The advantages and disadvantages of non -stick pan

The advantages and disadvantages of non -stick pan
The advantages and disadvantages of non -stick pan are generally paid more attention to our daily home supplies and home equipment. Many options, let’s take a look at the advantages and disadvantages of non -stick pots.
The advantages and disadvantages of non -stick pan 1 advantage:
1. Easy to clean
The non -stick pan overcome all the shortcomings of the traditional pot, easy to clean, gently wipe it clean. It can be easily fried, stir -fried food without sticking to the bottom. It can minimize oil use, and the kitchen is clean and less oil smoke.
2. The amount of food made is small
. It can also help reduce the intake of fat and conform to the modern people’s pursuit of low -fat and low -calorie consumption trends. The most important thing is that it has no harm to the human body.
Disadvantages:
1. Do not make acidic foods
The iron can easily corrode in large acid area, thereby lifting the coating. It is made of non -sticky pots made of iron such as iron, and acidic food cannot be made. Use non -sticky pots made of corrosion -resistant metal, and try not to make acidic foods as much as possible.

. The main component of the non -sticky pan may be generated by the toxic gases. After the temperature is above 380 degrees, some toxic gases began to produce, such as fluorida, CO2, etc.
Os how to maintain it without sticky cooker
1. Apply it with edible oil
When used for the first time, there is a layer of protective film on the non -stick pan. The thin layer of edible oil is used to maintain the coating of the surface of the cooker. After the oil is immersed, it is cleaned to use it.
2. The sharp utensils cannot be used
The material in the non -stick pan is special, and it is very vulnerable to damage. Frequent use of hard shovel will cause domestic coating Extend the service life of non -stick pots and maintain well.
. After cooling, clean the boiler on the boiler, add oil or food to fire for cooking; after use, the pot should be placed on the pot frame, and the temperature should be slightly dropped, then washed with water. Wash the hot pot directly in cold water.
4. Do not overly clean
The use of non -stick pan is extremely convenient, and the cleaning method is simpler. Do not use cleaning items such as detergent or wire balls such as detergent or wire balls when cleaning the non -stick pan. A small amount of detergent can achieve the cleaning effect with cleaning cloth.
The advantages and disadvantages of non -stick pan 2 non -sticky pot carcinogenic? CCTV came to rumor
Although it prevails for a period of time, it is not dared to use due to being exposed and carcinogenic. The CCTV “Life Circle” column has responded to this issue and invited experts to perform experiments. Let’s take a look at what is going on. After investigation, the reporter found that there are many types of non -stick pots on the market today, with quality non -stick pots, aluminum non -stick pots, stainless steel non -stick pots, alloy steel non -stick pots, etc. The expensive ones are thousands of pieces. The people interviewed said: The reason why they chose to use non -stick pan is because they do not stick to the bottom of the pan when cooking, and they can maintain the original flavor of the ingredients, and it is easier to clean.
It the use of non -stick pots can also be used. The key is to buy non -stick pots with quality assurance. After quality sampling, some non -stick pots do not meet national standard QB -T2421. Among the sampling. The product is mainly concentrated in the thickness of the non -stick layer and chemical indicators. Experts said that the coating of non -stick pan is called Teflon, which is mainly polytetrafluoroethylene material, which is a chemical inert material. Due to the good lubrication and low friction coefficients, this coating is often used on kitchenware such as non -stick pan. Eating a small amount of non -sticky pan can be excreted by the human body, which is harmless to health.
Is when buying non -stick pots, don’t be greedy for cheap, buy some inferior products. Because if it encounters high temperature, the polytefluoroethylene contained in this non -sticky coating will decompose fluoride, which has a strong stimulation effect on the lungs, which will lead to emphysema. Generally, the variability temperature of non -stick coating is 260 degrees Celsius, and the decomposition temperature is 350 degrees Celsius. When the temperature reaches 350 degrees Celsius, fluoride will be decomposed.
In fact, it is wise to choose an iron pot. Although it may be more troublesome, it is healthy. When cooking, just pay attention not to boil or stick, generally does not reach the decomposition temperature, and it is sufficient to cook normally. Therefore, we draw conclusions that the non -stick coating itself will not cause cancer. Only when the temperature reaches 350 degrees Celsius, the coating will decompose harmful substances, accompanied by food intake, affecting physical health.

The use of non -stick pan, have you paid attention to these details?
1. Pay attention to maintenance. When using a non -stick pan for the first time, tore the product label on the top, then rinse it, and apply a layer of edible oil maintenance. The non -stick pot is well maintained, and the chance of volatile toxic substances will be relatively reduced.
2. Do not burn and non -stick pan. As mentioned earlier, when it reaches a certain temperature, non -stick coating will decompose substances that have stimulating effects on the lungs and damage lung health. Before cooking, pour an appropriate amount of edible oil in the non -stick pot to prevent the coating from falling off due to high temperature. When cooking on high heat, there must be food or water in the pot.
3. Cold after cooling. After cooking, do not clean the pot immediately. Many people are used to washing the pot after cooking. This is wrong. After the temperature of the non -stick pan is reduced, it is cleaned. After cooking, the pot is still in a high temperature. If it encounters cold water, it is easy to separate the body and coating due to thermal expansion and contraction.
4. The tool should be selected. When using non -stick pan to stir -fry, you should choose heat -resistant nylon, plastic or wooden spatula to prevent damage to the surface of non -stick pan and increase the risk of harmful substances. In addition, do not choose too hard cleaning tools such as wire balls when cleaning or sticky pots, otherwise it will damage the coating.
5. Pay attention to the storage method. When not in use, dry it and store it to avoid stains from remained in the pan to prolong the life of the non -stick pan and prevent additional damage.
Igly when choosing a pot, first iron pot, because from the perspective of cooking, although the iron pot is sticky when cooking, the cooking is better and the insulation and sealing properties are more good. And when using an iron pot, it is not easy to cause chemical reactions, so it is more beneficial to personal health. Of course, the housewife who is accustomed to the use of non -stick pots can also be used appropriately.

If Note
Why can’t you make acidic food for non -stick pan?
Mou Fluoride Expert, the Deputy Secretary -General of the Non -Metal Materials Professional Committee of the Chinese Corrosion and Protection Society, and Director of the Institute of Chemical Engineering of Shandong University, Professor Cong Sheng said: “Polytetrafluoroethylene has a congenital defect, which is its combination The strength is not high, and the non -sticky pot is not completely covered with polytetrafluoroethylene coating. There are always some parts of the metal surface exposed.
The acidic substances are prone to corrode the metal body. Once the body is corroded , Resulting in a large area of ​​coating off. The relevant standards of the Ministry of Health are formulated based on this principle. “Professor Administration also believes that” coating is mainly used for anti -sticking, but it is sprayed with a thin layer, and the combination is not reliable. It is definitely not possible to stir -fry with iron shovel. “
Which are acidic foods?
“Acid foods include all kinds of meat, eggs, sugar, rice, etc.” Professor Yu Kang, director of the Nutrition Department of Peking Union Hospital, explained the acidic food. Instead, it is judged through scientific methods to detect the types and quantities of the elements contained in food. Many foods eaten daily are acidic foods.
The non -stick pan can not make acidic foods?
Wang Fuhui, director of metal corrosion and protection of the Institute of Metal Corrosion and Protection of the Institute of Metals of the Institute of Chinese Academy of Sciences, said that it depends on the materials used in the pot body.
The non -stick pots sold on the market are mainly 3 materials:
aluminum alloy, a thick layer of aluminum aluminum;
stainless steel, a layer of chromium oxide on the surface, corrosion resistance is compared Strong, slow corrosion;
Iron, iron can easily be corroded by large acid area, which lifts the coating. Wang Fu will emphasize: “The non -sticky pot made of corrosive metals such as iron cannot be made of acidic foods. Use non -sticking pots made of corrosive metals and try not to make acidic foods.”
Coating, no matter what kind of metal use of the pot body, it can achieve the effect of not easy to corrode, and you can safely make acidic foods.
