Polydestrose is a highly branched, randomly bonded glucose polymer with an average DP of 12, ranging from 2 to 120. The molecule contains all possible combinations of α- and β-linked 1→2, 1→3, 1→4,and 1→6 glycosidic linkages, though the 1→6 (both α and β) predominates. Due to its complex structure, PDX is not hydrolyzed by mammalian digestive enzymes in the small intestine, passing intact into the colon, in which it is gradually and partly fermented by the endogenous microbiota and the remainder, approximately 60%, is excreted in the feces. Sugar free polydextrose is reducing sugar ≤0.3% polydextrose.
