Is Mono- and diglycerides (E471) vegan?
Depends — this emulsifier can be made from plant oils or animal fat.
Also listed as: E471, glyceryl monostearate
Key facts
- Verdict
- Depends on the brand
- Category
- Additive
- Also listed as
- E471, glyceryl monostearate

- Sunflower lecithin products
Why
E471 is produced from glycerol and fatty acids. Most modern supply is palm or soy derived, but tallow is still used in some regions and the label does not say which.
What to check on the label
- E471 in bread, ice cream, margarine
- Vegan certification on the pack
- Region — tallow use varies by country

What is actually in it
Mono- and diglycerides of fatty acids (E471) are the world's most common food emulsifiers — they keep oil and water mixed in margarine, ice cream, bread, cakes, peanut butter, coffee whiteners and whipped toppings. Chemically they are glycerol bonded to one or two fatty acids, and those fatty acids can come from any fat: soybean, palm, rapeseed or sunflower oil — or beef tallow, lard or other animal fats. The finished molecule is identical either way, and labelling laws almost never require the source to be declared, which makes E471 one of the most ambiguous entries on an ingredient list. In practice, the great majority of global supply is plant-derived because vegetable oils are cheaper and suit more markets, but 'majority' is not 'all', and some regional products — particularly baked goods and margarines — still use animal-derived stock. The reliable signals are a vegan or vegetarian trademark, a manufacturer's written confirmation, or an ingredient list that says 'vegetable mono- and diglycerides'. Related emulsifiers share the same ambiguity: E472a–f (esters of mono- and diglycerides), E477 (propane-1,2-diol esters of fatty acids) and E481/482 (stearoyl lactylates) can all be made from either plant or animal fat. Glycerol (E422) and lecithin have the same source question. When a product matters to you, a quick email to the producer usually settles it — most keep source statements for exactly this question.

- Plant or animal — label does not say
- E472a–f — Esters of mono-/diglycerides

- E481 / E482 — Stearoyl lactylates
- Plant or animal
Questions people ask
Is E471 always animal?
No. Most is plant-derived today, but the code covers both sources.
What about E472?
Same ambiguity — the E472 family is built from the same fatty acids.
Are mono- and diglycerides usually vegan?
Most global supply is made from vegetable oils, so the odds favour plant origin — but animal fat is legally possible and undisclosed, so only a certification or manufacturer statement gives certainty.
Why are they in so many foods?
They are cheap, safe and extremely effective at keeping fat and water mixed, extending shelf life and improving crumb softness in bread.
Does 'vegetable emulsifier' on a label settle it?
Yes — if the source is stated as vegetable or plant, E471 is vegan. The problem is only with unspecified sources.
Is E471 halal or kosher?
It depends on the fat source, which is why halal- and kosher-certified products use documented plant or permitted animal sources. The same documentation answers the vegan question.
