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 appears to cause allergic or intolerance reactions, particularly amongst those with an aspirin intolerance. Other reactions can include a rash similar to nettle rash and skin swelling. Asthmatics sometimes react badly to it.
It is one of the colourants that the Hyperactive Children's Support Group recommends be eliminated from the diet of children.
