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.
Claims13
A process for preparing Rubusoside from steviol glycosides of Stevia rebaudiana comprising the steps of:
- A) providing a solution comprising Stevioside;
- B) adding 2000 fungal β-glucanase (FBG) units of an enzyme composition having fungal β-glucanase activity to the solution comprising Stevioside to obtain a reaction mixture;
- and
- C) incubating the reaction mixture at 28-50° C. for 12-48 hours to facilitate transformation of Stevioside to Rubusoside to obtain a reaction mixture containing Rubusoside.
