The shelf life of edible salt is related to its processing methods and storage conditions. Generally speaking, the shelf life of refined salt is relatively long, which can reach about five years. The shelf life of raw salt is short, only about two years. In addition, edible salt should be moisture-proof, moisture-proof, sun-proof and insect-proof when stored.

Matters needing attention in the preservation of edible salt

1. Avoid direct sunlight: edible salt should be stored in a cool and dry place to avoid direct sunlight. Because ultraviolet rays in the sun will volatilize iodine in edible salt, which will lead to the deterioration of edible salt.

2. Sealed storage: Edible salt should be stored in a sealed container to avoid contact with air. Because the moisture in the air will damp the edible salt, which will lead to caking or deterioration.

3. Avoid getting wet: Edible salt should be stored in a dry place to avoid getting wet. If the edible salt gets wet, it will cause problems such as caking and deterioration.

4, a small amount of purchase: the shelf life of edible salt is generally three years, but too long storage time will also affect its taste and use effect. Therefore, it is recommended to buy an appropriate amount of edible salt every time to avoid long storage time.
