Polydextrose
Polydextrose is a manufactured polysaccharide prepared by acid catalyzed vacuum
thermal polymerization of glucose and sorbitol. The average DP is 12 with
range of molecular weight between 162 and 20,000. AOAC method 2000.1112 incorporates
hot water extraction and ultrafiltration. The filtrate is treated with a mixture
of isoamylase, amylogluco-sidase, and fructanase. Polydextrose standards are
treated in similar manner, and used to quantify a high-molecular-weight fraction of
polydextrose using HPAEC-PAD.
