It is understandable to care about our food safety, but whether flour whitening agent is harmful to human body should have scientific basis and can't talk nonsense. At present, most of the harmful reports about flour brighteners in China can be said to be hearsay, and no scientific basis has been found so far. On the one hand, news plagiarism, on the other hand, some departments irresponsibly exaggerate a non-existent food safety problem in order to show their political achievements of caring about public food safety, which not only causes public anxiety and panic, but also misleads government departments to waste a lot of manpower and financial resources. This man-made food safety behavior is also an irresponsible mistake to the public. Toxicological research was conducted in Korea, and the Organization for International Economic Cooperation and Development (OECD) published a detailed toxicological assessment report on benzoyl peroxide (Siam 15 SIDNIAL Assessment Report-Boston, USA, 2002122-25 October). This report discusses in detail that benzoyl peroxide has no genotoxicity and carcinogenicity to human body.
