Introduction
POLYDEXTROSES
Prepared at the 51st JECFA (1998) and published in FNP 52 Add 6 (1998) superseding specifications prepared at the 44th JECFA (1995), published in FNP 52 Add 3 (1995). An ADI "not specified" was established at the 31st JECFA in 1987.
SYNONYMS Modified polydextroses; INS No. 1200
DEFINITION Randomly bonded condensation polymers of glucose with some sorbitol end-groups, and with citric acid or phosphoric acid residues attached to the polymers by mono or diester bonds. They are obtained by melting and condensation of the ingredients which consist of approximately 90 parts D-glucose, 10 parts sorbitol and up to 1 part citric acid or 0.1 part phosphoric acid. The 1,6-glucosidic linkage predominates in the polymers but other linkages are present. The products contain small quantities of free glucose, sorbitol, levoglucosan (1,6-anhydro-D-glucose) and citric acid and may be neutralized with any food-grade base and/or decolourized and deionized for further purification. The products may also be partially hydrogenated with Raney nickel catalyst to reduce residual glucose. Polydextrose-N is neutralized Polydextrose.
C.A.S. number 68424-04-4
Assay Not less than 90.0% of polymer on the ash-free and water-free bases
DESCRIPTION White to light tan-coloured solid. Polydextroses dissolve in water to give
clear, colourless to straw-coloured solutions
FUNCTIONAL USES Bulking agent, humectant, stabilizer, thickener
