Abstract
Provided are a method for preparing an immobilized multi-enzyme system, and a method for producing tagatose by the immobilized multi-enzyme system. The immobilized multi-enzyme system is formed by uniformly mixing a porous dopamine microsphere with a multi-enzyme mixture which is used for producing tagatose. Five enzymes in an enzymatic catalysis path for converting starch to tagatose are co-immobilized by means of a porous microsphere to obtain an immobilized multi-enzyme system, the immobilized multi-enzyme system is used to catalyze conversion of starch into tagatose, and thus, enzymes can be recycled, thereby greatly reducing the amount of enzymes required for preparation of tagatose, and reducing the production cost.
