Thaumatin

Product name: Thaumatin
Application:
 Thaumatin is a low-calorie (virtually calorie-free) protein sweetener and flavour modifier. The substance is often used primarily for its flavour modifying properties and not exclusively as a sweetener.
Product Description:
 The thaumatins were first found as a mixture of proteins isolated from the katemfe fruit (Thaumatococcus daniellii Bennett) of west Africa. Some of the proteins in the thaumatin family (Simple Modular Architecture Research Tool accession #SM00205) are natural sweeteners roughly 2000 times more potent than sugar. Although very sweet, thaumatin's taste is markedly different from sugar's. The sweetness of thaumatin builds very slowly. Perception lasts a long time leaving a liquorice-like aftertaste at high usage levels. Thaumatin is highly water-soluble, and stable to heating and stable under acidic conditions.
