Abstract: A method for producing an inositol derivative includes a step of reacting inositol and dextrin in the presence of cyclodextrin glucanotransferase to generate an inositol derivative in which a sugar is bonded to the inositol, and to obtain a solution containing the inositol derivative and the cyclodextrin glucanotransferase; and a step of removing the cyclodextrin glucanotransferase in the solution using an ultrafiltration membrane, in which a deactivation treatment of the cyclodextrin glucanotransferase in the solution is not performed.
