Product Description of Sodium Nitrite (CAS No. 7632-00-0)
Sodium Nitrite is closely related in name and function to sodium nitrate and is widely used as a preservative in processed meat products such as salami, hot dogs, and bacon. It plays an important role in maintaining color, flavor, and shelf life in cured foods.
Sodium Nitrite can be produced through several chemical synthesis routes involving the reduction of sodium nitrate. On an industrial scale, it is mainly manufactured by absorbing nitrogen oxides into aqueous solutions of sodium carbonate or sodium hydroxide, ensuring efficient and consistent large-scale production.

Product Application of Sodium Nitrite (CAS No. 7632-00-0)
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.
