摘要
Abstract
Porous arrowroot starch was prepared by simultaneous hydrolysis with α-amylase and glucoamylase.The effects of enzyme dosage,glucoamylase-to-α-amylase ratio,pH,hydrolysis time and hydrolysis temperature on the oil-absorbing capacity of porous arrowroot starch were investigated.The optimal hydrolysis conditions for preparing porous arrowroot starch were determined by orthogonal array design method to be 3：1 glucoamylase-to-α-amylase ratio,0.6% total enzyme amount,pH 5.0,12 h hydrolysis time and 50 ℃ hydrolysis temperature.Under these conditions,the maximum oil-absorbing rate of 3：1 and excellent pore formation were achieved.关键词
