Abstract
This study focused on the dissolution rate of inonotus obliquus polysaccharide,and extrusion blasting methods was used in the pretreatment.The conditions of extrusion were optimizd with single factor and orthogonal test,and the effects of material moisture content,screw rotary speed of twin-screw extrusion and temperature on the dissolution rate of polysaccharide were explored,then the changes of cell structure were observed by scanning electron microscopic.The result shows that temperature was the greatest influence factor on the dissolution rate of Inonotus obliquus polysaccharide.The best extrusion conditions were as followed:the material moisture content was 9％,screw rotary speed was 100 r/min,temperature was 160 ℃,and the dissolution rate of inonotus obliquus polysaccharide is 43.98％.The dissolution rate of polysaccharide was 6 times higher than that without extrusion.In summary,the extrusion pretreatment was an effective method for improving the dissolution rate of inonotus polysaccharides.关键词
