What it is
Sodium nitrite is a white crystalline salt. It occurs naturally in some vegetables and is also produced industrially. It is often used in processed meats.
Why it's used
Sodium nitrite is primarily used as a preservative in processed meats like bacon, ham, and hot dogs. It helps prevent the growth of bacteria, particularly Clostridium botulinum, which causes botulism. It also contributes to the pink color and cured flavor of these products.
Health notes
Sodium nitrite is approved by the FDA for use in cured meats. The FDA has determined it is GRAS (Generally Recognized As Safe) when used as intended. Concerns have been raised about the potential formation of nitrosamines, which are carcinogenic, when nitrites react with amines at high temperatures. However, regulatory bodies like JECFA and EFSA have evaluated sodium nitrite and its role in cured meats, and its use is permitted within specified limits. The evidence regarding its health effects at typical consumption levels is still under review.
