Extraction method of hericium erinaceus polysaccharide

From the paper

Abstract

The invention provides a hericium erinaceus polysaccharide extraction method with high product yield and good purity. The method comprises that: hericium erinaceus dried powder is added with water, is extracted by 8 to 20 KHz ultrasonic under the temperature of 50 to 80 DEG C for 0.5 to 2.0 hours, and is filtered the filtrate is hydrated orderly by sufficient cellulose, pectinase and papain, finally is added with hydrogen peroxide to be stirred in heat preservation under the temperature of 30 to 50 DEG C for 0.5 to 1 hour, and is hyperfiltrated by a hyperltration membrane the components with the molecular weight of more than 10000 dalton are collected, frozen and dried to obtain the hericium erinaceus polysaccharide. The hericium erinaceus polysaccharide extraction method has the advantages that 1. the prepared product has high purity wherein, the content of Beta-dextran is as high as more than 40 percent and the biological activity is high, and the hericium erinaceus polysaccharide yield can reach 12.2 percent 2. the hydrogen peroxide is adopted to decolorize, the conditions are mild, the polysaccharide structure is difficult to damage and the by-product is water, the method is green and environment-friendly, and coincides with the production requirements of the health care food.
