Xylanase Enzyme Used In Beer Brewing For Reducing Wort Viscosity XY22L
Introduction
Xylanase is made from Trichoderma reesei through cultivation and extraction technique. This product contains abundant xylanase, which can catalyze the xylan in plants efficiently into low molecular material, such as xylose etc., so as to release the protein and sugar in plants adequately.
Characteristics
| Declared Activity | 22000 u/g |
| Production Organism | Trichoderma reesei |
| Physical Form | Liquid |
| Color | Snuff color. Color can vary from batch to batch. Color intensity is not an indication of enzyme activity. |

- Higher extract yield.
- High utilization of beer filtration equipment and high brewhouse capacity.
Dosage
The recommended dosage is 0.1-0.3 L 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.
Package: 1 kg / bag.
Storage: Keep sealed in a dry and cool place and avoid direct sunlight.
Shelf Life: 12 months in a dry and cool place.
Safety
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 the human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
