Different pots have their own advantages and disadvantages, and they should be selected according to the ingredients and uses.

1, iron pot is the safest pot at present.

Iron pots generally do not contain 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.

2, non-stick pan should not be fried at high temperature.

The non-stick pan coating is actually a film with a thickness of about 0.2 mm, which may be damaged if it is dried or the oil temperature reaches above 300 degrees Celsius. Generally speaking, when cooking, the temperature will not reach 260℃, but if it is fried food cooking, the temperature may exceed 260℃. Do not use a non-stick pan when frying food. Stir-fry in a non-stick pan instead of a shovel to avoid damaging the coating.

Porcelain pots used to be recognized as non-toxic tableware, but the glaze color of some inferior porcelain tableware contained lead. Long-term use of products with excessive lead and cadmium dissolution will cause heavy metal poisoning and seriously affect health.

The inner wall of the casserole is colored, so it is not suitable to store wine, vinegar, acidic drinks and food. When buying enamel tableware, the surface should be smooth, the enamel should be uniform and the color should be bright.

5. It is not suitable for stainless steel pot to fill salt for a long time. Stainless steel utensils are beautiful and durable, but unqualified stainless steel pot may have excessive chromium. Hexavalent chromium is listed as one of the chemicals harmful to human body and one of the internationally recognized carcinogenic metals.
