Abstract:
This paper studies the effect of 5 solutions degrading corncob cellulose by gradient selecting and BoxBehnken response surface optimizing.The study shows that 2% NaOH can effectively degrade corncob cellulose and obtain solubility pectin and it’s the best reagent to degrade comcob.The optimum values of extraction are determined to be A3B2C1:2% NaOH concentration,27∶1 V∶W,650 W×40 s microwave,and the BoxBehnken model is applicative(R2=0.980 7,p<0.000 1**);The yield can reach to more than 12% and the content can reach to more than 36%.
