To check food for allergens and additives quickly, photograph the ingredients list (not the front of the pack) with an ingredient scanner such as PureScan in CEMP Life. Super Intelligence (SI) reads the full list, expands compound ingredients, and flags allergens such as gluten, nuts, dairy, soy and sesame, plus high sugar and artificial additives, with a plain-language verdict in seconds. For severe allergies, always confirm against the packaging.
The 20-second allergen check
- Turn the pack over and find the ingredients list
- Photograph it in even light, without glare
- Add more photos to compare several products at once
- Read the concern and positive split, then the plain-language verdict
- Double-check anything marked "may contain" on the pack itself
Why are allergens so hard to spot on labels?
Because they rarely use the word you are looking for. Dairy appears as casein, whey or lactose. Gluten hides in malt, spelt or some modified starches. Soy turns up as lecithin. Compound ingredients, such as a "flavouring" or a sauce within a ready meal, have their own sub-lists. And "may contain" warnings sit in a different place from the ingredients.
An ingredient scanner fixes the translation problem: it reads every word, maps each one to known substances, and tells you what matters to you.
How to use PureScan step by step
- Open CEMP Life and choose PureScan in the Food and Nutrition pod.
- Tap the camera and photograph the ingredients label. You can add several photos to scan multiple products in one go.
- SI reads the label, including small and curved print, with no barcode or database required.
- You get a clear split of concerns (for example high sugar, artificial additives or allergens) and positives, plus a short verdict.
Scan any ingredients label before it goes in the basket.

Which additives should you look out for?
There is no single list that suits everyone, but people commonly want to know about:
- Sweeteners such as aspartame, sucralose and acesulfame K
- Colourings, especially synthetic azo dyes
- Preservatives such as nitrites in processed meat and benzoates in drinks
- Emulsifiers and thickeners in processed foods
- Added sugars split across several names (glucose syrup, dextrose, fructose) so none tops the list
PureScan names additives by what they are and what they do, rather than leaving you with an E number, so you can make your own decision.
How to check food for allergens when travelling
Labels abroad are where scanners earn their keep. Because SI reads the text itself, it is not defeated by a product that has never appeared in an English-language database. Photograph the label, and the scan returns a verdict you can read. CEMP Life works in English, Arabic, Spanish, German and French.
The limits, stated plainly
- Not a medical device. For a serious allergy, the label and the manufacturer remain the authority. Use a scan as a fast first check.
- Cross-contamination is invisible. A scan reads what is printed; it cannot see factory practices beyond the "may contain" statement.
- Recipes change. Scan the pack in your hand, not one you scanned last month.
