Origin and production
It is manufactured by chemical synthesis from petroleum-derived aromatic compounds, followed by purification to meet food-grade specifications.
Why is it used?
Allura red gives a vivid red colour to sweets, chewing gum, cake decorations, desserts, soft drinks and some snacks. It is especially common in products sold in the United States, where it is known as Red 40.
Vegan, vegetarian and halal
Allura red is synthesised without animal ingredients and is suitable for vegans and vegetarians. It raises no particular halal or kosher issue.
Safety and regulation
Allura red is authorised in the EU with maximum levels per food category, and was re-evaluated by EFSA. It is one of the six 'Southampton' colours, so foods containing it in the EU must carry the warning 'may have an adverse effect on activity and attention in children'.
