| 摘要 |
Steviol glycoside isomers are provided having the formula (II): wherein R1may be hydrogen, 1-ß-D-glucopyranosyl, or 2-(1-ß-D-glucopyranosyl)-1-ß-D- glucopyranosyl, and R2 may be hydrogen, 1-ß-D-glucopyranosyl, 2-(1-ß-D-glucopyranosyl)- 1-ß-D-glucopyranosyl, 2,3 -bis(1-ß-D-glucopyranosyl)-1-ß-D-glucopyranosyl, 2-(1-a-L- rhamnopyranosyl)-1-ß-D-glucopyranosyl, 2-(1-a-L-rhamnopyranosyl)-3 -(1-ß-D- glucopyranosyl)-1-ß-D-glucopyranosyl, or 2-(1-ß-D-xylopyranosyl)-3 -(1-ß-D- glucopyranosyl)-1-ß-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. |
