Food grade dextranase enzyme for food additive

 

PRODUCT DESCRIPTION

 

This product is Dextranase 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

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.

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.

 

SAFE HANDLING PRECAUTIONS

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.

 

WARNINGS

Keep sealed after use every time to avoid microbial infections and inactivation of enzymes until its finish.
