I-Xanthan Gum Powder Ukudla Ibanga Fufeng Xanthan Gum 200 Mesh CAS 11138-66-2

Incazelo Yomkhiqizo:

I-Xanthan gum, eyaziwa nangokuthi i-xanthanic acid, iyi-polysaccharide ye-polymer esetshenziswa kakhulu ekudleni, emithini yemithi, kwezimonyo nakwezinye izimboni ngenxa yezakhiwo zayo zejeli ezinhle kakhulu nokuzinza.

Nasi isingeniso esifushane kwezinye zezakhiwo zomzimba nezamakhemikhali ze-xanthan gum:

Ukubukeka nokuncibilika: I-Xanthan gum iyimpuphu emhlophe kuya kokumhlophe. Ine-solubility enhle kakhulu emanzini futhi yenza izixazululo ze-viscous.

Izakhiwo ze-Gel: I-Xanthan gum ingakha isakhiwo sejeli esizinzile ngaphansi kokuhlushwa okufanele kanye nezimo ze-pH. I-xanthan gum gel ngemuva kokwakhiwa kwejeli ine-viscosity, elasticity nokuzinza, okungakhuphula i-viscosity yomkhiqizo, ithuthukise ukuthungwa, futhi iqinise ama-emulsions nokumiswa.

Ukuzinza kwe-pH: I-Xanthan gum ibonisa ukuzinza okuhle phakathi kwebanga le-pH elivamile (pH 2-12) futhi ayijwayele ukuwohloka noma ukwehluleka kwejeli.

Ukuqina kwezinga lokushisa: I-Xanthan gum ibonisa ukuzinza okuhle phakathi kwebanga elithile lokushisa. Ngokuvamile, ukusebenza kwe-xanthan gum ngeke kuthinteke kakhulu ebangeni lika-50-100 degrees Celsius.

I-Oxidation: I-Xanthan gum inokusimama okuhle kakhulu kwe-oxidation futhi ayithambekele ekuphenduleni kwe-oxidation kanye nokulimala kwama-radical mahhala.

Ukusebenzisana phakathi kwe-ion yensimbi esindayo ne-xanthan gum: I-Xanthan gum ingabhekana nokusabela okuyinkimbinkimbi ngama-ion ahlukahlukene. Ngokukhethekile, ama-ion ensimbi afana ne-ammonium ion, i-calcium ions, nama-lithium ion angasebenzisana ne-xanthan gum futhi athinte ukusebenza nokuzinza kwayo.

Ukubekezelelwa kukasawoti: I-Xanthan gum ingamelana nokugcwala okuphezulu kwezisombululo zikasawoti futhi ayijwayele ukwehluleka kwejeli noma imvula.

Sekukonke, i-xanthan gum inokusimama okuhle, i-gelling kanye ne-solubility futhi ingadlala indima ebalulekile emikhakheni ehlukene. Izakhiwo zayo ezingokomzimba namakhemikhali zenza i-xanthan gum ibe isithako esibalulekile emikhiqizweni eminingi efana nejusi, ukudla kwejeli, okokugcoba, amaphilisi emithi, amaconsi iso, izimonyo, njll.

Isebenza kanjani i-Xanthan Gum?

I-Xanthan gum isetshenziswa njenge-thickener ne-stabilizer ekudleni okuhlukahlukene, izidakamizwa, nezimonyo. Kubangelwa ukuvutshelwa kwama-carbohydrate wuhlobo oluthile lwamagciwane olubizwa ngokuthi i-Xanthomonas campestris. Indlela yokusebenza ye-Xanthan gum ihilela ukwakheka kwayo okuyingqayizivele kwamangqamuzana. Iqukethe amaketanga amade ama-molecule kashukela (ikakhulukazi i-glucose) exhunywe kwelinye ngamaketanga aseceleni abanye ushukela. Lesi sakhiwo sisenza sikwazi ukusebenzisana namanzi futhi senze isisombululo se-viscous noma ijeli.

Lapho i-xanthan gum ihlakazwa oketshezini, inika amanzi futhi yakhe inethiwekhi yamaketanga amade, aphithene. Le nethiwekhi isebenza njenge-thickener, ikhulisa i-viscosity ye-liquid. Ubukhulu noma i-viscosity incike ekugxilweni kwe-xanthan gum esetshenzisiwe. Ukuqina komphumela we-xanthan gum kungenxa yekhono layo lokugcina amanzi futhi livimbele ukuthi lihlukane. Yakha isakhiwo sejeli esizinzile esivalela ama-molecule amanzi, senze ukuthungwa okuminyene, okukhilimu oketshezini. Lesi sakhiwo siwusizo ikakhulukazi ekusetshenzisweni okudinga ukuthungwa okuhle nokuzwakala komlomo, njengamasoso, okokugqoka kanye nemikhiqizo yobisi.

Ngaphezu komphumela wayo wokuqina, i-xanthan gum nayo inomphumela wokuzinzisa. Isiza ukugcina ukufana komkhiqizo kanye nokufana ngokuvimbela izithako ukuthi zingahlali noma zihlukanise. Iqinisa ama-emulsions, ukumiswa kanye namagwebu, iqinisekisa ukuzinza komkhiqizo wesikhathi eside. Ukwengeza, i-xanthan gum ibonisa ukuziphatha kwe-pseudoplastic, okusho ukuthi iyancipha uma ingaphansi kwamandla okugunda njengokunyakazisa noma ukupompa. Lesi sici sivumela umkhiqizo ukuthi ukhiphe noma ugeleze kalula ngenkathi ugcina ukuvumelana okufunayo lapho uphumule. Sekukonke, indima ye-xanthan gum ukwakha i-matrix enezinhlangothi ezintathu esixazululweni esijiya, esisimamisa futhi sinikeze izakhiwo ezifiselekayo zombhalo emikhiqizweni eyahlukene.

Isitatimende se-Kosher:

Siyaqinisekisa ngalokhu ukuthi lo mkhiqizo uqinisekisiwe kumazinga e-Kosher.
