Abstract
A method for fractionating dextrin, belonging to the technical field of food processing. In principle, the method for fractionating dextrin of the present invention is based on the fact that the dextrin is incompatible with polyethylene glycol in aqueous solution and a larger molecular weight of the dextrin results in more significant incompatibility with polyethylene glycol. Accordingly, the stepwise precipitation of dextrin components having a molecular weight from large to small may be realized by gradually increasing the concentration of polyethylene glycol by gradually adding polyethylene glycol to dextrin in aqueous solution.
