Beschreibung
Zusammenfassung:	A process is disclosed for improving the heat stability of an aqueous lactic acid composition, comprising a heat treatment step and further comprising contacting the aqueous lactic acid composition with at least one adsorbent selected from the group consisting of activated carbons, polymeric adsorbents, ion exchange resins and bleaching clays. L'invention concerne un procédé pour améliorer la stabilité thermique d'une composition aqueuse d'acide lactique, comprenant une étape de traitement thermique et comprenant en outre la mise en contact de la composition aqueuse d'acide lactique avec au moins un adsorbant choisi dans le groupe constitué par les carbones activés, les adsorbants polymères, les résines échangeuses d'ions et les argiles de blanchiment.
