Foods Containing E220 (Sulphur Dioxide)
E220 (Sulphur Dioxide) is a preservative and allergen — sulphites must be declared on labels when present at over 10mg/kg, and are the main food trigger for asthma. Here are the foods where you'll find it on the label.
Common foods that contain E220
- bread and baked goods
- wine and cider
- cured meats
- cheese
- pickles and condiments
- soft drinks
In the UK and EU, E220 must be declared either as "E220" or as "Sulphur Dioxide" in the ingredients list.
Is E220 safe?
E220 is authorised in the EU and UK but carries genuine concerns. E220 is a sulphite or sulphite-related additive — sulphites are declared allergens that can trigger asthma and respiratory reactions in sensitive people (estimated 5–10% of asthmatics). For most people consuming Sulphur Dioxide in typical quantities, health effects are unlikely — but the caution flag reflects either active scientific debate, mandatory warning labels, allergen status, or conditions attached to its authorisation.
