Optimization of polysaccharide extraction from Lethariella Cladonioides by compound enzymes method
摘要
Abstract
To obtain the optimized process parameter of extracting the polysaccharide from Lethariella Cladonioides,single factor experiment and orthogonal test were adopted.The effect of different solid-liquid ratio,pH,temperature of enzymatic hydrolysi（cellulase,Pectinase,papain）,extracting time and compound enzymes mixture ratio on the extraction rate of polysaccharide from Lethariella Cladonioides were studied.The results showed that compound enzyme best ratio was 2.0% cellulase,2.0% pectinase,0.5% papain.The impact factors were as following：solid-liquid ratio〉temperature〉pH〉time.The optimized process parameter was solid-liquid ratio 1：40,pH4.5,temperature 40℃,time 80min.Under this condition the extraction rate of polysaccharide reached to 8.91%.This method was suitable for polysaccharide extraction from Lethariella Cladonioides.关键词
