DEXTRANASE

Description:

Dextranase is an endo-dextranase enzyme belonging to the family of glucosyl transferases obtained from selected strain of microorganism. It preferentially cleaves the 1, 6-A- glucosidic linkages in dextran and its degradation products.

It enhances sugar mill processing by hydrolyzing dextran in sugarcane juice and syrup, thereby reducing viscosity and aiding refining.

This results in decreasing the viscosity of cane facilitating sugar processing.

DOSAGE GUIDELINES

Dextranase enzyme is a formulated product, which can be used as follows.

Parameters                    Guidelines
Batch                                 2-3 ppm of cane juice to be dosed in the third evaporator
Temperature                 900 C to 950 C
PH                                                      5.8 – 7.0

ENZYME STABILITY

Dextranase is stable over a wide PH and temperature range making it most suitable for use in sugar processing. It is active over a PH range of 3.0 – 7.5 and temperature of  350 C to 700 C

Solubility                                        Miscible in Water

ADVANTAGES

  • Promotes hydrolysis of dextran thereby reducing viscosity resulting in improved refined product.
  • Acts upon a sugarcane juice with wide range of sucrose content and PH optimum for use in mixed juice.
  • High specificity for inner bonds of dextran polymer as compared to end sugar unit, thereby making it more effective in cleaving dextran.
  • Free from invertase activity hence quality of sugarcane juice and final product is not affected.

 PACKING

Dextranase is available in standard 25 kg drums but can be custom packed on request.

STORAGE AND SHELF LIFE

Dextranase should be stored in cool and dry environment. When stored in closed containers at temperatures less than  350 C it maintains its activity for a period of 9 -12 months.

SAFETY & ENZYME HANDLING

Dextranase is non carcinogenic and is perfectly safe to handle. However prolonged contact is not advised as this may irritate skin, eyes and other mucous membranes. Inhalation of enzyme must should be avoided. In case of contact with eyes or other sensitive organs, rinse with clean water for at least 15 minutes.
