Such ingredients are useful for preparing flavouring compositions and a wide variety of flavoured foodstuffs to which they impart greater creaminess and bulkiness so that they have heightened effect in the mouth and generally an enhanced mouthfeel. They are also useful for enhancing the sweetness of foods sweetened with natural or artificial sweeteners, and giving it a more natural character.
