Hydrogen peroxide can also be called hydrogen peroxide, chemical formula H2O2. It has a wide range of uses, and can be divided into three types: medical, military and industrial. From the news, we often see unscrupulous businessmen using hydrogen peroxide/hydrogen peroxide to treat spoiled raw materials and make unqualified food. Hydrogen peroxide/hydrogen peroxide produces high vigilance. So, can hydrogen peroxide/hydrogen peroxide be used in food processing, and how to effectively ensure table safety?
Pure hydrogen peroxide is a light blue viscous liquid. Medical hydrogen peroxide can be used for daily disinfection; it can also be used for industrial hydrogen peroxide hydrogen peroxide, food grade hydrogen peroxide hydrogen peroxide, and reagent grade hydrogen peroxide; it can be miscible with water in any proportion. A strong oxidant, the aqueous solution is commonly known as hydrogen peroxide, which is a colorless, odorless, transparent liquid with no residue after sterilization, so it is widely used in the food industry, such as packaging materials and production pipelines for beverages, drinking water, beverages, beer, etc. Disinfection, as well as for Surface disinfection and sterilization of meat, aquatic products and other foods.
But everyone can rest assured that because there have been cases of being sentenced for using hydrogen peroxide, most of the charges were "production and sale of poisonous and harmful food crimes". Coupled with extensive media reports, the concept of "hydrogen peroxide is poisonous" has been deeply rooted in the hearts of the people. Of course, quite a few of them use industrial hydrogen peroxide, and some of them also use illegal substances such as formaldehyde and industrial caustic soda, which is not food-grade hydrogen peroxide in the true sense.
According to quarrz, in the new version of food additive standards issued in 2014, hydrogen peroxide for food has obtained the legal status of "processing aid", and the residual amount does not need to be limited. After that, hydrogen peroxide was approved as a preservative, but it was only allowed to be added to fresh milk to keep it fresh. Subsequently, hydrogen peroxide became a processing aid, and its use was expanded to various types of food, but it was no longer used as a preservative. During the period, the relevant standards for hydrogen peroxide used in food additives were deleted, but considering its obvious functions such as disinfection and sterilization, in the fourth edition (2014) the standard had to restore its status as a food additive, and it was still used as a processing aid .
So, since hydrogen peroxide can be used as a processing aid, how can we better ensure its safety? According to the relevant provisions of the "Hygienic Standards for the Use of Food Additives", food-grade hydrogen peroxide is allowed to be used as a processing aid in food production. It should be cleaned up before it is made into a product. If it cannot be removed, it should be strictly controlled within the specified range. According to relevant personnel, since most food additives have strict usage limit requirements. Generally speaking, the mass fraction of hydrogen peroxide after rectification is 30%-35%. However, food processing enterprises can dilute it according to the actual mass fraction of the product and the use requirements before use, and cannot add it blindly.
In addition, relevant departments should strictly strengthen market supervision and control the content of products through advanced food testing instruments, such as AU-300C/AU-300HP hydrogen peroxide density detector, hydrogen peroxide concentration tester, constant temperature density, and concentration tester. It mainly uses high-precision measuring sensors imported from Germany. According to the GB/T 1616-2014 standard specification, the density value SG is measured first, and then the hydrogen peroxide concentration % is automatically calculated from the density value. It is widely used in the upstream production of hydrogen peroxide, the downstream purchase of hydrogen peroxide, and medicine. Industry, chemical industry, printing and dyeing industry, electroplating industry... and other industries, has become necessary physical and chemical testing instrument for major chemical product manufacturers! Stronger for weak signals and anti-interference ability, which can ensure the stability and reliability of the detection results.
At the same time, the response speed is fast, stable, and has a long service life. In addition, the instrument has the characteristics of high efficiency, high speed, and high sensitivity, which can effectively ensure the accuracy of the detection results. It has the function of automatically calculating the temperature compensation coefficient in any temperature range, without manual calculation, temperature range: 0~99.9℃; in addition to the automatic calculation of temperature compensation coefficient, the temperature coefficient can also be manually input, compensation range: (0.00001~9.99999)/ ℃; with air buoyancy compensation function and weight volume thermal expansion coefficient compensation function.
Generally speaking, there is almost no pollution in the production and use of hydrogen peroxide, and it is a recognized "green chemical" disinfection and sterilization product. There is also a standard basis for the use of hydrogen peroxide in food processing, and it is a legal food processing aid. If used properly, it is definitely a "good helper" for the food industry. AU-300C/AU-300HP/hydrogen peroxide detector can accurately detect "problem products" and prevent them from flowing into the market. It can control product quality and cost more efficiently. It is an essential physical and chemical testing instrument for major chemical product manufacturers! And play an important role in the detection and supervision.
