Food label with "no pork" claim — but 8 other haram ingredients to check

"No Pork" Doesn't Mean Halal: 8 Other Ingredients to Check (2026)

9 min read

A packet of Haribo Starmix sitting next to a “no pork” badge. A strawberry yogurt labelled “suitable for vegetarians.” A sliced white loaf with no meat ingredient in sight. Each of these products has at some point contained an ingredient that mainstream Islamic scholars consider haram — and not one of those ingredients was pork.

“No pork” is the single most common halal misconception in the UK Muslim community. A LinkedIn post we shared showing the full ingredient breakdown of Oreos — a product that has carried a “suitable for vegetarians” label — generated a 10.4% engagement rate because so many people were genuinely surprised. The surprise is understandable: we are taught from childhood to avoid pork, and many families stop their label-reading there. But the Quran prohibits more than pork: it prohibits blood, carrion, and anything slaughtered without Allah’s name — none of which has anything to do with the pig.

Below are the eight non-pork ingredients that most commonly slip through unnoticed, what they are, which products typically carry them, and exactly what to look for on the label.


1. Gelatin (E441) — The One Everyone Knows About But Still Misses

Gelatin is extracted by boiling animal bones, skin, and connective tissue. It can come from pigs, but it can also come from cattle, fish, or chicken. The key issue is not the species — it is whether the animal was slaughtered according to Islamic rites.

Bovine gelatin appears on labels as “beef gelatin,” “bovine gelatin,” or simply “gelatin (bovine).” Without an HMC, HFA, or equivalent certification stamp on the pack, there is no guarantee the cattle were slaughtered correctly. The same applies to porcine gelatin, which is unambiguously haram regardless of certification.

Where you’ll find it: gummy sweets (Haribo, Maynards Bassetts), marshmallows, jelly desserts (Angel Delight, Bird’s Trifle), soft-gel vitamin capsules, some yogurts (certain Müller corner formats), panna cotta, and most supermarket cheesecakes.

Label tip: Search for the word “gelatine” (British spelling) or “gelatin” anywhere in the ingredients list. The E-code E441 is rarely used for gelatin in finished consumer products — manufacturers typically write it out in full — so you must scan the text, not just the E-number list.


2. Carmine / E120 — Beetles, Not Pork

Carmine (also listed as E120, cochineal, Natural Red 4, or carminic acid) is a vivid red dye produced by grinding dried cochineal beetles. It has no connection to pigs whatsoever — but it is derived from an insect, which makes it haram under the vast majority of Sunni scholarly opinion (Hanafi, Shafi’i, and Hanbali madhabs all prohibit consuming insects).

Where you’ll find it: red and pink yogurts (Müller Light Strawberry, Activia Raspberry), red-fruit juices, maraschino cherries, some flavoured waters, certain lipsticks and cosmetics, and a surprising number of supermarket own-brand red sweets.

Label tip: Look for “E120,” “carmine,” “cochineal,” or “carminic acid.” On food sold in the UK, any use of carmine must be declared under its name or E-number — it cannot hide under “colour.” Use the E-codes database to look up E120 for the full entry.


3. Shellac / E904 — The Invisible Glaze

Shellac is a resinous secretion produced by the lac insect (Kerria lacca), which is native to South and Southeast Asia. It is refined and sold as a glazing agent that gives sweets, chocolate, and apples a shiny finish. Like carmine, it is an insect-derived substance.

The scholarly position on shellac is more nuanced than on carmine. Some scholars consider it permissible because the resin is a secretion rather than the insect body itself; others rule it haram. It is widely classified as mushbooh — doubtful — by UK halal advisory bodies.

Where you’ll find it: chocolate-coated sweets (Smarties no longer use it, but many supermarket imitations do), some confectionery-coated nuts, certain pharmaceutical tablet coatings, and the shiny coating on apples sold in UK supermarkets.

Label tip: Look for “E904,” “shellac,” or “glazing agent (shellac).” The ingredient list must declare it by name or E-number under UK food law.


4. L-Cysteine / E920 — The Bread Improver Nobody Talks About

L-cysteine is an amino acid used as a dough conditioner and improving agent in commercial bread and baked goods. It makes dough easier to machine-process, reduces mixing time, and extends shelf life. The problem is its source: L-cysteine is commonly derived from human hair (collected primarily from Chinese hair salons and barbershops) or from duck and chicken feathers.

There is a synthetic (fermented) form of L-cysteine available, but manufacturers are not required to specify the source on the label — they simply write “E920” or “L-cysteine.”

Where you’ll find it: most mass-produced sliced white bread (Warburtons, Hovis, Kingsmill all use E920 or have done so in various product lines), burger buns, pizza bases, and many bakery items sold at fast-food chains.

Label tip: Search for “E920” or “L-cysteine” in the ingredients list. If you find it, contact the manufacturer to ask about the source — reputable halal-certified products will use synthetic or plant-based L-cysteine and will confirm this in writing.


5. Isinglass — The Hidden Fining Agent

Isinglass is a fining agent derived from the dried swim bladders of fish, typically sturgeon or other freshwater fish. It is used to clarify beer, wine, and sometimes fruit juices and ciders by binding to yeast and other particles and causing them to sink out of suspension.

The critical point: isinglass is used during processing and is largely removed from the final product. UK law does not always require its declaration on the label if it is not present in the final product as a functional ingredient — though fish allergen labelling rules mean it must be declared if traces remain. This makes it genuinely difficult to detect from the label alone.

Where you’ll find it: traditional real ales and cask-conditioned beers, many commercially produced wines, some apple ciders, and — less commonly — some cloudy fruit juices where manufacturers use it for clarity rather than taste.

Label tip: On alcoholic drinks, look for “may contain: fish” or “contains: isinglass” in the allergen information. On juice and cider, look for fish allergen warnings. When in doubt, choose products carrying the Vegetarian Society’s Vegan trademark, which prohibits isinglass use, or explicitly halal-certified beverages.


6. Natural Flavours — The Category That Covers Everything

“Natural flavours” or “natural flavouring” is one of the most permissive categories in food labelling law. Under UK regulations, a natural flavouring must be derived from a natural source — plant, animal, fungal, or microbial — but there is no requirement to specify which source.

This means “natural flavouring” can legally include:

  • Castoreum — a secretion from beaver anal glands, used as a vanilla or raspberry note in some products. Legal to use without declaration.
  • Animal-derived flavour carriers — ethanol (alcohol) used as a solvent to carry flavour compounds, even in savoury products like crisps and sauces.
  • Meat-derived Maillard reaction products — chicken fat or beef tallow-derived flavours used in “beef” or “chicken” flavour crisps.

Where you’ll find it: crisps and snacks (Walker’s Prawn Cocktail uses pork-derived flavour notes in some variants), flavoured coffee syrups, ready meals, and fruit-flavoured sweets.

Label tip: “Natural flavouring” is best treated as mushbooh by default unless the product carries halal certification or the manufacturer confirms the flavouring source in writing. This is not paranoia — it is a reasonable precaution given the opacity of the category.


7. Vanilla Extract — When Alcohol Is the Solvent

Pure vanilla extract is made by soaking vanilla beans in alcohol (typically ethyl alcohol) and water. The alcohol draws out the flavour compounds and remains in the finished extract, typically at a concentration of 35% ABV or higher. This is very different from vanilla flavouring, vanilla paste, or vanilla powder, most of which use no alcohol.

When vanilla extract is used as an ingredient in biscuits, ice cream, cakes, and flavoured yogurts, it carries this alcohol content into the finished product. The quantity is small, but the principle is the same: a product cannot be halal if it contains intentionally added alcohol.

Where you’ll find it: premium biscuits and shortbread, some ice creams (Häagen-Dazs uses real vanilla extract), artisan cakes, flavoured syrups, and protein shakes using “natural vanilla flavour.”

Label tip: The label will say “vanilla extract” (haram/mushbooh) rather than “vanilla flavouring” (typically alcohol-free) or “vanilla powder” (alcohol-free). Certified halal ice cream and biscuit brands use non-alcoholic vanilla flavouring instead.


8. Animal Rennet in Cheese — The Classic Overlooked One

Rennet is an enzyme used to coagulate milk during cheesemaking. Traditional animal rennet is extracted from the stomach lining of a newly slaughtered calf, lamb, or kid goat. The issue is that the animal from which rennet is extracted must be slaughtered according to halal rites for the rennet to be considered halal.

Most mass-market UK cheese uses microbial rennet (from fungi) or fermentation-produced chymosin (FPC) — both are halal. But traditional hard cheeses (Parmesan, Pecorino Romano, many artisan cheddars) and some premium soft cheeses still use animal rennet.

Where you’ll find it: Parmigiano-Reggiano (legally required to use animal rennet), Pecorino Romano, Grana Padano, some artisan British cheddars and Wensleydales, and certain imported French and Italian cheeses.

Label tip: Look for “rennet” or “animal rennet” in the ingredients or allergen information. “Vegetarian rennet,” “microbial rennet,” or “vegetarian cheese” indicates no animal rennet. If the label is ambiguous, contact the producer.

The 30-Second Label Scan Process

When you pick up a product and want a quick check, do this in order:

  1. Is there a recognised halal certification mark? HMC, HFA, or equivalent. If yes — you can stop here.
  2. Scan for “gelatine” or “gelatin” anywhere in the ingredients list.
  3. Scan for E120, “carmine,” or “cochineal” — these are haram regardless of source.
  4. Scan for E904 or “shellac” — flag as mushbooh.
  5. Scan for E920 or “L-cysteine” — flag as mushbooh pending source confirmation.
  6. Scan for “natural flavour(s)” or “natural flavouring” — flag as mushbooh without certification.
  7. If it’s cheese: look for “animal rennet” — flag as mushbooh.
  8. If it’s a sweet or baked product: check for “vanilla extract” vs “vanilla flavouring.”

This process takes under 30 seconds once practiced and will catch the overwhelming majority of problematic ingredients.


How we reached this verdict

The rulings in this article draw from:

  • Al-Mawsuah al-Fiqhiyyah al-Kuwaitiyyah (Kuwaiti Encyclopaedia of Islamic Jurisprudence) — primary reference for classification of food substances.
  • IFANCA (Islamic Food and Nutrition Council of America) — published guidance on gelatin, L-cysteine, and natural flavours.
  • HMC UK (Halal Monitoring Committee) — published E-number guidance and approved ingredient lists.
  • HFA UK (Halal Food Authority) — E-number classification database and position statements on carmine and shellac.
  • UK Food Standards Agency (FSA) — labelling obligations for allergens and additives under UK retained food law (assimilated from EU Regulation 1169/2011).
  • Manufacturer correspondence — we have contacted Warburtons, Kingsmill, and Müller directly to confirm sourcing of E920 and E120 respectively.

We update this article when certifying bodies publish revised positions.


Madhab note

The default position throughout this article follows mainstream Sunni Hanafi fiqh, which is the most widely followed madhab in the UK Muslim community. Notable divergences:

  • Shellac (E904): The Maliki madhab has historically been more permissive on insect-derived products used in small quantities; some Maliki scholars permit shellac as it is a secretion rather than the insect body. Hanafi, Shafi’i, and Hanbali positions lean toward prohibiting it.
  • L-Cysteine from feathers: Some scholars distinguish between hair/feathers from permissible animals slaughtered correctly (halal) vs. impermissibly sourced. Given that source confirmation is rarely available in commercial contexts, we default to mushbooh.
  • Alcohol in vanilla extract: All four madhabs agree that intentional addition of khamr (wine/beer) is prohibited. The status of ethyl alcohol from non-grape/date sources is disputed; some contemporary Hanafi scholars extend the prohibition, others do not. We classify vanilla extract as mushbooh given this dispute and advise seeking halal-certified alternatives.
