Fibredex®Resistant dextrin
The invisible fibre. Clear, neutral and stable through acid, heat and UHT, with glycaemic evidence from 37 clinical trials.
What it is
Resistant dextrin starts as ordinary starch and ends as a branched molecule that amylase cannot digest. It brings no taste, no colour, no haze and almost no viscosity, which makes it the fibre you add when the product must not change.
Three steps from source to powder
Corn or tapioca starch
Heat and a trace of acid rearrange the starch into branched chains with linkages digestion cannot break
Enzyme treatment removes the digestible fraction, then purification and spray-drying
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
Adds nothing sensory, which is the point. Its prebiotic effect needs a higher dose than the oligosaccharides, so pair it with XOS or GOS when the claim matters.
Where it works, and the evidence
The highlighted stops are where Resistant dextrin is active along the gut. Below, the numbers behind the claims, with the study each one comes from.
Attenuated post-meal glucose and insulin response when taken with a meal, across 37 trials
Livesey and Tagami, 2008Bifidobacteria up 38% and greater stool bulk in healthy adults
ADM clinical study, 2018Well tolerated at fibre-fortifying doses in young children
Randomised trial, 2022What you can say, where
Resistant maltodextrin and dextrin recognised since June 2018
Counts as fibre; qualifies for the sugar-replacer glycaemic claim when it replaces sugar
Added to the nutraceutical regulations as a soluble fibre and prebiotic in 2022

Pairs well with
No fibre in this family works alone for long. These are the pairings where Resistant dextrin 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.
Resistant dextrin keeps a clear acidic drink clear; XOS adds a bifidogenic claim at a dose that fits one bottle.
