Prebiotic Science
Anneo Biotech — Dedicated Fructo-Oligosaccharides Manufacturer
Fosnia™ FOS
Understanding Fructo-Oligosaccharides (FOS)
Fructo-Oligosaccharides, commonly abbreviated as FOS, are short chains of fructose units that the human digestive system cannot break down in the small intestine. Instead, they travel to the colon largely unchanged, where they act as a selective food source for beneficial gut microbes.
This targeted fermentation in the colon is what classifies FOS as a prebiotic — an ingredient that selectively fuels the growth and metabolic activity of a healthy microbiome rather than delivering live organisms itself (which is how it fundamentally differs from a probiotic).
Anneo Biotech is a specialised Fructo-Oligosaccharides manufacturer, producing our proprietary Fosnia™ range through a controlled biofermentation process engineered for exceptional purity and batch-to-batch consistency.
“Prebiotic Science. Manufactured Reliably. Applied Practically.”
As formulators increasingly look to add soluble dietary fibre and gut-health positioning to their products, having a manufacturer who understands both the micro-science of FOS and the practical realities of industrial formulation has become indispensable — and that is the partnership Anneo delivers.

Purpose-Built FOS Manufacturing Process
Anneo manufactures directly rather than brokering third-party inventory. This provides our commercial partners with end-to-end quality assurance and batch traceability.
- Consistent FOS Content: HPLC-verified active prebiotic content batch to batch
- Dual Format Availability: Liquid syrups (L-Series) and high-solubility powder (P-Series)
- Four Distinct Grades: Covering wide active concentrations from 55% to 95%
- Formulation Assistance: Technical guidance on pH, heat stability, and sweetness profiles
- Regulatory Dossier: Complete CoA, Technical Data Sheets (TDS), and specification documents
- Scalable Supply Chain: Dependable volumes from R&D pilots to commercial container loads
- Application Samples: Fast-turnaround sampling to fast-track formulation development
Traceable & Tested
Every batch is certified for microbiological purity and degree of polymerisation.

Target Formulation Sectors
Where Fructo-Oligosaccharides Are Used
Gut-Health & Digestive Wellness
Acts as a selective nutrient for Bifidobacteria and Lactobacilli, supporting short-chain fatty acid (SCFA) production and intestinal barrier integrity.
Fibre-Fortified Beverages & Dairy
Imparts clean mouthfeel, replaces sucrose without crystalline off-notes, and maintains clarity in acidified RTD beverages, yogurts, and cultured milks.
Bakery & Confectionery Products
Functions as a bulking agent, moisture retainer, and partial sugar replacer in nutrition bars, functional gummies, jellies, and baked goods.
Infant & Early-Life Nutrition
Mimics oligosaccharide profiles to cultivate favourable early microbiome colonisation, supporting immune maturation and stool softening in specialized formulas.
Synbiotic Blends Paired with Probiotics
The ideal prebiotic companion in dry blends, sachets, capsules, and drink powders, providing the exact substrate necessary to sustain probiotic survival post-ingestion.
