Foods Containing E332 (Potassium Citrates)
E332 (Potassium Citrates) is potassium salts of citric acid, used as a antioxidant to help stop fats and oils turning rancid and protect food colour and flavour. Here's where you're most likely to find it on food labels.
Common foods that contain E332
E332 is used across oils, margarine, snacks, cured meats, soft drinks and processed foods. The foods where it appears most often include:
- Oils
- Margarine
- Snacks
- Cured meats
- Soft drinks and processed foods
Exact usage varies by brand and recipe — the only way to know for certain whether a specific product contains E332 is to check its ingredients list, where it must be declared by law, either as "E332" or as "Potassium Citrates".
How to spot E332 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 "antioxidants: E332" or "antioxidants: potassium citrates". In the US the E-number system isn't used, so look for the full name "Potassium Citrates" instead.

E332 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 E332.
