Abstract

The present invention relates to an industrial process for producing a lactic ester containing in total at least seven carbon atoms, from a fermentation liquor containing ammonium lactate in order to avoid the inherent production of gypsum, with a high yield and according to which the loss of lactic ester in the form of lactamide is limited as much as possible.
