Title (EN) A METHOD OF THE REMOVAL OF MONOSACCHARIDE IN OLIGOSACCHARIDES PRODUCTION
(FR) PROCÉDÉ D’ÉLIMINATION DU MONOSACCHARIDE DANS LA PRODUCTION D’OLIGOSACCHARIDES
Abstract:
(EN) A method for removal of the monosaccharide in oligosaccharides production which includes the step of culturing the yeast. A further step involves mixing 8%- 12% (W/W) of yeast based on the weight of oligosaccharides and 0.1%-0.5% (W/W) of carbamide as nitrogen source with raw oligosaccharide syrup, and then adjusting the pH value to 4.5 - 6.0. A further step involves culturing the above oligosaccharides syrup at 23°C - 26°C for 20 -30 hours with intermittent agitation.
(FR) La présente invention concerne un procédé d’élimination du monosaccharide dans la production d’oligosaccharides qui comprend l’étape de culture de la levure. Une autre étape comporte le mélange de 8 à 12 % (P/P) de levure basé sur le poids d’oligosaccharides et de 0,1 à 0,5 % (P/P) de carbamide comme source d’azote avec du sirop d’oligosaccharides brut, suivie du réglage de la valeur du pH à 4,5 à 6,0. Une autre étape comporte la culture du sirop d’oligosaccharides susmentionné à une température de 23 à 26 °C pendant 20 à 30 heures avec agitation intermittente.
