my country’s quality inspection department has repeatedly stated that chromium is irritating and corrosive to the skin, mucous membranes, and digestive tract, and easily enters human cells. Inhalation of higher levels of chromium can cause damage to internal organs such as liver and kidney, accumulate in the human body and cause cancer, and may also induce genetic mutations.
Since chromium may be harmful to health, why not require stainless steel kitchenware to contain chromium? The answer is no.
The reason why stainless steel does not rust and has good corrosion resistance is because the surface of stainless steel can naturally form a stable, dense and strong passivation film, and chromium is an essential component for forming a passivation film on the surface of stainless steel. The passivation film of high-quality stainless steel kitchenware is very strong and stable, and has good corrosion resistance. It will neither fall off nor dissolve under normal use, so there will be no chromium dissolved and migrated into the food to cause poisoning.
Qualified stainless steel products must not only contain chromium, but also must contain enough chromium. The chromium content of stainless steel products usually must reach more than 13% to avoid rust and corrosion. The reason why low-quality stainless steel kitchenware is prone to rust is precisely because its chromium content does not meet the standard, which affects the corrosion resistance. Chromium, which is supposed to play a protective role, will migrate to food and become a health hazard. Therefore, to avoid chromium poisoning caused by stainless steel kitchenware, the quality of the stainless steel kitchenware itself must first be guaranteed. Secondly, if you encounter stainless steel kitchenware that is prone to rust, it is better to use less.
Remind you that stainless steel kitchenware should avoid prolonged exposure to acids and alkalis; do not use stainless steel kitchenware to torment Chinese medicine, to prevent stainless steel from reacting with alkaloids and organic acids in Chinese medicine under heating, causing chromium to dissolve; stainless steel kitchenware is deformed or the surface layer When worn or roughened, it should be replaced in time.
