Kosher, except for Pesach
Description: Annatto, bixin, norbixin (food colouring)
Function: food colouring
Rationale:
The achiote seed itself is not kitniyot, but commercial annatto color extracts are commonly suspended in oil or stabilized with dextrin/maltodextrin carriers that can be chametz/kitniyot-derived; kept unchanged pending stronger sourcing.
If you don't see a status above, it does not mean the additive is not kosher automatically - it might just not be documented in our database yet.
