Isifinyezo:Ngokuvamile, i-chitin ibhekisela kakhulu ku-chitosan, eyaziwa nangokuthi i-chitosan, i-chitin e-deacetylated, i-chitin e-deacetylated, i-chitin e-soluble, kanye ne-chitin e-soluble. Ama-solids a-Amorphous, ukujikeleza okuthile [α] D11—3°～+10°。 Cishe ayincibiliki emanzini, kodwa incibilika kuma-acid e-organic njenge-formic acid, i-acetic acid, i-benzoic acid, i-naphthenic acid, kanye nama-acid angaphili kahle. Imikhiqizo yezimboni imhlophe noma i-grey white translucent sheet efana nama-solids anokukhanya okuncane kweparele. Ayinaphunga, i-Chemicalbook ayinabo ubuthi, ibola kalula, futhi iyi-polyelectrolyte yemvelo engavamile ye-cationic. Ama-polysaccharides atholakala nge-hydrolysis ene-alkali noma i-enzymatic hydrolysis enamandla ukuze kususwe amaqembu e-acetyl eqenjini likashukela le-chitin. Incibilika ezixazululweni zamanzi eziphansi ze-acidity, inokuvumelana okuhle kwe-bio, ayinayo i-antigenicity, futhi ayincibiliki eziphuzweni zabantu. Itholakala ku-chitin emagobolondweni ezilwane eziphansi nezitshalo ezitholakala kabanzi emvelweni, njenge-arthropods (shrimp, crab), ngokusabela kwe-deacetylation ngokufaka i-alkali kanye nokushisa.
Isenzo：Kunezindlela ezimbili eziyinhloko zomphumela wokulwa namagciwane we-chitosan: enye ukuthi i-chitosan imunca phezu kwamaseli ukuze yakhe ulwelwesi oluphezulu lwama-molecule, ivimbele ukuthuthwa kwezakhamzimba emaseli, ngaleyo ndlela idlale indima ye-bacteriostatic kanye ne-bactericidal; Enye indlela ukuthi i-chitosan ingena emzimbeni weseli, imunca i-cytoplasm ngama-anion e-Chemicalbook emzimbeni weseli, futhi ibangele ukugoba, iphazamise imisebenzi evamile yomzimba weseli, ngaleyo ndlela ibulale amabhaktheriya. Ngenxa yezakhiwo ezahlukene zodonga lwamaseli zama-bacteria ane-gram positive kanye nama-bacteria ane-gram negative, kanye namazinga ahlukene ethonya lemiphumela emibili kuwo, i-chitosan enesisindo sama-molecule ahlukene inezindlela ezahlukene zokulwa namagciwane. I-Chitosan iyi-fiber yokudla enemiphumela yokunciphisa i-cholesterol egazini, ukulawula izitshalo zamathumbu, kanye nokwehlisa umfutho wegazi. Ngemva kokugwinya i-chitosan kubantu, ukuhlaziywa kwendle kukhombisa ukuthi cishe ayigaywanga futhi ayimuncwa, ngakho-ke iyingxenye ye-fiber yokudla.
Njengamanje, i-ZhongAn isungule ukuxhumana nemakethe yase-USA, futhi iyaqhubeka nokubahlinzeka nge-Chitosan njalo ngenyanga. Uma unesidingo, ungaxhumana ne-ZhongAn, futhi i-ZhongAn izokunikeza izimpahla nezinsizakalo ezinhle kakhulu.
