Dextranase is also named α-glucanase, produced by submerged fermentation of Aspergillus oryzae followed by purification and formulation. The enzyme hydrolyzes the α-1, 6-glucosidic bonds in dextran molecule.
Mechanism and product standard
Dextranase is a hydrolase for specifically splittingα-1, 6-glucosidic linkages in dextran molecule, producing are mainly
isomaltose, isomalto-oligosaccharides and glucose.
During sugar processing leuconostoc, mesenteroides, streptococcus and other microorganisms are commonly found as contaminants, leading to generation of high molecular viscous dextran, which presents difficulties in processing, resulting in yield loss and sugar quality problems. Dextranase helps a lot to overcome these problems by getting rid of the dextran.
Total viable count/(CFU/mL)
The recommended dosage is 5-100g/t DS. The dosage has to be optimized based on each application, the raw material specifications, product expectation and processing parameters. It is better to begin the test with the convenient volume.
Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals.Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided.If irritation or allergic response for skin or eyes develops, please consult a doctor.
Storage and Shelf life
Storage： Keep sealed in a dry and cool place and avoid direct sunlight. Slight sedimentation is acceptable since it will not impact performance of the product.
Shelf life: 12 months in a dry and cool place.
