The truth about the taste change in the tangerine-flavoured drink finally emerged when Coca-Cola yesterday confirmed to the Irish Examiner that the colourant Quinoline Yellow has been scratched from the original, ancient recipe.
The colourant, a yellow food dye, is already banned in several European countries as well as in the US. In Britain, the Hyperactive Children’s Support Group recommends it be eliminated from children’s diets.
Yesterday, a spokesperson for Coca-Cola, the manufacturers of a drink not sold outside Co Cork, said the decision to remove Quinoline Yellow — E104 — from the original recipe was on foot of a University of Southampton study “which did recent research into different colourants and said Quinoline Yellow may cause hyperactivity in children”.
The research, published in 2007, found evidence of increased levels of hyper-activity in young children who consumed mixtures of some artificial food colours, including Quinoline Yellow.
“Coca-Cola constantly reviews their ingredients and their first duty of care is to the consumer and that is why they came to the decision to remove Quinoline Yellow,” the spokesperson said.
It now remains to be seen how Coca-Cola will reformulate Tanora to restore its previous taste if that is what Corkonians vote for as part of an ongoing taste test.
