Extended data
Pay attention to the following points when using and storing edible salt:
1, sealed and saved.
Iodized salt is easily oxidized and decomposed under the influence of heat, light and wind, so it should be stored in a color sealed container with a cover. Store in a dry and cool place to avoid exposure to sunlight and moisture absorption in the air. Eat while buying, don't buy too much at a time and store it for a long time.
2. Avoid high-temperature stir-frying.
Iodized salt will decompose into elemental iodine and volatilize at high temperature, so don't use salt to "explode the pot" when cooking. Adding salt when cooking can reduce the loss of iodine.
Common edible salt in the market has no shelf life, but edible salt containing trace elements such as iodine or zinc has a shelf life of one year.
