Inulin vs FOS

Related fructan fibres with different chain-length distributions — choose based on formulation function, not only the prebiotic label.

FOS and inulin are related fructan fibres with overlapping chemistry but different chain-length distributions. FOS generally contains shorter-chain fructooligosaccharides, while commercial chicory inulin contains a broader distribution extending to longer chains. The choice depends on fibre targets, texture needs, sensory profile, dose tolerance, and application format.

FactorInuluxe™ InulinFOS
Chain length / DPBroad distribution including longer chainsPredominantly shorter-chain fructooligosaccharides
Fermentation profileDepends on DP; longer chains generally ferment more graduallyGenerally faster fermentation of shorter-chain fractions
ToleranceDepends on dose and individual sensitivityHigher intakes may cause GI discomfort in some individuals
SolubilityHigh; formulation-dependentHigh
SweetnessGenerally neutralMild sweetness
TextureCan contribute body, creaminess and fat-mimetic functionality, depending on DP and use levelLimited structural contribution
Fibre enrichmentSuitable for higher fibre inclusion depending on formulationOften used at lower inclusion levels because of its sensory and functional profile
Typical applicationsBeverages, dairy, bakery, bars, supplementsBeverages, synbiotics, supplements and other low-dose formats

When to choose Inuluxe™ inulin

Choose Inuluxe™ when you need fibre enrichment + prebiotic fibre contribution + formulation functionality — especially body, creaminess, mouthfeel support, and neutral taste in reduced-sugar or reduced-fat systems.
