Lake salt is better than sea salt.

Sea salt is actually salt extracted from seawater, an average of 1,000 kilograms of seawater can produce 27 kilograms of salt, occupying 80% of the national production of salt, but with the increasing demand for salt purity, the production of sea salt is also lower and lower.

This is mainly because there are more impurities in sea salt, and if you want to improve the purity, you need to spend a lot of energy to accomplish it, coupled with the large demand for sea salt sites, there are few suitable sites to complete the production of sea salt, but compared to lake salt, it is a large area of origin, and less pollution around it, it is more convenient to extract high purity of salt, which also guarantees the quality of salt.

Buying salt notes

1, choose the type. Salt on the market can be roughly divided into iodized salt, non-iodized salt, fortified nutritional salt these categories. Coastal residents often consume seafood that contains a lot of iodine, so you can choose non-iodized salt. If you find thyroid abnormalities such as a thick neck, you should go to the hospital to check whether you have too much iodine or a lack of iodine, and choose salt accordingly.

2. Look at the color. When observing the color of salt, you should spread a thin layer of the sample on the paper and carefully observe its color. Good quality salt color white, second quality salt color gray or yellowish, poor quality salt is dark gray or yellowish brown.

Generally speaking, good quality salt without any odor, the second quality salt without odor or mixed with a slight odor, poor quality salt has a strange odor or other foreign odors.
