Document Type and Number:
WIPO Patent Application WO/2019/168082
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a crystal of rebaudioside D that exhibits high solubility in water. In one embodiment, the present invention provides a rebaudioside D crystal having a crystalline form α that shows peaks in X-ray diffraction (CuKα:λ=1.5405 Å) at two or more positions selected from the group consisting of 2θ=6.7±0.2 deg, 10.8±0.2 deg, 12.9±0.15 deg, and 22.2±0.2 deg.
