Abstract
Provided is a method that enables industrially efficient production of an esterified polysaccharide product. A method for producing an esterified polysaccharide product, the method including reacting a polysaccharide-containing biomass, a basic ionic liquid with a pKa of a conjugate acid of an anion from 2 to 19 as a calculated value in a vacuum, and an esterifying agent using a kneader equipped with a shear force application mechanism. A cation constituting the basic ionic liquid is preferably one selected from the group consisting of an imidazolium cation, a pyridinium cation, and a tetraalkylammonium cation.
