Fructooligosaccharides (FOS)
About Fructooligosaccharides (FOS)
Fructooligosaccharides are produced from sucrose using the catalytic action of fructosyltransferase enzymes. They are mixtures of oligosaccharides consisting of 1 to 3 fructose (F) units linked by β(2→1) glycosidic bonds to the fructose moiety of a sucrose (G-F) molecule, resulting in kestose (GF2), nystose (GF3), and fructofuranosylnystose (GF4).

Main Functions
Potent Prebiotic: FOS is a "superfood" favored by probiotics.
Targeted Proliferation: It reaches the large intestine intact and highly specifically promotes the explosive growth of Bifidobacteria and Lactobacillus.
Inhibits Bad Bacteria: By producing short-chain fatty acids (SCFAs) that lower the intestinal pH, it inhibits pathogenic bacteria like Salmonella.
Improves Constipation & Digestion: FOS is a soluble dietary fiber that increases intestinal osmotic pressure, softening stools by allowing them to absorb more water, significantly shortening the defecation cycle.
Promotes Mineral Absorption: The acidic environment produced by fermentation can increase the solubility of minerals like calcium and magnesium, helping prevent osteoporosis.
Regulates Blood Lipids: Intake of FOS may help lower serum cholesterol and triglyceride levels, offering auxiliary benefits for cardiovascular health.
Applications
- Infant Formula: The combination of FOS and Galactooligosaccharides (GOS) is the standard in European and American formulas for mimicking Human Milk Oligosaccharides (HMOs).
- Fortified Foods & Beverages: Ideal ingredient for meal replacement powders and nutrition bars.
- Dairy Products: In functional yogurts, it provides sweetness and acts as a prebiotic. A perfect partner for yogurt and lactic acid bacteria drinks.
- Dietary Supplements: Often added as a "substrate" or "energy source" in common probiotic capsules and powders.
- Animal Feed.
- Health Products: Prebiotic capsules, etc.
