Fructooligosaccharide (FOS) 95% powder is a high-purity functional ingredient derived primarily from inulin-rich plants such as chicory root, artichokes, or onions through enzymatic hydrolysis. Chemically defined as a mixture of short-chain fructose polymers linked by β(2→1) glycosidic bonds, its molecular formula varies slightly depending on the degree of polymerization but generally approximates to C₁₈H₃₂O₁₆ for trisaccharides and C₂₄H₄₂O₂₁ for tetrasaccharides. The specific CAS number associated with commercial FOS mixtures is often cited as 68038-41-7, though individual components possess distinct identifiers. This white, crystalline powder boasts exceptional solubility in water and exhibits a mild sweetness, typically ranging between 30% to 60% that of sucrose, making it an ideal low-calorie sweetener substitute in various food formulations.
The primary application of FOS 95% lies in its potent prebiotic properties. As a non-digestible carbohydrate, it bypasses digestion in the upper gastrointestinal tract and reaches the colon intact, where it selectively stimulates the growth and activity of beneficial bacteria like Bifidobacteria and Lactobacilli. This mechanism supports digestive health, enhances mineral absorption, and boosts immune function. Consequently, it is widely utilized in the production of dietary supplements, infant formulas, probiotic foods, and functional beverages designed to improve gut microbiota balance. Beyond health benefits, FOS serves as a versatile texturizer and humectant in the food industry, improving mouthfeel and extending shelf life without altering flavor profiles significantly. It also acts as a fat replacer in low-fat products, maintaining creaminess while reducing caloric content. Due to its stability under heat and varying pH levels, manufacturers incorporate this 95% purity grade into baked goods, dairy products, and confectionery items. Furthermore, its safety profile is well-established globally, with regulatory approvals from agencies including the FDA and EFSA, ensuring its suitability for diverse consumer demographics seeking cleaner label solutions.
