Eating safely and healthily is an important part of the people's good life. It is one of the important contents of the government's work to ensure the people's "safety on the tip of the tongue" with the most rigorous standards, the most strict supervision, the most severe punishment, and the most serious accountability. In February 2019, the Provisions on Food Safety Responsibility System for Local Party and Government Leading Cadres issued by the General Office of the CPC Central Committee and the General Office of the State Council became the first inner-party regulation in China to clarify the food safety responsibilities of local party and government leading cadres, providing a strong system guarantee for ensuring food safety. A data from the National Health Commission shows that, as of June, China has issued 1419 national standards for food safety, including more than 20000 indicators, covering major health hazards in all links from farmland to table, from production and processing to the whole chain of products, to ensure the food safety of the people. In daily cognition, many people turn pale when talking about additives. However, for the modern food industry, according to the definition of the Food Safety Law, food additives are natural or synthetic substances added to food to improve food flavor, anti-corrosion insurance and other needs. Additives have existed since ancient times, and the history of their use is as long as that of human civilization. The main ingredient of brine used in ancient bittern tofu is magnesium chloride, gypsum tofu is calcium sulfate, beer uses carbon dioxide in the production process, and dry red wine uses sulfur dioxide... These are the most common food additives, which meet the needs of food processing and transportation for preservation, preservation, improvement of food properties and flavor, and bring convenience to human life. A basic fact is that China has implemented a more strict approval management system for the management of food additives, and only safe and reliable food additives that are really necessary in technology and risk assessment can be approved for use. Sun Baoguo, an academician of the Chinese Academy of Sciences and an expert in spice and food flavor chemistry, mentioned in a lecture that at present, there are about 2300 kinds of food additives in China, far less than the 15000 kinds approved by countries around the world. In addition, the National Food Safety Risk Assessment Center has strict regulations on which foods can be used and how much each food additive is used. There are also strict requirements for the management and labeling of food additives and the production license of food additives. Therefore, as long as the food additives meet the requirements of the standard, they are safe to use within the scope of the standard. Blind superstition of "zero addition" does not mean safety and health, but it is easy to fall into the trap of some businesses and pay meaningless costs. Of course, the public's concern about food safety and food health deserves to be seen. The questions and expectations behind it are exactly the details of the contradiction between the people's growing needs for a better life and unbalanced and inadequate development
