Not kosher
Description: Lysozyme (preservative)
Function: preservative
Rationale:
Lysozyme is extracted from hen egg white (a kosher source) but is used as an antimicrobial in cheese and wine production; commercial supplies are offered specifically as 'kosher certified' implying default/uncertified product requires reliable supervision, consistent with current flag; no authoritative source found declaring it kosher without 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.
