Abstract: Maltodextrins were produced from corn starch using two kinds of α-amylase: a common one and a thermal-stable one. The common α- amylase and thermal-stable α-amylase conditions were given as follows, common α-amylase: temperature 84℃, hytrolysis time 20min, dosage of enzyme 16U/g; common thermal-stable α-amylase: temperature 95℃, hytrolysis time 40min, dosage of enzyme 15U/g.

Key words: corn starch; enzymatic hydrolysis; &alpha, -amylase;
