🌾 Wheat allergy: label names, hidden sources & scanning
Wheat allergy is an immune reaction to wheat proteins — related to but distinct from coeliac disease (see the gluten guide). Wheat is the backbone of industrial food production, appearing as flour, starch, and protein in places far beyond bread.
Hidden label names our scanner matches
An ingredient list can contain wheat 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 wheat commonly hides
- bread, pasta and pastry
- soups and sauces (thickener)
- processed meats
- soy sauce (most brands)
- beer
- candy and licorice
How Scallergy verdicts wheat
Avoid — wheat (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 wheat?
Beyond the word “wheat” itself, look for terms like semolina, durum, farina, bulgur, einkorn, emmer. These are the exact terms Scallergy's scanner matches when it checks an ingredient list.
Does wheat have to be declared on the label?
Yes — in the EU (Regulation 1169/2011, Annex II) and the US (FALCPA/FASTER Act) wheat must be emphasised in the ingredient list of prepacked food.
What does “may contain wheat” 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 wheat-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.
