Dextranase (Alpha-glucanase)
Product Description
Dextranase, called alpha glucanase, It is a high-yielding strain from Chaetomium gracile screened by mutagenesis, which is through liquid deep fermentation extract from refining. It is widely used in the field of sugar, toothpaste and etc.
Action Principal
Dextranase is a hydrolase for specificity splitting decomposition α-1,6-glucoside linkages of dextran molecule,which outcome production are mainly isomaltose, isomalto-oligosaccharides and glucose.
Product Characteristic
Temperature range:35ºC~65ºC optimum temperature 55ºC~60ºC
Ph range: effective Ph 3.0 ~8.0 optimum Ph5.0 ~6.0
Product Feature
Product specification: liquid: 30000U/mL; Powder: 100000U/g
Activity definition: one dextranase unit is defined as the quantity of enzyme that will liberate reducing sugar at a rate of 1µmol per minute under the condition of hydrolyze dextran(2% dextran T2000) at 55ºC and PH5.5 within 10min
GB1886.174-2016<<National Food Safety Standard-Food Additives-Enzyme Preparations For Food Industry>>
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. Dextran is a high molecular weight polysaccharide polymer, and the type of glycosidic linkage is mainly α-1, 6 glycosidic bond. Dextran existence will have serious impact on sugar production, obviously increasing the viscosity of sugar, reducing sugar filtration, so that crystallization of sucrose generate abnormal morphology crystals, increased sugar costs while affect product quality. Dextranase use, can effectively improve the speed of heating cane juice, shorten time to clarify and crystallize, to eliminate the adverse impact of crystallization, thereby improving the production efficiency and yield of sugar. Use of enzyme activity 10000u/ml of the product, containing 1000ppm dextran concentration in the cane juice, add 8ppm liquid enzyme, the effect of hydrolysis as below:
Other use: addition of dextranase in toothpaste and mouthwash on prevention and treatment of dental caries and gingivitis has good effect.
