Abstract
Took polysaccharide material of rice husks as the main subject.Through the determination of monofactory experiments and scanning electron microscope（SEM） to research the effect of polysaccharide content and structure by different pretreatments,alkali treatment and extrusion.Moreover,proposed a new method of alkali combined with extrusion pretreat rice husks,and used polysaccharide content as indicator,adopted the analysis method of response surface methodology to determine the optimization conditions of the pretreatment alkali combined with extrusion on rice husks：extrusion,screw speed 110r/min,moisture content 40%,barrel temperature 105℃;alkali,solid-liquid ratio 1：20;the concentration of Sodium hydroxide 0.72mol/L;temperature 70℃;treatment time 35min.On conditions of the optimization,the polysaccharide content of the rice husks could achieve 44.74%.关键词
