Food grade hemicellulase enzyme

 PRODUCT DESCRIPTION

This product is produced by submerged fermentation of a traditionally selected Bacillus lentus strain followed by purification, formulation and drying. The product contains variety of activities targeting at hemicellulose, an important part of plant cell wall. The product is used effectively in food, plant extract, feed, textile, pulp & paper, and even petrol oil drilling.  

MECHANISM

Hemicellulose comprises heterogenous polysaccharides made up of hexose, pentose and their derivatives, notably xylose and mannose. The multi-component hemicellulase is able to degrade different hemicellulose polymers to produce oligomers and their building blocks. Since hemicellulose makes big part of plant cell wall, and usually presents viscosity problem when released into solution, their degradation leads to disruption of plant cells, liberation of cell inclusions and reduction in viscosity during wet processing of plant materials.  

APPLICATIONS

l  Fruit and vegetable processing: Used together with pectinase and cellulase for juice yield improvement and juice clarification;

l  Coffee: Increases extraction yield of coffee；

l  Edible oil extraction: Increases oil yield by enzymatic pretreatment.；

l  Feed: Improves biological value and utilization of feed by removal anti-nutritional components in feed.

l  Petrol oil drilling: Used as an enzymatic breaker to degrade biological mannan containing thickening agent like guar gum, xanthan gum, konjac gum, etc., reducing the environmental pollution by fracturing liquid.；

l  Pulp & Paper: Bleaches pulp by degrading hemicellulose and reduce the use of chemicals.

APPLICATION RECOMMENDATION

The recommended dosage is 0.01-1.0%/t DS. The dosage has to be optimized based on each application, the raw material specifications, product expectation and processing parameters. It is better to begin the test with the convenient volume. 

SAFE HANDLING PRECAUTIONS

Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor. 

WARNINGS

Keep sealed after use every time to avoid microbial infections and inactivation of enzymes until its finish.
