Kosher, except for Pesach
Description: Calcium gluconate (firming agent)
Function: firming agent
Rationale:
Gluconic acid is industrially produced by fermenting corn-derived glucose, so despite being highly processed, conservative kosher-for-Passover guides treat it as a kitniyot-derived ingredient requiring special certification.
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.
