Xylooligosaccharide Specifications

When sourcing xylooligosaccharides (XOS) in bulk, choosing the right Xylooligosaccharide Specifications is one of the most critical decisions a procurement manager, R&D formulator, or ingredient importer will make. The wrong grade can affect product performance, regulatory compliance, and formulation stability.

At BSH Ingredients, we supply a comprehensive range of xylooligosaccharide specifications designed to meet the diverse needs of food manufacturers, dietary supplement brands, animal feed producers, beverage companies, and more. With six distinct XOS grades available: from high-purity 95% XOS powder to versatile liquid and syrup forms, we give bulk buyers the flexibility to source exactly what their application demands.

This guide covers everything you need to know about our full XOS product line: what each specification is, how they compare, which grade is best suited to your industry, and how to get started with a bulk order or sample request.

What Are Xylooligosaccharides?

Xylooligosaccharides are prebiotic dietary fibers derived primarily from corncobs through a process of enzymatic hydrolysis. They consist of short-chain xylose units linked by β-1,4 glycosidic bonds and are widely recognized for their ability to selectively stimulate the growth of beneficial gut bacteria, particularly Bifidobacterium species.

When we refer to XOS specifications, we are talking about several key parameters that define a product’s grade, purity, and suitability for different applications:

  • XOS content (%): The concentration of actual xylooligosaccharide chains in the product, typically expressed as a percentage of dry weight
  • Physical form: Powder, syrup, or liquid
  • Grade: Food grade or feed grade
  • Moisture content: Critical for powder stability and shelf life
  • pH range: Important for beverage and dairy applications
  • Appearance: Color, texture, and particle size
  • Solubility: How readily the product dissolves in water or other media
  • Degree of polymerization (DP): The chain length of xylose units, typically DP2-DP7 for most commercial XOS

Understanding these parameters allows buyers to match the right XOS specification to their specific formulation requirements, regulatory environment, and cost targets.

FAQs

What are the main xylooligosaccharide specifications available on the market?

Xylooligosaccharide (XOS) is available in several specifications designed for different industries and formulation needs. The most common options include Food Grade XOS Powder at 95%, 70%, and 35%; Feed Grade XOS Powder at 35%; and liquid forms such as XOS 70% and 80%. These variations differ mainly in purity, sugar composition, and suitability for application. Higher purity grades are typically used in dietary supplements and premium products, while lower concentrations are more cost-effective for large-scale food and feed applications.

What is the difference between XOS 95%, 70%, and 35%?

The difference between XOS 95%, 70%, and 35% lies in the active xylooligosaccharide content and the proportion of residual sugars. XOS 95% offers high purity with minimal monosaccharides, making it suitable for supplements and high-end formulations. XOS 70% provides a balanced composition that works well in beverages and dairy products, offering both functionality and cost efficiency. XOS 35% contains a lower concentration of active XOS but is more economical, which makes it a practical choice for bakery products, bulk food production, and feed applications.

Which XOS specification is best for beverages?

For beverage applications, XOS Liquid 70% or 80% is generally the most practical choice because it dissolves easily and integrates smoothly into liquid processing systems without dust or additional mixing steps. For manufacturers working with powder-based formulations, XOS 70% powder is also widely used, as it offers good solubility and a balanced cost-performance ratio for functional beverages and drink mixes.

Which XOS grade is recommended for dietary supplements?

In dietary supplements, XOS 95% powder is often preferred for its high purity and low sugar content, which support clean labeling and consistent dosing. It is commonly used in capsules, tablets, and powder sachets where precise formulation is required. From a formulation standpoint, this grade enables manufacturers to more clearly highlight prebiotic benefits. Typical daily supplement dosage ranges from 1 to 3 grams, depending on the product positioning.

How stable is xylooligosaccharide during processing?

Xylooligosaccharide is known for its strong stability under common food processing conditions. It remains stable under heat treatments such as pasteurization and baking, and it performs well across a wide pH range, typically from 2.5 to 8. This makes it suitable for acidic beverages as well as neutral food systems. In addition, XOS is resistant to digestion in the upper gastrointestinal tract, which allows it to reach the colon and function effectively as a prebiotic.

What is the difference between XOS powder and XOS liquid?

The main difference between XOS powder and liquid lies in handling and application convenience. Powder forms are easier to store, have a longer shelf life, and are well-suited for dry blends and supplement formulations. Liquid XOS, on the other hand, is easier to incorporate into beverage production and liquid food systems, as it dissolves quickly and eliminates dust during processing. Functionally, both forms provide the same prebiotic benefits, so the choice depends mainly on production requirements.

How do I choose the right XOS specification for my product?

Choosing the right XOS specification depends on your product type, formulation goals, and cost considerations. XOS 95% is typically selected for supplements and premium products where purity is important. XOS 70% is widely used in beverages and dairy products because it offers a good balance between performance and cost. XOS 35% is more suitable for cost-sensitive applications such as bakery or large-scale food production, while liquid XOS is preferred for liquid processing systems. In most cases, manufacturers test different specifications during product development to determine the best fit.

What is the typical packaging and shelf life of bulk XOS?

Bulk xylooligosaccharide is usually supplied in powder form in 25 kg fiber drums or bags, while liquid XOS is packed in drums or IBC containers for large-scale handling. The typical shelf life for XOS powder is around 24 months when stored in a cool and dry environment, while liquid forms generally have a shelf life of 12 to 18 months. Proper storage conditions are important to maintain product quality and stability during transportation and long-term storage.
