Use hydrogen peroxide to bleach shark fins, pistachios, etc.; use hydrogen peroxide to sterilize milk and dairy products; use hydrogen peroxide to ferment bread; use hydrogen peroxide to sterilize drinking water problems, etc. Industrial hydrogen peroxide is another hydrogen oxide besides water. The viscosity is slightly higher than that of water, and the chemical properties are unstable. Generally, it is stored in the form of a 30% or 60% aqueous solution, and its aqueous solution is commonly known as hydrogen peroxide. Hydrogen peroxide has strong oxidizing properties and is weakly acidic. Hydrogen peroxide manufacturers are mainly used for sterilization and external medical purposes, such as wound disinfection. The best ratio for testing blood: 6% hydrogen peroxide plus 0.005% methylene blue. Wuxi hydrogen peroxide with higher concentration (more than 10%) is used in textile, leather, paper, and wood manufacturing industries as bleaching and deodorizing agents. Hydrogen peroxide is also one of the components of hair dyes, and is also used as a material for synthesizing organic raw materials (catechol), medicine, metal surface treatment agent, polymerization initiator, etc. Can also be used as rocket propellant. Hydrogen peroxide has been widely studied and used in the development of food information processing. Scientists in living food from the Agricultural University of Science and Technology of China pointed out that excessive use or abuse of hydrogen peroxide is harmful to human health. Food-grade hydrogen peroxide is directly added to some foods as a food safety additive ingredient in my country, and some foreign countries have used it for decades. Experts call on the relevant education departments to formulate the sanitation service standards for the use of hydrogen peroxide in the production and operation of food companies as soon as possible.
