Halal food scanner
PlatePal is a free halal food scanner. Scan a product barcode and it checks the ingredients against a halal profile and against your allergies at the same time, then shows one clear verdict. It is a screening tool that flags ingredients worth reviewing. It is not a halal certification and not a religious ruling.
How it works
- Scan the barcode. The camera detects it automatically, with no shutter button.
- Search by name if the barcode is damaged, missing, or unrecognised.
- Snap the ingredients label. PlatePal reads the text on your device when a product has no data on file.
You can also start in a browser with the halal food checker, then install the app when you want to scan in the aisle.
The ingredients that decide a halal verdict
Very little packaged food is obviously not halal. Pork and alcohol are easy to spot and rarely the real problem. What actually decides most verdicts is a short list of processing ingredients that can be made from either a plant or an animal, where the label gives you the name but not the origin.
| Ingredient | Why it matters |
|---|---|
| Gelatin (E441) | Made from pork hide, bovine hide or bone, or fish skin. The label almost never says which. Porcine gelatin is not permissible, and bovine gelatin depends on the slaughter. |
| L-cysteine (E920) | A dough conditioner in commercial bread and buns. Can be synthetic, fermented, or extracted from feathers or human hair. Only the first two are straightforwardly acceptable. |
| Mono- and diglycerides (E471) | Emulsifiers built from plant oil or from animal fat such as tallow or lard. Chemically identical either way. |
| Rennet and enzymes | Cheese coagulants. Microbial and fermentation-produced chymosin are generally accepted. Animal rennet depends on the source, and labels often say only Enzymes. |
| Carmine (E120) | A red colour from cochineal insects. Rulings on insect-derived ingredients differ between authorities, so many observant shoppers avoid it. |
PlatePal also screens for pork and its derivatives, ethanol added as an ingredient, and animal-derived additives including some glycerin, shellac, and stearates. Every entry links through to the ingredient guide so you can see the reasoning rather than just the outcome.
Certification marks
Where product data records a halal certification mark, PlatePal surfaces it and raises the verdict to Certified. A mark from a recognised certifier resolves the source questions above in a way an ingredient list cannot, because the certifier has seen the supply chain and you have not.
Certification bodies differ in their standards, and a mark accepted by one community may not satisfy another. PlatePal shows you which mark was found. It does not rank certifiers or decide which ones you should accept.
A worked example
Suppose you keep a halal profile and you also avoid milk. You scan a packaged chocolate biscuit. The ingredient list includes whey, mono- and diglycerides, and no certification mark.
- Allergen check: whey is milk, so this fails your allergen requirement outright. That alone settles it.
- Halal check: the emulsifier source is undisclosed, so the halal question is unresolved rather than failed.
- Combined verdict: PlatePal shows the allergen result first, because a confirmed allergen outranks an open question.
This is what stacking means in practice. Two separate requirements are evaluated on one scan, and the strictest applicable result is what you see. You are never asked to reconcile two different apps yourself.
What PlatePal cannot determine
Known limits
- Whether an animal was slaughtered according to halal requirements, when no certification is recorded.
- The origin of an ingredient that the manufacturer declares only by category, such as Enzymes, Natural flavouring, or Emulsifier.
- Cross-contamination from shared production lines, which is a manufacturing fact rather than an ingredient fact.
- Whether a recipe changed after the product data was recorded.
- Which school of thought or certifying authority you personally follow.
When any of these apply, PlatePal returns Insufficient data instead of guessing. A scan that admits uncertainty is more useful than one that invents confidence.
Honest about certainty
Every verdict shows what it rests on: Certified, Likely OK, Concerns found, or Insufficient data. Because this is a screening tool, verify certification with your own authority when it truly matters. PlatePal is designed to narrow the shelf down to what is worth a closer look, not to end the conversation.
Allergen alerts stay free
All allergen and gluten detection is free for everyone and is never placed behind the paywall. See the allergen scanner for what that covers. Premium adds profile stacking for households, unlimited scans, and compliant-alternative suggestions. It never adds safety.
Private by default
No account is needed to start, and PlatePal runs no advertising trackers. Signed out, your profiles and allergens stay on your device. Read the privacy policy for exactly what syncs when you do sign in.
