Abstract: There was a high isomaltooligosaccharide concentration in reaction solution after a period of catalytic reaction by impurified enzyme of α-transglucosidase. The optimum pH value and temperature of the impurified enzyme were 5.0 and 55℃ respectively. The effect of different metal ions on enzyme activity was different. The results of orthogonal experiment showed that the optimum catalytic reaction conditions were pH 5.15, 55℃ and 3h(reaction time).

Key words: α-transglucosidase, coarse enzyme, property
