Does onion flavouring contain an allergen?
It depends on how it was made. Open Food Facts does not link onion flavouring to an allergen, and Bravoora’s label checker does not read the name as one. The label must name any allergen it carries.
Is onion flavouring vegan?
It depends on the make. Some kinds of onion flavouring 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.
