Blue salt in grains: characteristics and benefits
Whole grain rock salt is a naturally colored type of mineral. Its transparent grains are furrowed with streaks of bright blue, even intense, which make this salt particular but suitable for food use. The color is due to the presence of sylvite, a mineral that is part of the halite group of minerals, and is a crystalline variant of potash. It can be a colorless mineral, or yellow or pink in color, with blue shades in some declinations. Compared to most salts, the strong presence of potassium determines a rather strong initial salty taste. Soon the flavor disappears, leaving a mild taste in the mouth, and a spicy aroma. This blue salt in grains, due to its high potassium content, helps the body to regulate water balance, acidity levels and blood pressure.
Origins and History of the extraction
This “blue” salt was formed in very ancient times, over 200 million years ago, in which its structure probably changed due to the movements of the earth's crust. The color of the salt occurs during the formation of the crystalline structure, when great pressure is exerted on the salt deposits. It is due to the small amount of sylvite present in the structure, which makes the salt appear blue. Since the more finely ground the salt, the less blue it is perceived, the original rock salt is retained by its purity. The salt is collected without further processing, and is a particularly valuable salt. A few tons are produced every year, for this reason blue grain salt is one of the rarest salts. In addition, it is expensive for the extraction process (excavation, machinery) and for the crushing work. While leaving the rock salt whole, the large crystals must be reduced in the grains of the blue salt to be useful in the kitchen. The best known version of blue salt is extracted from an ancient cave located in Iran, where thanks to the sylvite it takes on bluish blue reflections.
Nutritional values of blue salt in grains
In this blue coarse salt, as in table salt, the main molecular compound is sodium chloride. Compared to classic refined table salt, however, blue salt includes minerals such as potassium, chlorine, and traces of calcium, iron and magnesium. Rock salt differs from classic table salt due to the absence of iodine.
