Crystals of (2R,4R)-monatin potassium salt which exhibit an X-ray powder diffraction pattern having characteristic peaks at diffraction angles 2θ of 5.5°, 7.2°, 8.1°, 8.9°, and 16.3°, by powder X-ray diffraction (Cu—Kα radiation), are superior in sweetness, preservation stability, solubility, and color stability. |
