What is Sodium Nitrate?
Sodium nitrate (NaNO₃) is a white crystalline salt made of sodium, nitrogen, and oxygen. It is naturally found in mineral deposits (like Chile saltpeter) and is used in food, fertilizers, and industry.
Role in Food Preservation
Sodium nitrate is mainly used as a curing agent and preservative in meat and fish products.
It prevents spoilage and keeps food safe and appealing for longer periods.
Common Food Products That Use Sodium Nitrate
.Ham
.Bacon
.Salami and sausages
.Corned beef
.Cured fish
.Hot dogs and luncheon meats
Health and Safety Considerations
Excess consumption can lead to the formation of nitrosamines, compounds linked to cancer risk.
Therefore, its use is strictly regulated by food authorities (like FSSAI, FDA, and EFSA).
Many producers now add ascorbic acid (Vitamin C) to reduce nitrosamine formation.
egetable-derived nitrate salts: Celery powder/extracts contain high levels of naturally occurring nitrate and are used in some “uncured” or “no-nitrite-added” labeled products. Chemically they still provide nitrate that converts to nitrite, so the chemistry and risk profile are similar.
