What are the standards that a qualified preservative should have?
Nowadays, the use of preservatives is more and more extensive, whether it is in food, or in medicines, pigments, lotions, etc. Its main function is the growth and reproduction of microorganisms to achieve the effect of extending the shelf life. Then, when purchasing, you should meet the following criteria.
When it comes to preservatives, everyone often thinks that they are harmful. In fact, as long as they are within the scope of safe use, there is no problem. Taking food preservatives as an example, according to my country's regulations on the use of preservatives, the following standards should be met:
1. Within the scope of reasonable use, it will not cause harm to the human body
2. Food preservatives do not affect the flora of the digestive tract
3. It can be degraded into the normal components of food by itself in the digestive tract
4. Does not affect the use of antibiotics
5. When heat treatment of food, no harmful ingredients will be produced
Therefore, as long as the preservatives are used properly and within the scope stipulated by the state, they will not cause any harm. Conversely, if preservatives are not used, bacteria can grow, and the consequences will be more serious.
