Branched starches and branched starch hydrolyzates

摘要

The present invention provides a starch that includes at least one glucose polymer having greater than 4% alpha 1-6 glycosidic linkages. The present invention further provides a starch hydrolyzate that includes at least one glucose oligomer having greater than 4% alpha 1-6 glycosidic linkages. The starch and starch hydrolyzate present invention have improved aqueous solution stability and are less likely to retrograde than are solutions of unbranched linear starches or starch hydrolyzates. ;The present invention further provides a method of improving the aqueous solution stability of a starch or a hydrolyzate thereof, which method includes introducing one or more alpha 1-6 glycosidic linkages so as to branch one or more of the linear polysaccharides or hydrolyzates thereof. The method of the present invention also includes a method of improving the aqueous solution stability of amylose and amylose hydrolyzates by introducing one or more alpha 1-6 glycosidic linkages so as to branch one or more molecules of amylose or hydrolyzate thereof.
