Buy a non-stick pan with or without coating. If you want a real non-stick pan, you should buy a coated pan, but the service life will generally not exceed 3 years. If you don't want a coating, but want it to be as non-stick as possible, an uncoated "non-stick pan" is still good. Take good care of it and sprinkle water for ten years.
A real non-stick pan must be coated. In the frying process of a general pot, the ingredients will react chemically with the surface of the pot because of heating and will stick to the pot.
The reason why the iron pan does not stick to the pan is that after a long time of use, an oxide layer has formed on the surface of the iron pan, which can isolate this chemical reaction. Therefore, what the coating needs to do is to separate the ingredients from the pan surface to achieve a truly non-stick effect, which is generally smokeless.
The uncoated non-stick pan is basically made by physically changing the shape of the pan surface to form a concave-convex shape. At the same time, the pan surface is also oxidized, which reduces the contact area between the ingredients and the pan surface, making the cooking effect (infinitely) close to non-sticky, but it will still stick in the early stage and needs to be raised like an ordinary iron pot. This kind of pot will be made of copper and iron, which has good thermal conductivity, can't control the oil temperature, and will definitely produce lampblack, and it is best not to make acidic food, which will corrode easily over time.
How to choose the organic easy-to-drip coating for non-stick pan This is also the most original coating material-PTFE, the main component of which is PTFE, which is a relatively stable chemical substance. It is safe and non-toxic, even if it is eaten. However, it should be noted that when the temperature of Teflon exceeds 260 degrees, it will produce harmful substances, so the material of the pot itself will be made of alloy to avoid the temperature exceeding 260 degrees, which is also the oil smoke point. Below this temperature, there will be no oil smoke. You'd better not use it when the coating of your pot falls off and begins to smoke.
Advantages: cheap, basically 200 ~ 600 is enough, and of course there are lower ones. Suitable for people who don't usually cook, but want to prepare a pot at home.
Disadvantages: The coating is useless. If you use it frequently, 1 will die in two years at most. And you should be very careful when you use it. Wooden shovels and silicone shovels can only be wiped with rags when washing. If it really won't wash off, just soak it in water for a while and never use steel balls.
Inorganic solid coatings include coatings made of ceramics, titanium gold, medical stone, rocks and other minerals. It is natural, safe and harmless. Even if the surface falls off, eating it in the stomach is also a mineral supplement. Moreover, this material is particularly strong, and it will be basically no problem in 3 or 4 years. It is usually recommended to use a wooden shovel, and it is okay to use a shovel occasionally.
Ceramic coating, its main component is timely, safe and non-toxic, and this material can withstand high temperatures above 500 degrees. Although there will be a little oil smoke, the frying effect is still optimistic. But use it carefully and don't knock.
Medical stone and rock coating, both of which are actually mineral layers-silicate, similar to ceramics, but although their durability and non-stick are far superior to Teflon and equivalent to ceramic coating, their durability is slightly weaker than ceramic coating, and they can generally be used for more than two years.
Titanium coating is used in aircraft, artillery, spacecraft and other fields. Titanium material is very commonly used, and it will also be used for human bone marrow implantation, food processing parts and so on. , so the safety is naturally unknown. And its wear resistance, heat resistance and corrosion resistance will be much better than the first two.
Diamond coating, made of real diamonds, is absolutely excellent in wear resistance and corrosion resistance ~ but compared with titanium coating, its strength is still a little lacking.
The brand of non-stick pan recommends Supor little red dot non-stick pan, which is the third generation. Titanium coating, durable, smokeless and non-sticky. What I like is the red dot design. When the red dot becomes solid, it's time to stir-fry the vegetables. This kind of pot has both induction cooker and gas stove, as well as special gas stove. Special gas stoves are cheaper. Generally, you don't need an induction cooker for cooking, just buy a special gas stove.
STONELINE ore non-stick pan German brand, the surface is made of alpine ore, which is durable through five-layer composite casting. But there is a small drawback, it can't be smokeless, and there will be a small amount of oil smoke. This is also the characteristic of this coated pot.
Woll diamond wok is a German brand, and it is really a real wok. Especially durable. After more than 30,000 rubs, it is still as bright as new. Because the bottom is thicker, heating is slower, but it is absolutely close to smoke-free, and it still has the advantage of being expensive.
