Abstract
Provided is a low-odor, high-stability ergothioneine crystal, which belongs to the field of compound crystals The powder X-ray diffraction pattern of the ergothioneine crystal, measured using Cu-Kα radiation and expressed in terms of 2θ, has characteristic peaks at least at 9.50±0.2°, 15.52±0.2°, 19.06±0.2°, 24.88±0.2°, 25.48±0.2°, 28.74±0.2°, 29.22±0.2°, and 35.10±0.2°. The new crystal form of ergothioneine has excellent photostability, good resistance to hygroscopicity, and a high decomposition temperature tolerance.
