Thaumatin is a low-calorie sweetener and flavour modifier. It is a mixture of proteins isolated from the katemfe fruit. The Thaumatoccus danielli tree is native to the tropical rainforest areas of West and Central Africa.

Fruit of the Tree used to make Thaumatin

It is a sweet protein that can replace sugar in food and will not raise blood sugar or insulin levels.

Ninety-nine per cent of all fruits in the world derive their sweetness from sugar. Yet, there are very few fruits that contain a sweet protein, rather than a sugar.

Proteins used as a sweetener have a significant advantage over sugar – they are digested by like any other protein. Protein-sweetened chocolate cannot lead to obesity nor contribute to diabetes.

Proteinaceous Food Ingredient

The sugar substitute market is worth around $9 billion a year

A completely natural product, Thaumatin, is extracted from fruits by water-based physical extraction.

It is a proteinaceous food ingredient up to 3 000 times sweeter than sugar and is non-carcinogenic with no glycaemic index. Thaumatin is water-soluble, stable to heating and its pH ranges between 2 and 8.

The body digests Thaumatin in the same way as any other protein and it is stable in food and drink formulations. It is a powerful masking agent and improves palatability. Thaumatin is a protein sweetener.

The calorie intake of thaumatin is negligible (4.1 cal/g = 17 J/g). It modifies the sensory quality of products – masking unpleasant or bitter tastes. The powder is also soluble in glycerin, propylene, ethanol and polyols like sorbitol.
