Generally, the shelf life of salt is about three years.

according to national regulations, the shelf life of salt is three years. In fact, salt has no shelf life. As long as it is stored properly and does not make salt wet, it can be eaten normally. If it is unopened edible salt, it can still be eaten after three years, but if it is unopened edible salt, it is best not to eat it after three years, because some other trace elements will be added to the salt now, which will affect the shelf life of the salt.

With proper storage methods, salt can keep good quality and availability for a long time. Even if there is no definite shelf life limit, it is recommended to check the appearance and texture of salt regularly. If any abnormality (such as caking, odor, etc.) is found, it is recommended to replace it with new salt.

Precautions for salt preservation

1. Moisture-proof and dryness: Salt is easy to absorb moisture and agglomerate, so it should be kept in a dry and well-ventilated place, away from water sources or humid environment, and it is best to choose a well-sealed container or package.

2. Avoid pollution: Make sure to take out the salt with a clean spoon or hand before use, and avoid using wet or impure tools to avoid polluting the salt.

3. Avoid high temperature: salt should be avoided from being exposed to too high temperature, because high temperature may lead to salt caking or quality degradation. Therefore, salt can be stored at room temperature.
