1. Iron pot
Iron pot is a traditional pot. Its material does not contain other special chemicals, and its antioxidant capacity is relatively strong, so it will not produce some inedible substances during cooking. At the same time, the iron pot is rich in iron ions, which will dissolve into food during cooking. People can absorb iron and synthesize hemoglobin after eating, which can prevent iron deficiency anemia to some extent. But iron pots are divided into the following two types:
1. 1 wok
Raw wok is easier to master the heat and suitable for slow frying. Its design is usually that the bottom of the pot is thick and the wall of the pot is thin and heavy, so the heat transfer speed is slow. Although the heat transfer speed is slow, it also has its own advantages, that is, pure iron. If you cook with this pot, you can supplement iron for human health.
1.2 fine iron pot
Compared with raw wok, fine wok is more suitable for fire and stir-frying. Forged with black iron sheet or hammered by hand, the surface is treated multiple times, so the pot body is very light and not heavy at all. The temperature of the fire can be directly transferred to the food through the pot, and the heat transfer speed is very fast.
Although the iron pot has the advantages of durability, uniform heating and outstanding heating effect, its disadvantages are undeniable. Ordinary iron pots are prone to rust. If rust is accidentally ingested by the human body, it will cause damage to the liver. The weight of the pot is a big problem for some food lovers who have little wrist strength but want to cook.
How to choose iron pot
So I suggest that if you want to choose an iron pot, you'd better buy a thin iron pot, because the thin iron pot is relatively light, which is very suitable for women to cook at home at ordinary times, and the heat transfer speed is very fast, especially in the kitchen in summer. However, thin iron pots are more suitable for cooking. I want to stew some fish soup or something, but I can't do it in a fine iron pot. At this time, you need to prepare a raw iron pot, and the soup that comes out slowly will be delicious and nutritious. But no matter what type of wok it is, we should pay attention to its cleanliness to prevent rust from affecting people's health.
2. Stainless steel wok
Compared with the iron pot, this kind of pot is lighter. Although light, it is also strong. Stainless steel pot is not only stable, but also has sufficient strength and plasticity. Stainless steel pot is not easy to rust and easy to clean because it has a solid oxide film on its surface. Even if it is used for a long time, it can still maintain a beautiful face.
Although this type of pot is very light and can prevent rust, it also has two disadvantages. First, the insulation effect in stainless steel pot is relatively poor. If you want to use stainless steel pot to hold food in winter, it will soon get cold when your husband or children come home from work, so it needs constant heating, so this is a very troublesome thing; Second, compared with the traditional iron pot, its price will not only be much higher, but also will not play a role in supplementing iron to the human body.
3. Alloy wok
Most alloy workpieces are aluminum alloy products, and only a few are titanium alloys. The surface of alloy pot is fully oxidized, so it has good corrosion resistance and strong wear resistance. Moreover, such pots are often light and durable, and the biggest advantage is uniform heat conduction, rapid heating and non-sticking.
But we all know that aluminum is harmful to human body. Even if aluminum pot is synthesized, aluminum products will precipitate during heating. Therefore, if aluminum alloy pots are often used, especially when making food containing acid or alkali, aluminum is easily dissolved in food, which will hinder the energy conversion process of human cells.
