Is E1105 halal?
E1105 is generally considered halal. E1105 — Lysozyme — is used in food as preservative. E1105 can be of animal origin, but only from materials the halal rules themselves permit — the kind of source that carries no slaughter conditions. Strict vegetarians may still wish to avoid E1105, but as a halal matter no slaughter condition applies to this kind of source.

What is E1105?
Lysozyme. Preservative
Where does E1105 come from?
E1105 can be produced from either plant or animal raw materials, and the label almost never says which. The same E-number can come from a different source in another product, so where the origin matters, check that product's certification.
Sourcing and scholarly views on E1105
Additives like E1105 draw little scholarly controversy: an animal-derived material from a permitted source — milk, eggs, bees or similar — carries no slaughter requirement in any major school. The discussions that do arise concern derivation chains, such as whether an animal-origin enzyme or carrier touched production, which certification audits rather than ingredient lists can answer. Strict vegetarians apply their own stricter filter, which the vegetarian row above reflects.

What this is based on
The classification of E1105 rests on public records rather than opinion: the Open Food Facts taxonomy supplies the origin signal and the technological function, the UK Food Standards Agency register confirms authorisation status, and Commission Regulation (EU) No 231/2012 defines which raw materials it may legally be made from.
