Product Introduction:

Salt nitrite (NaNO ₂) is an inorganic salt developed by the mix of nitrite ions and additionally salt ions.

Salt nitrite powder is rapidly deliquescence, easily soluble in water as well as liquid ammonia, its fluid treatment is alkaline, somewhat soluble in ethanol, methanol, ether and additionally various other natural solvents.

When subjected to air, sodium nitrite responds with oxygen to form salt nitrate.When heated to above 320°C, it will decompose and generate nitrogen dioxide, nitric oxide and sodium oxide.

Nitrogen atoms and oxygen atoms in nitrite have lone pairs of electrons and have the ability to form coordination bonds, so nitrite can be used as a ligand to form coordination compounds with many metal ions.

Sodium nitrite and nitrite are widely found in the human environment and are the most prevalent nitrogen-containing compounds in nature.

Product Usage:

As An Additive

  • Food quality salt nitrite (NaNO2) is just one of the most typically used preservative in the manufacturing of meat products.
  • As a food additive, sodium nitrite is allowed to be added to cured meat products, marinated meat products, smoked barbecue meat, fried meat, western-style ham, meat sausage, fermented meat products, canned meat and meat processing. .
  • The characteristics of Sodium Nitrite Powder are that it can increase the freshness of meat, and has the effect of inhibiting microorganisms, which helps to maintain the structure and nutritional value of meat products.

Used As Colorant, Preservative

  • Salt Nitrite can be used in canned meat and meat products. In meat products, it has a specific impact on preventing the expansion of microorganisms (particularly hindering Clostridium botulinum), as well as can improve the flavor of healed meat.
  • It frees nitrous acid under the action of lactic acid consisted of in meat, and then breaks down nitroso (- N0), which can create bright red nitroso-myoglobin with myoglobin and contribute in shade protection. And can generate special flavor.

Medicinal Use

  • Recent studies have found that sodium nitrite has a significant effect on dilating blood vessels and improving blood circulation, including application prospects for sickle cell disease, cyanide poisoning, myocardial infarction, cerebral aneurysm and pulmonary hypertension.

Industrial Applications

  • Sodium nitrite powder is used for the conversion of amines to diazonium compounds, and the N2 group has good leaving properties, and such reactions are used to replace amino groups in production applications.
