Thaumatin is a low-calorie protein sweetener and flavor modifier extracted from Katemfe, the fruit of the West African plant Thaumatococcus daniellii, and is totally natural with an intense sweetness. The protein is used primarily for its flavor-modifying properties and not exclusively as a sweetener. Thaumatin is cultivated in the rainforests of West Africa. It is an odorless, water soluble protein which possesses high heat stability Thaumatin I and Thaumatin II are the two main forms of protein present in the Katemfe plant. It is extensively used as a flavor enhancer instead of a sweetener and it does not contribute to major calories in the diet.
