🍞 Gluten (cereals) allergy: label names, hidden sources & scanning
Gluten covers proteins in wheat, rye, barley, spelt and their hybrids. For people with coeliac disease even small amounts cause intestinal damage; others avoid it for non-coeliac sensitivity. "Wheat-free" does not automatically mean gluten-free — rye and barley count too.
Hidden label names our scanner matches
An ingredient list can contain gluten (cereals) without ever using the word. These are the actual terms Scallergy's matching engine checks — the same list the app uses when it scans a barcode:
Common derivatives
Where gluten (cereals) commonly hides

- beer and malt drinks
- soups and sauces (roux, thickeners)
- processed meats and sausages
- soy sauce (most brands)
- oats without a gluten-free label (cross-contact)
How Scallergy verdicts gluten (cereals)
Avoid — gluten (cereals) (or one of the label names above) appears in the product's ingredient list.
Caution — the product carries a “may contain” / cross-contamination warning for it.
Unknown — we don't have trustworthy ingredient data, and we say so instead of guessing. The verdict is always driven by what's in the product; the severity you set in your profile is shown as context.

Frequently asked questions
Which label names mean gluten (cereals)?
Beyond the word “gluten (cereals)” itself, look for terms like rye, barley, oats, spelt, triticale, malt. These are the exact terms Scallergy's scanner matches when it checks an ingredient list.
Does gluten (cereals) have to be declared on the label?
In the EU, yes — it is one of the 14 Annex II allergens (Regulation 1169/2011) and must be emphasised in the ingredient list. In the US it is not one of the FDA's 9 major allergens, so labelling is less strict — read ingredient lists carefully on imported products.
What does “may contain gluten (cereals)” mean?
“May contain” is a voluntary cross-contamination warning: the product doesn't list it as an ingredient, but it is made where contact is possible. Scallergy shows these as a Caution verdict — distinct from Avoid, which means the allergen is actually in the ingredient list.
Can Scallergy guarantee a product is gluten (cereals)-free?
No — no app can. Scallergy checks ingredient data from USDA FoodData Central, Open Food Facts, and community submissions, shows its source and an honest “Unknown” when data is thin, and is assistive only: always check the printed label and follow your allergist's advice.
