    摘要： [Problems] To provide a process for producing monatin where steric configuration of 2-position is in an R configuration or a salt thereof by isomerization of 2-position of monatin where steric configuration of 2-position is in an S configuration. [Means for Resolution] A process for producing monatin where steric configuration of 2-position is in an R configuration or a salt thereof, characterized in that, the process contains a step where isomerization reaction of 2-position of monatin in which steric configuration of 2-position is in an S configuration is carried out in a mixed solvent of water and organic solvent in the presence of an aldehyde and, after that, a step where monatin in which steric configuration of 2-position is in an R configuration or a salt is crystallized.

    摘要： 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.
