Chitosan Oligosaccharide (COS) is the depolymerized, water-soluble form of chitosan, produced by enzymatic degradation with our own invention patent. It dissolves completely in water at neutral pH — unlocking the bioactivity of chitosan for food, feed, agriculture and industrial applications.
Product Specification
- Source: crab/shrimp shell chitosan (enzymatic hydrolysis)
- Appearance: light yellow to white powder
- Solubility: freely soluble in water (neutral pH)
- Degree of deacetylation: ≥90%
- Molecular weight: ≤3000 Da (average)
- Grades: food / feed / agriculture / industrial
- Patent: own invention patent production process
Key Benefits
- Water-soluble: dissolves at neutral pH — no acid needed
- High bioactivity: low MW = high absorption & activity
