Sodium Nitrite USP
Sodium Nitrite is an inorganic compound that appears as a white to slightly yellowish powder that is very soluble in water and is hygroscopic.
Sodium Nitrite is used as a food additive. As a color retention agent it is responsible for the desirable red color (or shaded pink) of meat. Acts as preservative; is well known for its role in inhibiting the growth of Clostridium botulinum spores in refrigerated meats. Also inhibits lipid oxidation that leads to rancidity.
