Preparation of D-histidine and derivatives thereof from L-histidine

D-histidine and its derivatives are manufactured from L-histidine, by mixing L-histidine and tartaric acid with an aldehyde in acetic acid medium and thereafter precipitating D-histidine tartrate from the reaction mass. Pure D-histidine can then be recovered from the crude D-histidine tartrate.
