This invention provides a heterogeneous enzymatic synthesis method for branched-β-cyclodextrin, relating to the field of cyclodextrin derivative synthesis. The method includes: preparing a substrate syrup containing maltose, β-cyclodextrin, and a chelating agent; adding pullulanase to the substrate syrup to induce an enzymatic hydrolysis reaction; and inactivating the enzyme after the hydrolysis reaction to obtain a syrup containing branched-β-cyclodextrin. The addition of the chelating agent disrupts the hydrolyzed layer of pullulanase and β-cyclodextrin, forming a low water activity system. This causes the previously dissolved β-cyclodextrin in the syrup to become supersaturated and crystallize, precipitating out in large quantities as regular polygonal crystals. Simultaneously, pullulanase precipitates and accumulates on the surface of the β-cyclodextrin crystals, forming a heterogeneous enzyme-catalyzed reaction system. This method significantly improves upon the problems of low substrate conversion, long catalytic reaction time, high product impurity content, and high synthesis cost associated with homogeneous enzyme catalysis methods.
