With the enhancement of increased coverage and health awareness, flour brightenerhas been ordinary consumers attention.
Whitening mechanism brightener is oxidant release oxygen atoms, by oxidation ofcarotene, yellow pigment, so that the flour brightener. At present, the whitening agentused is the benzoyl peroxide. Generation after the decomposition of benzoic acidresidue in the flour, and with the food made from entering the human body. In the human body, the majority of benzoic acid in 9 - 15 hours and glycine combine to formhippuric acid from the urine excreted, rest and glucose acid compounds and detoxification. Experiments show that: benzoic acid in the body is not. Flour brightening agent, benzoyl peroxide (BPO), effective components called diluted benzoyl peroxide. It is our country the eighty's of the last century from abroad andbegan the widespread use of food additives in wheat flour. It is mainly used to bleach flour, flour and accelerate the ripening.
But the expert reminds everybody: benzoic acid of these two kinds of the detoxification process is carried out in the liver. Therefore on the liver function ofweak people, benzoic acid may be inappropriate for the. Long term consumption ofwheat flour and its manufactured goods containing excessive whitening agent, can cause chronic benzene poisoning, harm to human health. According to China's"Hygienic Standards for uses of food additives" (GB2760-86) regulations, the maximum amount of benzoyl peroxide in flour is 60PPM, or 0.06 g / kg of flour.

Effect of food additives in food industry everybody be obvious to people, have occurred in the past some of the food safety accident let everyone misunderstandingof food additives, but in fact, as long as the addition of food additives in accordance with the relevant standard of right for the production, it is not a problem, the food safety accident of the past are due to the addition of non food additives or excessive add to lead to. This is also the reason why the flour brightener introduced from abroad and allowed in china. So now there are some problems, does not lie in theflour brightener itself, but in the present enterprises lack of self-discipline and the related departments of the regulation is not in place -- excessive add or add illegal substances or found no problem that leads to the occurrence of food safety incidentsin supervision. So whether to ban added is not a problem, if the relevant standardslag behind social development on the amendment of the corresponding standards,such as standard no problem to ensure the food safety, the question is to strengthen the self-discipline of enterprises, food production enterprises must be strictly in accordance with the relevant standards of production; the relevant departments to strengthen supervision, Cengcengbaguan, to ensure that consumers hands is the food safety!
