Is sel nitrité e250 vegan?

"Sel nitrité e250" is a French label term meaning nitrite curing salt, which is a blend of common table salt and sodium nitrite (food additive E250). Sodium nitrite is produced synthetically through the chemical reaction of nitrogen oxides with aqueous sodium carbonate or sodium hydroxide. The salt base is obtained through standard mineral mining or the evaporation of seawater.

Manufacturers primarily use this additive as a preservative and color fixative in cured meats, including bacon, ham, and sausages. However, it can also appear in processed plant-based meat alternatives to extend shelf life and prevent bacterial spoilage, particularly from Clostridium botulinum.

Sel nitrité e250 is vegan because both of its active components are derived entirely from mineral and synthetic sources. No animal tissues, animal-derived processing aids, or animal byproducts are involved at any point in the manufacturing process.
