Peroxide removing Catalase enzyme

PRODUCT DESCRIPTION

This product is produced by fermentation of a selected microorganism followed by purification and formulation. The enzyme effectively catalyzes the hydrolysis of hydrogen peroxide into oxygen and water, which can be widely used in food, textile, paper, electronics, and other industries to remove hydrogen peroxide with a significant saving of water resources and energy.

MECHANISM

Catalase catalyzes the decomposition of hydrogen peroxide to water and oxygen.

（1）H₂O₂ + Fe(III)-E → H₂O + O=Fe(IV)-E(.+)

（2）H₂O₂ + O=Fe(IV)-E(.+) → H₂O + Fe(III)-E + O₂

APPLICATION

Ø  Textile Industry

l  An ecofriendly solution to remove hydrogen peroxide after bleaching and before dyeing without damaging fibers, saving water, energy and time;

Ø  Paper making Industry

l  Degradation of residual hydrogen peroxide after the bleaching;

Ø  Electronics Industry

l  Removal of hydrogen peroxide after circuit erosion, saving water, energy and time;

Ø   Food Industry

l  Elimination of residual hydrogen peroxide wherever relevant, like in food bleaching, starch denaturation, milk production, egg product processing, cheese manufacture and other cases, where hydrogen peroxide is used either as bleaching agent, oxidant, or disinfectant; also used as leavening agent of baking food;

Ø  Potential use for other application where decomposition of hydrogen peroxide is beneficial.

The recommended dosage is 0.01-1kg/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.
