Less Than 0.1% As Food Preservative

This ingredient is sodium nitrite, a white crystalline powder. It occurs naturally in some vegetables and is also produced industrially. It is commonly used as a food additive.

Sodium nitrite is primarily used as a preservative in processed meats like hot dogs and sausages. It helps prevent the growth of harmful bacteria, such as Clostridium botulinum, and also contributes to the characteristic pink color and cured flavor of these products.

Sodium nitrite is approved by the FDA for use as a food additive. It is used in very small amounts, typically less than 0.1%. 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 the WHO/IARC and EFSA have evaluated nitrites, and evidence regarding their health effects at typical dietary intake levels is mixed. The FDA permits its use to prevent botulism, a serious foodborne illness.
