What Is Chitosan?
Chitosan is a deacetylated chitin polysaccharide commonly supplied as a shellfish-derived powder for supplement raw material sourcing.
Chitosan is a linear polysaccharide made mainly of D-glucosamine and N-acetyl-D-glucosamine units. In commercial supplement sourcing, it is commonly produced by deacetylating chitin from shrimp or crab shells. Since chitosan is a polymeric material, buyers should evaluate degree of deacetylation, viscosity, molecular weight range, source, ash, moisture, particle size, solubility behavior, heavy metals, microbiology, shellfish allergen statement, source declaration, packaging and destination-market label requirements instead of relying on one fixed molecular weight.
Degree of Deacetylation
DDA is one of the most important purchasing specifications because it influences charge density, solubility behavior and application performance.
Viscosity & MW Review
Chitosan is often selected by viscosity and molecular weight range, not by one fixed molecular weight value.
Source Declaration
Shrimp or crab shell source, shellfish allergen status and cross-contact information should be confirmed before label use.
Chitosan Specification Options
Final specifications depend on chitin source, deacetylation process, DDA, viscosity, molecular weight, mesh size, packaging and destination market requirements.

Câu hỏi thường gặp
Các câu hỏi thường gặp từ các thương hiệu thực phẩm chức năng, nhà sản xuất OEM, nhà sản xuất gia công và các đơn vị mua nguyên liệu.
Chitosan là gì?
Chitosan is a deacetylated chitin polysaccharide made mainly of D-glucosamine and N-acetyl-D-glucosamine units. In supplement raw material sourcing, it is evaluated by source, DDA, viscosity, molecular weight range, particle size, moisture, heavy metals, microbiology and batch COA.
What is the CAS number of Chitosan?
The CAS number commonly used for Chitosan is 9012-76-4. Buyers should confirm identity, source, DDA, viscosity and specification by supplier documents and batch COA.
Is Chitosan a single molecule?
No. Chitosan is a polymeric material, so molecular weight is usually expressed as a range or described by viscosity and degree of polymerization rather than one fixed molecular weight.
What is degree of deacetylation in Chitosan?
Degree of deacetylation, or DDA, describes the percentage of deacetylated glucosamine units in chitosan. It is a key quality parameter because it affects charge density, solubility behavior and application performance.
Is Chitosan water soluble?
Standard Chitosan is generally not soluble in neutral water but is soluble in dilute acidic solutions. Chitosan HCl is a separate water-soluble form and should be reviewed as a different specification.
What is the difference between Chitosan and Chitin?
Chitin is the natural polysaccharide found in crustacean shells and other biological sources. Chitosan is produced by deacetylating chitin, which increases free amino groups and changes solubility and charge behavior.
What is the difference between Chitosan and Chitosan HCl?
Chitosan is the standard deacetylated chitin polymer, while Chitosan HCl is a hydrochloride salt form designed for better water solubility. They should be sourced, specified and labeled separately.
Is Chitosan shellfish derived?
Commercial Chitosan is commonly derived from shrimp or crab shell chitin. Buyers should request source declaration, species information, allergen statement and cross-contact information before label use.
Is Chitosan vegan?
Traditional Chitosan is usually crustacean shell-derived and is not vegan. Fungal or non-crustacean chitosan options should be requested separately and supported by supplier documentation.
Can Chitosan be used in capsules or tablets?
Yes. Chitosan can be evaluated for capsules and tablets when serving size, DDA, viscosity, bulk density, flowability, particle size, compression behavior and stability are suitable.
Can Chitosan be used in drink powders?
Standard Chitosan is not neutral-water soluble, so drink powder concepts should be tested for acid pH compatibility, dispersion, texture, sediment, taste and label positioning. Chitosan HCl may be reviewed when water solubility is required.
What quality indicators should be checked?
Buyers should review source, DDA, viscosity, molecular weight range, pH, loss on drying, ash, acid-insoluble matter, particle size, bulk density, heavy metals, microbiology, allergen status and batch COA.
Tôi có thể yêu cầu những tài liệu nào trước khi đặt hàng?
Qualified B2B buyers can request COA, specification sheet, SDS, TDS, source declaration, allergen statement, non-GMO statement, residual chemical report, flow chart, stability information and other technical files depending on the selected grade.
