Is E415 Kosher?

Kosher, except for Pesach


Description: Xanthan gum (thickener) (stabitrser)

Function: stabitrser

Rationale: Xanthan gum is a fermentation product grown on a glucose substrate that can be wheat- or corn-derived; as of 2026 several major hashgachos (Eidah Hachareidis, Beis Din of Rav Landa, etc.) still dispute its Pesach permissibility despite other authorities (CRC, Matzav-reported letters) permitting it, so a Passover flag remains the cautious call.

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.
