We offer fructooligosaccharides (FOS) in two versatile formats:
- FOS Powder – free-flowing, low-moisture solid
- FOS Syrup – clear, viscous liquid
Both are produced via enzymatic transfructosylation of sucrose derived from sugar cane or hydrolysis of chicory root inulin, using food-grade enzymes—free from chemical synthesis, sulfites, or synthetic additives. With a mild sweetness (~30–50% of sucrose) and high solubility, FOS serves as a functional prebiotic fiber and clean-label sweetener enhancer.
Clinically shown to stimulate Bifidobacterium and Lactobacillus growth within days, FOS is one of the most researched prebiotics globally.
What Is FOS?
Fructooligosaccharides are short-chain fructose polymers (typically DP2–DP8) with a terminal glucose unit. Our FOS contains primarily 1-kestose (GF₂), nystose (GF₃), and fructofuranosylnystose (GF₄)—the most bioactive fractions for gut health.
The powder form is created by spray-drying the syrup under low-temperature conditions to preserve oligomer integrity, while the syrup retains natural humectant properties ideal for moist formulations.
Source Transparency: We offer both chicory-derived (high-purity, neutral taste) and sugar cane-derived (sweeter profile, sustainable origin) options—clearly labeled per batch.

FAQs
Q: Is FOS safe for children?
A: Yes! FOS is GRAS-approved and gentle for infants and toddlers.
Q: Can FOS replace sugar in beverages?
A: Yes—syrup provides 30-50% sweetness of sugar while adding prebiotic fiber.
Q: Does FOS cause bloating?
A: Start with small doses (≤5g/day) to allow gut adaptation.
Q: Is the syrup suitable for vegan products?
A: Absolutely! Both formats are plant-based and vegan-friendly.
Q: Do you offer private labeling?
A: Yes! Custom branding available for powder and syrup.
