Jinhua city in zhejiang province a reader calls: because of stainless steel utensils metal performance is good, beautiful and durable, and not easy to rust, so her family of stainless steel kitchen utensils. Recently because of her grandson was ill, the doctor with some Chinese medicine. So she used stainless steel utensils, decoct Chinese traditional medicine, which know is daughter-in-law see don't let the children take the traditional Chinese medicine, said with a stainless steel household utensils decoct Chinese traditional medicine, can release some poisonous substances, decoct Chinese traditional medicine cannot drink like this, she asked how so?
According to reporter understanding, recently it is reported that stainless steel household utensils should not be boiled decoct Chinese traditional medicine. But the ministry of health, the state administration of traditional Chinese medicine of traditional Chinese medicine of medical institution "tisanes room management rules, the operation method of traditional Chinese medicine medical institutions tisanes, tisanes vessels made detailed provisions: tisanes containers shall be based on materials such as ceramic, stainless steel utensils advisable, disable iron vessels such as easy to corrosion. Decoct Chinese traditional medicine also cannot use aluminum vessel, otherwise will react by harmful substances.
Concerned expert thinks, tisanes instruments had better use an earthenware pot, sand tank, such as ceramics, chemical properties of the ceramic ware is stable, not easy to react with pharmaceutical ingredients, and uniform heat conduction, heat preservation performance is good.
Reports said housewife should be paid attention to, don't use stainless steel vessels contains salt, soy sauce, served soup for a long time, also don't acidic fruit juices. Because these foods in the electrolyte can complex with the metal elements in the tableware "electrochemical reaction", make the element excessive dissolved explanation.
At the same time, stainless steel tableware washing is unfavorable use alkaline, soda, bleaching powder, etc. Because of the strong electrolyte can also react with certain ingredients in tableware, stainless steel tableware and erosion, the dissolution of harmful elements. Stainless steel tableware should also be careful not to match with aluminium utensils to use, because the two different hardness, share when the latter are more likely to be damaged; There are aluminum and iron are two different metal chemical activity, when one of them to food ingredients (such as salt, acid, etc.) as electrolyte, aluminum and iron can form a chemical batteries, make more aluminum ions into the food. "Aluminum poisoning" characterized by mental decline, memory loss and dementia, etc. Stainless steel tableware is unfavorable use big fire to cook food, because the stainless steel small coefficient of thermal conductivity, heat dissipation at the bottom of the slow, such as fire too, can make the burned in the bottom, agglomerate.
