Department store Exhibition: A variety of metal POTS and pans, how do you choose?

  

With the development of modern industry and the progress of human science and technology, all kinds of metal matrix POTS emerge in an endless stream, and the metal POTS sold on the market are mainly divided into the following categories: aluminum POTS, copper POTS, iron POTS, stainless steel POTS, non-stick POTS and titanium alloy POTS。Due to the different metal materials, these types of POTS have advantages and disadvantages in actual use。The following department store exhibition Xiaobian to you said。

铝锅

  

  The aluminum pot is light, fast and uniform in heat transfer, because the metal surface is covered with a layer of aluminum oxide, which can protect the pot body from rust。Experiments show that under the action of strong alkali, the protective layer of alumina will not be destroyed in a short time, so the aluminum pot is more durable。

  

  In daily use, many people like to brush the pot with steel balls to wipe the aluminum pot to shine, so that although the oil on the pot is wiped, but also destroyed the protective oxidation film, in the temperature is too high or cooking acidic or alkaline food, the aluminum in the pot body will migrate to the food, and then accumulate in the human body。Long-term intake of excessive aluminum can damage the brain, cause Alzheimer's disease, may also lead to osteoporosis, anemia and other diseases, pregnant women accumulated excessive aluminum will affect fetal development。

  

  铜锅

  

  The department store learned that copper is one of the earliest metals discovered by humans, and it is also the metal that humans began to use earlier。Natural copper has been used in China since the Xia Dynasty 4000 years ago, and copper POTS are a kind of traditional cooking POTS。

  

  However, in a humid environment, the copper pot is easy to produce patina, so it needs to be dried and stored, and it is not suitable for long-term storage of food。When cooking food in copper POTS, a small amount of copper will dissolve out, and long-term excessive intake of copper by the human body will lead to Wilson's disease and chronic interstitial disease。In GB 4806.In 9-2016, it was also made clear that copper and copper alloys should not be in contact with acidic foods, and consumers should pay attention to them during use。

  

  铁锅

  

  Iron pot is China's traditional pot, although it looks a little bulky, but it is solid, durable, good thermal conductivity is beyond doubt。Studies have shown that the iron content of food cooked in iron POTS is nearly five times higher than that of food cooked in other types of POTS. Using iron POTS can prevent iron deficiency anemia in the human body. In addition, iron POTS can make food absorb salt more efficiently。

  

  The disadvantage of the iron pot is that it is easy to rust, so it needs to be dried and stored。Consumers should be forbidden to cook mung beans with an iron pot, because the tannin in mung bean skin can interact with iron to produce tannin iron, and make mung bean soup black, affecting the taste of mung bean soup, while not conducive to human digestion and absorption。Mung beans should be cooked in a casserole or aluminum pot。

  

  Stainless steel pot

  

  Stainless steel pot is a metal alloy pot made of iron, nickel, chromium and other trace elements。Chromium can form a strong oxide film on the surface of the stainless steel pan, isolating the metal from the outside world without chemical reactions。The addition of nickel will also make the pot have good chemical stability in water and air, and good acid and alkali corrosion resistance。

  

  However, in the strong alkaline or strong oxidizing reagents, such as bleach powder, soda, sodium hypochlorite, etc. have a strong corrosion effect on the stainless steel pot, so do not use these chemical agents to wash the stainless steel pot。In addition, the stainless steel pot should not be fried, because the alkaloids and organic acids in the Chinese medicine will react chemically with the chromium in the pot under heating conditions, generating more toxic chromium compounds, and also making the Chinese medicine lose its efficacy。

  

  Non-stick pan

  

  Non-stick pans are made by covering the inner surface of metal pans with a Teflon coating。Teflon coating is based on polytetrafluoroethylene, and its lower surface can make it difficult for other substances to adhere to its surface, so the non-stick pan can avoid the phenomenon of conventional metal kitchen utensils sticking to the pan when used, which has become a lot of and popular metal kitchen utensils on the market。It is resistant to low and high temperatures, with a range of -200 to 250 degrees Celsius, corrosion resistance, and does not absorb water。

  

  However, when using a non-stick pan, care should be taken to avoid sharp spatula or metal utensils to destroy the non-stick pan coating, and heat-resistant nylon or wooden spatula should be used。Due to the uniform heat transfer of non-stick pan, only small to medium fire can be used to avoid high temperature cooking methods above 250 degrees Celsius。After use, it should be cleaned with cold water after the temperature drops slightly, and do not vigorously scrub the pan surface with a metal ball or sponge。

  

  Titanium alloy pot

  

  The department store learned that the titanium alloy pot is a metal pot forged with titanium alloy。With the maturity of metal smelting technology, titanium, which ranks tenth in the distribution of elements in the Earth's crust, is not only used to manufacture aerospace devices and sports equipment, but also gradually used to make titanium alloy POTS。Titanium alloy pot has many advantages compared with the traditional pot, it is corrosion resistant, high strength, light weight, easy to wash and will not cause damage to the kitchen, no odor residue。

  

  Due to the high price, the proportion of consumers using titanium alloy POTS on the market is small。It is believed that with the development of the economy and the improvement of the production process, titanium alloy pot will be favored by more and more consumers and become the main force of the metal pot market。

  

  When purchasing metal POTS, consumers should pay attention to whether the pot information marked on the product label is clear and clear, check whether the surface material of the pot body is uniform and smooth, and whether there is sand hole or cracking。All kinds of metal POTS have their own advantages and disadvantages in cooking, consumers can choose the right pot according to the actual needs of cooking, at the same time, in use and use after the maintenance of metal POTS。

  

  The above is the introduction of the small series of POTS and pans in the department store exhibition. I hope that through this article, we can have a further understanding and understanding of it。
