A sweetener is a substance added to food or drink to impart the flavor of sweetness, either because it contains a type of sugar, or because it contains a sweet-tasting sugar substitute.
Various natural non-sugar sweeteners and artificial sweeteners are used to produce food and drink.
Many artificial sweeteners have been invented and are now used in commercially produced food and drink.
Natural non-sugar sweeteners also exist,[1] such as glycyrrhizin found in liquorice.
