Foods Containing E133 (Brilliant Blue FCF)
E133 (Brilliant Blue FCF) is a synthetic triarylmethane dye, used as a food colouring to help add or restore colour to foods and drinks. Here's where you're most likely to find it on food labels.
Common foods that contain E133
E133 is used across sweets, soft drinks, desserts, ice cream, sauces and snacks. The foods where it appears most often include:
- Sweets
- Soft drinks
- Desserts
- Ice cream
- Sauces and snacks
Exact usage varies by brand and recipe — the only way to know for certain whether a specific product contains E133 is to check its ingredients list, where it must be declared by law, either as "E133" or as "Brilliant Blue FCF".
How to spot E133 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 "food colourings: E133" or "food colourings: brilliant blue fcf". In the US the E-number system isn't used, so look for the full name "Brilliant Blue FCF" instead.
