Activity Definition
one unite(U/mLorU/g) means the amount of catalase need to decompose 1 micro molar of hydrogen peroxide in one minute at 37℃ and PH7.
Function
1. To remove the generated or residual hydrogen peroxide from food, food additives and ingredients after disinfection, bleaching or processing.
2. To remove the odor caused by hydrogen peroxide from food, like milk, eggs, etc., after ultraviolet irradiation.
3. To remove the residual hydrogen peroxide after disinfection of dairy equipments.
Product characteristic
1. Exclusive microbial fermentation, good stability, high efficiency;
2. A broad temperature range of activity, excellent thermostability and high enzyme activity at 20℃-60℃;
3. A wide pH range of activity. High enzyme activity under pH 5 to 11, adapt to different industries;
4. High purity without impurities, good storage stability, convenient for transportation and storage
Product Functions
1. Textile Industry: to remove hydrogen peroxide after bleaching and before dyeing, saving water, energy and time, not damaging the fibers and dyes, and do not pollute the environment;
2. Papermaking Industry: monitoring and optimizing the amount of hydrogen peroxide in bleaching process, degrading residual hydrogen peroxide after the bleaching;
3. Electronics Industry: to remove hydrogen peroxide after eroding germanium, silicon transistors and semiconductor components; saving water, energy and time;
4. Hydrogen peroxide decomposition also applicable to other industries.
Application in textile industry:
Catalase is applied and used in the dip process of equipments like jet dyeing machine, piston scraping, overflow, bobbin dyeing, dyejigger, etc.
Operation method:
1. Discharge bleaching solution.
2. Re-pull in water, and adjust the temperature and bath ration to that suitable for the later dyeing.
3. Check and make sure the pH at 5-10, temperature at 40-55℃.
4. Add 0.1-0.4 g/l Catalase to remove the hydrogen peroxide.
5. Examine the hydrogen peroxide contains in the solution, If hydrogen peroxide still can be checked, recheck the solution after 5-10 minutes.
6. When the hydrogen peroxide is completely
removed, dyeing can be started in the solution.
