Xylo-oligosaccharides (XOS)

Core Functional Properties

● Ultra-Low Calorie

XOS cannot be decomposed and absorbed by human salivary, gastric and small intestinal digestive enzymes, with a calorific value of only approximately 0.8 kcal/g, far lower than sucrose and most oligosaccharides. It is the preferred raw material for sugar-free and low-calorie healthy food.

● Ultra-High Stability with Strong Acid & High Temperature Resistance

Dissolves rapidly in both cold and hot water to form clear and transparent solution; maintains stable molecular structure without degradation or precipitation under low-pH acidic environments, high-temperature sterilization above 120℃, baking and boiling processes, with much higher processing tolerance than FOS and GOS.

● Zero Glycemic Response, Insulin-Independent

Hardly absorbed in the human small intestine, causing no blood glucose fluctuations after ingestion and requiring no insulin for metabolism. Safe for diabetics, patients with impaired glucose tolerance and weight control groups.

● Superior Prebiotic Effect (Core Differentiating Advantage)

Reaches the colon intact with only a tiny dosage, specifically stimulates massive proliferation of Bifidobacterium and Lactobacillus, and inhibits colonization of putrefactive bacteria and pathogenic bacteria. Its flora boosting efficiency is 10~20 times that of FOS, and trace addition can significantly optimize intestinal microecology.

● No Adverse Moisture Retention Side Effects

Non-hygroscopic in nature, will not cause baked goods to absorb moisture, soften, agglomerate or dampen. It does not affect the crispness and shelf life of flour products and pastries, resulting in fewer restrictions in processing application.

● Low Caries Risk

Oral microorganisms cannot ferment XOS to produce organic acids, thus avoiding enamel corrosion and effectively reducing caries incidence. Suitable for children’s snacks and oral care products.

Physiological Regulatory Functions

As a highly active prebiotic dietary fiber, XOS exerts multiple physiological regulatory effects in the human intestinal tract:

● Intestinal Health:

Fermented by intestinal flora to generate abundant short-chain fatty acids, lower colonic pH value, accelerate intestinal peristalsis, soften stool and relieve constipation; strengthen the intestinal epithelial barrier and reduce risks of intestinal leakage and chronic inflammation

● Weight Management:

Creates gentle satiety in the stomach to delay gastric emptying and prevent overeating; short-chain fatty acids participate in body metabolism to assist fat metabolism optimization

● Glycolipid Metabolism Regulation:

Fully unabsorbed in the small intestine to stabilize postprandial blood glucose; binds bile acids in the intestinal tract for excretion, helping reduce triglycerides and low-density lipoprotein to maintain blood lipid health

● Mineral Absorption:

Acidifies the intestinal microenvironment to improve dissociation of calcium, iron, zinc, magnesium and other mineral ions, elevate trace element absorption rate and support bone development

● Immunity Regulation:

Activates immune cells in gut-associated lymphoid tissue relying on stable intestinal flora and intact intestinal mucosa, boosting overall body immunity starting from the intestinal tract

Product Applications
