As the saying goes: "People have been eating as the sky." In recent years, our food safety environment has become increasingly severe. With the continuous emergence of poisonous milk powder and dyed steamed buns, people can't help asking, is food additives safe?

Food additives refer to the chemical synthesis or natural substances approved by the state to add chemical synthesis or natural substances in food due to the need for anti -corrosion and freshness. my country's "Sanitary Standards for Food Additives" is divided into more than 1,500 types of 22 categories such as preservatives, coagulants, quality modifiers, flavors, and nutritional enhancers. When human food enters industrialized production, there are almost nothing except a few natural wild foods. At present, nearly 97%of foods use various additives. It can be said that food additives have become an indispensable material in the production of modern food industry.

Food additives are very obvious on the anticorrosive freshness and preservation of food. According to food safety requirements, the total number of bacteria per gram of food cannot exceed 80,000. If no preservatives are used, even in the low -temperature environment of 0-4, the total number of bacteria will exceed 100,000 per gram of meat products on the fifth day. And preservatives can curb a large number of botulinum -like sporebacteria in meat products, effectively extend the shelf life of meat products.

Food additives can not only preservation and freshness, but also improve the appearance and taste of food. The sourness, sweetness, and freshness of food are usually not naturally owned by food, and they are often "tuned" by additives. The temptation of food, such as the elasticity of the noodles, and crispy snacks, are mostly the credit of additives.

Now, people have found that many food additives also have the function of preventing and disease -resistant. For example, rotten red tunes are fermented by rice, which can reduce blood lipids. It is both pigment and functional additive; the sweetener extracted from licorice can improve the liver function; The role of liver and anti -dental caries.
