Allura Red AC (E129)

Allura red AC is a synthetic red azo dye. EU foods that contain it must carry the warning about activity and attention in children.

What it is

It colours soft drinks, sweets, desserts, sauces and snacks red or orange. On labels it appears as allura red AC or E129.

How IngrediScan rates it

These levels come from the fixed rules in the IngrediScan app. A low level means the rules found little or no concern for that profile. It does not mean the ingredient is safe for everyone.

EFSA's 2009 re-evaluation kept the acceptable daily intake at 7 mg per kg body weight per day. For adults the app notes possible dye intolerance. For children and infants it uses the Southampton findings, where the evidence is limited.

Basis of the ratings: limited or mixed data, errs on safety.

Possible concerns: Allergenic, Hyperactivity in children.
