Bubblegum flavor is a combination of fruity flavors, usually a mix of esters that smell like fruit. The recipe differs from company to company, but the generic bubblegum flavor is usually made from a unique blend of esters. For example, it could be a "strawberry-banana-punch" mix, with more strawberry, raspberry, and blueberry esters added for extra berry flavor. Some natural bubble gum flavorings can be produced by combining banana, pineapple, cinnamon, cloves, and wintergreen. Vanilla, cherry, lemon, and orange oil have also been suggested as ingredients. Bubblegum flavor is not strictly a taste, but rather a smell. Manufacturers target our noses rather than our tongues when making artificial flavors, as our olfactory receptors in our nose can perceive around one trillion different scents.
