Potassium ferricyanide is added in order to avoid the caking of table salt.

Commonly used salt anti-caking agents are potassium ferricyanide, potassium ferric citrate, calcium silicate, silicon dioxide, etc. At present, the most widely used is potassium ferricyanide.

After the addition of potassium ferricyanide to table salt, the hexahedral crystallization of table salt is transformed into stellate crystals, thus it is not easy to agglomerate, and it has the performance of anti-caking, which can prevent the fine powder and crystalline food from agglomeration.

Edible salt, from the classification of well salt, sea salt, pool salt, rock salt, etc., from the point of view of the ingredients contained in a variety of nutrients, including iron, calcium, zinc, potassium, sodium, iodine, etc., people use table salt is a kind of salt, refers to sodium-rich salts, that is, sodium chloride.

Types of salt:

1, iodized salt

Iodized salt is to give some of the iodine-deficient areas of the people, in the life of people who can eat food will be able to eat food can be supplemented with iodine elements needed by the body.

2, non-iodized salt

Non-iodized salt is in the salt does not add any iodine content, in the iodine more areas, you can consume this non-iodized salt, which is in order to differentiate from iodized salt.

3, low-sodium salt

The main component of salt is sodium chloride, which is the sodium ion component is to provide us with a salty taste of the material. Low-sodium salt as the name suggests is to reduce the sodium content of table salt, so low-sodium salt can also be understood as light salt.

4, well mine salt

Well mine salt extraction method is more cumbersome, the extraction of the original place is also very different. Well mine salt from the mine in the saturated brine, through filtration and distillation and other technologies, in addition to harmful substances, and finally left only the salt crystals, which is the well mine salt.
