1. A process for producing a stevia composition comprising rebaudioside B, comprising the steps of:
providing a stevia sweetener; providing a biocatalyst capable of hydrolyzing β-glucosyl ester bonds in the stevia sweetener; dissolving the stevia sweetener and adding the biocatalyst to make a reaction mixture; incubating the reaction mixture for about 12 to 48 hours to at least partially hydrolyze β-glucosyl ester bonds in the stevia sweetener; cooling the mixture to about 10-30° C. and adjusting the pH with acid to about pH 3.0-4.0; incubating the mixture at low temperature to obtain a precipitate; separating the precipitate and washing the precipitate with water; and drying the washed precipitate to obtain the stevia composition.
