FOOD GRADE CATALASE
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
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;
