Abstract
Abstract A heat-stable sweetening composition containing a peptide sweetener such as thaumatin is obtained by mixing the sweetener with gelatin at a weight ratio of gelatin to sweetener of less than 100:1. Solid forms can be prepared by drying a co-solution of the sweetener and gelatin in water, preferably containing an edible acid.

Claim 9
Dependent Claim
35 words
A composition according to any one of claims 1 to 7, containing the protein sweetener in combination with at least one component selected from the group consisting of other sweeteners, taste modifiers and flavouring agents.
Claim 10
Dependent Claim
22 words
