The list includes companies that have product ranges that have never contained the six colours and companies that have reformulated their product ranges to remove the colours. The colours, identified by a Southampton University study financed by the Food Standards Agency, are:
- sunset yellow FCF (E110)
- quinoline yellow (E104)
- carmoisine (E122)
- allura red (E129)
- tartrazine (E102)
- ponceau 4R (E124)
The FSA is publicising the product ranges to encourage the food industry to participate in the voluntary ban. The voluntary ban was agreed by ministers in November 2008.
Consumers who are particularly concerned about the presence of the colours should continue to check labels, especially in the case of products with a long shelf-life, where the availability of reformulated products may vary.
