Will stainless steel kitchenware affect human health?

Stainless steel woks are different from other metal pans. Most of them tend to turn black when heated by a high fire. To avoid this reaction, the surface treatment of the new kitchen utensils is very important. Just apply a small amount of fat, such as peanut oil or animal oil, on the surface of the tableware before use. When cooking the food, heat it on a slow fire for a period of time, and wait for the surface of the tableware to attach a layer. After the oily anti-oxidation film, use it normally according to your needs. In addition, improper operation of stainless steel kitchen utensils may cause harm during normal use. Pay attention to the following 2 points:

1. Stainless steel kitchen utensils should not be used for long-term storage of salt, soy sauce, and hot soup. These foods contain electrolytes, and chemical reactions will occur after prolonged contact, and harmful metal elements will be precipitated. Long-term use will cause chromium poisoning and cause serious harm to human liver function.

2. Stainless steel kitchen utensils can not be used to torment Chinese medicine. Chinese medicine contains alkaloids and organic acids, which will cause chemical reactions under heating conditions, losing efficacy and even poisoning.

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 a high-quality stainless steel pot is very strong and stable, and has good corrosion resistance. It will neither fall off nor dissolve under normal use, so no chromium will dissolve out and migrate into the food to cause poisoning.
