Abstract:
1. A crystalline salt of monatin selected from the group consisting of: (a) ammonium salt of a racemic mixture of (2S,4S)-monatin and (2R,4R)-monatin which has PXRD peaks at diffraction angles 2θ CuKα of 6.0°, 12.1°, 15.2°, 18.6°, 21.3°, 23.2°, and 25.0°; (b) sodium salt of a racemic mixture of (2S,4S)-monatin and (2R,4R)-monatin which has PXRD peaks at diffraction angles 2θ CuKα of 4.4°, 13.6°, 15.2°, 16.7°, 22.2°, and 24.4°; and (c) potassium salt of a racemic mixture of (2S,4S)-monatin and (2R,4R)-monatin which has PXRD peaks at diffraction angles 2θ CuKα of 5.9°, 18.7°, 20.1°, and 23.8°.
