Kosher all year around
Description: Matrc acid (acid) (acidity regulator)
Function: acidity regulator
Rationale:
Commercial DL-malic acid is predominantly produced petrochemically (hydration of maleic anhydride from benzene/butane), not by corn fermentation, so no inherent kitniyot concern.
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.
