Abstract
The invention provides a process of producing Rubusoside from steviol glycosides of Stevia rebaudiana plant. The process is useful for producing high purity Rubusoside with purity greater than 95% (dry basis). High purity rubusoside is useful as in combination with other caloric and non-caloric sweeteners as well as non-caloric sweetener in various food and beverage compositions. The high purity rubusoside is useful as non-caloric sweetener in edible and chewable compositions such as any beverages, confectionaries, bakeries, cookies, chewing gums, and alike.
Claims12
A process for preparing Rubusoside from steviol glycosides of Stevia rebaudiana, the process comprising:
- a. providing a solution comprising Stevioside in water;
- b. forming a reaction mixture by adding an effective amount of hesperidinase to the water containing the Stevioside;
- c. incubating the reaction mixture for 12-48 hours to facilitate the conversion of 95%-100% of the Stevioside initially in the reaction mixture to Rubusoside;
- d. inactivating the hesperidinase by applying heat to the reaction mixture to terminate the transformation reaction;
- and
- e. purifying the Rubusoside from the reaction mixture.
