E479b Thermally oxidised soya bean oil with mono- and diglycerides: Halal or Haram?
Doubtful
An anti-sticking emulsifier. E479b (Thermally oxidised soya bean oil with mono- and diglycerides) is doubtful.
Plant oil or animal fat: the label does not say which
Why it is doubtful
It contains mono- and diglycerides, so the E471 question comes with it.
Halal or not depends on what it is made from
E479b is Mushbooh: Halal when its mono- and diglycerides come from plants or a Halal source, not when they come from pork.

Scholarly view
Schools of law
Hanafi · Maliki · Shafi'i · HanbaliA fatty acid from plant oil, from synthesis, or from an animal slaughtered the Islamic way (zabiha) is Halal in every school. From pig fat, or from an animal not slaughtered that way, it is not. The schools differ on one point only: where a forbidden fat has been chemically changed into a new substance (istihala), Hanafi and Maliki accept it, while Shafi'i and Hanbali do not. E479b starts from soya oil, but the mono- and diglycerides it is reacted with carry the same question as E471. The tartaric acid in E483 follows the tartrate ruling: made chemically or from unfermented grapes it is Halal by agreement; from wine sediment, Hanafi and Maliki accept it as a changed substance, while Shafi'i and Hanbali are more cautious. If the label does not say where the fatty acid came from, all four advise caution.
Depends on source
Certification bodies
Dept. of Islamic Development Malaysia / Halal Food Authority, UKNeither body publishes a ruling on these E-codes; both certify whole products. The Halal Food Authority assesses each additive by its source (animal, plant or synthetic), its processing aids and any alcohol, so these are cleared only when the fatty acid comes from plants or a Halal source and, for E483, the tartaric acid is not from wine.JAKIM — Halal Malaysia Portal ↗HFA FAQ ↗
SANHA (E304)Lists ascorbyl palmitate as Halal, made from a synthetic chemical.SANHA — E304 ↗

Darul Uloom Trinidad & TobagoLists E470 (the sodium, potassium and calcium salts), E470b, E477, E479b and E483 among E-numbers that are not necessarily haram but may come from animal or plant sources, so they must be checked.Darul Uloom Trinidad & Tobago — E-numbers ↗
Look for a product that names the source, says plant-based or vegan, or carries a Halal certificate. If nothing on the packet settles it, the manufacturer can tell you, and their answer is the only thing that turns E479b from a question into an answer.
A status here describes the additive in general, and a specific product can be different. The same number can be made from plant or animal material depending on the manufacturer, and the label does not say which.

An additive's status describes the additive in general. What matters is the whole ingredient list on the packet in your hand.
This is information, not a fatwa. These statuses combine published scholarly positions with ingredient analysis, and they can be incomplete or out of date. For anything that matters, confirm with the manufacturer and with a qualified authority.
