Abstract

The present invention discloses a method of preparing oligosaccharide using biomass sugar as raw material. The method places a biomass sugar in a quartz tubular reactor, places the quartz tubular reactor at a temperature-controlled zone of a tubular thermal conversion reactor under the protection of nitrogen gas, controls a thermal conversion time, rapidly quenches a material to obtain an oligosaccharide precursor after thermal conversion ends, then dissolves by adding pure water and purifies through an inorganic ultrafiltration membrane, and finally obtain an oligosaccharide after drying.
