Abstract
The invention relates to the field of poly-and oligosaccharides and their nutritional effects. In particular, it relates to the application of α-glucanotransferases in methods for preparing dietary fibers, including prebiotic oligosaccharides, and to novel oligosaccharides obtainable thereby. Provided is a method for producing a mixture of gluco-oligosaccharides having one or more consecutive (α1→6) glucosidic linkages and one or more consecutive (α1→4) glucosidic linkages, comprising contacting a poly- and/or oligosaccharide substrate comprising at least two (α1→4) linked D-glucose units with an α-glucanotransferase capable of cleaving (α1→4) glucosidic linkages and making new (α1→4) and (α1→6) glucosidic linkages. Also provided are (isolated) gluco-oligosaccharides obtainable thereby, and their application in nutritional and cosmetic compositions.
