Abstract

Un procédé en vue d'extraire la phénylalanine des bouillons obtenus par des procédés enzymatiques. Ce procédé comprend les étapes consistant à : floculer et filtrer le bouillon, concentrer le filtrat puis, par filtration, séparer l'acide cinnamique obtenu, puis décolorer et concentrer le filtrat pour obtenir des cristaux de phénylalanine d'un très haut degré de pureté.
