Beer equipment is manufactured using specific techniques and principles. Today, I will explain how craft beer equipment is sterilized with hydrogen peroxide.
Hydrogen peroxide is a colorless, odorless, non-toxic, and transparent liquid that has undergone stable treatment and synergy. The collaborative effect of hydrogen peroxide and synergist significantly enhances its sanitization and infection-killing capabilities, resulting in better sterilization. Stable hydrogen peroxide possesses broad-spectrum, high-efficiency, and long-lasting sanitization properties.
Factors Influencing Hydrogen Peroxide Safety
Impurities
Impurities are crucial factors affecting the safety of hydrogen peroxide. Various metal ions, such as divalent iron ions, divalent manganese ions, divalent copper ions, trivalent chromium ions, etc., promote the decomposition of hydrogen peroxide. Adding a small amount of stabilizers, such as sodium stannate, sodium pyrophosphate, or 8-hydroxyquinoline, can inhibit the decomposition of hydrogen peroxide through reduction and complexation.
pH Value
Hydrogen peroxide exhibits relatively high stability at low temperatures and higher purity. At lower temperatures, the decomposition of hydrogen peroxide is relatively stable, and the decomposition reaction is as follows: 2H2O2 → 2H2O+O2 ↑ +46.94 kcal.
Temperature
To enhance the stability of hydrogen peroxide, it is necessary to control factors such as light, heat, metal ion content, and pH value. Pure and low-impurity hydrogen peroxide exhibits excellent stability due to its high purity and minimal presence of metal ions.
Light
pH conditions have a significant impact on the stability of hydrogen peroxide. Under acidic conditions, hydrogen peroxide exhibits high stability, and the rate of oxidation reaction is slow. In alkaline media, hydrogen peroxide is highly unstable, and the decomposition rate is very rapid.
