Foods Containing E228 (Potassium Bisulphite)
E228 (Potassium Bisulphite) is a synthetic sulphite salt, used as a preservative to help prevent spoilage by stopping the growth of bacteria, moulds and yeasts. Here's where you're most likely to find it on food labels.
Common foods that contain E228
E228 is used across soft drinks, dried fruit, processed meats, sauces, baked goods and wine. The foods where it appears most often include:
- Soft drinks
- Dried fruit
- Processed meats
- Sauces
- Baked goods and wine
Exact usage varies by brand and recipe — the only way to know for certain whether a specific product contains E228 is to check its ingredients list, where it must be declared by law, either as "E228" or as "Potassium Bisulphite".
How to spot E228 on a label
In the UK and EU, additives must appear in the ingredients list with their function and either their E-number or full name — for example "preservatives: E228" or "preservatives: potassium bisulphite". In the US the E-number system isn't used, so look for the full name "Potassium Bisulphite" instead.
Should you avoid foods containing E228?
E228 is approved for use in the EU, UK and US at regulated levels, but some concerns or conditions apply. Sulphites are among the 14 major allergens that must be declared on food labels, because they can trigger asthma attacks and allergic-type reactions in sensitive people. For most people, normal dietary exposure to E228 is not considered harmful.
