Purified macromolecular amyloses are prepared by debranching the branched fraction present in starch, namely amylopectin, with the employment of alpha-1,6-glucosidases after gelatinizing the starch by heating, freezing the resultant, thawing the frozen product, heating the thawed product to a temperature lower than 70 DEG C, eluting the low molecular amyloses, and then removing the retrograded starch thus formed in order to purify the macromolecular amyloses. |
