Non-stick pan can't be used in high-temperature frying. The safe use temperature of non-stick pan should not exceed 26℃. If it is dried or the oil temperature reaches about 3℃, its film may be damaged and the harmful component perfluorooctanoic acid amine will be released. The frying temperature is generally higher. In addition, the thickness of the non-stick coating of the non-stick pan is only about .2 mm, so don't use a shovel when cooking, so as not to damage the coating.

The correct way to use the non-stick pan:

1. Don't use it in high-temperature frying. The main component of non-stick pan coating is polytetrafluoroethylene. If it is heated to about 2 degrees, it will release hydrogen fluoride, a toxic substance. However, since the heating temperature of daily cooking will not exceed 18 degrees, it is harmless when used.

2. Do not use it if it is seriously damaged. If the non-stick pan has only a small part of cuts or scratches, it will not affect the use, but if there is a large area of cracks, it is necessary to consider replacing it.

3. Use a special spatula. Do not use a shovel when cooking in a non-stick pan to prevent the non-stick coating from being destroyed.
