Study on the Deproteinization Method of Polysaccharide in Sugarcane Residue

Zhigang Huang

Abstract

Objective:To study the deproteinization by Sevag method and enzyme method of polysaccharide in Sugarcane Residue.Methods:Taking polysaccharide removal rate and polysaccharide content as criteria,deproteinization was treated by Sevag method and enzyme method.Results:After 8 times of deproteinization by Sevag method,polysaccharide removal rate was 77.47%,polysaccharide content was 63.6%.Polysaccharide removal rate was 71.84% by the optimum conditions of enzyme method.Conclusion:The deproteinization by Sevag method got to optimal effect after 8 times.The optimum conditions for enzyme method are as follows:enzyme concentration:2%;temperature:50℃;time:2h.
