Is non-stick pan poisonous?

In our lives, many of our friends still have iron pans as cooking tools at home. Although iron pans are relatively safe for us, they may not be convenient to use. For example, when cooking in an iron pan, the food may stick to the bottom of the pan. So some of our friends may choose to use non-stick pans. So, are non-stick pans toxic? This is what many friends want to ask. Let's take a look at it together.

The reason why non-stick pans can function as non-stick pans is mainly because a special Teflon material is added to the bottom of the pan. This material is not good for our human health. Let us understand the specific reasons together. I hope that all friends can pay attention to it.

Is non-stick pan toxic?

The main raw material of non-stick pan coating is polytetrafluoroethylene. According to the national mandatory standards, polytetrafluoroethylene coating is made of polytetrafluoroethylene as the main raw material and certain additives. It is applied to the surface of metals such as aluminum and iron plates and sintered at high temperature. It is used as an anti-stick coating that comes into contact with non-acidic food containers. The use temperature is limited to below 250°C.

Polytetrafluoroethylene can withstand high temperatures of 400 degrees, but its chemical properties begin to become unstable above 200 degrees. It will immediately catch fire and burn above 400 degrees, releasing hydrogen fluoride gas. The solution of hydrogen fluoride dissolved in water is called hydrofluoric acid, which is not only highly corrosive (hydrofluoric acid is widely used in glass etching process), but also highly toxic.

Currently, no matter what form the non-stick pan appears in or which country it is produced in, its main material is Teflon, and advanced ones are mixed with antioxidants and stabilizers to improve the high temperature resistance of polytetrafluoroethylene. In short, no matter what they are called or what substance they are, their main ingredient is polytetrafluoroethylene.

Although the maximum temperature during cooking will not exceed 180 degrees, the Teflon coating will always decompose little by little under the condition of friction heating. A non-stick pan with a very long lifespan cannot be used for frying, stir-frying, or grilling pizza. At most, it can be used for stewing porridge or something like that. In this case, the loss of polytetrafluoroethylene can be reduced to the lowest level, and the harm to the human body is also the smallest.

If you buy a non-stick pan, do not use it for frying, stir-frying, deep-frying or baking. After all, accelerating the volatilization of Teflon material is not good for your health.

I believe everyone should now have their own answer to the question of whether non-stick pans are toxic. In our lives, for our own safety we should try to use iron pans and not damage our health for the sake of temporary convenience. I hope that friends who are currently using non-stick pans can use them as little as possible to make our lives healthier.
