Abstract

The invention relates to a method for the purification of a fermentatively prepared alpha-hydroxy acid on an industrial scale, in which an alpha-hydroxy acid with a color (fresh) of not more than 10,000 APHA units is subjected to at least two crystallization steps, with the crystallization steps being carried out in cooling crystallization devices, melting crystallization devices, evaporative crystallization devices and/or adiabatic crystallization devices.
