The main uses of food-grade hydrogen peroxide are covered by the following numbers.
First, it is used for disinfection and sterilization in the food processing process. In the food production environment, such as workshops, equipment, pipelines, etc., disinfection with food-grade hydrogen peroxide can eliminate many harmful microorganisms, such as bacteria, viruses, fungi, etc., to ensure that the production environment is clean and sterile, so that the food is free from microbial contamination, to ensure its quality and safety. And after decomposition, it is only raw water and oxygen, without harmful residues, and will not cause adverse effects on food and the environment.
Second, it is used for food preservation. Some foods, such as fresh-cut fruits and vegetables, aquatic products, etc., are easily deteriorated due to microbial growth and oxidation. Appropriate treatment with food-grade hydrogen peroxide can delay the deterioration process of food and prolong its shelf life. This is because hydrogen peroxide can inhibit the growth of microorganisms, and has certain antioxidant properties, slowing down the oxidation reaction of food ingredients.
Third, used for food bleaching. In some food processing, such as flour, edible oil, etc., food-grade hydrogen peroxide can be used as a bleach. It can remove the color of food, improve its appearance quality, and make its color more pleasing to the eye. However, when using, follow relevant standards and norms, and strictly limit the dosage to prevent excessive use from being harmful to human health.
Fourth, used for drinking water treatment. In the process of disinfection and purification of drinking water, food-grade hydrogen peroxide can remove bacteria, viruses and other pathogens in water and ensure the hygiene and safety of drinking water. Compared with traditional disinfectants, it has no harmful by-products residue after disinfection, making it safer and more reliable.
Food-grade hydrogen peroxide is widely used in the food industry and plays an important role in ensuring food safety and improving food quality. However, it must follow regulations when using it to ensure safety.

Diet-grade hydrogen peroxide, which are as follows:
Diet-grade hydrogen peroxide, specially designed for food preparation. Its purity and preparation must comply with food safety regulations. In the process of food processing, it can be used for bleaching, sterilization, and antiseptic purposes. However, its use also requires strict compliance with the dose limit to prevent overuse and harm to food safety and human health. Food is related to people's livelihood, so the supervision and inspection of dietary-grade hydrogen peroxide is extremely strict. From material selection to output, it follows fine procedures to ensure that those involved in food are worry-free.
Pharmaceutical-grade hydrogen peroxide is designed for medical treatment. Its purity and purity are high, far exceeding the dietary grade. In medical practice, it is often used to cleanse wounds, disinfect and sterilize. Because human skin and internal organs are delicate and sensitive, medicinal grade hydrogen peroxide must be prepared to a very high standard, with minimal impurities to prevent irritation of the body, inflammation or other diseases. And the method of medicinal use varies according to the disease and part of the injury. The applicator needs to study the pharmacology carefully and be cautious.
Although both are hydrogen peroxide, they are different in the way they are used, so the grade is determined. The food grade is heavy on food safety, and the pharmaceutical grade is safe for the treatment of serious diseases. Materials, production methods, and quality inspection have their own chapters. The food grade is in food, which can ensure the taste and safety; the pharmaceutical grade is in medical affairs, which can help heal the disease and be healthy. Do not mix, mixed use may cause danger to food safety, or increase the risk of medical illness, be careful.

Food-grade hydrogen peroxide in storage and transportation, need to pay attention to many matters.
When storing, one of them should be placed in a cool and ventilated place. This is because hydrogen peroxide is easily decomposed when heated. If the storage environment temperature is too high, it will cause its stability to decrease, rapid decomposition loss, and reduce the content of active ingredients. If the warehouse is directly exposed to the hot sun, it cannot be used to store hydrogen peroxide, otherwise its quality will deteriorate in a short time. Second, keep away from fire and heat sources. Hydrogen peroxide can easily cause combustion and explosion when exposed to open flames and hot topics. Therefore, fireworks are strictly prohibited around the storage place, and electrical equipment needs to have explosion-proof performance to prevent electric sparks from igniting hydrogen peroxide. Third, it should be stored separately from reducing agents, active metal powders, etc., and should not be mixed. Because reducing agents and active metal powders can react violently with hydrogen peroxide, causing danger. Metal zinc powder, for example, may react quickly if it coexists with hydrogen peroxide, releasing a lot of heat and gas, and even causing the risk of explosion. Fourth, the storage container must be well sealed. Otherwise, hydrogen peroxide is volatile and comes into contact with substances in the air, or causes it to decompose and deteriorate. Common plastic drums, if the seal is not tight, the concentration of hydrogen peroxide will decrease after a period of time.
As for transportation, first of all, the transportation vehicle must ensure that it is clean, dry, and free of other chemicals. To prevent other substances from reacting with hydrogen peroxide and contaminating the goods. If a vehicle that has transported acidic chemicals has not been thoroughly cleaned, hydrogen peroxide will be transported. Acidic substances may interact with hydrogen peroxide, which will affect the quality. Secondly, the transportation process should be protected from exposure to the sun, rain, and high temperature. Vehicles should be equipped with shading facilities and rain-proof cloth. During the high temperature in summer, cooling measures may be taken to avoid the decomposition of hydrogen peroxide due to excessive temperature. Furthermore, light handling should be carried out to prevent damage to packaging and containers. If the packaging is damaged and hydrogen peroxide leaks, it will not only waste goods, but also may cause harm to the surrounding environment and personnel, because it is corrosive to a certain extent. In short, the storage and transportation of food-grade hydrogen peroxide is related to safety and quality, and the precautions in all aspects must be strictly followed.

The safe concentration range of food-grade hydrogen peroxide when used is of paramount importance to dietary safety and human health.
According to ancient books and past practice, food-grade hydrogen peroxide is used in different scenarios, and its safe concentration varies. In the disinfection of food processing equipment and containers, a lower concentration is often appropriate. Generally speaking, its concentration is mostly controlled between 3% and 6%. This concentration can not only effectively kill common bacteria and microorganisms, ensure the cleanliness of equipment and containers, but also do not leave too much residue and endanger food safety.
If it is used for the preservation of specific foods, the concentration control is more stringent. Usually the concentration is maintained at about 0.1% - 1%. This range can delay the oxidation and spoilage process of food, but it will not cause damage to food quality due to excessive hydrogen peroxide, affect the taste and nutritional content, and will not pose a threat to human health.
When using food-grade hydrogen peroxide, it is also necessary to pay attention to the operation method and environmental factors. When operating, ensure that the environment is well ventilated to prevent a large amount of gaseous substances evaporated by hydrogen peroxide from accumulating. Operators should also take good protection to avoid direct contact with the skin and eyes. In case of inadvertent contact, rinse with a large amount of water immediately and seek medical attention as appropriate.
The safe concentration range of food-grade hydrogen peroxide when used needs to be carefully controlled according to the specific purpose, so as to ensure the safety and preservation of food processing, while ensuring the health of consumers.

The impact of food-grade hydrogen peroxide on the environment is related to all ecological things and cannot be ignored.
Food-grade hydrogen peroxide can slowly decompose into water and oxygen at room temperature and pressure. Both are common in the natural environment. Therefore, from the perspective of chemical properties, its decomposition products will not cause long-term and harmful residues to the environment. And it has strong oxidizing properties, and to a certain extent, it can be used for disinfection and sterilization of microorganisms in the environment. In food processing environments, appropriate use of food-grade hydrogen peroxide can effectively reduce the growth of bacteria, molds and other microorganisms, maintain environmental cleanliness, and indirectly protect the surrounding ecological environment from pollution.
However, if used improperly, there are also disadvantages. If a large amount of high-concentration food-grade hydrogen peroxide flows into natural water bodies, although it eventually decomposes into water and oxygen, during the decomposition process, the high concentration of strong oxidation may cause harm to organisms in the water body. Microorganisms and plankton in water may be disturbed by physiological activities, which in turn affects the stability of the food chain of the entire aquatic ecosystem. And in the soil environment, excess hydrogen peroxide may change the soil chemical properties, affect the soil microbial community structure, inhibit the growth of plant roots, hinder the normal development of plants, and affect the balance of terrestrial ecosystems.
Furthermore, the production process of food-grade hydrogen peroxide may have problems such as poor process, poor management, or energy consumption and waste discharge. Energy consumption is indirectly related to environmental problems such as carbon emissions, and improper disposal of waste will also cause pollution to surrounding soil and water bodies.
In summary, food-grade hydrogen peroxide, if used reasonably, has the effect of actively disinfecting and sterilizing the environment; however, improper use may cause negative effects in all aspects of the ecology. Therefore, when using it, be careful to achieve a harmonious coexistence with the environment.
