The current situation of food-grade hydrogen peroxide at home and abroad is abroad, and food-grade hydrogen peroxide has long been widely used in the food industry. Food-grade hydrogen peroxide is widely used in the aseptic packaging of dairy products and beverages, as well as the production and processing of beer, drinking water, aquatic products, fruits, vegetables and other foods.
There has never been food-grade hydrogen peroxide in our country, and the domestic food industry has more and more requirements for hydrogen peroxide in food, especially in the dairy industry. Aseptically packaged pure milk and yogurt must be sterilized with food-grade hydrogen peroxide. . Since the production of food-grade hydrogen peroxide has certain technical difficulties, there has been no food-grade hydrogen peroxide manufacturer in China. There are only two ways to use food-grade hydrogen peroxide in the food industry: one is to import food-grade hydrogen peroxide from abroad, and the other is to use industrial-grade hydrogen peroxide instead. .
The physical and chemical properties of hydrogen peroxide and the characteristics of food grade hydrogen peroxide:
1. The physical and chemical properties of hydrogen peroxide. The scientific name of hydrogen peroxide is hydrogen peroxide. It is a colorless and transparent liquid. It is soluble in water, alcohol and ether. It is corrosive at high concentrations. When left open, it will gradually decompose into oxygen and water. The density of 30% hydrogen peroxide It is 1.1g/cm3, the melting point is -0.89°C, the boiling point is 151.4°C, the molecular formula is H2O2, and the molecular weight is 34.1. This product has a strong bactericidal effect,
Under alkaline conditions, the effect is more obvious.
2. Features of food grade hydrogen peroxide Food grade hydrogen peroxide has high purity, less impurities, good stability, and no toxic and harmful impurities.
Industrial-grade hydrogen peroxide contains a large amount of anthraquinone organic impurities, metal ions such as lead and arsenic, and mechanical impurities. Among these toxic and harmful impurities, anthraquinone, lead and arsenic are carcinogens, so they cannot be used in the food industry.
High-purity hydrogen peroxide is purified by a special method to remove impurities in the raw materials. It is a high-quality, high-purity hydrogen peroxide, which can be widely used in various fields in the food industry.
