Sodium Nitrite Smoke Flavoring

Sodium nitrite smoke flavoring is a food additive that combines sodium nitrite, a curing salt, with concentrated smoke flavoring. Sodium nitrite is a chemical compound, while smoke flavoring is made by capturing and concentrating the compounds found in wood smoke.

This ingredient is primarily used as a preservative and to add a smoky flavor to foods. Sodium nitrite helps prevent the growth of harmful bacteria, especially those that cause botulism, and also contributes to the characteristic pink color and flavor of cured meats. It is commonly found in cured products like bacon, sausages, and deli meats.

Sodium nitrite is an FDA-approved food additive used in cured meats. JECFA (the Joint FAO/WHO Expert Committee on Food Additives) has evaluated sodium nitrite and established an acceptable daily intake. EFSA (the European Food Safety Authority) has also evaluated its safety. There is some concern that nitrites can react with amines in meat to form nitrosamines, which can be harmful, especially under high-heat cooking. However, manufacturers often add antioxidants like ascorbate or erythorbate to cured meats to help reduce nitrosamine formation.
