Abstract

Methods of preparing freeze dried powders comprising rebaudioside M and rebaudioside D are provided herein. The freeze dried powders produced by the disclosed methods exhibit improved aqueous solubility over known forms and compositions of rebaudioside M and rebaudioside D. Methods of preparing consumables, e.g. beverages, with the freeze dried compositions are also detailed herein.

First claim

The invention claimed is:

1. A method of preparing a freeze dried powder with improved aqueous solubility comprising:
a. preparing a mixture consisting of water and a crystalline steviol glycoside composition consisting essentially of about 75% to about 90% Reb M by weight, about 10% to about 25% Reb D by weight; and wherein the mixture has a solids content from about 10% to about 30% by weight;
b. heating the mixture to a temperature from about 70° C. to 98° C. for a time sufficient to dissolve the crystalline composition and provide a clear solution; and
c. freeze drying the clear solution to provide a freeze dried powder.

2. The method of claim 1 , wherein step a. further comprises adding a food grade alcohol.

3. The method of claim 1 , wherein the freeze drying is performed with a lyophilizer.

4. The method of claim 1 , wherein freeze drying comprises:
(i) freezing the solution to provide frozen pellets; and
(ii) sublimating the frozen pellets to provide a freeze dried powder.

5. The method of claim 1 , wherein step a. is performed in a slurry tank.

6. The method of claim 5 , wherein step b. is performed with a heat exchanger.

7. The method of claim 6 , wherein freeze drying comprises:
(i) freezing the solution to provide frozen pellets; and
(ii) sublimating the frozen pellets using a continuous or batch freeze dryer.

8. The method of claim 1 , wherein the freeze dried powder has an aqueous solubility of at least about 0.5%.

9. A method of preparing a consumable comprising (i) providing a consumable matrix and (ii) adding a freeze dried powder produced by the method of claim 1 , or a composition comprising a freeze dried powder produced by the method of claim 1 , to provide a consumable, wherein the freeze dried powder has an aqueous solubility of at least about 0.5%.

10. The method of claim 9 , wherein the freeze dried powder has an aqueous solubility of at least about 1.0%.

11. The method of claim 9 , wherein the consumable is a beverage or beverage product.

12. A freeze dried powder produced by the method of claim 1 .

13. The method of claim 1 , wherein the mixture is heated in step b. for 45 minutes or less.

14. The method of claim 1 , wherein the mixture in step b. is not boiled or refluxed.

15. The method of claim 1 , wherein the heating is minimized to what is necessary to provide a clear solution, and the clear solution is then directly freeze dried.
