Beet salt or beet salt is a type of kiln-dried mineral salt. Usually this mineral salt is mined in the form of rock from the saline soil around the Himalayas.
This substance, used as a spice, contains mainly sodium chloride, along with various other ingredients, from which it derives its color. Due to the presence of greigite (Fe3S4, ferrous (II,III) sulphide) in this mineral, it has a brownish pink to dark purple transparent crystal. Beet salt is mainly composed of sodium chloride and minor impurities of sodium sulfate, sodium bisulfate, sodium bisulfite, sodium sulfide, iron sulfide, and hydrogen sulfide.
Although beet salt can be produced with the necessary compounds in natural salt, it is now usually made synthetically. This is usually done by mixing sodium chloride with small amounts of sodium sulfate, sodium bisulfate, and ferric sulfate. It is then chemically oxidized with charcoal in a furnace. Similar products can be made by thermal methods of oxidation of sodium chloride, 5-10% sodium carbonate, sodium sulfate and some sugars.
