Is E471 halal? Mono- and diglycerides explained
Updated October 3, 2026 by Kamal Nasir
E471 is the code for mono- and diglycerides of fatty acids, an emulsifier that can be made from plant oils or from animal fats, including pork fat. Because the code does not say which, every certifier and scholar quoted below treats E471 as doubtful, or as something to check, when its source is not known, and several describe plant-derived E471 as halal. This page reports what those sources say. It is not a ruling, and you should ask your own scholar about anything that matters to you.
What E471 is
The UK's list of approved additives names E471 as "Mono- and diglycerides of fatty acids". The six numbers E472a to E472f are esters made from them, with acetic, lactic, citric or tartaric acid. In the United States, 21 CFR 184.1505 describes mono- and diglycerides as a mixture of glyceryl mono- and diesters, with minor amounts of triesters, prepared from fats, oils or fat-forming acids from edible sources, by reacting glycerin with fatty acids or with triglycerides.
They are used as emulsifiers and dough strengtheners. The American Halal Foundation lists ice cream, bread, margarine and chocolate as common uses, and names the possible sources as plant oils (palm, soybean, canola), beef tallow from cattle that may or may not have been slaughtered in a halal way, and pork fat. The same additive can come from any of these, and the number alone does not tell you which.
What halal certifiers and scholars say
- IFANCA, in its Halal Shopper's Guide, lists E-471 and "Mono & Diglycerides" under Investigate Further: its category for components used in small quantities that can contain subcomponents from haram animals, alcohol, or halal animals slaughtered by non-Muslims.
- The E-number sheet published by Halal Authority India (halalauthorityindia.com) gives E471 and E472 as "Mushbooh, Halal if it is from plant fat, Haraam if it is from pork fat".
- The American Halal Foundation (May 2025) says E471 can be halal when it comes from entirely plant-based oils or is produced synthetically, and is not halal if it comes from pork, from beef that is not zabiha, or shares equipment with non-halal fats.
- Sheikh Ahmad Kutty of the Islamic Institute of Toronto, answering on AboutIslam (September 2025), says E471 and E481 can be halal or haram depending on their source, and that when a label does not state the origin the ingredient is regarded as doubtful.
- Shaykh Sayeedur Rahman of Darul Ifta Birmingham, in an answer published on IslamQA.org, says E471 is typically made from soybean oil but can come from animals, that a plant source is halal, and that when the origin is unclear and not stated on the packaging it should be avoided, citing the hadith in Tirmidhi on leaving what causes doubt.
Where views can differ: transformation (istihalah)
Some scholars hold that complete chemical transformation (istihalah) can change the ruling of a substance made from an impure source; IslamQA.info answer 248124 applies that reasoning to L-cysteine (E920), for example. None of the E471 sources above apply it to E471: they treat the source as what decides the question. If istihalah matters to your practice, that is a question for your own scholar.
How to check a product that lists E471
- Read the label for a named source, such as "vegetable mono- and diglycerides", "plant based" or a specific oil. The American Halal Foundation recommends looking for exactly this wording.
- Look for a halal certification mark from a certifier you trust. A certified product answers the question for the whole product, including processing, which an ingredient list cannot.
- A vegetarian or vegan label tells you the emulsifier is not from animal fat, but it does not cover other questions such as alcohol in flavourings.
- Contact the manufacturer and ask where the E471 comes from, and whether the line is shared with animal fats.
- Check the related numbers too: IFANCA also lists E-470a, E-472a through E-472f, E-481 and E-491 under Investigate Further.
Looking it up while you shop
Dalil, a halal ingredient scanner for iPhone, lets you type E471 or point the camera at an ingredient panel, and shows what published rulings say with a link to each source and to the regulation that defines the ingredient. It never says a product is halal or certified, because slaughter method and alcohol content are not printed on a label, and it works offline with no account.
Questions people ask
Is E471 haram?
The sources quoted here do not call E471 haram in itself. They say it is not halal when made from pork fat, and several add fat from animals not slaughtered according to Islamic law. When the source is unknown, they treat it as doubtful.
Is E471 halal in ice cream or bread?
The food does not change the answer. What matters is where the E471 in that product came from, plus the rest of the ingredients. Check the label for a named plant source, look for a halal mark, or ask the manufacturer.
Is E471 vegan?
Not necessarily. It can be made from plant oils or from animal fat, so only a vegan label, a named plant source or the manufacturer can tell you.
