Citrus Red 2, Citrus Red No. 2, C.I. Solvent Red 80, or C.I. 12156 is an artificial dye. As a food dye, it has been permitted by the US Food and Drug Administration (FDA) since 1956 to color the skin of oranges.[1][2][3] Citrus Red 2 is listed by the International Agency for Research on Cancer (IARC) as a group 2B carcinogen, a substance "possibly carcinogenic to humans".[4]

Properties[edit]

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[edit]

Citrus Red 2 is used to color early-season, ripe fruit, that haven't been exposed to cold enough weather to produce the characteristic orange skin.[5]
