ABSTRACT A .beta.-hydroxyamino acid is produced by causing a strongly acidic ion-exchange resin to adsorb thereon aziridine-2-carboxylic acid or its derivative represented by the general formula (II): Image (II) wherein R1 represents a hydrogen atom, methyl group or a substituted or unsubstituted phenyl or pyridyl group, R2 means a hydrogen atom or a methyl group, and X is -CO2H, -CO2M(M: an alkali metal or alkaline earth metal), -CO2R3(R3: a lower alkyl group having 1-5 carbon atoms or an aralkyl group), -CONH2 or -CN, with a proviso that X is other than -CO2H and -CO2M when R1 and R2 are individually a hydrogen atom; and then heating the thus-adsorbed aziridine- 2-carboxylic acid or its derivative in the presence of water. The above process is employed to produce DL-serine, threonine, .beta.-hydroxyvaline, .beta.-hydroxyphenylalanine, etc.
