You pick up a packet of biscuits. You see “E471” in the ingredient list. You put it down and wonder if you should worry. Later, you pick up something else, see “E330,” and wonder the same thing. The E-number system can feel like a secret language designed to hide what you are actually eating. Once you understand how the system works, most of that anxiety disappears — because the majority of E-numbers turn out to be harmless synthetic chemicals or plant extracts.
What Are E-Numbers, Exactly?
E-numbers are codes assigned by the European Union to substances that have been officially approved for use as food additives. The “E” stands for Europe (or European). Each code represents a specific additive that has passed safety assessment by the European Food Safety Authority (EFSA) and been approved for use in food manufacturing across EU countries. The UK retained these standards after leaving the EU.
Food additives are used for a range of practical purposes:
- Colours — make food look more appealing (E100–E180)
- Preservatives — extend shelf life by preventing microbial growth (E200–E285)
- Antioxidants — prevent fats from going rancid (E300–E321)
- Emulsifiers, stabilisers, thickeners — improve texture and consistency (E322–E495)
- Acidity regulators — control pH to affect flavour and preservation (E500–E585)
- Flavour enhancers — intensify natural flavours (E620–E640)
- Miscellaneous — sweeteners, glazing agents, propellants, anti-caking agents (E900+)
Having an E-number does not mean the additive is synthetic or industrial — turmeric’s active compound is E100 (curcumin), beetroot juice is E162, and vitamin C is E300 (ascorbic acid). Many E-numbers are familiar natural substances.
Why E-Numbers Matter for Muslim Consumers
The E-number system itself is neutral — it is simply a labelling system. The halal concern arises because some E-numbers can be produced from animal sources, and if that animal source is pork or an improperly slaughtered animal, the additive is haram.
The word “can be” is important. Many E-codes that have the potential to be animal-derived are actually produced synthetically or from plant sources by the vast majority of manufacturers. The E-number alone does not tell you the source — it tells you what the additive is, but not where it came from in a particular product.
This is why halal checking requires knowing which E-codes have animal source potential, then either:
- Looking for vegan/vegetarian labelling that confirms plant sourcing
- Contacting the manufacturer directly
- Looking for a halal certification logo
The E-Number Range System: A Map
E100–E180: Food Colours
These additives give food its colour. Most are synthetic dyes or plant extracts. The halal concern in this range is concentrated in one place:
E120 (Carmine) — derived from crushed cochineal insects. This is the most important haram additive to know. It gives products a red/pink colour and is found in strawberry yoghurts, fruit drinks, some sauces, and processed meats. Avoid any product listing E120, carmine, cochineal, or “natural red” without a halal certification.
Everything else in the E100–E180 range is either synthetic (E102, E110, E122–E133, E142, E151) or from plant sources (E100 turmeric, E160a beta-carotene, E160b annatto, E162 beetroot red, E163 anthocyanins). No halal concerns.
E200–E285: Preservatives
These prevent bacterial and fungal growth. The entire range is synthetic. Common ones you will see:
- E200/E202 — sorbic acid and potassium sorbate (in dairy, bread, fruit products)
- E210–E213 — benzoic acid and benzoates (in soft drinks)
- E220–E228 — sulphites (in dried fruit, wine — avoid wine regardless)
- E260–E263 — acetic acid and acetates (the vinegar family; halal)
- E270 — lactic acid (from fermentation; halal)
No halal concerns in this range beyond the standard alcohol-in-wine concern.
E300–E321: Antioxidants
These prevent oxidative rancidity (fats going off). Mostly synthetic vitamins and phenolic compounds.
- E300 — Ascorbic acid (Vitamin C) — halal
- E306–E309 — Tocopherols (Vitamin E) — from plant oils; halal
- E320 — BHA, E321 — BHT — synthetic; halal
No significant halal concerns in this range.
E322–E495: Emulsifiers, Stabilisers, Thickeners, Gelling Agents
This is where the main halal checking is required. This range includes E441 (gelatine) and E471 (mono and diglycerides), which are the two most commonly encountered halal concerns in packaged food after E120.
E441 — Gelatine: Almost always porcine (from pig skin and bones) without a halal certification. Appears in gummy sweets, marshmallows, some yoghurts, some ice cream, some medications. Haram without halal cert.
E471 — Mono and diglycerides of fatty acids: May be from plant oils (halal) or from animal fat including pork (haram). This is the most common emulsifier in processed food — it appears in bread, biscuits, margarine, ice cream, ready meals. If the product is labelled vegan, E471 is plant-derived. Otherwise, treat as mushbooh.
E400–E440 (Seaweed-based and plant gums): Carrageenan (E407), guar gum (E412), xanthan gum (E415), pectin (E440) are all from plant or microbial sources. No halal concerns.
E422 — Glycerol: Can be from animal fat or plant oils. Often synthetic. If vegan-labelled, plant-derived. Otherwise mushbooh.
E470–E477 — Fatty acid derivatives: Various emulsifiers derived from fatty acids that may be animal-derived. As a group, these warrant vegan label checking. If not vegan-labelled, they are mushbooh.
E500–E585: Acidity Regulators, Anti-Caking Agents
Mostly mineral salts. Carbonates (E500–E504), phosphates (E338–E341, E450–E452), chlorides (E508, E509, E511), and similar. Generally halal.
Exception: E542 — Bone phosphate. Made from animal bones. Mushbooh if source is not confirmed (could be from non-halal slaughtered animals). Rare in retail food.
E620–E640: Flavour Enhancers
This range includes glutamates (E620–E625) and nucleotides:
E621 — Monosodium glutamate (MSG): Produced by fermentation; halal. A very common additive in Chinese cuisine, crisps, and savoury snacks. Not a halal concern.
E627 — Disodium guanylate: May be from pork, fish, or yeast/plant sources. Mushbooh. Often used alongside E631. Check for vegetarian labelling.
E631 — Disodium inosinate: As E627. Mushbooh. Check for vegetarian labelling.
E635 — Disodium ribonucleotides: A blend of E627 and E631. Same mushbooh concern.
Quick rule for this range: Vegetarian-labelled products use yeast-derived E627/E631. If not vegetarian-labelled, treat as mushbooh.
E900–E1521: Miscellaneous
This catch-all range includes:
E901 — Beeswax: From bees. Halal under majority scholarly position. E903 — Carnauba wax: From Brazilian palm; halal. E904 — Shellac: From lac beetle secretions. Haram (Hanafi position) or mushbooh (other schools). E920 — L-Cysteine: Dough conditioner from hog hair, duck feathers, or synthetic. Mushbooh/haram if from pork source.
Sweeteners (E950–E968): Almost all synthetic. Aspartame (E951), sucralose (E955), stevia (E960) — all halal.

How to Use This Knowledge in a Supermarket
Fastest approach (60 seconds):
- Glance for “gelatine” or “E441” — if present without halal cert, reject
- Glance for “carmine” or “E120” — if present, reject
- Glance for E471/E627/E631 — if present, check for vegan/vegetarian label
- If vegan label present → safe; if not → use HalalCodeCheck for the specific code
What to ignore: E100, E101, E102, E200–E260, E300–E340, E400–E440 (most), E500–E520, E621, E950–E968. These are synthetic or plant-derived. You will see them on many labels. They are not a concern.
