The stainless steel material in the stainless steel lunch box is made of iron, chromium, nickel alloy, and then mixed with trace elements such as molybdenum, titanium, cobalt and manganese. The metal performance is good, and the made utensils are beautiful and durable. However, if stainless steel kitchenware is used improperly, heavy metal elements will slowly “accumulate” in the human body, endangering health.
When using stainless steel tableware, pay attention to the following taboos: Avoid storing foods that are too acidic or too alkaline. Stainless steel tableware is not suitable for holding salt, soy sauce, vegetable soup, etc., and also not suitable for holding acidic juice. Because the electrolyte in these foods can have a complex “electrochemical reaction” with the metal elements in the tableware, causing excessive dissolution of the elements. It is worth noting that Chinese herbal medicines should not be used, which have complex ingredients, and most of them contain a variety of alkaloids and organic acids. When heated, it is easy to chemically react with certain components in stainless steel, which reduces the efficacy of the medicine, and may even generate some more toxic substances.
