Abstract
The present application provides compositions comprising one or more glycosylated steviol glycosides (GSGs) and/or one or more steviol glycosides (SGs). In other aspects, the present application provides methods for (1) preparing SG/GSG compositions; (2) enhancing the sweetness of an orally consumable composition; and (3) improving the taste profile or flavor of an orally consumable composition, among other things.
Claims51
A composition comprising one or more glycosylated steviol glycosides (GSGs) and/or one or more steviol glycosides (SGs), wherein the one or more SGs are selected from Table A or Table B, wherein the one or more SGs conform to at least one SG-group selected from the group consisting of SG-1G, SG-2G, SG-3G, SG-4G, SG-5G, SG-6G, SG-1G1R, SG-2G1R, SG-3G1R, SG-4G1R, SG-5G1R, SG-6G1R, SG-1G1X, SG-2G1X, SG-3G1X, SG-4G1X, SG-5G1X, and combinations thereof, and further wherein the one or more SGs are in a total amount of 0.1-99.5 wt % of the composition;
- and further comprising one or more GSGs in a total amount of 0.1-99.5 wt % of the composition, wherein the one or more GSGs are further glycosylation products from one or more SGs in Table A, and wherein the one or more GSGs comprise one or more rhamnose moieties, one or more deoxyhexose moieties, or combination thereof.
A method for the preparation of a GSG composition, comprising the steps of:
- (a) dissolving a glucose-donor material in water to form a liquefied glucose-donor material;
- (b) adding a SG composition to liquefied glucose-donor material to obtain a reaction mixture;
- (c) adding an effective amount of an enzyme to the reaction mixture, wherein the enzyme catalyzes the transfer of glucose moieties from the glucose-donor molecule to SGs in the SG composition to the mixture;
- (d) incubating at a desired temperature for a desired length of reaction time to glycosylate SGs of the SG composition with glucose moieties present in the glucose-donor material;
- (e) inactivating the enzyme;
- (f) removing the enzyme from the reaction mixture;
- and
- (g) drying the resulting solution of GSGs, residual SGs and dextrins.
