Definition of thaumatin in English:



  • A sweet-tasting protein isolated from a West African fruit (Thaumatococcus danielli, family Marantaceae), used as a sweetener in food.

    ‘Intense sweeteners permitted for use in Australian and New Zealand foods are acesulphame potassium, aspartame, cyclamates, saccharin, sucralose, alitame, thaumatin and neotame (code number yet to be finalised).’
    • ‘In the above examples, the amount of thaumatin can be replaced by about 2.5 times the amount of monellin.’
    • ‘The method includes the mechanical dissolution of the fiber parts containing thaumatin and, since the protein is very easy to dissolve in water, the aqueous extraction.’
