ABSTRACT:
The present invention provides an organic amine salt of monatin, or crystal form thereof, and its application as well as a method for resolving the stereoisomers of monatin by forming its salt. The present invention further provides a salt form of monatin that is useful as a sweetening agent or as the active ingredient of a sweetener. The present invention also provides a method for preparing a salt of a particular stereoisomer of monatin with an organic amine by utilizing the difference of crystallinity or solubility of the salt of the stereoisomer of monatin with the organic amine. The present invention also relates to a use of the salt in a method for preparing a metal salt of monatin in which the organic amine is replaced by a metal such as sodium, potassium, or the like.
