What is the difference between an iron pan, aluminum pan, stainless steel pan, and non-stick pan?
Pan is the least indispensable kitchen utensil for Chinese people, especially for Chinese cooking, the wok is indispensable. However, there are too many types of works on the market, and many consumers do not know how to choose.
In fact, wok pans are roughly divided into four categories: iron pans, aluminum pans, stainless steel pans, and non-stick pans. Each type has its own advantages and disadvantages. For consumers, health is the most important. Which type to use? Can a wok be the healthiest?
Stainless Steel Pot
Advantages: beautiful and durable. Disadvantages: substandard products with excessive chromium. Stainless steel utensils are beautiful and durable. However, unqualified stainless steel pots will have safety hazards, and their performance is usually excessive chromium.
Hexavalent chromium is listed as one of the chemical substances harmful to the human body, and it is one of the internationally recognized carcinogenic metals. In addition, it should be noted that stainless steel is not completely free of rust. If it is exposed to acids and alkalis for a long time, it will also cause chemical reactions.
Therefore, stainless steel tableware containers should not contain salt, soy sauce, vegetable soup, etc. for a long time; they should not be used to torment Chinese medicine. Reminder: Do not use strong alkaline or strong oxidizing chemicals to wash stainless steel tableware containers to avoid corrosion of the product.
Aluminum Pan
Advantages: excellent heat distribution, lighter pot body Disadvantages: not suitable for high-temperature cooking and a metal spatula. The biggest advantage of the aluminum pan is its excellent heat distribution and lighter pot body. However, inappropriate use of aluminum will dissolve a large amount of aluminum, and long-term excessive consumption of aluminum will accelerate the aging of the human body.
In addition, aluminum pans are not suitable for high-temperature frying. High temperature or collision and friction of metal shovel with the aluminum pan during frying may cause the release of aluminum. The aluminum pan also can not put strong acid and alkali dishes, such as pickled food. Reminder: Aluminum tableware cannot be used with iron tableware. The chemical interaction between the two will cause more aluminum ions to enter the food.
Non-Stick Pan
Advantages: cooking is not easy to stick to the pan. Disadvantages: not suitable for high-temperature frying. The non-stick pan can easily fry and fry food without sticking to the bottom. It can minimize the use of oil, and the kitchen is clean and less oily. In addition, the non-stick pan is easy to clean, and it will be cleaned with a light wipe.
However, ammonium perfluorooctanoate, which is the main raw material of non-stick coatings, will be damaged by dry burning or when the oil temperature reaches 300 degrees Celsius, and the non-stick coating will be destroyed and harmful components will decompose, which is easy to cause cancer.
Generally speaking, the temperature will not reach 260 degrees Celsius during frying, but if the food is fried, the temperature will exceed 300 degrees Celsius. Therefore, try to avoid using non-stick pans when cooking fried foods. Reminder: Don’t use a shovel when cooking in a non-stick pan to prevent damage to the non-stick coating.
Iron Pot
Advantages: It can replenish iron healthily. Disadvantages: easy to rust. Iron pans are traditional kitchen utensils in our country. Generally, they do not contain other chemicals and will not oxidize. In the process of frying and cooking, the iron pan will not have eluted matter, and there is no problem with shedding.
Even if iron is eluted, it is good for the human body to absorb. But iron pans are easy to rust, so it is not suitable to hold food overnight. At the same time, try not to use an iron pan to cook the soup, so as to prevent the rust-free cooking oil layer on the surface of the iron pan from disappearing.
Reminder: Use detergent as little as possible when brushing the pot, and then try to wipe off the water in the pot as much as possible. If there is slight rust, it can be cleaned with vinegar.
