摘要
多孔淀粉是一种新型酶变性淀粉,本文采用α-淀粉酶和糖化酶复合酶解法制备多孔淀粉,对其工艺条件进行研究,当α-淀粉酶和糖化酶的比例为1:5、反应温度60℃,反应时间32h,pH4.5,酶用量2.0%时,可得到吸油率较高的多孔淀粉,可用于牡蛎水解液的进一步吸附。
The porous starch is a new modified starch prepared by enzymatic hydrolysis. The hydrolysis of the cornstarch by α-amylase and glucoamylase is determined in this paper. The optimal mass ratio of α-amylase to glucoamylase, pH value, temperature and hydrolyzing time are 1:5, 4.5, 60℃ and 32h, respectively. Under those optimal conditions, the porous starch with better absorbent ability for oil is obtained, which can be used for the absorption of oyster hydrolysate.
