Galacto-oligosaccharides (GOS)
About Galacto-oligosaccharides (GOS)
Galactooligosaccharides are produced from lactose using the action of β-galactosidase enzymes. They are mixtures of oligosaccharides consisting of galactose molecules linked to the galactose moiety of a lactose molecule via β(1-4), β(1-6), or β(1-3) bonds.

Main Functions
Mimics Breast Milk Immunity: This is GOS's most core attribute.
Immune Barrier: Can form a protective film on the intestinal wall, preventing pathogenic bacteria from binding to the intestinal mucosa.
Reduces Allergies.
Potent Probiotic Proliferation: GOS is a specialized "fuel" for Bifidobacteria and Lactobacillus. Improves intestinal motility and relieves constipation.
Enhanced Mineral Absorption: The acidic environment generated by GOS fermentation in the gut effectively promotes the absorption of calcium, magnesium, iron, and zinc.
Mood Regulation (Gut-Brain Axis): Has potential as a "psychobiotic," helping to lower cortisol levels and improve anxiety and stress by modulating the gut microbiota.
Applications
- Infant Formula: The combination of FOS and GOS is the standard in European and American formulas for mimicking 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.
