Abstract
L'INVENTION CONCERNE LA PREPARATION DE LA RIBOFLAVINE. ON RECUEILLE LA RIBOFLAVINE A PARTIR D'UN BOUILLON DE FERMENTATION EN DILUANT LE BOUILLON AVEC UNE QUANTITE PREDETERMINEE D'EAU, EN CENTRIFUGEANT LE BOUILLON DILUE DE MANIERE A FORMER UNE BOUE, EN REMETTANT LA BOUE EN SUSPENSION AVEC UNE QUANTITE PREDETERMINEE D'EAU ET EN CENTRIFUGEANT LA BOUE REMISE EN SUSPENSION POUR OBTENIR UN PRODUIT UTILISABLE DIRECTEMENT COMME SUPPLEMENT POUR LA NOURRITURE D'ANIMAUX OU SUSCEPTIBLE DE PURIFICATION SUPPLEMENTAIRE POUR UTILISATION PHARMACEUTIQUE. EVENTUELLEMENT, ON TRAITE LE BOUILLON OU LA BOUE REMISE EN SUSPENSION AVEC UNE ENZYME AVANT LA CENTRIFUGATION. CE PROCEDE PERMET D'OBTENIR UNE RIBOFLAVINE PLUS PURE.
