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.

Häufig gestellte Fragen
Häufig gestellte Fragen von Herstellern von Nahrungsergänzungsmitteln, OEM-Herstellern, Auftragsfertigern und Einkäufern von Inhaltsstoffen.
Was ist Chitosan?
Chitosan ist ein deacetyliertes Chitin-Polysaccharid, das hauptsächlich aus D-Glucosamin- und N-Acetyl-D-Glucosamin-Einheiten besteht. Bei der Beschaffung von Rohstoffen für Nahrungsergänzungsmittel wird es anhand der Herkunft, des DDA-Werts, der Viskosität, des Molekulargewichtsbereichs, der Partikelgröße, des Feuchtigkeitsgehalts, der Schwermetallbelastung, der mikrobiologischen Eigenschaften und des Chargenzertifikats (COA) bewertet.
Wie lautet die CAS-Nummer von Chitosan?
Die für Chitosan üblicherweise verwendete CAS-Nummer lautet 9012-76-4. Käufer sollten die Identität, die Herkunft, den DDA-Wert, die Viskosität und die Spezifikation anhand der Lieferantenunterlagen und des Chargenzertifikats (COA) überprüfen.
Ist Chitosan ein einzelnes Molekül?
Nein. Chitosan ist ein Polymer, daher wird das Molekulargewicht in der Regel nicht als fester Wert angegeben, sondern als Bereich oder anhand der Viskosität und des Polymerisationsgrades beschrieben.
Was versteht man unter dem Deacetylierungsgrad von Chitosan?
Der Deacetylierungsgrad (DDA) beschreibt den prozentualen Anteil deacetylierter Glucosamin-Einheiten in Chitosan. Er ist ein wichtiger Qualitätsparameter, da er die Ladungsdichte, das Lösungsverhalten und die Anwendungsleistung beeinflusst.
Ist Chitosan wasserlöslich?
Standard-Chitosan ist in neutralem Wasser im Allgemeinen nicht löslich, löst sich jedoch in verdünnten sauren Lösungen. Chitosan-HCl ist eine eigenständige wasserlösliche Form und sollte als separate Spezifikation betrachtet werden.
Was ist der Unterschied zwischen Chitosan und Chitin?
Chitin ist ein natürliches Polysaccharid, das in den Schalen von Krebstieren und anderen biologischen Quellen vorkommt. Chitosan wird durch Deacetylierung von Chitin hergestellt, wodurch die Anzahl der freien Aminogruppen erhöht und sich die Löslichkeit sowie das Ladungsverhalten verändern.
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.
Wird Chitosan aus Schalentieren gewonnen?
Handelsübliches Chitosan wird in der Regel aus Chitin gewonnen, das aus Garnelen- oder Krabbenschalen stammt. Käufer sollten vor der Verwendung des Produkts Angaben zur Herkunft, zur Art, zu Allergenen sowie zu Kreuzkontaminationen einholen.
Ist Chitosan vegan?
Herkömmliches Chitosan wird in der Regel aus Krustentierpanzern gewonnen und ist nicht vegan. Chitosan aus Pilzen oder anderen Quellen als Krustentieren sollte gesondert angefordert und durch Unterlagen des Lieferanten belegt werden.
Kann Chitosan in Kapseln oder Tabletten verwendet werden?
Ja. Chitosan kann für Kapseln und Tabletten in Betracht gezogen werden, sofern Portionsgröße, empfohlene Tagesdosis (DDA), Viskosität, Schüttdichte, Fließfähigkeit, Partikelgröße, Pressverhalten und Stabilität den Anforderungen entsprechen.
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.
Welche Qualitätsindikatoren sollten überprüft werden?
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.
Welche Unterlagen kann ich vor der Bestellung anfordern?
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.
