Is E920 halal?
E920 is haram (forbidden). E920 — L-cysteine — is a food additive. The doubt comes from manufacturing reality: producers make E920 from either vegetable or animal raw materials, and ingredient labels do not say which was used. A product whose E920 comes from the plant-based form is fine, and once a certifier has verified the source the doubt disappears.

What is E920?
L-cysteine. Improving agent
Where does E920 come from?
E920 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 E920
Scholarly treatment of source-ambiguous additives like E920 genuinely differs. The cautious position — followed by most certification bodies and by this site — treats an unverifiable origin as doubtful and points readers to certified products. The permissive position, stated in Islamweb's rulings on E-numbered additives, applies the principle that food is presumed permissible until a prohibition is established, so the mere possibility of an animal source does not make a product forbidden.
E920 carries a dispute unique among additives: its historical raw material was human hair, and scholars prohibit using any part of the human body in food — a point on which schools do not disagree. L-cysteine from duck feathers replaces the human-origin question with an ordinary slaughter question, while synthetic and fermentation-produced L-cysteine raises no objection at all. Certification therefore turns entirely on which of the three processes the supplier runs.

How this verdict was reached
E920 can be made from either plant or animal raw materials, and manufacturers rarely declare which. That unresolved origin is what makes it doubtful rather than permitted.

What this is based on
The classification of E920 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.
