Another example is the Thaumatin
plant in West Africa, which is now denied to villagers, thanks to a patent bagged by the University of California.
plant protein, 100,000 times sweeter than sugar, is the sweetest substance known.
These are acesulfame-K (E950), aspartame (E951), aspartame-acesulfame salt (E962), cyclamate (E952), neohesperidine DC (E959), saccharin (E954), sucralose (E955), thaumatin
(E957) and neotame (E961).
The main sweeteners used in Brazil are: sucralose, acesulfame-k, stevioside, aspartame, thaumatin
In this context, it is worth mentioning that thaumatin
-like proteins have antifungal activity but no sweet taste while the converse is true of thaumatin
although they are highly homologous in structure (Ye et al.
But the largest molecule with a flavor impact that Roger Boulton of the University of California, Davis, could think of is thaumatin
, a synthetic sugar substitute, which comes in at about one twentieth of micron--.
A natural product extracted from thaumatin
, an indigenous African fruit, has been introduced by RFI Ingredients, Blauvelt, NY, under the brand name Talin[R].
occurs naturally in a West African plant, and is one of the most potent sweet substances found.
Scientists already know the structures of two other sweet proteins, thaumatin
and monellin (SN: 5/10/97, p.
7, 1995, relates to XOMA's recombinant production of Thaumatin
, a low-calorie protein that can be used as a flavor enhancer.
-like proteins comprise a class of polypeptides that share homology to thaumatin
, the sweet protein from Thaumatococcus danielli (Bennett) Benth.
for mistakenly attributing his company's unique food ingredient, talin thaumatin
, to another company.
