Is not contaminated with pot paint toxic

After investigation, it is found that there are many kinds of Non-stick surface on the market today, including quality Non-stick surface, aluminum Non-stick surface, stainless steel Non-stick surface, alloy steel Non-stick surface, etc., and the prices are different. The cheaper ones are tens of dollars, and the more expensive ones are thousands of dollars. The interviewees said that the reason why they chose to use Non-stick surface was that it would not stick to the bottom of the pan when frying, so it could keep the original taste of the ingredients and was easier to clean.
However, through quality sampling inspection, it is found that some Non-stick surface do not meet the national standard QB-T2421. Among the sampled products, 35% of non-conforming items are mainly concentrated in the thickness of the non adhesive layer and chemical indicators.
Experts said that the coating of Non-stick surface is called Teflon, which is mainly made of polytetrafluoroethylene and is chemically inert. Because of its good lubricity and low friction coefficient, this coating is often used on kitchen utensils such as Non-stick surface. Eating a small amount of Non-stick surface coating by mistake will be excreted by the human body, which is harmless to health.
However, if encountering high temperature, the polytetrafluoroethylene contained in the Non-stick surface coating will decompose phosgene, which will strongly stimulate the lungs, thus leading to the occurrence of Emphysema. Generally, the denaturation temperature of Non-stick surface coating is 260 ℃, and the decomposition temperature is 350 ℃. Phosgene will be decomposed when the temperature reaches above 350 ℃.
When cooking, as long as you do not dry burn the Non-stick surface, it will not reach the decomposition temperature, and you can cook normally.
Therefore, we conclude that the Non-stick surface coating itself will not cause cancer. Only when the temperature reaches 350 ℃ or above, the coating will decompose harmful substances, which will affect the health of the body with food intake.
