Kosher all year around
Description: Sodium fumarate (acidity regulator)
Function: acidity regulator
Rationale:
Commercial fumaric acid is predominantly made via petrochemical isomerization of maleic acid (not fermentation), and fumarates carry no documented animal-derived or kitniyot concern in kosher literature.
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.
