Eating salt, also known as table salt, is one of the most important substances for human survival, but also the most common seasoning in cooking. The key organic chemical component of salt, sodium oxide (chemical formula NaCl), is 99% in table salt, and potassium chloride is added to table salt produced in some regions to reduce the sodium oxide component and reduce the incidence of high blood pressure. In addition, the vast majority of the world's salt is based on the addition of iodine to prevent iodine deficiency disorders, and the addition of iodine to the salt is called sea crystal salt.
General salt contains raw salt and wind-blown and sun-dried meticulous salt.
Table salt is pure sodium oxide. And table salt contains residual potassium chlorate, taking the gift of adding some special salt seasoning is sodium oxide, potassium iodate, anti-agent. Therefore table salt is is edible salt. Only is table salt is also iodized today.
It is best not to have to use it for cleansing! Due to the high concentration of salt solution produced by melting table salt into water, the skin's body cells are very easy to seep into the water shortage, resulting in stormy skin! But you can use a little bit of salt to wash the blackheads and pimples on the nose, the actual effect is generally, because of its particulate matter is large, able to rub out some of the dirt, but should be applied to boiled water
Raw salt that is the sea, lake salt area production of raw salt.
Wind-blown sun-dried meticulous salt refers to China's southern Fuqing District based on the characteristics of high average temperature, frequent rainfall, the choice of new brine, thin sunshine, short-term crystallization, regular activities of the brine and salt ballast processing technology, the release of granularity well-proportioned fine salt.
Table salt, also known as special salt, is pure natural brine from the ground, rock salt water-soluble extraction of brine obtained and melting of raw salt made of brine as raw materials, organic chemical way to remove the soluble residue in which, in response, and then by volatilization, crystallization, dehydration, dry agitation, screening and become. In the well mine salt area, the brine obtained from the water-soluble extraction of rock salt or the pure natural brine from the ground is used as the raw material to produce special salt. In the special salt that has been selected through the process, appropriate anti-caking agents are added and stirred well to turn it into table salt. The salt does not carry residue.
