The present invention relates to a process for the recovery of an organic acid from a fermentation broth which comprises drying the fermentation broth to obtain a dried product, adding the dried product to a lower alcohol in the presence of an acid, and then removing the insoluble material to obtain an organic acid. In accordance with the recovery process of the present invention, organic acids of a high purity can be recovered in high yields from the whole fermentation solution containing various impurities with fewer steps as compared with conventional methods.
L'invention concerne un procédé pour la récupération d'acides organiques à partir d'un jus de fermentation qui consiste à sécher le jus de fermentation pour obtenir un produit séché, à ajouter le produit séché à un alcool inférieur en présence d'un acide puis à retirer la matière insoluble pour obtenir un acide organique. Selon le procédé de récupération, les acides organiques de grande pureté peuvent être récupérés en grandes quantités à partir de la solution de fermentation contenant plusieurs impuretés en moins d'étapes par rapport aux procédés classiques.
