1. How Do We Solve Your Standardization & Testing Challenges?

Reliable quality control is non-negotiable. We use validated High-Performance Liquid Chromatography (HPLC) methods that comply with GB/T 23528.3-2025 to guarantee XOS content. Our testing protocols use cation-exchange columns with RI detection for precise quantification of individual oligomers (xylobiose to xylohexaose). Alternatively, acid hydrolysis followed by HPLC analysis converts XOS into xylose for total content determination. For complex health food matrices, we use pre-column derivatization with PMP and UV detection at 254nm—a method standardized by food safety authorities for accuracy and precision. Each shipment includes a comprehensive Certificate of Analysis (CoA) with chromatographic data, heavy metals, and microbiological testing. Consequently, you can validate incoming material quickly and meet regulatory requirements with total confidence.

2. What Is XOS, and Why Is Our Production Process Superior?

Xylo-oligosaccharides are short-chain oligomers (2-7 xylose units linked by β-1,4 bonds) derived from plant hemicellulose—typically corncob and sugarcane bagasse. Unlike C6-based prebiotics, XOS delivers 10-20 times stronger bifidogenic activity than FOS, GOS, or IMO, selectively stimulating beneficial gut bacteria at doses as low as 0.7-1.4g/day.

We source our raw materials from certified, sustainable agricultural bases and use a validated enzymatic hydrolysis process followed by membrane filtration and chromatographic purification. Unlike suppliers relying on crude acid hydrolysis, our process yields a white to light yellow free-flowing powder with consistent purity and minimal residual monosaccharides. Our production facilities are cGMP-compliant, with fully automated lines ensuring batch-to-batch consistency from raw material feeding to final packaging.

3. Matching the Right Grade to Your Product Line

Your application is unique. We offer XOS in targeted grades:

• 95% High-Purity Grade: Ideal for premium dietary supplements, clinical nutrition, and formulations requiring maximum activity at minimal inclusion rates. Contains ≥65% XOS2-4 for rapid fermentation and efficacy.

• 70% Standard Grade: Suitable for functional foods, beverages, dairy products, and baked goods where cost-efficiency and versatility are priorities.

• 35% Food Grade: Designed for general food applications, animal nutrition, and feed formulations.

Tell us your product format, dosage target, and market positioning. We will recommend the most cost-effective and technically suitable grade.

4. Solving Your Formulation & Stability Problems

A common frustration with prebiotics is their instability under heat or acidic conditions. XOS solves this. It remains stable at 100°C for 1 hour across pH 2.5-8.0, making it suitable for pasteurization, baking, and acidic beverages. It also withstands high-pressure processing (HPP) up to 600 MPa combined with thermal treatment, preserving its integrity in functional beverages. The powder has a mildly sweet taste (30-50% of sucrose), allowing sugar reduction without artificial sweeteners. Its low hygroscopicity (retains >95% weight at 75% humidity) ensures excellent flowability and shelf stability.

5. Eliminate Inventory Waste with Proper Storage Guidelines

Our XOS powder is stable when stored correctly. First, keep it in a cool, dry place (15-25°C) away from direct sunlight and moisture. Next, store in tightly sealed, airtight containers to prevent moisture absorption. Under these conditions, the product maintains its full activity for 24 months from the date of manufacture. This extended shelf life allows you to purchase in cost-effective bulk quantities without fear of degradation.

Stop Compromising on Prebiotic Efficacy. Start Using a Reliable, High-Purity XOS Source.

We have eliminated the guesswork and risk from sourcing Xylo-oligosaccharide. Our commitment to validated HPLC testing, cGMP manufacturing, and transparent documentation is designed to make your procurement and formulation process effortless. We are not just a raw material vendor; we are your partner in creating science-backed gut health products that consumers trust.
