The newly bought iron pot is soaked in salt water. Then sprinkle with salad oil to wipe. If it still smells, cut it into pieces with ginger, heat it in a pan and wipe it clean. It is best to use an iron pan. No pollution, uniform heating. Cooks use iron pots. ?

Recently, experts from the World Health Organization began to suggest the use of iron pans, which are traditional kitchen utensils in China and generally contain no other chemicals and will not be oxidized. In the process of frying and cooking, there will be no dissolved substances in the iron pot, and there is no problem of falling off. Even if the iron substance is dissolved, it is beneficial to the human body to absorb it. WHO experts even believe that cooking in an iron pot is the most direct way to supplement iron.

The role of iron pot

Iron pots rust easily and are not suitable for overnight food. At the same time, try not to use an iron pot to make soup, so as to avoid the oil layer on the surface of the iron pot disappearing and rusting. When you brush the pot, you should also use detergent as little as possible, and then try to clean the water in the pot. If there is slight rust, it can be cleaned with vinegar.

Non-stick pan: not suitable for high-temperature frying. The main culprit of this Teflon storm is ammonium perfluorooctanoate, the main raw material of non-stick pan. Ammonium perfluorooctanoate is a synthetic fluorine-containing polymeric acid. Because of its high stability, it is not easy to adhere to food, and it is an essential production material for non-stick pan coating. This non-stick coating is actually a film with a thickness of about 0.2 mm. ..

If dry burning or oil temperature reaches above 300 degrees Celsius, this film may be damaged. Generally speaking, when cooking, the temperature will not reach 260℃, but if it is fried food cooking, the temperature may exceed 260℃. ?

As a reminder, many dishes need to be fried when cooking. The boiling point of oil is 320℃. When frying food, the oil is always boiling hot, which easily leads to the decomposition of harmful components in the non-stick pan. Therefore, non-stick pans should be avoided when cooking fried and fried foods. In addition, use a non-stick pan instead of a shovel to stir-fry to prevent the coating of the non-stick pan from being damaged.
