Thermostable xylanase powder for food feed pulp & paper, textile

 PRODUCT DESCRIPTION

Xylanase (Thermostable) is produced by submerged fermentation of Trichoderma reesei followed by purification, drying and formulation. This product has efficient hydrolytic activity at a higher temperature (70℃-90℃).

 

MECHANISM

The Xylanase is an enzyme complex degrading xylan into Xylo-oligosaccharide and xylose. The product contains β-1,4-xylanase and β-xylosidase most but also some β-1,4-xylanase, β-xylosidase, α-D-glucuronidase, α-L-furan arabinosidase, acetyl xylanase and feruloyl esterase, which ensures complete degradation of natural xylan in plant materials.

 

APPLICATIONS

l  Feed: This product helps with the release of nutrients from feedstuff by efficiently hydrolyzing xylans and promotes absorption by reducing viscosity of feed in animal’s digestive tracts, and thus improves the biological value of the feed.

l  Baking: Either added into flour to produce specialty flour for bread or steamed bun, mixed with other ingredients to make improver, or added during baking to improve dough handling properties, product volume, and crumb structure.

l  Brewing: Added in mashing to reduce wort viscosity and ease filtration.

l  Starch: Helps the separation of starch from grains to have higher yield and smooth operation.

The recommended dosage is 0.01-0.5kg/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.
