17 Claims

1. A method of preparing a concentrated solution having at least about 2 wt % rebaudioside M content comprising:

a. combining (i) a crystalline steviol glycoside composition comprising rebaudioside M, (ii) at least one surfactant selected from a cationic surfactant and an anionic surfactant, and (iii) an aqueous solution to provide a mixture;

b. heating the mixture to provide a clear solution; and

c. cooling the clear solution to about room temperature to provide a concentrate;

wherein the weight ratio of the crystalline steviol glycoside composition comprising rebaudioside M to the at least one surfactant is about 5:1 to about 1:1.
