Description
A long-chain fructooligosaccharide preparation with degree of polymerization in the 9 to 60 range, isolated from chicory inulin. Provides slower colonic fermentation and lower flatulence potential than short-chain FOS.
White free-flowing powder with very low sweetness. Soluble in water; mildly viscous in solution.
We supply food-grade Long-Chain FOS from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include neat Long-Chain FOS 95%, blended systems combining long-chain and short-chain FOS, and instant-soluble agglomerated grades.
Bulk and reduced-MOQ shipments. Batch-level COA covering FOS content, DP distribution, free sugars, heavy metals, and microbiology.
Introduction
Fructooligosaccharides span a chain-length distribution from short (DP 2 to 8) through long (DP 9 to 60 or higher). The long-chain fraction is selectively isolated from chicory inulin and provides distinct functional and physiological properties.
Long-chain FOS ferments more slowly in the colon than short-chain FOS, distributing fermentation activity further along the colon and reducing gas production in the proximal colon. This produces better gastrointestinal tolerance at high doses.
The product is positioned in infant nutrition, often blended with short-chain galactooligosaccharides at a 9:1 GOS:FOS ratio that mimics the prebiotic profile of human milk oligosaccharides. The combination is approved for infant formula in the EU and other regulated markets.
Adult supplement and functional-food positioning emphasizes microbiome support and digestive comfort, particularly at doses above 5 grams daily where short-chain FOS would produce significant flatulence.
Where it is used
- Infant nutrition in approved markets (often combined with short-chain galactooligosaccharides)
- Premium prebiotic supplements
- Functional foods for digestive comfort
- Yogurts and dairy products
- Meal-replacement shakes
- Bars and snacks with prebiotic positioning
- Co-formulation with probiotics in synbiotic products
- Elderly nutrition focused on microbiome support
