Properties
Citrus Red 2 is an orange to yellow solid or a dark red powder with a melting point of 156 °C. It is not soluble in water, but is readily soluble in many organic solvents.
Use
In the United States, Citrus Red 2 is sometimes used to color oranges. It is only permitted to be used on the peel.[1] It is permitted when the fruit is intended to be eaten, but is not permitted when the fruit is intended or used for processing, for example to manufacture orange juice.[2] It is used on some oranges from the US state of Florida but is banned in the US states of California and Arizona.[citation needed]
