Umkhiqizi Intengo Enhle I-Xanthan Gum Ibanga Lezimboni I-CAS：11138-66-2

incazelo emfushane:

I-Xanthan gum, eyaziwa nangokuthi i-Hanseonggum, uhlobo lwe-microbial exopolysaccharide ekhiqizwa yi-Xanthomnas campestris ene-carbohydrate njengezinto eziyinhloko zokusetshenziswa (njengesitashi sommbila) ngokusebenzisa ubunjiniyela bokuvubela. Ine-rheology ehlukile, ukuncibilika kwamanzi okuhle, ukuzinza kokushisa kanye nesisekelo se-asidi, futhi ihambisana kahle nezinhlobonhlobo zosawoti. Njenge-ejenti yokujiya, i-suspension agent, i-emulsifier, i-stabilizer, ingasetshenziswa kabanzi ekudleni, kuphethiloli, kwezokwelapha nakwezinye izimboni ezingaphezu kuka-20, okwamanje iyisilinganiso sokukhiqiza esikhulu kunazo zonke emhlabeni futhi i-microbial polysaccharide esetshenziswa kakhulu.

I-Xanthan gum iyimpuphu enyakazayo ephuzi kancane kuya komhlophe, inephunga elincane. Incibilika emanzini abandayo nashisayo, iyisisombululo esingathathi hlangothi, imelana nokubanda nokuncibilika, ayincibiliki ku-ethanol. Ukusabalala kwamanzi, i-emulsification ibe yi-colloid eqinile ye-hydrophilic viscous.

Izici

1） Ngokwanda kwesilinganiso sokucheba, izakhiwo ezijwayelekile ze-rheological, ngenxa yokubhujiswa kwenethiwekhi ye-colloidal, zinciphisa i-viscosity futhi zinciphise i-glue, kodwa uma amandla okucheba esenyamalala, i-viscosity ingabuyiselwa, ngakho-ke inezakhiwo ezinhle zokupompa nokucubungula. Ngokusebenzisa lesi sici, i-xanthan gum yengezwa kuketshezi oludinga ukujiya. Uketshezi alugcini nje ngokugeleza kalula enkambisweni yokuthutha, kodwa futhi lungabuyela ku-viscosity edingekayo ngemuva kokuba lusamile. Ngakho-ke, lusetshenziswa kabanzi embonini yeziphuzo.

2）Uketshezi olune-viscosity ephezulu oluqukethe i-2% ~ 3% xanthan gum ekugxilweni okuphansi, olune-viscosity efinyelela ku-3 ~ 7Pa.s. I-viscosity yayo ephezulu yenza kube namathuba amaningi okusetshenziswa, kodwa ngesikhathi esifanayo, iletha inkinga ngemuva kokucutshungulwa komkhiqizo. I-0.1% NaCl kanye nezinye usawoti olinganayo kanye ne-Ca, Mg kanye nezinye usawoti ohlangene kunganciphisa kancane i-viscosity yesisombululo se-glue esiphansi ngaphansi kuka-0.3%, kodwa kungandisa i-viscosity yesisombululo se-glue ngokugxilwa okuphezulu.

3） I-viscosity ye-xanthan gum engashisi ayinalo nhlobo ushintsho ebangeni lokushisa elibanzi (- 98~90 ℃). I-viscosity yesisombululo ayizange ishintshe kakhulu noma ngabe igcinwe ku-130 ℃ imizuzu engama-30 bese ipholiswa. Ngemva kwemijikelezo eminingana yokuqandisa, i-viscosity yeglue ayizange ishintshe. Uma kukhona usawoti, isixazululo sinokuzinza okuhle kokushisa. Uma inani elincane le-electrolyte, njenge-0.5% NaCl, lingezwa ekushiseni okuphezulu, i-viscosity yesisombululo seglue ingaqiniswa.

4） I-viscosity yesisombululo samanzi se-xanthan gum esimelana ne-asidi kanye ne-alkaline gum cishe ayincikile ku-pH. Lesi sici esiyingqayizivele asinazo ezinye izinto eziqinisayo njenge-carboxymethyl cellulose (CMC). Uma ukuhlushwa kwe-inorganic acid esixazululweni seglue kuphezulu kakhulu, isixazululo seglue sizoba sizinzile; Ngaphansi kokushisa okuphezulu, kuzokwenzeka i-hydrolysis ye-polysaccharide yi-asidi, okuzobangela ukuthi i-viscosity yeglue yehle. Uma okuqukethwe yi-NaOH kungaphezu kuka-12%, i-xanthan gum izofakwa i-gel noma ivele ivele. Uma ukuhlushwa kwe-sodium carbonate kungaphezu kuka-5%, i-xanthan gum nayo izofakwa i-gel.

5） I-anti-enzymatic xanthan gum skeleton inekhono eliyingqayizivele lokungafakwa i-hydrolyzed ngama-enzyme ngenxa yomphumela wokuvikela wamaketanga aseceleni.

6） I-xanthan gum ehambisanayo ingaxutshwa nezixazululo ezivame ukusetshenziswa kakhulu zokujiya kokudla, ikakhulukazi nge-alginate, isitashi, i-carrageenan kanye ne-carrageenan. Ukuqina kwesisombululo kuyanda ngesimo se-superposition. Kubonisa ukuhambisana okuhle ezixazululweni zamanzi ezinosawoti ahlukahlukene. Kodwa-ke, ama-ion ensimbi aphezulu e-valence kanye ne-pH ephezulu kuzokwenza zingazinzile. Ukwengeza i-ejenti eyinkimbinkimbi kungavimbela ukwenzeka kokungahambelani.

7） I-xanthan gum encibilikayo incibilika kalula emanzini futhi ayincibiliki ezinyibilikisini ze-polar ezifana notshwala ne-ketone. Ezingeni lokushisa elibanzi kakhulu, i-pH kanye nokuhlushwa kukasawoti, kulula ukuyincibilika emanzini, futhi isixazululo sayo samanzi singalungiswa ekushiseni kwegumbi. Uma uvuselela, ukuxubana komoya kufanele kuncishiswe. Uma i-xanthan gum ixutshwa nezinto ezomile kusengaphambili, njengosawoti, ushukela, i-MSG, njll., bese imanziswa ngamanzi amancane, futhi ekugcineni ixutshwe namanzi, isixazululo seglue esilungisiwe sisebenza kangcono. Singancibilika ezixazululweni eziningi ze-organic acid, futhi ukusebenza kwaso kuzinzile.

8） Umthamo wokuthwala wesisombululo se-xanthan gum esingu-1% esisakazekayo ngu-5N/m2, okuyi-ejenti yokumisa enhle kakhulu kanye ne-emulsion stabilizer ezithasiselweni zokudla.

9） I-xanthan gum egcina amanzi inokugcina amanzi okuhle kanye nemiphumela yokugcina ukudla okusha.

Izicelo zebanga le-Xanthan Gum Industrial

1） Ekubholeni embonini kaphethiloli, isixazululo samanzi se-xanthan gum esingu-0.5% singagcina i-viscosity yoketshezi lokubhoboza olusekelwe emanzini futhi silawule izakhiwo zalo ze-rheological, ukuze i-viscosity yama-bits ajikelezayo ngesivinini esikhulu ibe phansi kakhulu, okusindisa kakhulu ukusetshenziswa kwamandla, kanti ezingxenyeni zokubhoboza ezingaguquki, ingagcina i-viscosity ephezulu, edlala indima ekuvimbeleni ukubhidlika kwe-wellbore kanye nokwenza kube lula ukususwa kwetshe elichotshoziwe ngaphandle komthombo.

2）Embonini yokudla, kungcono kunezithasiselo zokudla zamanje njenge-gelatin, i-CMC, i-seaweed gum kanye ne-pectin. Ukwengeza u-0.2% ~ 1% kujusi kwenza ijusi libe nokunamathela okuhle, ukunambitheka okuhle, futhi kulawule ukungena nokugeleza; Njengesengezo sesinkwa, kungenza isinkwa siqine, sibe bushelelezi, konge isikhathi futhi kunciphise izindleko; Ukusetshenziswa kuka-0.25% ekugcwaliseni isinkwa, ukugcwalisa amasangweji okudla kanye nokugqoka ushukela kungandisa ukunambitheka nokunambitheka, kwenze umkhiqizo ube bushelelezi, kwandise impilo yeshelufu, futhi kuthuthukise ukuzinza komkhiqizo ekushiseni nasekuqandeni; Emikhiqizweni yobisi, ukwengeza u-0.1% ~ 0.25% ku-ayisikhilimu kungadlala indima enhle kakhulu yokuzinza; Kunikeza ukulawula okuhle kwe-viscosity ekudleni okusemathinini futhi kungathatha indawo yengxenye yesitashi. Ingxenye eyodwa ye-xanthan gum ingathatha indawo yezingxenye ezingu-3-5 zesitashi. Ngesikhathi esifanayo, i-xanthan gum nayo isetshenziswe kabanzi kumaswidi, izinongo, ukudla okuqandisiwe kanye nokudla okuwuketshezi.
