The present invention discloses a process for producing erythritol by fermentation using a polysaccharide negative erythritol producing strain and recovering erythritol crystals by direct crystallisation from the unrefined micro-organism-free fermentation broth. Direct crystallisation of erythritol is performed at dry substance higher than 80% w/w. Recovery of erythritol crystals is at least 85% and purity of erythritol crystals is at least 99% w/w.
La présente invention a pour objet un procédé de production d'érythritol par fermentation à partir d'une souche productrice d'érythritol et non formatrice de polysaccharides, et par récupération des cristaux d'érythritol par cristallisation directe à partir du bouillon de fermentation non raffiné et exempt de microorganismes. La cristallisation directe de l'érythritol s'effectue à un pourcentage de matière sèche supérieur à 80 % p/p. La récupération des cristaux est d'au moins 85 % et leur pureté est d'au moins 99 % p/p.
