"Non-stick pan" is a very common pot in the kitchen, because in the process of using less oil consumption, less smoke, but also not easy to paste the problem, so it is welcomed by many people.

In recent years, however, there have been more and more controversies about non-stick pans:

Some people think that non-stick coating will produce toxic substances, can not be used for a long time;

Some people feel that the use of non-stick pan is very convenient, and use for so long, also did not find the body appears any discomfort symptoms. So is nonstick coating really toxic? Can the nonstick pan at home still be used?

Today we'll have a look too.

The reason why the non-stick pan is not stick

The non-stick pan we use is able to do non-stick, the main reason is the coating material on the surface of the pan.

The surface of non-stick pot will use a special coating, this coating has good lubrication performance, and the coefficient of friction is very small, the surface tension is very small, so as to ensure that the non-stick pot in the process of use will not easily adhere to the substance, so it can achieve the effect of non-stick.

The reason why we are willing to choose to use a non-stick pan is because of the characteristics of non-stick.

It is not easy to paste the pan when frying dishes. Even when frying steak or eggs, it is also very convenient to put a little oil and not to stick to the pan.

Is the coating of nonstick pans really toxic?

As we all know, the most important thing about nonstick wok is the coating material used on its surface, but at the same time, the coating material is also the controversy of nonstick wok.

Some people think that the coating used on the surface of non-stick pans will produce harmful substances. If these usually enter the food, it may even lead to poisoning and other symptoms, which will pose a great threat to our health.

So what is the material of the coating of the nonstick pan?

Although the Teflon coating in the nonstick pan will decompose, but the harm to the human body is very small, under normal circumstances, you can rest assured to use the nonstick pan.

The Teflon in the nonstick coating doesn't start to break down until the temperature reaches 300 degrees Celsius.

Experiments have shown that when the temperature reaches the decomposition temperature of Teflon, the decomposition will be carried out, but due to different temperature changes, the decomposed products will be different and the final toxicity will be different.

In our normal cooking process, the temperature inside the nonstick pan rarely reaches 300 degrees Celsius, which means it does not reach the temperature of Teflon decomposition, and does not produce harmful substances.

Usually when we are frying, the temperature of the oil in the pot is generally about 130℃, this temperature is the most suitable for cooking; If the temperature of the oil in the pot has reached 200℃, then the cooking oil has begun to appear smoke;

When the temperature inside the pan reaches 300 degrees Celsius, the temperature at which Teflon breaks down, the fumes are already choking.

When we fry vegetables, the temperature of the oil simply cannot reach the temperature of Teflon decomposition. Naturally, it will not produce harmful substances, which will not pose a threat to our health.

And even if it has reached the decomposition temperature, in the pot has begun to smoke, we will not continue to cook, so these harmful substances will not enter the food.

[Problems to pay attention to when using a non-stick pan]

Try to avoid dry burning

Although it is said that in the normal use of non-stick pan will not decompose harmful substances, but we also need to pay attention to avoid interference, in the case of dry pot temperature will be relatively high, so it may damage the service life of non-stick pan.

After the coating falls off, it is necessary to replace the nonstick pan in time

The coating inside the nonstick pan is not particularly strong. If the spatula used at ordinary times is relatively hard, or the cleaning cloth used is relatively hard, it may cause damage to the internal coating.

After the problem of falling off the coating inside the non-stick pan, it is suggested that you should replace the new non-stick pan to avoid falling off the coating into the food, which will have an impact on health.

Summarize

To sum up, under normal circumstances we can continue to rest assured to use non-stick wok, but we must pay attention to avoid dry burning when using non-stick wok, try to control the temperature of the stir-fry, and when the coating falls off the problem, it is best to replace the non-stick wok in time.
