Our mannooligosaccharides (MOS) are short-chain oligosaccharides composed primarily of mannose units, produced through controlled enzymatic hydrolysis of glucomannan sourced from konjac root (Amorphophallus konjac) or locust bean gum (carob). With ≥85% MOS content (dry basis), this soluble fiber acts as a non-digestible prebiotic that supports gut microbiota balance and exhibits unique anti-adhesion properties against harmful bacteria such as Salmonella and E. coli.
Unlike fermentable fibers like FOS or GOS, MOS works primarily in the upper GI tract by binding to lectin receptors on pathogenic microbes—preventing their colonization and promoting natural clearance. This dual mechanism makes MOS valuable in both human nutrition and premium animal feed applications.
What Is MOS?
Mannooligosaccharides are derived from mannans—natural polysaccharides found in plant cell walls. Our MOS powder is manufactured using food-grade endo-β-mannanase enzymes under mild conditions, followed by ultrafiltration and spray-drying—without acid, alkali, solvents, or synthetic additives.
We offer two botanical sources to meet formulation and labeling needs:
- Konjac-based MOS: High purity, neutral taste, ideal for human supplements
- Locust Bean (Carob)-based MOS: Traditional source, widely accepted in pet nutrition
Both are certified non-GMO, and free from common allergens.
Key Functional & Health Benefits
- Pathogen exclusion: Binds type-1 fimbriated bacteria via mannose-specific adhesion
- Prebiotic support: Indirectly promotes beneficial flora by reducing pathogen load
- Immune modulation: Enhances gut-associated lymphoid tissue (GALT) activity
- High stability: Resists heat, pH changes, and digestion—effective throughout GI tract
- Low fermentation: Minimal gas production vs. other prebiotics (reduced bloating risk)
- Non-caloric & non-glycemic: Suitable for diabetic, keto, and low-FODMAP diets
Note: MOS is not significantly fermented by colonic bacteria, making it distinct from traditional prebiotics like inulin—but highly complementary in synbiotic formulations.

Applications
Human Nutrition
- Dietary Supplements: Standalone MOS or combined with probiotics (synbiotics) for gut-immune support
- Functional Foods: Added to bars, cereals, and beverages for “immune health” claims
- Medical Nutrition: Used in enteral formulas for patients with dysbiosis or infection risk
- Low-FODMAP Products: Well-tolerated alternative to high-fermentation fibers
Animal & Pet Nutrition
- Pet Food (dogs/cats): Enhances stool quality, reduces pathogens, supports immunity
- Livestock Feed: Natural alternative to antibiotics in poultry, swine, and aquaculture
- Equine & Ruminant Diets: Improves hindgut health without disrupting fermentation
