thermal stability is affected mainly by pH, presence of oxygen, and other soluble matter, especially
polysaccharides. Talin can be pasteurised or UHT-sterilised in non-alcoholic beverages at pH 2.8–3.5
Thaumatin is also combined with saccharin and L-glucose, with xylitol and others. Thaumatin
admixed with glycyrrhizin and amino acids is marketed in Japan as San Sweet T-1 and T-100. It will
remain stable indefinitely when freeze-dried or spray-dried, if stored under ambient conditions. It will
also remain stable at 120°C in canning operations and under pasteurisation and UHT conditions.
Thaumatin will impart licorice-like taste at higher levels; therefore, its use as the only source of
sweetness is limited to applications where the required sweetness is less than the equivalent of 10%
sucrose.
SYNERGISTS: Synergistic with saccharin, acesulfame K. Talin, when used with either sucrose or Acesulfam-K or
stevioside, showed some degree of synergism. Thaumatin also synergises with monosodium glutamate
and 5¢-nucleotides to increase the flavour enhancement
FOOD SAFETY ISSUES: No adverse effects in short-term tests. Not allergenic, mutagenic or teratogenic
