[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.
A process for producing monatin in which the steric configuration at the 2-position is in the R configuration or a salt thereof,
A process for producing (2R,4R) monatin or a salt thereof,
