What are the healthy pots and pans? What should I pay attention to in use?
1, iron pot, which is the most traditional and considered the safest kitchen utensil, contains no other chemicals, and some WHO experts believe that cooking with iron pot is the most direct iron supplement method, which is very beneficial to children and menstruating women. But for the elderly who are not in danger of iron deficiency, it is best not to cook in an iron pan.
When cooking in an iron pan, you need to pay attention to: after each cooking, dry it with a rag to avoid rust; Try not to use an iron pot to make soup; Don't use it to hold vegetables overnight, otherwise the iron pot will dissolve out under acidic conditions and destroy vitamin C; Use detergent as little as possible when brushing the pot; If rust is found, make it clear with vinegar; And don't cook mung beans in an iron pot.
2, stainless steel pot, the biggest problem of this kind of pot is how to choose, unqualified products are easy to exceed the standard of chromium, which is one of the internationally recognized carcinogenic metals. Therefore, you must not be greedy and cheap when buying stainless steel pot, but choose products from big factories with higher safety factor.
Do not hold salt, soy sauce, soup, etc. during use. For a long time, and don't contact with acid and alkali substances for a long time, otherwise chemical reactions will occur. When washing the pot, use detergent as little as possible to avoid corrosion.
3. Non-stick pan Non-stick pan is easy to use, that is, it does not stick or paste and does not rust. However, more attention should be paid to whether the surface coating quality is qualified or not.
When using a non-stick pan, you should pay attention to the following points: First, it is not advisable to fry food at high temperature. In general, if the temperature exceeds 260 degrees, the surface coating will be destroyed and harmful substances will be released; Secondly, you can't use a shovel when cooking, otherwise it will destroy the coating, and in this process, it is easy to decompose carcinogens and affect the use.
4. Casserole Casserole is generally the first choice for soup, which has the characteristics of slow heat dissipation and good heat preservation effect. The lead content of unqualified casserole is easy to exceed the standard, and long-term use can easily lead to lead poisoning.
Casseroles should not contain acidic food, because acid will lead to the dissolution of lead and cadmium. At the same time, taking advantage of this feature, when buying casserole, you can soak it in edible vinegar water and boil it, so as to dissolve harmful substances in advance and avoid the harm caused by the use.
Which pots are not recommended?
In general, we mainly use stainless steel or non-stick pans, which are the four kinds mentioned above. However, aluminum pot and copper pots are still used in a few rural areas, which may easily lead to human poisoning and are not recommended.
In aluminum pot, experiments show that when aluminum pot is used, the aluminum content in the prepared food will increase whether it is fried or boiled. In addition, when aluminum pot is cooking, aluminum will be released to some extent when the metal shovel collides with aluminum pot, which is harmful to human body. Also, don't use aluminum pot to package pickled food, because the acid or alkali in this kind of food can easily react with aluminum and produce substances harmful to human body.
Copper pots, generally speaking, are rarely used. The copper pot specially used for cooking will have a stainless steel inner layer, so you must be alert to the damage of the inner layer when using it, otherwise it is easy to be poisoned. It should also be noted that if rusty copper tableware is found, it must not be used, because copper rust is toxic and will cause cancer.
In a word, pots and pans also play a vital role in human health, so we must pay more attention when using them. In addition, the oil temperature should not be too high when cooking (don't wait for smoke before putting chopped green onion, vegetables, etc. ). In the practice of cooking, some middle-aged and elderly friends can cook more steamed vegetables. In short, keeping in good health is a constant topic in life.
