Application Method
Sugar industry: In the sugar industry, leuconostoc mesenteroides streptococcus and other microorganisms are through secretion glucansucrases catalyze sucrose to glucose, glucose further polymerized to form dextran. The dextran is a high molecular weight polysaccharide polymer, and the type of glycosidic linkage is mainly α-1, 6 glycosidic bond. The existence of dextran will have serious impact on sugar production, obviously increasing the viscosity of sugar, reducing the sugar filtration, so that crystallization of sucrose generate abnormal morphology crystals, increase the sugar costs while affect product quality. The use of dextranase can effectively improve the speed of heating cane juice, shorten time to clarify and crystallize, to eliminate the adverse impact of crystallization, thereby improve the production efficiency and yield of sugar. Use of enzyme activity 10000u/g of the product, contains 1000ppm dextran concentration in the cane juice, add 8ppm liquid enzyme, the effect of hydrolysis as below:      #p#分页标题#e#
Other use: The addition of dextranase in toothpaste and mouthwash has good effect on prevention and treatment of dental caries and gingivitis.
