Kev siv Chitosan
Jun 25, 2023
Chitosan yog ib hom biopolymer tau los ntawm deacetylation ntawm chitin. Nws cov khoom tshwj xeeb physicochemical, xws li biodegradability, biocompatibility, non-toxicity, thiab adsorption muaj peev xwm, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev lag luam khoom noj. Nyob rau hauv xyoo tas los no, nws tau dav siv los ua ib qho khoom noj khoom haus zoo tshaj plaws vim nws txoj haujlwm ntau yam.
Ua ntej chitosan tuaj yeem siv los ua cov tshuaj tua kab mob hauv kev khaws zaub mov. Ntau cov kev tshawb fawb tau pom tias chitosan thiab nws cov derivatives muaj peev xwm inhibit qhov kev loj hlob ntawm ntau yam kab mob, fungi, thiab kab mob. Cov cuab yeej no tuaj yeem tiv thaiv cov zaub mov tsis zoo thiab txuas ntxiv lub neej txee ntawm cov khoom noj. Nws kuj tseem tuaj yeem siv los ua cov khoom siv txheej los khaws cov khoom zoo, txhim kho cov tsos, thiab tiv thaiv kev kis kab mob thaum lub sijhawm ua zaub mov thiab khaws cia. Secondly, chitosan tuaj yeem siv los ua cov thickener, stabilizer, thiab emulsifier hauv kev tsim khoom noj. Nws qhov hnyav molecular hnyav thiab viscosity ua rau nws yog tus neeg ua haujlwm thickening zoo, uas tuaj yeem txhim kho qhov kev ntxhib los mos thiab lub qhov ncauj ntawm cov khoom noj. Kuj stabilize emulsions thiab tiv thaiv theem sib cais hauv cov khoom noj. Tsis tas li ntawd, siv los ua tus neeg sawv cev hauv cov khoom noj nqaij los yog ntses, uas tuaj yeem txhim kho cov dej tuav thiab nce yield.Thirdly, nws tuaj yeem siv los ua cov khoom noj fiber ntau lossis cov khoom noj muaj txiaj ntsig. Raws li kev noj haus fiber ntau, nws tuaj yeem nqus dej thiab rog, thiab ua kom lub plab hnyav thiab lub sijhawm thauj mus los. Cov cuab yeej no tuaj yeem pab tiv thaiv kab mob plab hnyuv thiab txhawb kev zom zaub mov. Ntxiv mus, nws tuaj yeem tsim cov gels lossis cov yeeb yaj kiab uas tuaj yeem ntim cov as-ham lossis tshuaj, uas tuaj yeem txhim kho lawv cov bioavailability thiab stability.
Hauv kev xaus, chitosan yog cov khoom noj muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo uas tuaj yeem txhim kho qhov zoo thiab kev nyab xeeb ntawm cov khoom noj. Nws muaj ntau txoj haujlwm tuaj yeem ua tau raws li qhov xav tau ntawm kev lag luam khoom noj, xws li kev khaws cia, kev ua, thiab khoom noj khoom haus.
