Sudan red, clenbuterol, melamine, when it comes to food additives, people first think of these. Many people therefore "talk about additive discoloration". "In fact, they are not food additives, but illegal food additives." On November 24, Sun Baoguo, an academician of the CAE Member, chairman of the China Food Science and Technology Society, and president of Beijing Technology and Industry University, said in an interview with the Science and Technology Daily. Fan Zhihong, a professor in the School of Food Science and Nutrition Engineering of China Agricultural University, believes that the public's talk about the color change of food additives is more due to the confusion of the concepts of illegal additives and food additives. Illegal additives are not food additives. "The legal use of food additives is safe. So far, none of the food safety incidents that endanger human health in China are caused by the legal use of food additives." Sun Baoguo said. In 2008, the "melamine" incident shocked the whole country. At that time, some experts said that "melamine is not a good food additive", which suddenly attracted the public's attention. "Melamine is not a food additive at all, but an illegal additive. But since then, there have been false rumors, followed by Sudan red and clenbuterol. Some people mistook these illegal food additives for food additives, so food additives have been blamed." Sun Baoguo was helpless about this. In Fan Zhihong's opinion, we must distinguish the relationship between rational use of food additives, abuse of food additives and illegal addition. She explained that reasonable use means meeting the requirements of national standards on the scope and amount of its use, as well as the use principles of food additives. It is illegal to abuse food additives if the use scope exceeds the national standard, such as lemon yellow in dyed steamed bread, or the use amount exceeds the national standard, which is often said to exceed the standard, or violates the use principle of food additives, such as using essence to pickle duck meat and forge beef and mutton. "Melamine, Sudan red, formalin, etc. are all illegal additives. China's food safety law clearly stipulates that the production and operation of 'food produced with non food raw materials or food added with chemical substances other than food additives and other substances that may harm human health' is prohibited." Cao Yanping, a professor at the School of Food and Health of Beijing Industrial and Commercial University, said. Fan Zhihong said that, in addition to safety, improper use of food additives also involves shoddy goods and counterfeiting. For example, using chicken essence and emulsifier to pretend to be the real chicken broth will not cause security problems, but it is cheating consumers and unfair competition. At the same time, relevant experts pointed out that the illegal acts of "two excesses and one non", such as the use of food additives beyond the scope and limit, and the addition of non edible substances, are the causes of food safety problems. "The use of food additives and the addition of non edible substances beyond the scope and limit must be severely punished according to law," Sun Baoguo stressed. Less than one sixth of the food additives approved by China in the world may be contrary to the understanding of the majority of the domestic people. China is very strict in the approval management of food additives. At present, there are about 15,000 kinds of food additives approved in the world, and only 2300 kinds in China. Cao Yanping introduced that according to the provisions of the Food Safety Law, I
