The advent of "non -stick pot" brings great convenience to peoples lives. People do not have to burn the meat when they are not careful when they are cooked.This non -sticky pot has nothing to do with the appearance of the ordinary pot. It is just a layer of polytrafluoroethylene in the inner surface of the pot.It is made into this popular kitchen utensils.
Common types of non -stick pan
Teflon no sticky pot
Teflon is the transliteration of TEFLON.TEFLON is a registered trademark used on a series of fluorine polymer products.
In 1954, the wife of the French engineer Marc Gregoire, Colette, felt like a non -stick material TEFLON that the husband used to apply on the fishing line to prevent knotting on the fishing line.On the frying pan, the effect must be good.The "non -sticky pot" that saved countless modern housewives was born.
Ceramic coating does not stick to the pan
Ceramics played an important role in the upgrade of non -stick pots.Ceramic performance is stable and after thousands of years of use, it has fully proved its safety.Use nano -technology to make the surface of the product firming porosity to achieve the effect of non -sticky.
Precautions for non -stick pot
● Why not make acidic foods in non -stick pan
Professor Cong Sheng, deputy secretary -general of the non -metallic material professional committee of the Chinese Corrosion and Protection Society and Director of the Institute of Chemical Engineering, Shandong University, said: "Polytetrafluoroethylene has a congenital defect, that is, its combination strength is not high.The non -stick pan is not completely covered with polytetrafluoroethylene coating, and there are always some parts on the metal surface.The relevant standards of the ministry are formulated based on this principle. "The manager also believes that" coating is mainly used for anti -adhesion, but it is only sprayed with a thin layer, and the combination is not reliable."
● Which are acidic foods
"Acid foods include all kinds of meat, eggs, sugar, rice, etc." Professor Yu Kang, director of the Nutrition Department of Beijing Union Hospital, explained acidic foods. Whether foods are acidic or alkaline, are not distinguished by taste, but instead of taste, but instead of taste, but instead, theyThrough scientific methods, the types and quantities of the elements contained in food are detected to make judgments.Many foods for daily consumption are acidic foods.
● All non -stick pan cannot make acidic foods
Wang Fuhui, director of metal corrosion and protection of metal corrosion and protection of the Institute of Metal Research of the Chinese Academy of Sciences, said that it depends on the materials used in the pot body.
The non -stick pots sold in the market are mainly 3 kinds of materials:
Aluminum alloy with a thick layer of aluminum aluminum;
Stainless steel with a layer of chromium oxide on the surface, strong corrosion resistance, slow corrosion;
Iron and iron are easily corroded by a large area, which lifts the coating.Wang Fu will emphasize: "It is made of non -sticky pots such as corrosive metals such as iron and cannot be made of acidic foods. Using non -corrosion -resistant strong metal manufacturing non -stick pots, try not to make acidic foods as much as possible."
With nano ceramics as non -stick coating, no matter which metal is used in the pot body, it can achieve the effect of not easy to corrode, and you can safely make acidic foods.
