The preparation of the micro-porous cassastarch was studied and oil absorption were investigated. Some factors, such as reaction temperature, reaction time, enzyme addition, enzyme combination and reaction pH were studied as the main factors for oil adsorption capacity. The single element anti orthogonal teat showed the optimum enzyme reaction condition are as follows: The optimal mass ratio of α-amylase to glucoamylase1:5, starch concentration 20%, reaction temperature 50℃, reaction time 8 h, enzyme addition 1.0% and pH 5.0. Under these conditions, the capacity of oil adsorption is up to 92%.
