Method for the removal of monosaccharide in oligosaccharides production

摘要

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.
