Oligochitosan (low molecular weight chitosan) sits between chitosan and chitosan oligosaccharide — retaining chitosan’s film-forming and bioactivity while gaining improved solubility and absorption. A versatile functional ingredient for food, feed, agriculture and biomaterial applications.
Product Specification
- Source: crab/shrimp shell chitosan
- Appearance: light yellow to off-white powder
- Solubility: soluble in dilute acids; partial water solubility by grade
- Molecular weight: 3000–10000 Da (typical)
- Degree of deacetylation: ≥85%
- Grades: food / feed / agriculture / industrial
Key Benefits
- Bioactive window: balances solubility, activity and cost
- Film-forming: retains chitosan coating/barrier functions
- Antimicrobial: natural antibacterial & antifungal activity
- Absorption: improved over standard chitosan
- Full grade range: one source for all four application grades
Main Applications
- Food coatings: fresh-produce preservation films
- Dietary supplements: fat-binding & cholesterol-support
- Agriculture: seed coating, plant defense induction
- Feed additives: gut health in livestock & aquaculture
- Biomaterials: hydrogels, films & wound dressings

FAQ About Wholesale Oligochitosan
What is Oligochitosan?
Low molecular weight chitosan (3000–10000 Da) with enhanced solubility and bioactivity.
How is it different from COS?
COS is ≤3000 Da and fully water-soluble; oligochitosan retains more film-forming character.
What grades are available?
Food, feed, agriculture and industrial.
Is it antimicrobial?
Yes — natural antibacterial and antifungal activity.
What is the deacetylation degree?
≥85%.
Can it be used for food coating?
Yes — fresh-produce preservation films are a key application.
Do you provide COA and SDS?
Yes — full documentation available on request.
What is the shelf life?
Typically 24 months stored sealed in a cool, dry place.
Can I get samples?
Yes — trial samples available.
What are your MOQ terms?
Flexible MOQ, discussed on inquiry.
