However, most of the edible salt will not be marked with a specific shelf life, and the product itself can be preserved for a long time. As long as there is no deterioration during use, it will generally not delay normal use. They have many additives, which are easy to be oxidized and cause nutrient loss after a long time, so salt has a shelf life, so it has a shelf life.
Salt has the privilege stipulated by the state, which can be exempted from the shelf life, but it does not mean that it has expired. It is suggested that the salt in salt containers without shelf life should be eaten within 1 year. Iodized salt is easily oxidized and decomposed under the influence of heat, light and wind. The main component of edible salt is sodium chloride, which is quite stable and will not volatilize with time warp. It is also the main source of salty taste.
Recommendation of preservation method of edible salt

2. Avoid direct sunlight. Sunlight will make salt wet and sticky, so avoid direct sunlight. It is a good choice to store edible salt in a dark place or use an opaque container.
3. Use desiccant Put some desiccant in the salt box or container to absorb the moisture in the air and keep the salt dry. Simple materials, such as silica gel, dried straw or rice, can also achieve the same effect.
