Yes, there is a situation in fake salt.

fake salt usually refers to the illegally produced and sold salt products, which may be shoddy, doped with other ingredients or processed in an irregular way.

Some fake salt will be mixed with some non-edible substances, such as gypsum, sand and cinder. These dopants not only reduce the quality of salt. Some fake salt may pass off low-quality salt as high-quality salt, and cheat by means of similar appearance or labels. Some fake salt may be processed in an informal or illegal way without strict quality control and hygiene inspection. This may lead to the existence of harmful substances such as bacteria and heavy metals.

and fake salt has poor solubility in water. Normal salt should be able to dissolve in water quickly and completely, while fake salt may dissolve slowly or partially remain.

When buying salt, there are several ways to avoid buying fake salt:

1. Choose regular channels to buy salt: try to choose regular and reputable supermarkets, food stores or brands to avoid buying salt from unknown sources.

2. Check the packaging marks: the packaging of regular salt should have obvious information such as trademark, production date, shelf life, address and contact information. Check the package carefully when buying, and avoid buying unmarked or unclear salt.

3. Pay attention to the color and crystallinity of salt: normal salt should be white without impurities. If it is found that the color of salt is abnormal (such as graying, yellowing, etc.), or the crystallinity is poor, it may be problematic salt, so you should buy it carefully.

4. Pay attention to the smell of salt: normal salt should be tasteless or slightly salty. If you find that salt has an odor (such as moldy and unpleasant smell), it may be problematic salt, so you should avoid buying it.
