Comparison of the kinetic behavior of dextranase and pullulanase applied to pan boiling: Laboratory and factory trials [Full subscriber]

Abstract Dextran occurrence is widely spread out in the Thai sugar industry. Process streams contaminated with dextran are difficult to treat due to the high juice flow per minute and the high cost of enzyme. Pullulanase, an enzyme capable of hydrolyzing the a-1,6 glucosidic linkage, was studied by comparing its kinetic behavior with that of dextranase. Both enzymes were applied to high viscosity (highly contaminated) low water content massecuites A and C and also trialed in the crystallization of vacuum pan A and C in the factory. The results showed that in massecuite A and pan A, (~80 °Brix, 70…
