What it is
Sodium nitrite is a white to yellowish crystalline powder. It is a salt of nitrous acid, commonly produced industrially by reacting nitrogen oxides with sodium carbonate or sodium hydroxide.
Why it's used
Sodium nitrite is primarily used as a preservative and color fixative in cured meats like bacon, ham, and hot dogs. It prevents the growth of harmful bacteria, particularly Clostridium botulinum, and gives cured meats their characteristic pink color and flavor.
Health notes
Sodium nitrite is approved by the FDA as a food additive. Regulatory bodies like JECFA and EFSA have evaluated its use. Concerns have been raised about the potential formation of nitrosamines, which are carcinogenic, when nitrites react with amines at high temperatures. However, evidence regarding the health effects of nitrites at typical dietary intake levels is mixed, and they are considered safe when used within permitted limits.
