Foods Containing E535 (Sodium Ferrocyanide)
E535 (Sodium Ferrocyanide) is a synthetic anti-caking salt used in table 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 E535
E535 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 E535 is to check its ingredients list, where it must be declared by law, either as "E535" or as "Sodium Ferrocyanide".
How to spot E535 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: E535" or "anti-caking agents: sodium ferrocyanide". In the US the E-number system isn't used, so look for the full name "Sodium Ferrocyanide" instead.
Should you avoid foods containing E535?
E535 is considered safe. It is authorised across the EU, UK and US, and safety evaluations by the European Food Safety Authority (EFSA) have not identified health concerns at the levels used in food. For most people there is no reason to avoid E535.
