Embodiment 1

[0039] At room temperature, 20 g of steviolbioside with a material purity of 99.5% was added to 100 mL of methanol, stirred for 12 hours, and then filtered to obtain a white solid, which was vacuum-dried at 25°C to obtain steviolbioside crystal form A.

Embodiment 2

[0041] At 50°C, 30g of steviolbioside with a material purity of 99.5% was added to 100mL of methanol, stirred for 12 hours, and then filtered to obtain a white solid, which was vacuum-dried at 25°C to obtain steviolbioside crystal form A.

Embodiment 3

[0043] At 50°C, 40g of steviolbioside with a substance purity of 80% was added to 100mL of methanol, stirred for 12 hours, and then filtered to obtain a white solid, which was vacuum-dried at 25°C to obtain steviolbioside crystal form A.

Abstract

The invention belongs to the technical field of a sweetening agent, and particularly relates to a rebaudioside crystal form A, a preparation method, a food compound and application. The rebaudioside crystal form A is subjected to diffraction analysis by X-ray powder obtained through Cu-Ka ray measurement; the 2 theta angle expressed by degree at least has the obvious feature diffraction peaks in positions of 4.72, 7.20, 12.24, 13.40, 14.16, 14.74, 16.54, 17.04, 18.18 and 18.98. The solid chemical analysis measures such as XRPD, DSC, TGA and DVS are used for performing comprehensive expression on the crystal form A; the crystal form A is discovered to have the advantages of high degree of crystallinity, high stability, high water solubility, small moisture absorption performance and the like; the crystal form A is suitable for wider application fields. The preparation method related by the invention has the advantages that the method is simple; the operation is easy; the selectivity is wide; the repeatability is good; the target crystal form can be stably obtained.

Description

technical field [0001] The invention belongs to the technical field of sweeteners, and in particular relates to steviolbioside crystal form A, its preparation method, food composition and application. Background technique [0002] Stevia belongs to the small Compositae plant and is native to the Amambai Mountains on the border between Paraguay and Brazil in South America. The sweetness of glycosides contained in the leaves is 150-300 times that of sucrose. Use it as a low-calorie food, instead of synthetic sugar, and for the treatment of diabetes, obesity, heart disease and the prevention and treatment of children's teeth. Stevioside refers to the white powdered steviol glycoside extracted from Stevia rebaudiana, which is a pure natural, high sweetness, zero calorie (zero calorific value) food additive (sweetener), and natural sugar substitute. Stevia sugar is not absorbed by the human small intestine in the human body, but is converted into steviol sugar which cannot be a...
