What material is good for wok?

Thermal conductivity of silver in metal >: copper >: aluminum > iron >: The prices of stainless steel, silver and copper are relatively high, and there are few woks made of these two materials in the market, and the patina dissolved by copper is still toxic and generally not used. The remaining aluminum and iron have moderate thermal conductivity, but it is easy to sprinkle aluminum when cooking with aluminum pot, which is harmful to health.

Although the thermal conductivity of iron is not as good as that of aluminum, in the process of cooking, the iron pot does not contain other chemicals, will not be oxidized, and there are few dissolved substances. Even if a small amount of iron is dissolved from iron, it is good for human body.

Therefore, from a health point of view, it is best to choose an iron pan for cooking, which can not only reduce the loss of vitamin C in vegetables, but also directly supplement iron, which is of great benefit to prevent iron deficiency anemia.

Extended data

Generally, wok products on the market will be subdivided into raw wok and refined wok, with some differences in characteristics:

Raw wok is suitable for slow frying, and the iron is pure, which can supplement iron healthily. The design at full capacity is thin bottom weight. When the temperature of the fire exceeds 200℃ during the heating process, the raw wok will control the temperature transferred to the food at about 230℃ by emitting certain heat energy, which makes it easier to control the temperature. Friends who like slow frying can buy it.

Fine iron pot is suitable for fire and stir-frying. Forged from black iron sheet or hammered by hand. Its surface is usually treated many times, which makes the pot lighter and lighter. It can directly transfer the temperature of the flame to the food through the pot.
