Audited Supplier Polydextrose is a polysaccharide food ingredient composed of randomly bonded glucose polymers, including about 10% of sorbitol and 1% of citric acid. Polydextrose is a bulking agent, stabilizer, thickener, and humectant. It is a soluble prebiotic fibre, applied as a replacer of sugar, starch, and fat, and for calorie reduction. The WHO Joint Expert Commission for Food Additives (JEFCA) in 1987 specified no ADI for polydextrose. In the EU it has the food ingredient number E 1200 and can be added at "quantum satis." The FDA approved it in 1982. The caloric value of 1 kcal per gram is widely accepted.
Polydextrose is highly water soluble, 80% at ambient temperature. The viscosity of a 70% solution at 25°C is about 1800 mPa s. Polydextrose has interesting properties from a food technologist's viewpoint:
•The sweetness is very low, just about 5% compared to sucrose
Polydextrose is thermally stable; it is a glass, not crystalline and softens at 90-110°C. The glassy structure greatly helps in the prevention of sugar crystallization and cold flow in candies
Polydextrose may retard starch retrogradation in waffles
Depending on the purification grade there is some acid side taste, primarily for the most economic grades
Polydextrose is hygroscopic. Therefore with polydextrose in cream recipes being not absolutely dry, some blocking of pump heads due to hard residues will occur
In baking the browning (Maillard reaction plus caramelization) is low, especially with the more purified grades
Polydextrose is just slightly laxative with tolerable doses of 50-90 g/day
Polydextrose may be applied to improve the nutritional profile of products
•Low caloric value of 1 kcal/g
Polydextrose is suitable for claims as sugar free, no added sugar, or reduced in sugar
Low glycaemic index and load, the reported GI values are 7 or lower, suitable in wafers and waffles for diabetics
In moisture-containing systems, a partial fat replacement is possible
Polydextrose is a soluble prebiotic fibre
Polydextrose is noncariogenic (tooth-friendly)
