Abstract
The present invention relates to a stevioside M crystal form, a preparation method therefor and a use thereof, and specifically, relates to a naturally extracted high-intensity sweetener, i.e., a stevioside M crystal form A, the preparation method therefor and the user thereof. By means of comprehensive characterization of the new crystal form, the new crystal form is found to have advantages such as a high degree of crystallinity, good stability, and low hygroscopicity, and is applicable to a more comprehensive field of application. The preparation method in the present invention is simple and easy to operate, has high selectivity and good reproducibility, and can stably obtain the target crystal form.
