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&#xb0; C.-26&#xb0; C. for 20-30 hours with intermittent agitation.

Method for the removal of monosaccharide in oligosaccharides production

A method to control the distribution of the starch sugar's molecular weight by controlling of Ultra-low DE value during the reaction was invented. The method comprising blending starch with water to get starch slurry, and then mixing it with the 0.01%-0.03% of CaClbased on dried starch. The next step involves adjusting the pH of the starch slurry. A further step involves adding 0.03%-0.08% of heat-resisting &#x3b1;-amylases based on dried starch to the starch slurry described above. A further step involves controlling the production under optimal reaction conditions.
