Study on Extraction of Ginger Polysaccharide by Enzyme Complex

The optimal extraction conditions of ginger polysaccharide were studied using cellulase,papain and pactic enzyme simultaneously. The results indicated that by 1.0% cellulase,0.5% pectic enzyme plus 2.0% papin,under the conditions of extraction temperature 50 ℃,extraction time 60 min and pH 4.5,the extraction rate of ginger polysaccharide is the highest,272.69mg/g,and its purity is 69.8%.
