Food grade hydrogen peroxide (H2O2) is widely used in food processing such as dairy products and dried tofu as a disinfectant and bleaching agent. The Ministry of Health GB2760-1996 has strict control over the use range, region and amount of hydrogen peroxide, and stipulates that detection of hydrogen peroxide is not allowed in the final product. In addition, the European Pharmacopoeia stipulates a limit of 10 ppm for peroxides under "gelatin". The limit of this item in my country's medical gelatin light industry standard QB2354-2005 is also 10ppm.
It should be said that peroxides are almost non-existent in the formal production of edible and medicinal gelatin. If the content exceeds 10mg/kg, it can be judged that it was added artificially during the glue making process. Some factories have poor sanitary conditions. In order to prevent corrosion or make the gelatin whiter, hydrogen peroxide is added to the glue. There are reports in the literature that some factories can detect hydrogen peroxide containing hundreds or even thousands of mg/kg in dry glue. Some factories even add industrial grade hydrogen peroxide, and industrial grade hydrogen peroxide contains a certain amount of anthracene, quinone and heavy metals. Harmful impurities. Anthracene and quinone are carcinogens that have been identified in science, so they can only be used in papermaking, printing and dyeing industries.
In recent years, continuous research has suggested that the oxygen free radicals in the body damage lipids, DNA, proteins, etc., and may directly cause some chronic cardiovascular and immune system diseases or the occurrence of aging. Based on this understanding, people have gradually begun to use some antioxidants, such as beta carotene, grape seed extract, VitE, etc. to balance peroxides and delay aging. Therefore, the peroxide residues in the gelatin hollow capsules may cause harm to the human body.
