Azorubine is a synthetic red food dye from the azo dye group. It is a red to maroon powder. It is used for the purposes where the food is heat-treated after fermentation. It has E number E122.
Some of the foods it can be present in are blancmange, marzipan, Swiss roll, jams, preserves, yoghurts, jellies, breadcrumbs, and cheesecake mixes. It is also present in Oraldene Mouthwash.
Azorubine is commonly used in the UK, but it is a prohibited food additive in Japan, Norway, and the United States. A study commissioned by the UK's Food Standards Agency found that when used in a mixture of other preservatives, increased levels of hyperactivity in children were observed.
