摘要：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.

主权项：1. A process for preparing Rubusoside from steviol glycosides of Stevia rebaudiana comprising the steps of: a. providing a solution comprising Stevioside; b. providing an enzyme composition comprising at least one enzyme selected from the group comprising rhamnosidase, β-glucosidase, β-glucanase, hesperidinase, naringinase, pectinase, cellulase, hemicellulase, xylanase; c. adding the enzyme composition to the solution comprising Stevioside to obtain reaction mixture; d. incubating the reaction mixture to facilitate complete or partial transformation of Stevioside to Rubusoside; e. recovering and purifying high purity Rubusoside from reaction mixture.
