Comment: Every time, being in these places, it attracts like a magnet, the kind of pink pools, huge spaces, it hypnotizes. Moreover, the pink shade of water is a purely natural phenomenon, without human intervention. The intervention is only wooden equipment of the old salt industry, where salt has been mined for more than 2500 years. The photo shows an abandoned "check" (salt pool) on Sasyk-Sivash lake near the city of Evpatoria. The name of the reservoir received for the pink hue of water, which is formed due to the unusual sea salt. As a result of the evaporation of water, this salt acquires a pink color, as the Dunaliella Salina microalga grows in the lake, releasing beta-carotene and another 30 other carotenoids. It is the concentration of beta-carotene that determines the color of the water. Salt lake has a pinkish tint, is used in food and is considered a "living" salt, as it contains 88 minerals in contrast to the usual rock salt (NaCl). Strong solar radiation, summer heat, high salt concentration in water, lack of nutrients - in such extreme conditions, microalgae Dunaliella Sallina adapted to survive, producing more than 30 different carotenoids, most of which is occupied by? -Carotene (beta-carotene). The salt of Sasyk-Sivash lake contains a lot of iodine, fluorine, selenium, iron, magnesium, etc. Being inside the crystal structure, natural additives are “conserved” in it and are not in contact with the external environment, thereby the shelf life of the salt increases significantly, as does the benefit of the product. According to the analysis of the chemical laboratory of Moscow State University, in addition to the microelement composition, the salt contains natural beta-carotene produced by the microalga Dunaliella Sallina. Being in the composition of sea salt, beta-carotene does not cause allergies and has no side effects and contraindications in the application for humans. ? -carotene is a provitamin A, provides a high level of vital activity of the human body. Unlike vitamin A,? -Carotene is not toxic even at the highest dosages. ? -Carotene is an immune system stimulant and antioxidant that can prevent the occurrence of cancers of the breast, skin, cervix, lung, colon, bladder. Like vitamin A,? -Carotene plays an important role in the formation of the epithelium of the skin, glands, mucous membranes of the respiratory organs, the digestive tract and the urinary tract in humans. ? -carotene provides protection against heart disease, atherosclerosis and paralysis. Depending on the concentration of beta-carotene excreted by Dunaliella Sallina in the lake brine, the water of Sasyk-Sivash lake may change color from pink to red. In 1912, at the World Industrial Exhibition in Paris, thanks to its high qualities, the pink salt of Lake Sasyk-Sivash brought Russia a gold medal.
