Product Description
Xylanase
The xylanase produced by our company is a high-efficiency enzyme product prepared by liquid submerged fermentation, micro filtration, ultrafiltration and freeze-drying. This product
It is widely used in food, feed, beer, leather, paper and other industries.
Action mechanism:
Xylanase can degrade xylan into Xylooligosaccharides. Mainly including: β- 1, 4-d-endoxylanase and β- 1,4-d-exoxylanase, in addition to
There are some glycosidases, such as α- L-furan arabinosidase α- Glucuronidase, etc. After xylan is degraded into oligosaccharides, its viscosity decreases,
It can alleviate the symptoms of high viscosity of intestinal contents caused by eating wheat crops. So as to increase the diffusion rate of endogenous digestive enzymes and ultimately improve the nutrient
The digestibility of fraction. In addition, xylan is one of the components of the cell wall. After degradation, the solid structure of the cell wall is broken, and the nutrients inside are released,
So as to improve the digestibility of this part of nutrients.
Product characteristics: 1. Temperature range: 30-65 degrees, optimum temperature: 30-50 degrees;
2. PH range: 3.5-8.0, optimum pH range: 4.5-7.0; 3. Effect of metal ions on enzyme activity: Zn2 + activates xylanase activity, Mn2 + and Fe2 + inhibit it, and Cu2 + activates first and then increases with concentration
Inhibition.
Product specifications:
Common specifications: 10000-500000 U / g solid evaluation powder;
Main application fields:
1. Feed industry: xylanase can destroy the cell wall structure of plants, release nutrients in cells, and improve the digestibility of nutrients; Degradable and soluble
It can reduce the viscosity of chyme and improve the digestibility and absorption of feed nutrients; Improve the activity of endogenous digestive enzymes and promote the digestion and absorption of nutrients; Lower wood
The viscosity of glycans inhibits the growth of anaerobic microbial colonies.
Recommended addition amount: 100000 xylanase, 30-200g / t feed, the specific addition amount varies according to different use conditions and animal feeding
Section.
2. Food industry: xylanase can hydrolyze water-insoluble arabinoxylan in wheat flour, increase the fermentation performance of dough and baking performance of flour. On the face
Adding xylanase to the bag can improve the gas production and gas holding performance of the dough, increase the volume of the bread, and make the bread delicate, even pores and good taste;
Optimize the gluten network, slow down the evaporation of bread moisture, and reduce the hardness of bread crust.
Suggested addition amount: 100000 xylanase, 50-250g / T flour. The specific addition amount should be adjusted according to the type and use of flour.
Pb23-2 3. Health food industry:
Xylanase can decompose xylan into low xylan, promote the value-added of probiotics such as bifidobacteria in the intestine, reduce serum cholesterol, and regulate blood sugar,
Promote the absorption of calcium in the intestine and improve constipation.
Suggested addition amount: please call for details;
4. Papermaking industry: xylanase can hydrolyze xylan in pulp and improve lignin extraction rate; The pretreatment process of xylanase can bleach pulp,
Reduce the use of chemical bleach, improve the bleaching effect, and solve the environmental pollution in the papermaking process.
Recommended addition: 0.1-0.3% xylanase per 100000 units of dry pulp. The specific addition depends on the production process.
Inactivation:
The inactivation of the enzyme is generally determined by the substrate (substrate concentration, pH value, temperature, etc.), and pombol xylanase will be inactivated at 80 ℃ for 10 minutes.
Storage:
It is recommended to store in a cool and dry environment away from light. Storage temperature: below zero degrees.
If the storage time is too long or the storage conditions are unfavorable, the enzyme activity will be reduced in varying degrees; If the temperature and humidity are too high, it is necessary to appropriately increase the use amount during use.
