Hydrogen peroxide, a colorless and transparent liquid, dissolved in water, alcohol, and ether, high concentrations of hydrogen peroxide have corrosive, expacted, which is volatilized to oxygen and water.
The bactericidal effect of the product itself is strong. Under alkaline conditions, the bactericidal effect is more obvious.
Food grade hydrogen peroxide, purity increase, internal impurity reduction, and stability have also been improved, and toxic and harmful substances are removed. Unlike industrial grade hydrogen peroxide, there is no metal substance in the food-grade hydrogen peroxide, as well as metal materials harmful to the human body, and can be used in the food production and processing industry.
Food grade hydrogen peroxide after completing sterilization, can be broken down into oxygen and water, and will not leave a toxic substance, no need to rinse with water, no pollution to the environment, in line with the environmental protection concept of national production and development at this stage. Moreover, the use of food grade hydrogen oxygen itself is better, high efficiency, and after sterilizing products can be used for long-term preservation.
Although the bactericidal effect of food grade hydrogen peroxide is better, there is still a certain instability, which will be affected by factors.
At lower temperatures and higher purity, the stability is better, but with the temperature rise, if heated to 153 ° C, or higher temperature, violent explosive decomposition occurs, and at a lower temperature Next, the decomposition process of the hydrogen peroxide is relatively stable.
Under acidic conditions, the properties of hydrogen peroxide are relatively stable, and the rate of oxidation is slow, and in the alkaline medium, the hydrogen peroxide is unstable, and the decomposition rate is faster. In the process of disinfection, the appropriate alkaline medium is used, and the oxidation speed of the hydrogen peroxide is used to complete the sterilization operation in a short time.
Some metal ions can accelerate decomposition, such as divalent iron ions, divalent manganese ions, divalent copper ions. It is also because of a large number of metal ionic substances in industrial grade hydrogen oxygen, so in the production process, the stabilizer will be added to suppress the catalytic effect of impurities, so the food grade hydrogen is not able to contact the metal to prevent metal ions from entering the food. Level hydrogen peroxide.
