Is E621 halal?
E621 is generally considered halal. E621 — Monosodium glutamate (MSG) — is used in food as flavour enhancer. The assessment is straightforward here: E621 is produced from plant or mineral raw materials, a category Islamic dietary law accepts in food. That holds regardless of brand, so a product is not made doubtful by containing E621 alone.
Automated classification, not a religious ruling. No scholar or certification body has reviewed this assessment — always check the product's own halal certification.
What is E621?
Monosodium glutamate (MSG). Flavour enhancer
Where does E621 come from?
E621 is obtained from plant, mineral or synthetic sources, so it raises no animal-derivation concern on its own.
Sourcing and scholarly views on E621
There is no significant scholarly disagreement over additives like E621. Substances of plant, mineral or synthetic origin are permissible across the schools of Islamic law, under the principle that foods are permitted unless specifically prohibited — the position the European Council for Fatwa and Research applies to plant-derived and synthetic E-numbers. The practical question scholars do raise is cross-contamination during manufacturing, which is a matter for product certification rather than for the additive itself.
The persistent rumour that MSG hides a pork derivative is unfounded: E621 is produced by bacterial fermentation of plant sugars — molasses, sugar cane, starch — and fatwa collections treat it as permissible. Indonesia's MUI, the world's largest certifier of MSG plants, certifies it while auditing the fermentation nutrients, the one step where an animal-derived input could theoretically appear. The scholarly debates around MSG concern health, not halal status.

What this is based on
The classification of E621 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.
