Title
(EN) PURIFICATION OF MAGNESIUM LACTATE FROM FERMENTATION BROTHS HAVING HIGH AMOUNTS OF IMPURITIES
(FR) PURIFICATION DE LACTATE DE MAGNÉSIUM À PARTIR DE BOUILLONS DE FERMENTATION AYANT DES QUANTITÉS ÉLEVÉES D'IMPURETÉS
Abstract
(EN)
A process for efficient purification of magnesium lactate from fermentation broths derived from non-homogeneous feedstocks that contain soluble and insoluble impurities is provided. The fermentation broth, having high amounts of impurities and containing magnesium lactate in a soluble form, is separated from insoluble impurities, concentrated to particularly high concentrations of the magnesium lactate at elevated temperatures, and subsequently cooled by gradual and controlled cooling such that magnesium lactate crystals of high purity are formed.

Procédé de purification efficace de lactate de magnésium à partir de bouillons de fermentation dérivés de charges de départ non homogènes contenant des impuretés solubles et insolubles. Le bouillon de fermentation, ayant des quantités élevées d'impuretés et contenant du lactate de magnésium sous une forme soluble, est séparé des impuretés insolubles, concentré pour atteindre des concentrations particulièrement élevées en lactate de magnésium à des températures élevées, puis refroidi par refroidissement progressif et contrôlé de telle sorte que des cristaux de lactate de magnésium de haute pureté sont formés.
