Another common source of table salt is evaporated sea water. Sea salt consists mainly of sodium chloride, with trace amounts of magnesium and calcium chlorides and sulfates, algae, sediments, and bacteria. These substances impart a complex flavor to sea salt. Depending on its source, sea salt may contain pollutants found associated with the water source. Also, additives may be mixed in with sea salt, mainly to make it flow more freely.
Whether the salt source is halite or the sea, the products contain comparable amounts of sodium, by weight. In other words, one cannot be used in place of the other to lower dietary sodium.
One of the most common additives is iodine in the form of potassium iodide, sodium iodide, or sodium iodate. Iodized salt may contain dextrose (a sugar) to stabilize the iodine. Iodine deficiency is considered the biggest preventable cause of mental retardation. Salt is iodized to help prevent cretinism in children as well as hypothyroidism and goiter in adults. In some countries, iodine is routinely added to salt (iodized salt) and products that do not contain this additive may be labeled "uniodized salt," Uniodized salt has not had any chemicals removed from it; rather, this means supplemental iodine has not been added.
Another common additive to table salt is sodium fluoride. Fluoride is added to help prevent tooth . This additive is more common in countries that don't fluoridate water.
"Doubly-fortified" salt contains iron salts and iodide. Ferrous fumarate is the usual source of iron, which is added to help prevent iron-deficiency anemia.
Another additive may be folic acid (vitamin B9). Folic acid or folicin is added to help prevent neural tube defects and anemia in developing infants. This type of salt may be used by pregnant women to help prevent common birth defects. Folicin-enriched salt has a yellowish color from the vitamin.
After drying the seawater with solar energy, crystalline sea salt is produced. After 600 million years of geological squeezing and underground high temperature action, the underground minerals and sea salt are combined to form a "salt fossil"-mineral salt and mineral salt can be said to have no Pollution,
Mining process:
1: Therefore, it is necessary to drill first, after reaching the position of the salt mine, use the pipe to inject water to dissolve the salt mine into brine, and then extract the brine to perform a series of evaporation and drying processes," Lu Jinhua said. Simply put, the production process of well mineral salts is the process of dissolution and recrystallization. The whole process is relatively simple, and there are few human interventions. Therefore, the produced salt is environmentally friendly, healthy, and not he raw materials produced by the enterprise are derived from the Dawenkou underground rock salt mine formed in the ancient Cretaceous period, with a buried depth of about 1,000 meters, natural and pollution-free, high ore grade, and an average ore grade of 86.76%. The production process adopts the domestic advanced five-effect vacuum evaporation salt production process. The main equipment evaporation tank, dehydration machine, drying bed, etc. are all titanium or stainless steel. The production control adopts DCS automatic control system, and the process flow is fully automated and mechanized.
