Carbon dioxide

Function: Preservative

E290 is the European food-additive number for Carbon dioxide, a preservative — used to extend shelf life by slowing spoilage from microbes. CARBON DIOXIDE chemical formula CO2- is a colorless gas with a density about 60% higher than that of dry air.

What is E290 used for?

Carbon dioxide (E290) 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. See all preservatives (E-numbers).

Is E290 safe or restricted?

E290 is an approved food additive in the EU and currently carries no special regulatory restrictions in the EU additive register. Forkin classifies it as No regulatory flags and does not make health claims. See the methodology for how regulatory levels are assigned, or the guide to how EU additives are approved, re-evaluated and banned.

Is E290 vegan or vegetarian?

Carbon dioxide (E290) is typically produced from plant, mineral, or synthetic sources, so it is generally suitable for vegans and vegetarians.
