Does rye sourdough powder contain an allergen?

Yes. Rye sourdough powder is made from a cereal containing gluten: labels in the UK, Europe and the Gulf must declare it. In the US it is not a listed allergen, because US labels name wheat only.

An allergen is stated only when two of three checks agree: the Open Food Facts record, Bravoora’s label checker, and the ingredient’s own name or family (oat flour is oats, a cheese is milk). Every name where they disagree waits for a person to review it.
