Extraction and Content Determination of Polysaccharides from Zizyphus Jujube Mill

Taking red jujube as raw materials,in the traditional water extraction,alcohol sinking method extracting jujube polysaccharide on the process of water extraction process of adding papain, papain and its hydrolysis conditions of polysaccharide extraction yield,the influence of the optimal extracting technological conditions is determined. This paper uses the red jujube polysaccharide extraction yield as index,liquid ratio,enzyme amount,extraction temperature,extraction time as factors,designs orthogonal experiment. Experimental results show that red jujube polysaccharide in the best condition for material liquid is 1∶7,plus enzyme is 4.0 mg/mL,extraction temperature is 60 ℃,the extraction time is 3 h,jujube polysaccharide can be extracted as the basis of optimization of process.
