| 摘 要： | 通过对不同孔径膜的筛选试验,确定50βK的膜为富集茶多糖最好的膜,在此基础上进行了优化试验,优化试验处理后,截留干燥粉末中总糖含量达30.37%,多糖含量达16.89%,与对照相比抗羟自由基能力提高了39.89%,结果表明在纯天然产品的开发中,利用膜可以有效的富集茶多糖,并且能够保存了多糖活性。

| Abstract: | The 50 K membrane has been ascertained as the best membrane for separation and concentration of tea polysaccharides, and on the basis of the result, the treatment had been optimized, and the result showed that contents of total sugar reached 30.37%, and those of tea polysaccharides arrived at 16.89%. In compared with the control, the scavenging rate of ·OH were increased by 39.89%. The experiment showed that tea polysaccharides is separated and concentrated by membrane, and the activity of tea polysaccharides could be remained. |
