The wok is a must in family life, and almost every housewife will use it. So how can I buy a new wok if it breaks down when using it? The following is the selection of the wok I arranged for you, hoping to help you.

Selection of wok

1. Iron pot: the safest pot at present

It is reported that the traditional iron pot in China is the safest kitchenware at present. Qualified iron pots are made of pig iron, which generally does not contain other chemicals and does not cause oxidation problems. In the process of cooking and cooking, there will be no dissolved matter in the iron pot, and there will be no problem of falling off. Even if iron is dissolved, it is beneficial for the human body to absorb it.

It is reported that WHO experts also recommend the use of iron pots. The main reason is that the iron pot has a good auxiliary effect on the prevention and treatment of iron deficiency anemia. Because of the action of salt and vinegar on iron at high temperature, and the friction of spatula and spoon, the inorganic iron on the inner surface of the pot is desquamated into powder with small diameter. After being absorbed by the human body, these powders are transformed into inorganic iron salts under the action of gastric acid, thus becoming hematopoietic raw materials for the human body and playing its auxiliary therapeutic role. Many foods contain iron, but iron supplementation in iron pots is the most direct.

Reminder: Ordinary iron pots are prone to rust. If the human body absorbs too much iron oxide, that is, rust, it will do harm to the liver. Experts said that iron pots are easy to rust and it is not suitable to hold food overnight. At the same time, try not to cook soup in an iron pot, so as to avoid the disappearance of the oil layer on the surface of the iron pot to protect it from rust. When you brush the pot, you should also use detergent as little as possible to prevent the protective layer from being brushed out. After brushing the pot, try to wipe the water in the pot to prevent rust. If there is slight rust, it can be cleaned with vinegar.

2. Pots made of other materials

1. Non-stick pan: It is not suitable for frying at high temperature

According to experts in environmental chemistry in China, ammonium perfluorooctanoate is an artificial fluorine-containing polymeric acid. Because of its high stability, it is not easy to adhere to food, so it is a necessary production material for non-stick pan coating. This non-stick coating is actually a film with a thickness of about .2 mm. If it is dry-burned or the oil temperature reaches 3,

It is understood that when the non-stick pan is used, if the temperature reaches 26℃, the PFOA components in the non-stick pan will decompose. However, generally speaking, when cooking, the temperature will not reach 26℃, but if frying food is cooked, the temperature of the pot may exceed 26℃. According to experts, the boiling point of water is 1℃. If you cook in a non-stick pan, the temperature will not exceed 1℃. In addition, if you just cook in a non-stick pan, pour the vegetables into the pan after the oil smokes, and the vegetables will be almost cooked when boiled with water, and the temperature will not be too high.

user's reminder: many dishes need to be fried when cooking, such as fried chicken wings and ribs, and the boiling point of oil is 32℃. When frying food, the oil is always boiling hot and the temperature is very high, 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.

Experts also warned that cooking in a non-stick pan should not use a shovel, which will accelerate the destruction of the non-stick coating and may release substances that are harmful to human body.

2. ceramic pot and casserole: It is not suitable for holding acidic food

Porcelain pots used to be recognized as non-toxic tableware, but there have been reports of poisoning in recent years. According to experts, some beautiful coats (glazes) of porcelain tableware contain lead. If the temperature is not enough when firing porcelain or the glaze ingredients are not up to standard, the pot may contain more lead.

When food comes into contact with the pot, lead may overflow the surface of the glaze and mix into the food. The national quality inspection department also found that the dissolution of lead and cadmium in some ceramic pot products exceeded the standard. The dissolution of lead and cadmium refers to the fact that long-term use of products with excessive dissolution of lead and cadmium in food, especially in acidic food, will cause heavy metal poisoning and seriously affect health. The national mandatory standards have strict restrictions on indicators that affect human health, such as the dissolution of lead and cadmium.

reminder: the enamel of the casserole contains a small amount of lead, so it is best to soak the newly bought casserole in 4% vinegar water and boil it first, so as to remove most harmful substances. The inner wall of the casserole is colored, so it is not suitable to store wine, vinegar, acidic drinks and food. Enamel tableware coated on the outer layer of enamel products is actually a layer of enamel, which contains substances such as aluminum silicate. If it is damaged, it will be transferred to food. When purchasing enamel tableware, the surface should be smooth and flat, the enamel should be uniform and the color should be bright.

3. stainless steel pot: It is not suitable to hold salt for a long time

The utensils made of stainless steel are beautiful and durable. But unqualified stainless steel pot will have potential safety hazards. Unqualified stainless steel pot, some of its compounds may be dissolved when used, and it will accumulate slowly in the body after being ingested many times. When it reaches a certain limit, it will be harmful to human health.

The unqualified stainless steel pot is generally unqualified for chromium exceeding the standard. Chromium is an essential trace element for human body, which plays a special role in sugar metabolism and lipid metabolism. Trivalent chromium is an element beneficial to human body, while hexavalent chromium is listed as one of the chemicals harmful to human body and one of the internationally recognized carcinogenic metals.

reminder: stainless steel is not completely rustless. If it is exposed to acids and alkalis for a long time, it will also react chemically, so that trace elements in it will be dissolved. Therefore, stainless steel tableware containers should not hold salt, soy sauce and vegetable soup for a long time; Should not be used to decoct traditional Chinese medicine. In addition, do not use strong alkaline or strong oxidizing chemicals such as soda, bleaching powder, sodium hypochlorite, etc. to wash stainless steel tableware containers, so as not to corrode the products.

4. aluminum pot: It is not suitable to stir-fry with a metal spatula

The characteristics of aluminum pot are excellent heat distribution, the heat transfer effect is 16 times that of stainless steel pot, and the pot body is lighter. However, improper use of aluminum will lead to a large amount of dissolution, and eating too much aluminum for a long time will accelerate human aging and be harmful to health. According to Dr. Huang Jian, deputy director of the Nutrition Department of the First Affiliated Hospital of Jinan University, aluminum pot is not suitable for high-temperature frying and cooking. High temperature or the collision and friction between a metal shovel and aluminum pot during cooking may release aluminum. In addition, aluminum pot can't contain strong acid and alkali dishes, such as pickled food, and it's better to use glassware.

Reminder: Some experts said that aluminum tableware should not be used as much as possible, because excessive aluminum accumulation in human body will cause mental retardation, memory loss and Alzheimer's disease. Aluminum tableware can not be used with iron tableware, and the chemical reaction between them will lead to more aluminum ions entering food. Matters needing attention in the selection of wok

1. The lid can be erected and operated conveniently

No matter the traditional cooking habits or the current cooking technology, the lid must be uncovered during the cooking process. If the lid can stand up, it will be easier to open the lid and save a lot of kitchen console space, while the ordinary lid will take up more space, especially for families with small kitchen positions, which is more crowded. Therefore, it is better to choose a pot with a vertical cover.

2. Handle

Speaking of its handle, it is suggested to choose a handle made of silica gel, which can prevent it from burning hands when in use. The handle of an inferior pot is easy to conduct heat, and it will burn our hands when held in our hands. Although it is impossible to conduct on-the-spot tests during selection, if we find that it is not scalding-proof after buying home, our hands will suffer. I burned my hand when I was cooking at home before, and of course it became red. I don't want this to happen to you again.

3. The joint between the handle and the pot body

The rivet at the joint between the handle and the pot body should be firm, and the pot will use 3 to 4 nails to fix it. This will increase its firmness, be more durable, and it is not easy to loose. When the wok is used for cooking, the stability of the wok body can also be guaranteed. It is suggested that you take the pot in your hand to check whether it shakes when you buy it, so as to avoid instability. Brand of wok
