摘要：
Method for preparing a branched glucan having a chain comprising a plurality of glucose units linked by alpha 1,4-glycoside bonds and a plurality of side-groups linked to said chain via another type of glycoside bonding, which side-groups comprise one or more glucose units, the method comprising contacting a glucose source with a polysaccharide - which polysaccharide is a glucan comprising a plurality of glucose units linked by alpha 1,4-glycoside bonds and is essentially linear or branched to a lesser extent than the branched glucan that is to be prepared - in the presence of an acid catalyst under polycondensation conditions, thereby forming the branched glucan.
