Where gluten hides: 12 names that aren't “wheat”

Avoiding gluten would be simple if it were always called gluten. The difficulty is that it travels under a dozen other names, several of which sound entirely unrelated to wheat.

The grains that are wheat under another name

  • Semolina, durum, farina — all wheat, all common in pasta and couscous.
  • Spelt, kamut, einkorn, emmer — ancient wheats, marketed as alternatives, still gluten.
  • Triticale — a wheat-rye hybrid.
  • Bulgur, freekeh, seitan — wheat products; seitan is essentially concentrated gluten.

The processed ingredients

IngredientWhere you meet it
Malt extract, malt vinegar, malted barleyBreakfast cereals, crisps, sauces, beer
Brewer's yeastSpreads, supplements, savoury flavourings
Soy sauceTraditionally brewed with wheat — tamari usually is not
Modified starchSource often unstated; in the EU it must be declared if from wheat
Hydrolysed vegetable proteinCan be wheat-derived
DextrinCan be wheat-derived; maltodextrin usually is not a concern

One piece of good newsIn the European Union, the fourteen major allergens — wheat included — must be highlighted in the ingredient list, typically in bold. So a wheat-derived starch cannot legally hide in an EU list. Outside the EU the rules differ, and the alternative names above matter much more.

The non-obvious products

These catch people out repeatedly, because nothing about them suggests bread:

  • Stock cubes and gravy — thickened with wheat flour more often than not.
  • Processed meats — sausages and burgers frequently use rusk or breadcrumb as a binder.
  • Chips in a shared fryer — the potato is fine; the oil that battered fish went through is not.
  • Crisps with seasoning — the seasoning can carry malt or wheat starch.
  • Some medications and supplements — wheat starch is a common excipient.
  • Communion wafers, play dough, some cosmetics — not food, still a route of exposure for coeliac disease.

Naturally gluten-free, and worth knowing

Rice, maize, quinoa, buckwheat (despite the name), millet, sorghum, amaranth, teff, and all pure oats certified gluten-free. Oats are the exception worth flagging: the grain itself contains no gluten, but it is very commonly contaminated in the field and at the mill, which is why "gluten-free oats" is a distinct product.

The limit of any label readingCross-contamination is invisible on an ingredient list. A product whose ingredients are all gluten-free may still be made on a line that handles wheat, and only a voluntary "may contain" warning would tell you. If you have coeliac disease, certified gluten-free labelling and the manufacturer remain the authority — no scanner, including ours, can see inside a factory.

A faster way to read

  1. In the EU, look for the bolded allergens first — it is the quickest scan.
  2. Learn the six processed names in the table; they cover most surprises.
  3. Treat "modified starch", "dextrin" and "hydrolysed vegetable protein" as questions outside the EU.
  4. For coeliac disease, prefer certified gluten-free over reasoning from a list.
