E numbers appear on almost every processed food label sold in the UK, EU, Malaysia, and the Gulf. For Muslim consumers and halal food manufacturers, understanding which E numbers are halal, which are haram, and which fall into a grey area is an essential part of halal compliance. This guide covers the full picture for 2026.
What Are E Numbers?
E numbers are codes assigned to food additives that have been approved for use in the European Union. The "E" stands for Europe. Each E number identifies a specific additive — a colouring, preservative, emulsifier, stabiliser, antioxidant, sweetener, or flavour enhancer — that has passed a formal safety assessment by the European Food Safety Authority (EFSA).
The E number system is used not only in EU member states but also in the UK (post-Brexit, retained via the UK Food Additives Regulations), Malaysia (under the Food Regulations 1985), the UAE (under ESMA standards), and many other markets. When a Malaysian food manufacturer exports to the EU, they use the same E number codes on their EU-facing labels. This shared nomenclature makes E number literacy universally useful for halal professionals.
E numbers are grouped into categories by function:
- E100–E199: Colours
- E200–E299: Preservatives
- E300–E399: Antioxidants and acidity regulators
- E400–E499: Thickeners, stabilisers, and emulsifiers
- E500–E599: pH regulators and anti-caking agents
- E600–E699: Flavour enhancers
- E700–E999: Miscellaneous (sweeteners, gases, waxes)
How to Read an Ingredient Label for E Numbers
Under EU and UK food labelling regulations, additives must be declared in the ingredients list by their function and either their E number or name — e.g. "colour (E120)" or "colour (carmine)". Both formats are legal, which means manufacturers can obscure animal-derived additives behind technical names.
Key label-reading tips:
- Scan for E numbers in the 400s — emulsifiers and stabilisers are the most common source of animal-derived additives (E441 gelatin, E471 mono- and diglycerides).
- Check colour declarations — E120 (carmine/cochineal) is the most important animal-derived colour to identify.
- Watch for name substitutions — "carmine", "cochineal extract", "carminic acid", "natural red 4" are all E120. "Gelatin" is E441. "Lard" may appear in bakery ingredients without an E number.
- Verify the source of E471 — mono- and diglycerides of fatty acids can be plant-derived (halal) or animal-derived (mashbooh/haram); the label will not specify unless the product is certified halal.
E Numbers That Are Definitely Halal
The following E numbers are derived from plant, mineral, or synthetic sources and are accepted as halal by major certification bodies including JAKIM, MUI, BPJPH, IFANCA, and HFA:
- E100 — Curcumin: Yellow pigment from turmeric root. 100% plant-derived. Widely used in dairy products, mustard, and confectionery. Halal.
- E101 — Riboflavin (Vitamin B2): Produced by fermentation or synthetically. Halal.
- E160a — Beta-carotene: Orange-yellow colour from carrots or synthetic production. Halal (confirm not derived from algae using animal-based media).
- E160c — Paprika extract / Capsanthin: Red-orange colour from paprika peppers. Halal.
- E162 — Beetroot red / Betanin: Deep red colour extracted from beetroot. Halal.
- E300 — Ascorbic acid (Vitamin C): Synthetic or derived from glucose fermentation. Halal.
- E330 — Citric acid: Produced by fermentation of sugars using Aspergillus niger. The fermentation medium is typically plant-based. Halal (JAKIM and MUI approved).
- E406 — Agar: Gelling agent from red seaweed. Halal.
- E407 — Carrageenan: Thickener/gelling agent from red algae. Halal.
- E440 — Pectin: Gelling agent from citrus peel and apple pomace. Halal.
- E500 — Sodium carbonates: Mineral-derived baking agent. Halal.
- E621 — Monosodium glutamate (MSG): Produced by bacterial fermentation of molasses or starch. Halal when produced using halal fermentation media (verify with manufacturer or certifier).
Doubtful (Mashbooh) E Numbers
These E numbers have ambiguous halal status because they can be derived from either plant/synthetic sources (halal) or animal sources (potentially haram), and standard labels do not disclose the origin:
- E471 — Mono- and diglycerides of fatty acids: One of the most common emulsifiers in processed food. Sourced from palm oil (halal) or animal fat (haram if from pork, mashbooh if from non-halal-slaughtered animals). Without halal certification, this is doubtful.
- E472a–e — Esters of mono- and diglycerides: Same sourcing ambiguity as E471. Frequently used in bread improvers, margarines, and cakes.
- E473 — Sucrose esters of fatty acids: Emulsifier from sucrose and fatty acids; fatty acid source may be animal.
- E476 — Polyglycerol polyricinoleate (PGPR): Derived from castor oil and glycerol; glycerol may be animal-derived. Common in chocolate to reduce viscosity.
- E322 — Lecithin: Usually soy-derived (halal) but can be egg-derived. Egg lecithin is halal (from permissible eggs), but confirm source.
- E920 — L-cysteine: Amino acid used as a flour improver (dough conditioner in bread). Historically sourced from human hair or duck feathers. Synthetic production is now common and halal. Feather-derived is considered halal by many scholars; human-hair derived is considered haram by most scholars. Require certification for commercial products.
- E631 — Disodium inosinate: Flavour enhancer produced from meat or sardines (haram/mashbooh) or by fermentation of sugars (halal). Label does not specify source.
- E635 — Disodium ribonucleotides: Blend of E631 and E627 with same sourcing ambiguity.
E Numbers That Are Definitely Haram
The following E numbers are derived from prohibited sources and are haram according to all major Islamic certification standards:
- E120 — Carmine / Cochineal / Carminic acid / Natural Red 4: Vivid red pigment from crushed female cochineal insects (Dactylopius coccus). Insects are categorically haram under the majority scholarly position. Found in: yoghurt, juice, confectionery, cosmetics, and some medications. One of the most common hidden haram ingredients in food.
- E441 — Gelatin: Gelling agent derived from animal bones and hides. The overwhelming majority of commercial gelatin is porcine-derived (from pig bones and skin). Bovine gelatin is permissible only if from halal-slaughtered cattle with verified documentation. Used in: jelly confectionery, marshmallows, dessert mixes, capsule shells.
- E542 — Bone phosphate / Edible bone phosphate: Anti-caking agent derived from animal bones. Likely from pork or non-halal-slaughtered animals in most supply chains. Used in: dried milk powder, some icing sugars.
- E904 — Shellac: Glazing agent secreted by the lac bug (Kerria lacca). Insect-derived; haram. Used as a coating on confectionery (some chocolate beans, apples in export markets), hard tablets, and wood finishes used on food-contact surfaces.

How to Get a Halal-Certified Product
For food manufacturers seeking halal certification, E number compliance is a core part of the certification audit. Here is what major certifiers require:
- Ingredient sourcing documentation: For every E number on your ingredient list that is potentially animal-derived (E471, E472, E441, E542, E120, E476, E920, E631), you must provide the supplier's halal certificate or a declaration of plant/synthetic origin.
- Supplier halal certificates: The certificate must be from an accredited certification body recognised by your target market's authority (e.g., JAKIM-recognised bodies for the Malaysian market; ESMA-recognised bodies for the UAE).
- Annual renewal: Ingredient sourcing documentation must be renewed annually, as supply chains change. A product that was halal-certified using plant-derived E471 in 2023 may need to re-verify if the supplier changes their fat source.
- Production facility audit: Beyond ingredients, the certifier audits for cross-contamination with pork or alcohol during processing, cleaning procedures, and staff training.
