Embodiment 1

[0040] At room temperature, 20 g of stevioside B with a material purity of 100% was added to 100 mL of methanol, stirred for 12 hours, and then filtered to obtain a filtrate and a white solid, which were vacuum-dried at 25°C to obtain stevioside Beta glycoside crystal form G.

Embodiment 2

[0042] At 50°C, add 20g of stevioside B with a material purity of 100% into 100mL of methanol, stir for 12 hours, and filter to obtain a filtrate and a white solid, which are vacuum-dried at 25°C to obtain stevia Sugar B glycoside crystal form G.

Embodiment 3

[0044] At room temperature, 40 g of stevioside B with a material purity of 50% was added to 100 mL of methanol, stirred for 12 hours, and filtered to obtain a filtrate and a white solid. The filtrate and the white solid were vacuum-dried at 25° C. respectively to obtain stevioside B. Glycoside crystal form G.

Abstract

The invention belongs to the technical field of sweeteners, and in particular relates to a stevia glucoside B crystal form G as well as a preparation method, a food composition and the application thereof. The stevia glucoside B crystal form G is measured by a Cu-Ka ray, so that X-ray powder diffraction analysis is obtained; a 2 theta valve expressed in degrees at least has obvious characteristic diffraction peaks at 3.93, 13.45, 16.62, 18.33, 19.90, 23.95 and 28.02. After solid chemical analysis methods such as XRPD, DSC, TGA, DVS and the like are used for carrying out comprehensive characterization on the crystal form G, the crystal form G is found to have the advantages of being high in degree of crystallinity, good in stability and water solubility, low in moisture property and the like, thus being suitable for wider application fields. The preparation method is simple, easy to operate, more in selectivity and good in reproducibility, and can be used for stably obtaining the target crystal form.

Description

technical field [0001] The invention belongs to the technical field of sweeteners, and in particular relates to steviol glycoside B crystal form G, its preparation method, food composition and application. Background technique [0002] Stevia is a small Compositae plant native to the Amambai Mountains on the border between Paraguay and Brazil in South America. There are 9 identified sweet components of stevia: stevioside, steviobioside, stevioside A-stevioside F and dulcoside G. They all belong to glycoside compounds and have the same aglycone-steviol; the difference is only in the type, quantity and configuration of the sugar bound on the glycoside bond. Because they are all glycosides with sweet taste, they are collectively called Steviol Glycosides. Among them, stevioside B is a stevioside compound with a sweetness about 150 times that of sucrose. Stevioside B (RebGudiosideB, RB), its structural formula is as follows: [0003] [0004] Among stevia extracts, stevio...
