<p>Provided are a dry and stable active esterified polysaccharide which does not generate insoluble matter when dissolved in water, and a production method that enables the commercial production of active esterified polysaccharides displaying such qualities. The method for producing active esterified polysaccharides involves subjecting an electrophilic compound and polysaccharides that contain a carboxy group to an esterification reaction, bringing the generated active esterified polysaccharides into contact with a polyvalent carboxylic acid, and then precipitating and collecting the resulting active esterified polysaccharides.</p> |
