Zusammenfassung:The present application relates to a method for preparing a D-psicose crystal comprising 98%(w/w) or more of D-psicose and 0.05%(w/w) or less of ethanol on the basis of 100%(w/w) of the entire crystal, the method comprising: a first step of mixing an organic solvent and a solution containing D-psicose; and a second step of injecting a seed into the mixture solution obtained in the first step, and then cooling same, thereby obtaining a maskette comprising a D-psicose crystal. Therefore, the present invention can improve the yield of D-psicose crystals from a D-psicose solution, and can prepare D-psicose crystals having no offensive taste/odor and having a sufficient size and an appropriate shape for mass production.
