1, lake salt
Lake salt, also known as "pool salt", is made by drying raw materials of inland saltwater lakes or salt lakes in salt fields, and the general process is basically the same as sea salt. Generally, the salt content in salt lakes is more than 3.5%. Due to the different mineral components and algae in the lakes, the salt fields show colorful colors such as cyan, white, red, blue and black under the combined action of high temperature and light.
Lake salt, like sea salt, is distributed in shallow layer, with more impurities and less purity than mineral salt. However, because the salt particles are large and not easy to agglomerate, there is no need to add anti-caking agent.
2. Mineral salt
Mineral salt refers to the salt mined from underground and formed after processing. It is buried deep in the ground100-3000m, and can only be made by drilling, water injection, dissolution and extraction. Due to the improvement of drilling technology and drying technology, the output of mineral salt is also very considerable at present.
Mineral salt is easy to agglomerate due to its fine particles, so a little anti-caking agent has to be added to prevent agglomeration. Mineral salt is a fully mechanized production mode, with high output and good quality, white salt, round particles and higher sodium chloride content than other types.
3. Well salt
Well salt is the salt obtained by extracting shallow surface or underground natural brine by sinking method. The depth of the well is shallower than that of the rock mine, generally ranging from tens of meters to hundreds of meters. You know, what you take out of the well is not massive salt, but dark and thick bittern. Boil this brine in a large pot and you will get the white salt we see.
The method of distinguishing salt is:
1, look at the packaging
Salt is a common sense, and it is also the earliest salt production and manufacturing center in China. In China, there are many kinds of salt. However, salt in our country is basically made of salt, not all salt, but some salt packages are marked with salt.
If it is in use, we can tell whether it is true or false by the packaging of salt. When we buy salt, we must be careful not to buy fake salt, because the quality of salt is different. When we buy salt, we must be careful not to buy fake salt.
2. Look at the packaging
The packaging of salt is actually unpacked, and there are no words on the packaging. However, there are certain differences in the packaging of fake salt and the fonts on the packaging. Moreover, the packaging on the packaging is relatively neat, and there is no obvious regularity. When buying salt, we must be careful not to buy fake salt.
3. Look at the color
In salt, there are certain chemical elements. Therefore, we must pay attention to it. There are still some chemicals in salt. When we buy salt, we must pay attention.
4. Look at the weight of salt
The weight of salt is very important, because the salt content of salt is very heavy, and it will not be easily consumed when we eat, but the weight of salt is very important. When we usually eat salt, we can use it to measure it. If it contains salt, it can be said to be salt. If not, the weight of salt may be real salt.
