Study on Canna Porous Starch of High Capacity of Adsorption for Oil with Double Enzymatic Method

Abstract

Canna porous starch was produced from corn starch,the optimum parameters for double enzymolysis based on single factor level are as follows:the weight ratio of α-amylase and glucoamylase is 1:3,enzyme concentration 1.5%,pH 5.0,temperature 55℃,time 18h,the porous starch with better absorbent for oil could be obtained.
