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).’
    • ‘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.’
    • ‘In the above examples, the amount of thaumatin can be replaced by about 2.5 times the amount of monellin.’


1970s: from modern Latin thaumat- (from Greek thauma, thaumat- marvel) + -in.
