Is E539 halal?
The halal status of E539 is not clearly established. E539 — Sodium thiosulphate — is used in food as antioxidant, sequestrant. We hold no verified origin or production evidence for E539, and an honest answer states that rather than guessing. A product-specific halal certificate, or the manufacturer confirming the raw material behind its E539, is what would settle it either way.
Automated classification, not a religious ruling. No scholar or certification body has reviewed this assessment — always check the product's own halal certification.

Sourcing and scholarly views on E539
Where the origin of an additive like E539 is undocumented, scholarly guidance splits along familiar lines. The juristic default, restated in the Islamweb fatwas cited below, is that food remains permissible on mere doubt — suspicion alone does not create a prohibition. Certification bodies take the operational opposite: they will not certify what they cannot audit. This site reports the data gap honestly rather than borrowing either presumption as a verdict.

What this is based on
The classification of E539 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.
