Abstract
A method by which a cellooligosaccharide can be produced inexpensively at high percentage yield is provided. In the method for producing a cellooligosaccharide according to an embodiment, at least one primer selected from the group consisting of glucose, cellobiose, and derivatives in which anomeric positions of glucose and cellobiose are modified and sucrose are subjected to, in the presence of phosphoric acid, actions of sucrose phosphorylase and cellodextrin phosphorylase. In this case, in the reaction system, the concentration of phosphoric acid is set to 3 mol/m3 or more and 120 mol/m3 or less.
