1. The physical and chemical properties of hydrogen peroxide
Hydrogen peroxide, the scientific name of hydrogen peroxide, is a colorless and transparent liquid, 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 is 1.11g /cm3, melting point -0.89°C, boiling point 151.4°C, molecular formula H2O2, molecular weight 34.01. This product has a strong bactericidal effect, and the effect is more obvious under alkaline conditions. 2. Features of food grade hydrogen peroxide
Food grade hydrogen peroxide has high purity, few impurities, good stability, and does not contain toxic or harmful impurities.
Industrial grade hydrogen peroxide contains a lot of anthraquinone organic impurities, metal ions such as lead and arsenic, mechanical impurities, etc. Among these toxic and harmful impurities, such as anthraquinone and lead 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.
Food grade hydrogen peroxide has very good stability, especially suitable for the sterilization of dairy aseptic packaging. Aseptic filling machines such as Tetra Pak and Hangzhou Zhongya Machinery have high requirements on the stability of food-grade hydrogen peroxide.
