Abstract

Steviol glycoside solutions, and methods of making steviol glycoside solutions, are described. The steviol glycoside solutions are clear and stable, and have clear solution stability, for extended periods of time.

Claims (13)

1. A method of making a stable, clear liquid steviol glycoside ingredient solution, comprising the steps of:

a. providing a steviol glycoside;

b. providing a solvent system comprising 10-100% w/w propylene glycol; and

c. combining the steviol glycoside in the solvent with constant agitation and while maintaining the temperature of the solvent until the steviol glycoside is dissolved to provide a stable, clear liquid steviol glycoside ingredient solution having a steviol glycoside concentration of from about 5% to about 40% w/w;

wherein the stable, clear liquid steviol glycoside ingredient solution has a clear solution stability at a steviol glycoside concentration of up to 40% w/w for 45-60 days.

2. The method of claim 1 , wherein the steviol glycoside is made by a gradient beating and gradient cooling process.

3. The method of claim 1 , wherein the propylene glycol is 10-50% w/w.

4. The method of claim 1 , wherein the solvent system is heated prior to combining the steviol glycosides in the solvent.

5. The method of claim 4 , wherein the solvent system is heated to a temperature of about 70° C. to about 95° C.

6. The method of claim 1 , wherein the steviol glycoside ingredient solution is cooled after dissolving the steviol glycoside.

7. The method of claim 6 , wherein the steviol glycoside ingredient solution is cooled to about 20° C.

8. The method of claim 1 , wherein the steviol glycoside ingredient solution is visibly clear and free of visible cloudiness or turbidity.

9. The method of claim 1 , wherein the steviol glycoside is selected from one or more of the following: Reb A, Reb B, Reb C, Reb D, Reb E, Reb F, Reb I, Reb M, Reb N, Reb O, Reb Q, Reb R, Dulcoside A, Rubusoside, Stevioside, Steviolbioside, and combinations thereof.
