Hidden pork ingredients: the label names to watch for
Nobody labels an ingredient "pork fat". They label it E471, stearate, or shortening. This is the translation.
Pork derivatives appear on labels as: gelatine / E441, lard, tallow, E471 and E472, E570 stearic acid, E422 glycerol, E542 bone phosphate, E920 L-cysteine, pepsin, lipase, collagen, keratin, heparin and "natural flavouring". Most of these can be plant-derived instead, which is why they are Mushbooh rather than automatically haram.
The fourteen names
| # | Label name | What it is | Found in |
|---|---|---|---|
| 1 | Gelatine / gelatin / E441 | Collagen from skin and bone; pork is the largest global source | Sweets, yoghurt, mousse, capsules, cereals |
| 2 | Lard | Rendered pork fat, named plainly | Pastry, refried beans, traditional baking |
| 3 | Tallow | Rendered animal fat, usually beef but not always | Fried foods, pastry, some crisps |
| 4 | E471, E472a–f | Emulsifiers from fatty acids, plant or animal | Bread, ice cream, margarine, biscuits |
| 5 | E570 stearic acid / E572 magnesium stearate | Fatty acid, plant or tallow | Supplements, confectionery coatings |
| 6 | E422 glycerol / glycerine | From fat splitting, plant or animal | Soft sweets, icing, low-fat spreads |
| 7 | E542 bone phosphate | Ground animal bone | Anti-caking agent, supplements |
| 8 | E920 L-cysteine | Amino acid; can be from hair, feathers or synthesis | Bread, buns, pizza bases |
| 9 | Pepsin | Digestive enzyme, commonly porcine | Cheese, protein hydrolysates |
| 10 | Lipase | Fat-splitting enzyme, often animal | Cheese, bread improvers, flavour |
| 11 | Collagen / hydrolysed collagen | Gelatin under a different name | Supplements, drinks, sausage casings |
| 12 | Keratin | Protein from hooves, horn, hair, feathers | Supplements, some processed foods |
| 13 | Heparin / chondroitin | From intestinal mucosa and cartilage | Supplements |
| 14 | "Natural flavouring" | Legally vague; can include animal-derived components | Almost everything savoury and sweet |
The key distinction: haram versus doubtful
Most items on this list are not automatically pork. Numbers 4, 5, 6, 8, 10 and 14 can perfectly well be plant-derived, and in Western Europe usually are, because plant feedstocks are cheaper at industrial scale. That is why they are classified Mushbooh rather than haram.
The ones that are hard stops when present and unqualified: lard (named plainly), E542 (bone), and gelatine where porcine or unspecified.
Names that sound suspicious but are fine
These matter too, because worrying about the wrong things has its own cost:
- Lactic acid (E270), lactates (E325–327). From fermentation, not dairy and not animal, despite the name
- Lactose. A milk sugar; dairy, and halal
- Cream of tartar (E336). A by-product of winemaking, but a mineral salt with no alcohol; generally accepted as halal
- Citric acid (E330). Fermentation-produced, halal. The widely circulated claim otherwise is false
- Vegetable glycerine. Explicitly plant-derived
- Vitamin B12. Bacterial fermentation, halal
- Rennet labelled microbial or vegetarian. Non-animal
- MSG (E621). Bacterial fermentation of plant sugars, halal
How to check quickly
- Scan the barcode. The app checks all fourteen names automatically.
- Look for a vegetarian or vegan mark. This resolves items 1–13 in a single glance, since none may be animal-derived in a vegetarian-certified product.
- Read the tail of the ingredient list. These items appear at the end, in small quantities.
- For staples, ask the manufacturer once. A specific question about a specific additive gets a specific answer.

Frequently asked questions
What is the most common hidden pork ingredient?
Gelatin, because it appears in products people do not associate with meat: sweets, yoghurts, mousse desserts, vitamin capsules and the vitamin D coating on some breakfast cereals. Pork skin is the largest single raw material for gelatin worldwide.
Does E471 always mean pork?
No. E471 is made from fatty acids that can come from plant oils such as palm or rapeseed, or from animal fat. In Western Europe plant sources dominate on cost grounds. The label does not state which, which is why it is classified as doubtful rather than prohibited.
Does a vegetarian label rule out all of these?
For animal-derived ingredients, yes. A vegetarian claim is legally meaningful and none of the animal-sourced items on this list may be present. It does not address alcohol in flavourings, and it says nothing about slaughter method for products that do contain meat.
