Xylanase is a high-efficiency enzyme preparation produced via submerged liquid fermentation, microfiltration, ultrafiltration, freeze-drying and other processes. It is widely applied in food, feed, beer brewing, leather, papermaking and other industries.
Temperature range: 30–65 °C, optimal temperature: 30–50 °C
pH range: 3.5–8.0, optimal pH range: 4.5–7.0
Effects of metal ions on enzyme activity: Zn²⁺ activates xylanase activity; Mn²⁺ and Fe²⁺ exert inhibitory effects; Cu²⁺ first activates and then inhibits the enzyme activity as its concentration rises.
When added to feed, xylanase can boost the digestibility and absorption rate of nutrients in feed, enhance the activity of endogenous digestive enzymes to facilitate nutrient digestion and uptake, and inhibit the proliferation of anaerobic microbial flora.
Recommended dosage: For xylanase with an activity of 100,000 U/g, add 30–200 grams per ton of feed. The exact dosage shall be adjusted according to varying application conditions and livestock species.
Xylanase hydrolyzes water-insoluble arabinoxylan in wheat flour, improving dough fermentation performance and the baking properties of flour.
Recommended dosage: For xylanase with an activity of 100,000 U/g, add 50–250 grams per ton of flour. The specific dosage shall be adjusted based on flour varieties and practical application scenarios.
