Foods Containing E554 (Sodium Aluminium Silicate)
E554 (Sodium Aluminium Silicate) is a synthetic mineral salt, used as a anti-caking agent to help stop powders and granules clumping together. Here's where you're most likely to find it on food labels.
Common foods that contain E554
E554 is used across table salt, spice mixes, powdered drinks, grated cheese and dry mixes. The foods where it appears most often include:
- Table salt
- Spice mixes
- Powdered drinks
- Grated cheese and dry mixes
Exact usage varies by brand and recipe — the only way to know for certain whether a specific product contains E554 is to check its ingredients list, where it must be declared by law, either as "E554" or as "Sodium Aluminium Silicate".
How to spot E554 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 "anti-caking agents: E554" or "anti-caking agents: sodium aluminium silicate". In the US the E-number system isn't used, so look for the full name "Sodium Aluminium Silicate" instead.
Should you avoid foods containing E554?
E554 is approved for use in the EU, UK and US at regulated levels, but some concerns or conditions apply. For most people, normal dietary exposure to E554 is not considered harmful.
