Is E228 safe?
E228 is authorised in the EU and UK but carries genuine concerns. E228 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 Potassium Hydrogen Sulphite 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.
