Additive identity
Possible source pathways
The finished molecule can be identical across feedstocks. The Halal ruling follows the pathway, not the code alone.
- plant · Typical Halal The legal identity is soya bean oil reacted with mono- and diglycerides. Soya is plant. Food-grade TOSOM is specified on soya, not tallow.
TOSOM—thermally oxidised soya bean oil interacted with mono- and diglycerides—is E479b (Codex INS 479(b)). The legal identity names soya. That plant identity is Halal.[1][2]
It is still an emulsifier system. If the same margarine also lists unlabeled E471 or DATEM, those codes keep their own source questions. Soy allergy is separate from fiqh.
Where you'll find it
- Bakery fats and margarine
- Anti-spattering / crystal control
How to verify
1) Match E479b, INS 479(b), or TOSOM. 2) Treat the additive as soya-based Halal. 3) Still verify other glycerides in the shortening.
- E479b = TOSOM = soya-oil identity → Halal.
- Do not skip other glycerides on the same pack.
Conditions for Halal
- E479b / TOSOM as defined (soya oil reaction product) → Halal
- Finished bakery fat: still check E471/E472/E481 listed beside it
- Soy allergy is a health issue, not a Halal ban
Scholarly differences
Unlike unlabeled E471, E479b’s legal name includes soya bean oil. That is why this page’s headline is Halal for the additive itself. Do not extend that headline to a shortening that also lists unspecified E471.
