Sodium Nitrite
Function: Preservative
E250 is the European food-additive number for Sodium Nitrite, a preservative — used to extend shelf life by slowing spoilage from microbes. SODIUM NITRITE is an inorganic compound with the chemical formula NaNO2.
What is E250 used for?
Sodium Nitrite (E250) is a preservative — used to extend shelf life by slowing spoilage from microbes. It is added during food production for a technological purpose rather than for nutrition.
Is E250 safe or restricted?
E250 is banned or severely restricted in one or more jurisdictions. Forkin classifies it as “Banned / Severely restricted” and does not make health claims. See the methodology for how regulatory levels are assigned.
Frequently asked questions about E250
- What is E250?
- E250 is the E-number for Sodium Nitrite, a preservative — used to extend shelf life by slowing spoilage from microbes. SODIUM NITRITE is an inorganic compound with the chemical formula NaNO2.
- What is E250 used for?
- Sodium Nitrite (E250) is a preservative — used to extend shelf life by slowing spoilage from microbes. Manufacturers add it during processing rather than for nutrition. The Forkin app shows which products in your scan history actually contain it.
- Is E250 vegan or vegetarian?
- It depends on the source. Many additives can be produced from plant, mineral, or animal-derived raw materials, and the ingredient list rarely states which was used. The Forkin app shows the verified vegan and vegetarian status per product where it's known, instead of a blanket guess.
- Is E250 safe, and is it banned anywhere?
- E250 is banned or severely restricted in one or more jurisdictions. Forkin classifies it as "Banned / Severely restricted" and does not make health claims — see the methodology page for how regulatory levels are assigned, and the Forkin app for the full profile, including acceptable daily intake (ADI) and restrictions by country.
