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 siv hauv kev lag luam khoom noj. Nyob rau hauv xyoo tas los no, nws tau dav siv los ua ib qho khoom noj khoom haus ntxiv vim nws muaj ntau yam haujlwm.
Ua ntej, chitosan tuaj yeem siv los ua cov tshuaj tua kab mob rau 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 txheej kom muaj txiaj ntsig zoo, txhim kho cov tsos, thiab tiv thaiv kev sib kis thaum ua zaub mov thiab khaws cia. Thib ob, 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 muaj cov thickener zoo uas tuaj yeem txhim kho kev ntxhib los mos thiab tsw ntawm cov khoom noj. Lawv kuj stabilize emulsions thiab tiv thaiv theem sib cais hauv cov khoom noj. Kuj tseem siv tau los ua cov khoom siv hauv cov nqaij los yog ntses, uas tuaj yeem txhim kho cov dej tuav thiab nce cov qoob loo. Thib peb, 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 tsis tu ncua. Tsis tas li ntawd, nws tuaj yeem tsim cov gels lossis cov yeeb yaj kiab uas tuaj yeem ntim cov khoom noj lossis tshuaj, uas tuaj yeem txhim kho lawv cov bioavailability thiab stability.
Yog li, chitosan yog ib qho khoom noj khoom haus thoob ntiaj teb thiab cog lus tias yuav txhim kho cov khoom noj khoom haus zoo thiab kev nyab xeeb. Nws cov haujlwm ntau tuaj yeem ua tau raws li qhov xav tau ntawm kev lag luam khoom noj khoom haus, xws li kev khaws cia, kev ua thiab khoom noj khoom haus.
