Product Introduction
Precision Prebiotic for Gut Microecology
XOS (Xylooligosaccharides) is a premium prebiotic derived from plant biomass through enzymatic hydrolysis and membrane separation processes. It is characterized by its ultra-low effective dose and direct activation of Bifidobacteria. With a human digestibility rate of only 0.4%, it bypasses the upper GI tract intact, reaching the distal colon to selectively fuel beneficial microbiota. It serves as a foundational ingredient for formulations targeting gut health, bowel regularity, and microbiome balance.
Core Mechanism: Selective Fermentation → Bifidobacteria Proliferation → Microecological Balance → Improved Intestinal Function.
Core Advantages
1. Ultra-Low Effective Dose
Effective at just 0.7g/day. Ideal for low-fill formats (tablets, capsules, gummies).
2. Targeted Bifido Activation
Directly stimulates Bifidobacteriumabundance without disrupting overall flora structure.
3. Extreme Processing Stability
Stable at pH 2.5–11 and high temperatures (up to 180°C). Suitable for baking and extrusion.
4. Minimal Digestive Impact
Only 0.4% digested by human enzymes; full potency delivered to the colon.
5. High Purity Grades
Available up to 99% purity (XOS-99P) with negligible accompanying sugars.
6. Global Compliance
Approved as Novel Food (EU), GRAS (USA), and New Food Raw Material (China).
Gut Health Benefits
①Selective Prebiotic Effect: Significantly increases the abundance of Bifidobacteriumspecies, enhancing the gut barrier function.②Bidirectional Bowel Regulation: Effectively alleviates both constipation (by increasing stool bulk and frequency) and diarrhea (by balancing flora).
③Inhibition of Pathogens: Creates an acidic gut environment unfavorable for harmful bacteria (e.g., Clostridium), improving IBS and IBD conditions.
④Enhanced Nutrient Absorption: Promotes the synthesis of short-chain fatty acids (SCFAs), aiding in the absorption of minerals like calcium and magnesium.
⑤Synergy with Probiotics: Acts as a high-efficiency substrate ("food") for probiotic strains, improving their survival and colonization.
Recommended Applications
Dietary Supplements: Probiotic formulas, gut health capsules, synbiotic blends.
