DESCRIPTION

Polydextrose occurs as an off-white to light tan solid. It is a randomly bonded polymer prepared by the condensation of a melt that consists of approximately 90% d-glucose, 10% sorbitol, and up to 1% citric acid and/or up to 0.1% phosphoric acid on a weight basis. The 1,6-glycosidic linkage predominates in the polymer, but other possible bonds are present. The product contains small quantities of free glucose, sorbitol, and d-anhydroglucoses (levoglucosan), with traces of citric acid or phosphoric acid. It may be partially reduced by transition metal catalytic hydrogenation in an aqueous solution. It may be neutralized with any food-grade base and decolorized and deionized for further purification. It is very soluble in water.
