Abstract

The invention provides a process of purifying Rubusoside from the Rubus suavissimus S. Lee plant extract. 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, confectioneries, bakeries, cookies, chewing gums, and alike.

First claim

I claim:

1. A process for purifying Rubusoside from Rubus suavissimus extract comprising the steps of:
a. providing an extract of Rubus suavissimus S. Lee leaves;
b. dissolving the extract in a first aqueous alcoholic solution to obtain a first mixture;
c. inducing crystallization in the first mixture by temperature gradient treatment;
d. filtering the first mixture from (c) to obtain a first precipitate and a first filtrate;
e. dissolving the first precipitate in a se…
