Chitosan Global supplies Mushroom (fungal-origin) Chitosan Oligosaccharide as a non-shellfish alternative to conventional COS, available in Food, Nutraceutical, and Industrial grades with sample, standard, and bulk quantities. Current verified specifications: DDA 95%+ and molecular weight below 1 kDa. Before sourcing any COS material, verify the actual specification sheet and COA — “chitosan oligosaccharide” alone doesn’t tell you enough to evaluate a raw material.

Material Snapshot

Always confirm these figures against the current product page and batch-specific COA before finalizing an order — specifications can be updated between production runs.

How to Evaluate a Mushroom COS Supplier

“Chitosan Oligosaccharide” is a category, not a single material. Serious buyers should compare actual documentation, not supplier marketing claims.

Not All COS Is the Same

Two materials both labeled “Chitosan Oligosaccharide” can differ meaningfully in molecular weight distribution, degree of polymerization, DDA, purity, residual processing materials, and solubility behavior — all of which affect how the material performs in your application. Source (fungal vs. shellfish vs. other) is one factor among several, not a substitute for checking the actual specification sheet. For the underlying COS chemistry and how these variables relate to each other, see the complete Mushroom Chitosan Oligosaccharide guide.

Sample-First Procurement Path

1. Identify your application
2. Define your required specification (MW, DDA, grade, purity)
3. Review the COA against that specification
4. Order a laboratory sample
5. Run your own formulation or compatibility testing
6. Confirm the grade meets your requirements
7. Request a commercial quote
8. Scale to production

Sample evaluation reduces both formulation and procurement risk before you commit to volume. A successful sample test is a strong signal, not a guarantee that results will scale identically to full production.

COA and Documentation

Before committing to bulk quantities, request and review the current Certificate of Analysis. Depending on grade, this may include molecular weight, DDA, moisture, ash, purity, solubility, and — for food, nutraceutical, or microbiologically sensitive applications — relevant microbiological and heavy-metal data. Confirm with our team exactly which parameters are included on the current COA for your intended grade before assuming a specific test is covered.

What to Send When Requesting a Quote

To get an actionable quote quickly, include:

• Intended application
• Required grade (food, nutraceutical, or industrial)
• Quantity needed
• Destination
• Required molecular weight range, if specific
• DDA requirement, if applicable
• Purity requirement
• Documentation needed (COA, SDS, additional testing)
• Whether you need a sample first or are ready for commercial quantity
• Desired delivery schedule

Applications — Brief Overview

Functional foods and beverages: COS’s water solubility and low molecular weight support use in powder blends, functional drinks, and clean-label formulations. See Mushroom COS for Functional Foods for the full application detail.

Drug-delivery research: Low-molecular-weight, water-soluble COS is investigated in pharmaceutical formulation research. See Mushroom COS for Drug Delivery for mechanisms and evidence.

Other applications: Agriculture (biostimulant and plant-defense research), cosmetics (hydration and film-forming formulations), and industrial/biomaterials use are also explored — see the full benefits overview for the broader functional-property picture.

Water Solubility

COS is generally more readily water-soluble than conventional chitosan, which is one of the main commercial advantages of the oligosaccharide form for formulators. For the detailed solubility chemistry and formulation behavior, see water-soluble Mushroom Chitosan.

Choosing Between Sources and Forms

Some buyers are still deciding between COS and native mushroom chitosan, or between mushroom-origin and shellfish-origin COS. Source and form both affect molecular weight, solubility, and typical use case — not just labeling. See Mushroom COS vs Native Mushroom Chitosan or Mushroom COS vs Shellfish COS for the full comparisons — supplier choice should ultimately follow your specification, regulatory, and cost requirements, not source alone.

Production and Traceability

Knowing how your COS is produced — and from what starting material — matters for documentation and regulatory purposes, particularly for food and supplement applications. For the full production pathway, see How Mushroom COS Is Produced.

Frequently Asked Questions

Where can I buy Mushroom Chitosan Oligosaccharide?
Through the Mushroom Chitosan Oligosaccharide product page — sample, standard, and bulk quantities are available, with COA provided.

What is a Mushroom COS supplier?
A supplier of chitosan oligosaccharide extracted from fungal (mushroom) chitosan rather than shellfish or insect sources — relevant for buyers seeking non-shellfish positioning.

Is a laboratory sample available?
Yes — a 25 g sample is available with free shipping, intended for evaluation before bulk commitment.

Is a COA available before bulk purchasing?
Yes, the current COA is available — request it before finalizing a bulk order.

What grades are available?
Food, Nutraceutical, and Industrial grades are currently offered. Confirm which grade matches your regulatory pathway before ordering.

Is Mushroom COS water soluble?
Yes — water solubility is one of the defining characteristics of the oligosaccharide form.

What specifications should I check?
Molecular weight, DDA, purity, solubility, and grade at minimum — verify all against the current COA rather than relying on general category descriptions.

How do I request bulk pricing?
Contact us with your required quantity, grade, application, and destination, and we’ll provide current pricing and lead time.

How is Mushroom COS different from shellfish COS?
Both are chemically chitosan oligosaccharide; they differ in biological source and associated labeling considerations (shellfish-free vs. shellfish-derived), not necessarily in molecular specification. See our Mushroom COS vs Shellfish COS comparison for detail.
