Xylanase can improve the elasticity of the gluten network in the dough, improve the processing performance of the dough and the stability of the dough, and significantly improve the structure and volume of the finished product. Optimum pH: 5.0, Optimum temperature: 50~60℃, recommended dosage: 2~16g/100kg flour
Xylanase Benefits
• Consistent and high speed of wort filtration
• Reduces risk of haze in beer origin from arabinoxylans and related carbohydrates
• Higher extract yield
• High utilization of beer filtration equipment and high brewhouse capacity
Xylanase Dosage
The recommended dosage is 0.1-0.3L of the enzyme preparation per ton of total raw materials, added at mashing-in. However, the optimal dosage depends on the composition of the raw materials and the specific process parameters and should be determined by testing different dosages at the brewery.
Xylanase Storage
Best before
When stored as recommended, the product is best used within 12 months from date of delivery.
Storage at customer’s warehouse
0-15℃
Storage Conditions
This product should be stored in a cool and dry place in sealed container, avoiding insolation, high temperature and damp. The product has been formulated for optimal stability. Extended storage or adverse conditions such as higher temperature or higher humidity may lead to a higher dosage requirement.

Xylanase Safety and Handling Precautions
Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
