Is it vegan?

Annatto (E160b)

Annatto is the orange in a lot of cheddar and snack dust. It comes from a seed, so on the vegan test it is a clear pass, even when the food around it is not.

Where it hides

  • Orange cheeses and butters
  • Snacks and crackers
  • Smoked fish and margarine
  • Rice and Latin American dishes

What it is

Annatto is the deep orange colour pressed from the seeds of a tropical tree, used for centuries as both dye and seasoning.

Primary source 01 / 01

Annatto ( or ) is an orange-red condiment and food coloring derived from the seeds of the achiote tree (Bixa orellana), native to tropical parts of the Americas.

Vegan colour, not always vegan food

The colour itself is a plant seed extract and is vegan. Worth remembering, though, that annatto often colours foods that are not vegan, like cheddar and butter, so the colour passing the test does not mean the product does.
