酵母发酵法纯化枸杞多糖

【摘要】 采用水浸提法提取枸杞中的粗多糖,应用正交实验设计法对水浸提工艺进行了优化,从而确定了其最佳工艺条件,即在65℃下,料水比1∶9,浸泡48h;本文同时探讨了在枸杞浸泡液中添加酵母菌,利用酵母在生长过程中消耗单糖及双糖等寡糖来提高枸杞多糖的纯度,以达到纯化枸杞多糖的目的。更多还原

【Abstract】 In the paper,water extraction process was selected to extract polysaccharide from lyciun barbarum.And the optimized condition is obtain by orthogonal experiments and effecting factors analysis was show as follow:the temperature was 65℃;ration of solid to liquid was 1:9;time is 48h.Meanwhile yeast was added to the mixture to promote purity of lycium barbarum polysaccharide.更多还原
