Up knowledge! How to store salt in bulk? Does the stored salt need to be sealed

Because salt is an indispensable item for every household, many people often buy a lot of salt at one time. So how to save so much salt? Do you need to seal it? Let's learn some basic preservation principles of salt:

1. Keep the salt sealed.

Salt is easily soluble in water and has strong hygroscopicity. It is very easy to crystallize when exposed to air for a long time. Moreover, people now eat salt with iodine, and iodine is very volatile and easy to oxidize and decompose, so it is easy to lose its original nutritional value.

2. Store in colored containers.

The edible salt bought in people's daily life is iodized salt with higher nutritional composition, but attention should be paid to preservation. Because iodide is extremely unstable, easy to decompose, volatilize and fail, and easy to be affected by light, high temperature and humidity, it is easy to undergo oxidative decomposition. Therefore, iodized salt needs to be sealed and stored in colored containers.

At the same time, the colored container can effectively prevent light, avoid heat absorption and moisture absorption of salt, and keep salt for a longer time. The container should also be placed in a ventilated and dry place to avoid exposure to the sun and humidity, so that it can be stored for a longer time.

3. Add starch or rice to salt to preserve.

Adding some corn starch or a handful of rice to the salt can keep the salt dry without moisture, and the salt can be preserved for a long time.

4. Salt is heated at high temperature.

Stir fry the salt in the pot, which can convert the magnesium chloride in the salt into magnesium oxide. Therefore, the salt will not agglomerate or get wet, which is very practical and convenient.

5. The correct way to store salt in the refrigerator.

When the salt taken out from the refrigerator is placed at room temperature, dew will be generated on the inner side of the salt container or package, so that the salt is easy to solidify. Therefore, if salt is kept in the refrigerator, it needs to be put back immediately after use.

In addition, since the peculiar smell in the refrigerator cannot be dissipated, it should also be stored in a closed container.
