Food orange 7, the ethyl ester of beta-apo-8'-carotenic acid, is a carotenoid with an orange-red color. It is found in small quantities in some plants, but is often produced commercially from apocarotenal (E160e). It is used as a food coloring under the E number E160f and is approved for use in Australia and New Zealand. It was approved for use in the EU, but was delisted in November 2011 as it was no longer being manufactured.
