Erythrosine
The short version
A cherry-pink iodine-based dye best known in cocktail cherries; US authorization is being withdrawn.
A synthetic pink/red dye (Erythrosine). It contains iodine and high intakes have raised thyroid questions in animal studies, so its use is tightly restricted. That's why we flag it.
Where it comes from
A synthetic cherry-pink xanthene dye that contains iodine (FD&C Red No. 3).
How it's used
Bright pink-to-red colorant, most familiar in cocktail and candied cherries, and in some sausages, sweets, and cake decorations.
Safety profile
ADI 0.1 mg/kg body weight (JECFA). High doses affected the thyroid in animal studies (it is iodine-rich), so its uses are restricted. In January 2025 the US FDA moved to revoke its authorization for use in foods.
Physical & chemical properties
Brown-red powder giving a bluish-pink solution; not light-stable and fades at low pH.
Regulation worldwide
EU-permitted for limited uses (mainly cocktail cherries); US food authorization being withdrawn.
