Document Type and Number:
WIPO Patent Application WO/2017/161987
Kind Code:
A1
Abstract:
The present invention relates to the naturally extracted high intensity sweetener stevioside, and specifically relates to a novel crystal form of steviolbioside, and a manufacturing method and application therefor. The novel crystal form has been comprehensively characterised by means of solid chemical analysis methods such as XRPD, DSC, TGA, and DVS, discovering that the novel crystal form has the advantages of high crystallinity, good stability, and low hygroscopicity, and is therefore suitable for use in a wide range of fields. The manufacturing method disclosed in the present invention is simple and easy to operate, has high selectivity and good reproducibility, and can stably obtain the target crystal form.
