Preparation and properties of schizophyllan polysaccharide phosphorylated derivative
摘要
Abstract
Schizophyllan polysaccharide phosphorylated derivative was prepared from schizophyllan polysaccharide by modification with sodium tripolyphosphate and sodium trimetaphosphate.The effects of mass ratio of reactants, reaction temperature and reaction time on the degree of substitution were examined by single factor experiments. Experimental results show that the better conditions for the preparation are:mass ratio,m(sodium tripolyphos-phate + sodium trimetaphosphate,with equal molar blend):m(schizophyllan polysaccharide)= 2:1;reaction temperature,60 ℃;and reaction time,3 h.Under these conditions,the degree of substitution of phosphorylation achieves 0.052.The solubility,antioxidantion activity and moisturizing capacity of schizophyllan polysaccharide before and after phosphorylation were studied. Results show that the solubility and moisturizing capacity of schizophyllan polysaccharide are greatly improved by phosphorylation modification.The phosphorylation modifi-cation displays little effectiveness on improving antioxidation activity of the schizophyllan polysaccharide.关键词
