If the storage method is appropriate, the shelf life of salt is 5 years, and it needs to be stored in a closed, dark, cool and ventilated place.

If left in a dry and ventilated place, it will not deteriorate for eternity.

The salt will be damp, and then some of the ingredients have air joints, which are best placed in a cool place.

Salt does not deteriorate, it does not breed bacteria, unless it is damp, but it is also used after drying, so most salt has no expiration date;

But there are a few that have a shelf life, and the shelf life of iodized salt refers to the period during which iodine volatilizes, so it will not deteriorate after expiration.

MSG expires because it is chemically synthetic.

Table salt does not expire. Shouhu.

Reason: The main component of table salt is sodium chloride, which is chemically very stable. Like table sugar, table salt is often used to preserve food and is a natural preservative.

However, if the iodized salt we often eat, if it is not protected from light and high temperature, the iodine content will be reduced if it is left for too long, the salt will be agglomerate, and the salt quality will not change and will not affect the consumption. Therefore, the state does not stipulate the shelf life of ordinary edible salt.

The purchased iodized salt should be properly stored:

1) The container for iodized salt should be a brown shading bottle or ceramic jar with a lid.

2) The iodized salt should be placed in a cool, dry place, away from direct sunlight and moisture absorption, and stored away from the stove to avoid the influence of high temperature grip.

3) The storage time of iodized salt should not be too long, and it should be bought as you use it and stored appropriately.

Salt generally expires.

The main chemical component of salt is sodium chloride, which is chemically very stable, but it does not mean that it has not deteriorated. If it is stored for a long time, it may be contaminated by radioactivity after being wet, which will affect the taste. It is necessary to develop good living habits, avoid eating some spoiled food, and achieve balanced and comprehensive nutrition.

How to preserve table salt:

1. Sealed preservation, salt is not properly preserved, it is easy to get damp, you can pour the salt into a small jar for preservation, take it with you, it is very convenient, and it can also ensure that the salt does not deteriorate. In addition, iodine-containing table salt is easily oxidized and decomposed, so it should be stored in a cool and dry place, otherwise the salt will lack nutritional value.

2. Because iodized salt will have more nutrients, special attention should be paid when preserving. Iodine-containing table salt is easily oxidized and decomposed, so it should be stored in a cool and dry place, otherwise the salt will lack nutritional value. Table salt, which can contain iodine, is sealed in a colored jar to protect it from light and moisture absorption.

3. If there is more salt, you can put an appropriate amount of corn starch and rice into the salt, which can maintain the dryness of the salt, and it can be stored for a long time in this way, and it is more convenient to operate.
