The nature and the person know two types of food salt: cooking and stone which version is also sea salt. It is actually a little differences in these two types, however areas of application cardinally differ.
Human physiology such is that such ordinary and, apparently, the inexhaustible element as salt, becomes the vital component of daily existence for this reason it is so difficult to exaggerate the importance of process of production and processing of a product with rather known chemical name and a formula NaCl.
Lack of salt of an organism - an inevitable and direct way to a viability loss and death of the person for this reason since ancient times deprivation of the captive of an opportunity to receive enough salt from the outside was considered as the most painful and cruel torture.
Sodium rock salt
In the nature sodium rock salt exists in the form of the special minerals or sedimentary rocks which are containing a considerable share of additional impurity and minerals and lying at a depth from hundred to thousands meters. Rich with iron, manganese and chrome, rock salt has the white, gray, yellow or even brown color caused by such impurity as clay, bitumen, iron oxides.
From the rock salt which literally is cut down from rocks and given on the Earth's surface by special conveyors at special solepererabatyvayushchy plants by cleaning also receive habitual table salt.
Rock salt has huge economic value for many countries which are engaged in production and export of this element which is widely applied to receiving soda and chlorine. The food industry, aircraft industry, nuclear power, tinctorial business, soap manufacture - here only a part of the industries where rock salt finds direct application in the initial natural look.
Food NaCl
Processed, turned into cooking and often the salt which is in addition enriched with potassium fluoride, coming to a human body, as a rule, with food, it is not only an important source of the vital minerals: - is a part of blood and a lymph; - regulates many exchange processes; - is an important source of hydrochloric acid, a component of many important secrets.
It is accepted to call the purified rock salt table, it is white. Crude always has a shade, is more often - gray which minerals in its structure give.
The disinfecting and cleaning properties of salt allow to use this product for prevention and even treatment of many diseases. Salt wrappings, salutary bathtubs and even the physiological solution which is widely applied in medicine - all this a salt merit. What to tell about house and industrial conservation, salting and different ways of preparation of products which would be simply impossible be not in kitchen of usual table salt.
