Overview

Xylanase by Aspergillus niger by submerged fermentation and preparation of high activity cellulase, xylanase within the wood products, Endo ratio is high, the molecular structure can damage the xylan in short time, improve the efficiency of conversion.

The product has a natural resistance to high temperature, high endochitinase activity, high stability and so.

Mainly used in food, brewing, pharmaceutical, food and other industries.

Quality index

Appearance: light yellow powder solid; liquid brown liquid

The enzyme activity of u/g (ML): 5000-10000

The optimum pH 3.0-5.0

The optimum temperature of 35-55 degrees Celsius

Activity definition (GB/T: 23874-2009) at 37 degrees Celsius, pH = 5.5, every minute from the degradation of xylan solution concentration of 5mg/ml in the release of 1 μ mol reduction enzyme amount of sugar needed for an enzyme activity unit (U).

The application process (adjusted according to test)

1 The food industry:

For improving flour processing, production of special flour, also can be used for quality improvement of baking and cooking products terminal. For best results, s estions and fungal alpha amylase, lipase and glucose oxidase with the use of.

The recommended dose of 1.0-3.0g/100 kg of flour (10-30ppm).

2 Beer brewing industry:

Decomposition of xylan or pentosan, reduce wort viscosity. To solve the resulting from xylan or pentosan carbohydrates such as turbidity.

Especially suitable for cleaning wheat in wheat beer or beer saccharification and filtration materials.

Recommended dosage: 100-300g/ tons of malt.

3 Feed industry:

Anti nutritional factor of xylan degradation in plant feed, promote digestion and absorption of nutrients, improve the utilization rate of feed. Promote the growth of intestinal bacteria and inhibit the propagation of harmful bacteria, improve the survival rate and the production performance of animal immunity.

Recommended use: take 10000U/g enzyme activity calculation, per ton of feed to s est to add 100-300g, concentrated feed, premix add the proportion.

Packaging, storage and shelf life

1 Packages: solid products of 20kg/ bags, 25kg/ barrels of liquid products.

2 Storage: should be stored in a dry, ventilated, no pollution, avoid high temperature storage.

3 Shelf life: solid products shelf life at room temperature for 12 months. The liquid product storage in cool environment, for a period of 3 months.
