O mea tau vailaau
Pa'epa'e amorphous mea manino, e aofia ai le 9% nitrogen, leai se tofo ma leai se manogi.
Fa'aoga
Faʻaaogaina i meaʻai, vailaʻau, fatu faʻatoʻaga, vailaʻau i aso taʻitasi, vailaʻau faʻaleagaina vai ma isi pisinisi.Chito-oligosaccharides e mafai ona faʻaleleia le puipuiga, faʻagaoioia sela, puipuia le kanesa, faʻaitiitia le toto toto, toto toto, anti-matua, faʻatonutonu le siosiomaga o le tino ma isi galuega, lea e mafai ona faʻaaogaina i vailaʻau, tausiga faʻalesoifua maloloina, fanua taumafa.I le tulaga o le puipuiga o le siosiomaga, o le chitosan e mafai ona faʻaaogaina mo togafitiga o otaota, toe faʻaleleia o le protein, faʻamamaina vai ma isi.I totonu o le fanua o mea aoga, shell Chemicalbook e mafai ona faʻaaogaina e fai ma mea membrane, ave, absorbents, fibers, mea faʻafomaʻi, ma isi. I totonu o le textile field, chitosan e mafai ona faʻaaogaina mo le faʻamaeʻaina o ie, ofu i lalo ole soifua maloloina, fesoasoani pepa ma isi.Fa'ato'aga fanua e mafai ona fa'aoga i le fa'aopoopoga o fafaga, togafiti fatu, fa'aleleia o le eleele, fa'asaoina o fualaau 'aina ma isi.I le matata o le tapaa, o le chitosan o se mea faʻapipiʻi lelei tapaa, ma ei ai uiga o le faʻaleleia o le tofo, faʻafefeteina e le oona ma leai se manogi uiga ese.
Auala gaosiga
Fa'aopopo le 20g chitin i le 300mL 50% NaOH solution, fa'asusu atoa, vevela ma taofi i le 95 ℃ mo le 1.5h, fa'amama ese le lye, fufulu i le vai e le fa'aituau, fa'agogo i le maualalo o le vevela e maua ai se mea e leai ni lanu manino 15.6g.
Tulaga taumafa
(1) Su'i fa'ama'i
(2) Fa'asao fualaau 'aina ma fualaau faisua
(3) Fa'aopoopo mo mea'ai mo le soifua maloloina
(4) Fa'amalamalamaga mo sua suamalie
Vasega Fa'ato'aga
(1) I faʻatoʻaga, o le chitosan e masani ona faʻaaogaina e avea o se togafitiga faʻanatura fatu ma faʻaleleia le tuputupu aʻe o laʻau, ma o se vailaʻau biopesticides faʻalelei e faʻaleleia ai le malosi faʻanatura o laau e puipuia ai i latou lava mai faʻamaʻi pipisi.
(2) E pei o meaʻai faaopoopo, e mafai ona faʻalavelave ma faʻaumatia le siama leaga, faʻaleleia le puipuiga o manu.
Vasega Alamanuia
(1) Chitosan ei ai uiga lelei adsorption o uʻamea mamafa ion, faʻaaogaina i togafitiga o otaota otaota, vai otaota vai, vai faʻamamaina ma fale gaosi oloa.
(2) Chitosan e mafai foi ona faʻaaogaina i le gaosiga o pepa, faʻaleleia le malosi matutu ma susu o pepa ma luga o le lolomiina.
Carboxymethyl Chitosan
Carboxymethyl Chitosan o le maualuga maualuga o le chitosan, lea e 100% vai solubility, ata tifaga gafatia, chelation uamea mamafa.Ua faʻaaogaina i mea teuteu faʻalelei, uʻamea mamafa chelating agent, vailaʻau faʻasaʻo faʻamalolo, sui faʻatonutonu tuputupu aʻe laau, togafitiga vai otaota, ma isi.
