Kosher, except for Pesach
Description: Triammonium citrate (acidity regulator)
Function: acidity regulator
Rationale:
Citrate is very commonly corn-derived in the US; OK Kosher/OU treat corn-based citric acid/citrates as kitniyot-shenishtaneh, warranting a Passover flag.
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.
