No matter what kind of food contains trace elements, the most trace element is sea salt, which is determined by the production technology and raw materials of sea salt. The production process of sea salt is to bring seawater into the beach field and use natural conditions such as sunlight and wind to evaporate and concentrate the precipitated sodium chloride.
The production process is pure natural green products. In the process of sea salt precipitation, trace elements in seawater will also be brought out with the precipitation of sodium chloride.
Seawater contains more than 80 kinds of elements, most of which are beneficial elements, because it is a slow process from seawater concentration on the beach to sodium chloride crystallization and precipitation, which takes about one year. During this period, most of the heavy metal elements in the concentrated seawater were greatly reduced.
The difference between sea salt and edible salt:
1. In terms of size, sea salt is thicker and more granular than salt, because it has not been processed so much. Sea salt is extracted by evaporating sea water. Salt is generally mined from underground salt mines and processed into finer crystals.
2. Nutrition: Some sea salts are not deeply processed like refined salt, so they can retain more trace elements. Generally, additives are added to the processed edible salt to make it difficult to solidify and agglomerate, so it lacks trace elements.
3. Color: According to the origin and minerals, the colors of sea salt are different, including white, pink, black, gray and variegated. Ordinary refined salt is usually made into white fine particles.
