及其抗氧化性的研究
The extraction of different solubility protein in selenium enriched peanuts and the analysis of their antioxidant activity
摘要
Abstract
The dry defatted selenium enriched peanuts （SP） powder （0.3147ug/g） had a 2.5- fold higher mean total selenium concentration than general peanuts （GP） power （0.1233ug/g）.The extraction of protein was 23.39% of peanuts, alkali soluble protein was the main component of protein in SP, it accounted 92.82% for total soluble protein,and it combined 77.33% of selenium in total protein.In different solubility protein extracts from SP,watersoluble protein extracts had higher DPPH free- radical scavenging activity, higher reducing activity and longer induction time than other protein extracts, it could be largely explained by its selenium concentration.关键词
