(Summary description)Due to the metal luster and corrosion resistance of stainless steel tableware, it is gradually being made into tableware for use. Stainless steel is made of iron-chromium-nickel alloy and mixed with trace elements such as molybdenum, titanium, cobalt, manganese and cadmium. These several elements are essential trace elements for the human body, and proper intake is beneficial to human health. However, improper use of stainless steel tableware is still harmful to health, so what matters should be paid attention to in the use of stainless steel tableware?

1. Before use, apply a thin layer of vegetable oil on the surface of the utensil and then dry it on the fire, which is equivalent to wearing a yellowish oil film "clothing" on the surface of the utensil. In this way, it is easy to clean in use and can extend the service life.

2. Do not store salt, soy sauce, vinegar, vegetable soup, etc. for a long time, because these foods contain a lot of electrolytes. If they are stored for a long time, stainless steel will also react electrochemically with these electrolytes like other metals, making them toxic. The metal elements are dissolved out.

3. Do not use stainless steel pots to boil traditional Chinese medicine, because traditional Chinese medicine contains a variety of alkaloids, organic acids and other ingredients, especially under heating conditions, it is difficult to avoid chemical reactions with them, which will make the medicine ineffective, and even produce certain toxicity. Large complexes.

4. Do not use strong alkaline or strong oxidizing chemicals such as baking soda, bleaching powder, sodium hypochlorite, etc. for washing. Because these substances are strong electrolytes, they also react electrochemically with stainless steel. Keep cooking utensils clean and scrub them frequently, especially after storing vinegar, soy sauce and other condiments, and keep cooking utensils dry.

Fourth, elaborate on the composition and impact of stainless steel. Stainless steel tableware generally contains chromium and nickel. Chromium is a material that prevents the product from rusting, while nickel is a corrosion-resistant material. If you use low-quality stainless steel cutlery or use stainless steel cutlery in an inappropriate way, it may cause heavy metals to harm human health. When buying, you should pay attention to the parameters indicated above.

Stainless steel pots are easily stained with black dirt that is difficult to scrub. The decontamination method is to add about half a pot of clean water to a larger pot and put some pineapple peels in, then put the small pots in one by one, heat and boil on the stove for a period of time, wait until it cools and take it out, you will find these The pot is as bright as new. However, it should be noted that if it is stainless steel tableware with wooden handles, it should not be steamed, boiled or scalded in boiling water to avoid expansion and damage of wooden handles and plastic handles due to heat.

After using the stainless steel for a period of time, coffee-colored rust will appear in the pot. It is not rust, but the substance formed on the wall of the pot by the condensation of minerals in the water for a long time. These marks do not need to be removed, and they are not harmful to the human body. If you must clean it up, try pouring a little white vinegar into the pot and shaking it well, then boil it over a low heat for a while to see the effect.

However, after cooking the white vinegar, you must use a detergent such as detergent to clean it, otherwise it will leave a sour taste. You can also use fine water scrubbing paper to grind away those traces evenly.
