Fibredex®Polydextrose
The bulking fibre for sugar and calorie reduction. Body and mouthfeel without sucrose, at 1 kcal per gram and the widest tolerance window in the family.
What it is
Polydextrose is a randomly bonded glucose polymer, built so that human enzymes cannot take it apart. It dissolves like sugar, bulks like sugar and carries flavour like sugar, with a quarter of the calories and none of the sweetness.
Three steps from source to powder
Glucose with a little sorbitol and a citric acid catalyst
Heated under vacuum so the glucose links in random, highly branched chains that digestion cannot follow
Neutralised, purified and dried to a powder or supplied as a syrup
How it behaves in the pot
Six things a formulator asks before anything else. Five bars is a lot of that property, one bar is a little, and neither is good or bad on its own. It depends on the food.
Typical values for food grades. Every FIBREDEX® lot ships with its own COA and specification.
Fits best in
Handle with care
Hygroscopic above 60% humidity and slightly tart at very high use. Its microbiome effect is a general shift rather than a bifidogenic spike, so blend with XOS or GOS where a prebiotic claim is needed.
Where it works, and the evidence
The highlighted stops are where Polydextrose is active along the gut. Below, the numbers behind the claims, with the study each one comes from.
Lower energy intake at the next meal, dose-linked, across randomised trials
Ibarra et al, meta-analysis 2015Shifts the gut microbiota and improves bowel habit in healthy adults
Costabile et al, 2012Lower post-meal blood glucose rise when it stands in for sugar, under the EU generic sugar-replacer claim
EU Reg. 432/2012What you can say, where
Recognised since June 2018, at 1 kcal per gram
Counts as fibre; qualifies for the sugar-replacer glycaemic claim when it replaces sugar
Named in the prebiotic schedule of the Health Supplements and Nutraceuticals regulations

Pairs well with
No fibre in this family works alone for long. These are the pairings where Polydextrose does its best work, and what the partner brings.
Polydextrose brings bulk and body at 1 kcal per gram; resistant dextrin brings clarity and acid stability. High fibre, low viscosity, low calories.
Inulin for creaminess and fat reduction, polydextrose for sugar bulk and freeze-point control. Splitting the load keeps tolerance in range.
