Sodium nitrite
What is Sodium nitrite?
Sodium nitrite is a salt and an anti-oxidant used primarily in the curing process of meats. It is chemically synthesized by neutralizing nitrous acid with sodium hydroxide, resulting in a white or slightly yellowish powder.
This compound is commonly used to preserve the color and flavor of cured meats like bacon, ham, and hot dogs. Its use is controversial due to the potential for nitrosamines, compounds that form when nitrites are exposed to high heat and are considered potentially carcinogenic. However, its antibacterial properties are well-documented, particularly against botulism.
When you see sodium nitrite on a label, it's typically there to enhance the safety and longevity of processed meats. Consumers interested in avoiding synthetic preservatives may want to check labels closely.
Commonly found in: Processed meats, Bacon, Ham, Sausages, Hot dogs, Canned meat
What to watch
- Sodium nitrite can form nitrosamines, which are linked to cancer in animal studies.
- High dietary intake of sodium nitrite has been associated with increased risk for certain types of cancer.
Benefits
- Provides protection against botulism in cured meats.
- Helps maintain the appealing pink color in processed meats.
The FDA allows its use in regulated amounts in cured meats, but acknowledges potential health risks related to nitrosamines.
Research shows that while nitrites are effective in inhibiting bacteria, they can form harmful compounds under certain conditions.
Sodium nitrite is not derived from animal products and is considered vegan-friendly.
Scout's take
Curing agent in the pepperoni. Forms N-nitrosamines in the stomach during digestion — IARC Group 1 (KNOWN human carcinogen). The 2015 WHO/IARC monograph on processed meat causally linked nitrite-cured meats to colorectal cancer.
