Steviol glycoside isomers are provided having the formula: wherein R1 may be hydrogen, 1-beta-D-glucopyranosyl, or 2-(1-beta-D-glucopyranosyl)-1-beta-D-glucopyranosyl, and R2 may be hydrogen, 1-beta-D-glucopyranosyl, 2-(1-beta-D-glucopyranosyl)-1-beta-D-glucopyranosyl, 2,3-bis(1-beta-D-glucopyranosyl)-1-beta-D-glucopyranosyl, 2-(1-alpha-L-rhamnopyranosyl)-1-beta-D-glucopyranosyl, 2-(1-alpha-L-rhamnopyranosyl)-3-(1-beta-D-glucopyranosyl)-1-beta-D-glucopyranosyl, or 2-(1-beta-D-xylopyranosyl)-3-(1-beta-D-glucopyranosyl)-1-beta-D-glucopyranosyl. Methods for making steviol glycoside isomers are also disclosed. These compounds may be present in food and beverage products as non-nutritive sweeteners.
