Kosher, except for Pesach
Description: Lactic acid (preservative) (acid) (antioxidant)
Function: antioxidant
Rationale:
STAR-K: lactic acid is generally synthetic/pareve but may be corn-derived, so the resolution of the conflicting not_kosher+except_passover flags is except_passover (Passover-only kitniyot concern, not year-round non-kosher).
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.
