Foods Containing E319 (TBHQ)
E319 (TBHQ) is a synthetic antioxidant, 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 E319
E319 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 E319 is to check its ingredients list, where it must be declared by law, either as "E319" or as "TBHQ".
How to spot E319 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: E319" or "antioxidants: tbhq". In the US the E-number system isn't used, so look for the full name "TBHQ" instead.
Should you avoid foods containing E319?
E319 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 E319 is not considered harmful.
