Non-stick cookware: What makes it both safe and durable?

What factors do non-stick cookware's security performance have to do with?

The safety of non-stick cookware mainly depends on the coating material and the use temperature control. Mainstream food-grade coatings need to have stable chemical properties and will not release harmful substances at normal cooking temperatures, but when the temperature exceeds 260°C, the coating may begin to decompose. Therefore, it is crucial to avoid drying the empty pot - drying the empty pot for a few minutes will cause the temperature at the bottom of the pot to soar above 300℃, directly damaging the coating. In addition, the integrity of the coating also affects safety. If the coating occurs in large areas of damage, it should be stopped immediately to prevent the coating particles from mixing into the food. The safety of the material is also reflected in the pot body substrate. The high-quality substrate does not contain harmful heavy metals such as lead and cadmium, and is closely combined with the coating, making the coating not easy to fall off.

How to extend the service life of non-stick cookware?

The durability of non-stick cookware is directly related to usage habits, and the core is to avoid coating damage. When choosing cooking tools, you need to avoid metal shovels and steel wool balls, and use soft tools such as wooden shovels and silicone shovels. Use soft cloth or sponge when cleaning to prevent hard objects from scratching the coating. In terms of temperature control, the habit of "putting it in the pot after smoking" should be avoided. If the oil temperature reaches 60% heat (about 180℃), the ingredients can be put into it, which not only meets the cooking needs, but also protects the coating. In addition, it is not advisable to rinse the hot pot immediately after frying the dish. As quenching may cause the coating to crack due to thermal expansion and contraction, the pot should be cooled before cleaning. During daily storage, avoid stacking of pots, or place a soft cloth on a stack to prevent friction on the bottom of the pot from damaging the coating.

How to judge the quality of non-stick cookware?

To identify the quality of non-stick cookware, you can judge through appearance inspection and actual user experience. In terms of appearance, the surface of the high-quality coating is smooth and even, without bubbles, scratches or missed areas, the edges of the pot are polished and smooth, and there are no burrs; the thickness of the substrate is uniform, and the feel is stable when weighed, without obvious deviations in light and heavy. In actual use, heating uniformity is an important indicator - if the pot bottom is locally overheated, it will not only affect the cooking effect, but also easily lead to accelerated local coating aging. In addition, the coating of high-quality pots has strong adhesion. After many cooking and cleaning, the coating is lightly scraped with nails without any signs of falling off, and there is no odor. It should be noted that compliant products will clearly indicate the coating type and temperature range, which can be used as a quality reference.
