Product Description of Sodium Nitrite CAS#7632-00-0

Sodium Nitrite is similar to sodium nitrate in name and function. It is widely used as a preservative in processed meats including salami, hot dogs and bacon, maintaining the color, flavor and shelf life of cured foods. It can be synthesized by reducing sodium nitrate via multiple chemical routes. Industrially, it is mainly produced by absorbing nitrogen oxides into sodium carbonate or sodium hydroxide aqueous solution for high-efficiency and stable production.

Sodium Nitrite is the sodium salt of nitrous acid and is widely used as an antimicrobial agent and food preservative. It is typically supplied as a slightly yellow granular powder or an off-white opaque solid, and it is hygroscopic, readily absorbing moisture from the air. The product is highly soluble in water, allowing easy incorporation into processing solutions.

In the food industry, Sodium Nitrite is mainly applied in meat curing to fix and stabilize color and to enhance the characteristic flavor of cured products, while also helping to inhibit microbial growth and extend shelf life.
