Sodium Nitrite (E250)

Sodium Nitrite Sodium nitrite is an inorganic salt produced by absorbing nitrogen oxides in sodium carbonate solution or through catalytic oxidation of ammonia, used as a curing agent, color fixative, and antimicrobial preservative (E250) that forms nitric oxide for pink color development, inhibits Clostridium botulinum, and prevents rancidity. In the food industry, it provides characteristic cured meat color, flavor enhancement, and botulism protection ideal for processed meats and sausages.
