Is E920 Halal or Haram? L-Cysteine: Source Checks
Supplier verification neededThe ingredient code alone does not settle the halal status of your product. No certificate covering every supplier or batch is stored here.
Ingredient identity
E920 - l-cysteine
Catalogue category: flour treatment agent. Previously catalogued origin: animal/synthetic. This is background, not a declaration from your supplier.
Identifier matched to Open Food Facts’ collaborative taxonomy on 23 September 2026. This checks a name/code association, not current legal authorisation or religious approval.
Source and scope
L-cysteine identifies the amino acid, not a confirmed raw-material source for a specific supplier. Obtain the manufacturing-source declaration and certificate; historical production methods cannot identify the source of the product in your hand.
Reviewed 2026-09-23. Ingredient background or food-law information only; not halal certification of a finished product.
What to check on the actual product
- Ask the manufacturer for the source material and any processing aids or carriers.
- Match the certificate to the exact product, supplier and market.
- Check its validity dates and the certifier’s requirements.
For current EU food-use rules, consult the European Commission additive database. Regulatory approval and halal certification answer different questions.
Does “not certified” mean haram?
No conclusion follows from the absence of a certificate alone. It identifies a limit in the evidence available here. Ask the manufacturer and the qualified authority you follow.
