摘要: 利用金丝小枣(ZiZyphusJujubacv.Jinsixiaozao.)制取枣多糖,并对该制备过程中的两个主要工序—提取、脱色工艺条件进行研究。结果表明,枣多糖最佳的提取工艺条件为:超声功率86~96W,提取温度45~53℃,提取时间20min,料液比1:20;聚酰胺是理想的脱色剂,具有脱色、去除蛋白质、杂质三种功能,其脱色的最佳工艺条件为:聚酰胺用量为需脱色粗多糖的4倍,聚酰胺柱用1倍柱体积的去离子水以1.5ml/min的流速进行洗脱。

Abstract:  Polysaccharides were extracted from ZiZyphus Jujuba cv. Jinsixiaozao. Processes on supersonic extraction and decolorization were studied. Results showed that optimum extraction conditions are: sonic power ranges from 86W to 96W with extraction temperature from 45℃ to 53℃, and time 20min and stock ratio of 1:20. The best decolorant is polyamide. The content of polyamide is 4 times of crude polysaccharides, and the polyamide column is eluted with 1 column volumes of deionized water at flow rate of 0.8ml/min.
