Abstract

The present application relates to a method for producing D-psicose, the method comprising the steps of: putting a composition containing a D-psicose borate complex into a chromatography comprising divalent cations; and separating the composition containing the D-psicose borate complex into a D-psicose-containing fraction (i) and a borate-containing fraction (ii).
