Chitosan

Beschreibung:

Chitosan ist ein Biopolymer, das aus Chitin gewonnen wird, das in den Exoskeletten von Krebstieren wie Garnelen und Krabben vorkommt. Es zeichnet sich durch sein weißes bis schmutzig-weißes Pulver aus und ist in sauren Lösungen löslich, was es von seinem Vorläufer, Chitin, unterscheidet, das in Wasser unlöslich ist. Chitosan weist mehrere bemerkenswerte Eigenschaften auf, darunter Biokompatibilität, biologischen Abbaubarkeit und Nicht-Toxizität, die es für verschiedene Anwendungen in der Medizin, Landwirtschaft und Lebensmittelindustrie geeignet machen. Seine Fähigkeit, Gele und Filme zu bilden, ermöglicht die Verwendung in Arzneimittelabgabesystemen, Wundverbänden und als Lebensmittelkonservierungsmittel. Darüber hinaus besitzt Chitosan antimikrobielle Eigenschaften, die das Wachstum bestimmter Bakterien und Pilze hemmen können. Der Grad der Deacetylierung, der sich auf den Anteil der von der Chitinstruktur entfernten Acetylgruppen bezieht, beeinflusst erheblich seine Löslichkeit und funktionalen Eigenschaften. Insgesamt ist Chitosan ein vielseitiges und umweltfreundliches Material mit einem breiten Spektrum an potenziellen Anwendungen.

Chitosan - non-animal origin

CAS: 9012-76-4

Chitosan is the deacetylated form of chitin. The polysaccharide is deacetylated in order to render it soluble, which is then possible at pH values of less than 7 (normally in dilute acid). This then allows the material to be used in a number of industrial applications as a binder and film former.
