Abstract

The preparations and the characteristics of the chitosan-sodium alginate microcapsules containing immobilized α-amlyases are described in this paper. The results indicated that ：（1） the ideal spherical morphologies and the narrow range distributions of two different kinds of microspheres of immobilized α-amlyases are obtained; (2) compared with the free enzymes, there are more higher thermal and PH stabilities, excellent in the repeated use of properties and no deterioration in longer storage in the two different kinds of immobilized α-amlyases; (3) the michaelis constant (Km) and the maximum rate of two different kinds of immobilizedα-amlyases are larger than those of frees.

Key words： microcapsules microcapsul immobilization
