According to research, the coating on the surface of non-stick pan contains a substance Teflon, which is not very toxic, but some unscrupulous merchants will add a substance, namely ammonium fluooctanoate, to the coating in order to reduce the cost. This substance is very dangerous to human health. Many experiments have proved that this substance can obviously delay the development and growth of consumers, and it will also have a great impact on the nervous system, reproductive system and immune system. Even some animals die prematurely and even become cancerous after eating this chemical by mistake.
When buying this kind of non-stick pan, you must go to a regular store to buy a non-stick pan that meets the national standards. Because the melting point of Teflon is relatively high, and the temperature that can be reached by cooking is far from its melting point factor, as long as it does not exceed a specific range, it will not cause harm to health. In addition, although Teflon has strong high temperature resistance, if the dry pan is burned for a long time, the surface temperature of the non-stick pan can be as high as 800 degrees, which will cause Teflon to decompose isobutylene, which will lead to dangerous situations such as cancer.
Therefore, when using the non-stick pan, we must pay more attention to the coating of the non-stick pan, replace the non-stick pan in time after using 1~2 years, and do not scrape the coating of the non-stick pan with a steel shovel or shovel when cooking, otherwise the coating will easily fall off and harmful substances will decompose. Moreover, it is necessary to observe whether the coating surface is smooth when buying the non-stick pan again, which can effectively reduce the harm of the non-stick pan to the human body.
