Hydrogen peroxide is the scientific name for hydrogen peroxide. It is a colorless and transparent liquid that is soluble in water, alcohol and ether. High concentrations of hydrogen peroxide are corrosive and will volatilize into oxygen and water when left open.
The product itself has a strong bactericidal effect, and the bactericidal effect is more obvious under alkaline conditions.
Food-grade hydrogen peroxide has improved purity, reduced internal impurities, improved stability, and removed toxic and harmful substances. Unlike industrial-grade hydrogen peroxide, there are no anthraquinone organic impurities in food-grade hydrogen peroxide, and metal substances such as lead and arsenic that are harmful to the human body. It can be used in food production and processing industries.
Food grade hydrogen peroxide can be decomposed into oxygen and water after sterilization, and it will not leave toxic substances. It does not need to be washed with water. It does not pollute the environment and conforms to the environmental protection concept of the country's production and development at this stage. Moreover, the use of food-grade hydrogen peroxide has a better sterilization effect and higher efficiency, and the products after sterilization can be stored for a long time.
Although the bactericidal effect of food-grade hydrogen peroxide is better, there is still some instability, which will be affected by some factors.
At lower temperatures and higher purity, the stability is better, but as the temperature increases, if heated to 153 ℃ or higher, violent explosive decomposition will occur, and at lower temperatures The decomposition process of hydrogen peroxide is relatively stable.
Among them, under acidic conditions, the properties of hydrogen peroxide are relatively stable and the oxidation reaction speed is relatively slow, while in alkaline media, hydrogen peroxide is unstable and the decomposition speed is relatively fast. In the process of disinfection and sterilization, an appropriate alkaline medium can be used to accelerate the oxidation rate of hydrogen peroxide and complete the sterilization work in a short time.
Some metal ions will accelerate the decomposition, such as ferrous ions, manganese ions, copper ions, etc. It is precisely because industrial-grade hydrogen peroxide contains a large amount of metal ions, so in the production process, stabilizers are added to inhibit the catalysis of impurities, so food-grade hydrogen peroxide cannot contact metals to prevent metal ions from entering the food Grade hydrogen peroxide.
