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.
