Does onion oil contain an allergen?
Onion oil is not one of the allergens that food labels must declare in the US, the UK, Europe or the Gulf. Open Food Facts does not link it to an allergen, and Bravoora’s label checker does not read the name as one.
Is onion oil vegan?
It depends on the make. Some kinds of onion oil are made with an animal product and a label rarely says which, so a vegan profile gets Heads up. Whether it is vegetarian depends on the make too.
A pack can differ from the usual recipe: the app reads the label in your hand.

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.
