The invention relates to a process for the preparation of hydroxy fatty acid esters which are solid at room temperature and have improved melting behavior, prepared in accordance with a process in which, in the presence of an enzyme, di- or polyols having at least two primary and optionally secondary or tertiary hydroxyl groups, and hydroxy fatty acids and/or hydroxy fatty acid alkyl esters, optionally in a solvent, are reacted, where necessary at a reduced pressure relative to the atmosphere, and at temperatures between 20°C and 110°C and with removal of the water of reaction or alcohol of reaction which forms.
