The mechanism of flour whitening agent benzoyl peroxide is that it hydrolyzes and releases active oxygen under the action of air and enzyme Thus, it can oxidize and destroy the conjugated double bond of yellow pigment such as carotene and lutein in flour, and make the unsaturated fat soluble pigment denature and lose color Reasonable use of flour whitening agent will make flour and its products more pleasant in appearance, good in taste, not affect the baking performance of flour, and improve the value of commodities and market competitiveness However, according to the "Hygienic standard for the use of food additives" in China, the maximum amount of benzoyl peroxide is 60ppm, which is 0.06g/kg flour Excessive use of benzoyl peroxide is harmful to human body and flour quality Benzoyl peroxide was added to flour to hydrolyze and release active oxygen, and benzoic acid remained in flour The hydrolysis reaction formula is as follows: benzoic acid enters the human body with food, part of it combines with glycine to form hippuric acid, which is excreted with urine, and part of it combines with zinc gluconate to detoxify Benzoic acid does not accumulate in the body at the normal dosage However, excessive addition is easy to cause benzene accumulation poisoning In addition, the above two detoxification effects of benzoic acid are carried out in the liver Therefore, for people with weak liver function and patients with liver function damage, their biotransformation function is weakened, and their detoxification ability is reduced, leading to liver diseases, which is easy to cause a variety of diseases Many foods use bleach, so is it safe to bleach?
