Imidazole Standards (caramel coloring)

Over the past several years, there has been increased scrutiny of the caramel coloring used in food products, particularly cola-type soft drinks. There is concern of 4-methyl imidazole (4-MEI) that is created during the caramel synthesis process. The concern arises because 4-MEI has been reported to be carcinogenic in high doses.
