β- Mannanase

β- Mannanase
β- Mannanase
Product Code : 54
Product Description

Product name:- Mannanase;

Specifications:

Enzyme Activity: 500,000U/g;

Effective temperature: 30 " 65, optimal temperature: 50" 55

Effective pH: 5.5~7.0;

Definition of Enzyme Activity: One unit of β-mannanase activity was defined as the amount of enzyme that produced 1 μg of reducing sugar 1min at pH 6.0, 40 ℃, expressed as U/g.

Applications:

In health food aspects, mannanase can hydrolyze gum, which contains mannan, to  degrade short oligosaccharides into different glucose units.Branch mannan oligomer contained 2–10 mannose can reduce the levels of cholesterol as well as blood glucose of human, alleviate constipation, and has the ability to increase intestine probiotics and reduce pathogenic bacteria.

 

 In brewers yeast further processing products (yeast extract paste, nucleic acid, yeast cell wall immunopotentiating agents),some hemicellulases(e.g. β-mannanase and glucanase) have a combined effect on yeast cell wall degradation.

 

 In paper making industry, treating paper pulp with enzyme instead of traditional  alkaline, the usage of hemicellulases such as β-mannanase and β-xylanase together can effectively eliminate hemicellulose of paper pulp, therefore distinctly improve paperiness.

 

In textile industry, the process of degrading hemicellulose gelatine of crude cellulose, such as the usage of β-mannanase in the process of ramee unglued, can degree the tightness of cellulose as well as residual glue of ramee cellulose, and enhance the quality of refined dry flax. It can also eliminate superfluous dye of textile printing and dyeing products, in- stead of traditional chemical treatment, so as to reduce energy expenditure and environmental pollution.

 

In petroleum industry, β- mannanase is also a gel breaker of fine quality, with advantage of high efficiency, low cost and light damage to the stratum.

 

In feed industry, the product can be used as feed additive solely to eliminate the anti-nutritional effect of β-mannan in soybean meal and improve nutritive value. In corn- soybean meal diets, when adding 30–100 g/T β-mannanase with the activity of 500,000 U, can increase metabolizable energy of 100–150 kcal/kg, as well as the digestibility of protein and crude fiber 2.57% and 6.45% respectively.

Stability and Storage

This product is bioactive substance. The shelf life is 6 months from date of production when kept in a cool, dry place and kept out of sunlight and water. Under this condition, the enzyme activity can keep more than 90 % of the initial. The product is prone to absorb moisture and lump, but it doesn’t affect the quality. It should be bound up after use, avoiding the absorption of moisture.
