Consumer Advice
Citrus Red 2 is a synthetic azo dye permitted only in the United States, where it is used under strict limits to colour the peel of Florida oranges that are not intended for processing. It is not approved for food in the European Union, China or most other regions. Because it colours the peel rather than the flesh, the risk from normal consumption is very low.
