The correct use of the regular manufacturers of qualified products will not cause harm to humans

" Stainless steel tableware can not be cooking, storing excess acid, alkaline food, not containing acidic fruit juices, because these foods in the electrolyte with tableware metal element complex electrochemical reaction, make the trace metal elements in excess of dissolution and precipitation, including a few harmful heavy metal elements. Human intake of these elements, accumulation. In the course of time to reach a certain concentration, can cause poisoning. " Chengdu media reporter Miss Li recently from the Internet to see this news be startled at, she worried about their daily use of stainless steel tableware can be caused to his body harm.

For Miss Li this concern, the reporter interviewed Sichuan Normal University School of chemical engineering and materials science professor Long Bingqing. Long Bingqing said, as long as the correct use of the regular manufacturers of qualified stainless steel tableware, will not cause a harm to human body.

Stainless steel tableware security assurance

The reporter understands, national tableware industry association as early as 1994 was made of stainless steel tableware industry standards of stainless steel tableware, technical requirements, test method, inspection rules and signs, packaging, transport and storage for.

Right use of will do no harm

Stainless steel tableware generally containing chromium and nickel, chromium is the product does not rust materials, and nickel is corrosion resistant material. If the use of inferior stainless steel utensils, or the wrong way to use stainless steel tableware, it is possible to cause heavy damage to human body health. In order to prevent the nickel, chromium and other heavy metals harmful to human, the soluble analytical volume are related to the standard. Therefore, as long as the regular manufacturers of stainless steel utensils can be assured use. In addition, in the absence of strong oxidizing or strong acid and strong alkali condition, heavy metal solution analytic volume is in a safe range, even with a small amount of heavy metal leaching, the body will slowly through the new supersedes the old. Its outside eduction body, there is no harm to the body caused by accumulated problems.

Stainless steel tableware in addition to iron, chromium, nickel alloy main component, also containing manganese, titanium, cobalt and molybdenum and other trace elements, which are indispensable to the human body, the body can not be synthesized, must from external intake. Research shows that, with stainless steel tableware cooking food, it contains the Fe-Cr-Ni capacity than the other pot cooking is high, also contains trace elements such as manganese molybdenum cobalt, and ordinary food of these trace elements content is minimal. If human body lacks one or several kinds of trace elements, it will suffer from a variety of diseases. If long-term lack of dietary chromium nickel manganese cobalt, molybdenum and other trace elements, will increase the risk of diabetes and cardiovascular disease ( such as coronary heart disease, stroke and etc.).

The tips

The correct use of stainless steel tableware

In 1, not long time containing salt, soy sauce, soup and so on, because these foods contain a lot of electrolyte, if a long time, will be the same as other metals like stainless steel, and the electrolyte on electrochemical reaction, the toxic metal elements are dissolved out.

2, can not use stainless steel utensils for decocting Chinese medicine, Chinese medicine contains many alkaloids, organic acid and other ingredients, especially under the condition of heating, it is difficult to avoid the chemical reaction with, and make the drug failure, even generate some more toxic compounds.

3, do not use strong alkaline or strong oxidizing chemicals such as soda, sodium hypochlorite bleaching powder, washing. Since these substances are electrolyte, will also react with stainless steel.
