Abstract

The invention describes compositions that include rebaudioside D, processes to produce rebaudioside D and formulations that provide ratios of rebaudioside A to rebaudioside D to decrease the aftertaste of rebaudioside A.

1 - 10 . (canceled) 
     
     
         11 . A method to decrease bitterness of purified rebaudioside A in a sweetener composition comprising purified rebaudioside A, comprising:
 adding to the sweetener composition purified rebaudioside D in an amount that is 1% or greater by weight of the final composition.   
     
     
         12 . The method of  claim 11 , wherein purified rebaudioside D is added in an amount that is 5% or greater by weight of the final composition. 
     
     
         13 . The method of  claim 11 , wherein the combined percentage of rebaudioside A and rebaudioside D in the sweetener composition equals 100% of total steviol glycosides in the sweetener composition. 
     
     
         14 . The method of  claim 11 , wherein the sweetener composition consists of rebaudioside A and rebaudioside D. 
     
     
         15 . A method to decrease aftertaste of rebaudioside A in a sweetener composition comprising purified rebaudioside A, comprising:
 adding to the sweetener composition purified rebaudioside D in an amount that is 0.5% or greater by weight of the final composition.   
     
     
         16 . The method of  claim 15 , wherein purified rebaudioside D is added in an amount that is 1% or greater by weight of the final composition. 
     
     
         17 . The method of  claim 15 , wherein purified rebaudioside D is added in an amount that is 5% or greater by weight of the final composition. 
     
     
         18 . The method of  claim 15 , wherein the sweetener composition consists of rebaudioside A and rebaudioside D. 
     
     
         19 . A method to decrease bitterness of rebaudioside A in a sweetener composition, comprising:
 adding to the sweetener composition purified rebaudioside D in an amount that is 5% or greater by weight of the final composition,   wherein the sweetener composition consists of purified rebaudioside A and purified rebaudioside D.   
     
     
         20 . A method to decrease an aftertaste of a sweetener composition comprising rebaudioside A, comprising the steps of:
 preparing a purified preparation of rebaudioside A;   preparing a purified preparation of rebaudioside D; and,   adding the purified preparation of rebaudioside D to the purified preparation of rebaudioside A in an amount sufficient to decrease an aftertaste of the rebaudioside A preparation,   wherein the amount of purified rebaudioside D is greater than 1% by weight of the final sweetener composition.
