A sugar substitute, or artificial sweetener, is a
food additive which attempts to duplicate the effect of
sugar or
corn syrup in
taste, but usually with less
food energy. An important class of sugar substitutes are known as high intensity sweeteners. These are compounds where sweetness is many times that of
sucrose; accordingly, much less sweetener is required and energy contribution often negligible. The sensation of sweetness caused by these compounds (the "sweetness profile") is sometimes notably different from sucrose, so they are used in complex mixtures that achieve the most natural sweet sensation.
