富硒平菇水溶性蛋白提取及抗氧化活性
Extraction of water soluble protein from selenium contained Pleurotus ostreatus and antioxidant activity in vitro
摘要
Abstract
In this experiment,the main research material was dried selenium-enriched Pleurotus ostreatus,in order to get optimization of extraction technology for water soluble protein and determine its antioxidant activity in vitro,single factors and orthogonal experiments were designed.The results showed that the best conditions for extraction were described as follows:extraction temperature 30 ℃,extraction time 4 h and the ration of raw material to water 1∶ 30,under this conditions,the content of water soluble protein reached (8.5 ± 0.29)mg/mLThe water soluble protein had the capacity of scavenging superoxide anion free radical,hydroxyl radical and ABTS radical,and the scavenging rate could get higher than 50％ at the concentration of 1.0 mg/mL关键词
