Xanthan gum le Hydroxyethyl cellulose (HEC) ka bobeli ke li-hydrocolloids tse sebelisoang haholo liindastering tse fapaneng, haholo lijong, meriana le lihlahisoa tsa tlhokomelo ea motho.Ho sa tsotellehe ho tšoana ho itseng litšebelisong tsa bona, li fapane ho ea ka sebōpeho sa lik'hemik'hale, thepa le mesebetsi.
1. Sebopeho sa Lik'hemik'hale:
Xanthan gum: Ke polysaccharide e nkiloeng ho belisoa ha lik'habohaedreite, haholo-holo tsoekere, ke baktheria Xanthomonas campestris.E na le mokokotlo oa masala a tsoekere a nang le liketane tse ka mahlakoreng tsa likarolo tse pheta-phetoang tsa trisaccharide, ho kenyeletsoa mannose, glucuronic acid le glucose.
HEC: Hydroxyethyl cellulose ke ether e seng ea ionic cellulose e tsoang ho cellulose, polysaccharide ea tlhaho e fumanehang marakong a lisele tsa limela.HEC e fetoloa ka ho hlahisa lihlopha tsa hydroxyethyl mokokotlong oa cellulose.
2.Solubility:
Xanthan gum: E bonts'a ho qhibiliha ho holimo metsing a batang le a chesang.E etsa litharollo tsa viscous haholo esita le maemong a tlase.
HEC: Hydroxyethyl cellulose e qhibiliha ka metsing, 'me ho qhibiliha ha eona ho ka fapana ho itšetlehile ka tekanyo ea ho fetola (DS) ea lihlopha tsa hydroxyethyl.DS e phahameng hangata e fella ka ho qhibiliha ho betere.
3.Viscosity:
Xanthan gum: E tsebahala ka thepa ea eona e ikhethang e teteaneng.Leha e le maemong a tlase, xanthan gum e ka eketsa viscosity ea tharollo haholo.
HEC: The viscosity ea tharollo ea HEC e boetse e itšetlehile ka lintlha tse kang ho tsepamisa mohopolo, mocheso le sekhahla sa ho kuta.Ka kakaretso, HEC e bonts'a thepa e ntle ea ho tenya, empa viscosity ea eona e tlase ha e bapisoa le xanthan gum ka likhakanyo tse lekanang.
4.Ho Shear Thinning Behaviour:
Xanthan gum: Tharollo ea xanthan gum hangata e bonts'a boitšoaro ba ho kuta, ho bolelang hore viscosity ea bona e fokotseha tlas'a khatello ea ho kuta 'me e hlaphoheloa hang ha khatello e tlosoa.
HEC: Ka ho tšoanang, litharollo tsa HEC li boetse li bontša boitšoaro ba ho kuta, le hoja tekanyo e ka fapana ho itšetlehile ka boemo bo itseng le maemo a tharollo.
5.Ho lumellana:
Xanthan gum: E lumellana le mefuta e mengata e mengata ea li-hydrocolloids le metsoako e atisang ho sebelisoa lijong le ho etsoa ha tlhokomelo ea botho.E ka boela ea tsitsisa emulsions.
HEC: Hydroxyethyl cellulose e boetse e lumellana le metsoako e fapaneng 'me e ka sebelisoa hammoho le li-thickeners tse ling le li-stabilizers ho finyella thepa ea rheological e lakatsehang.
6.Synergy le Li-Thickeners tse ling:
Xanthan gum: E bonts'a litlamorao tsa synergistic ha e kopantsoe le li-hydrocolloid tse ling joalo ka guar gum kapa lerenene la tsie, e bakang viscosity le botsitso.
HEC: Ka mokhoa o ts'oanang, HEC e ka sebelisana le li-thickeners le li-polymers tse ling, e fana ka mefuta e mengata ea ho etsa lihlahisoa tse nang le litlhoko tse itseng tsa sebopeho le ts'ebetso.
7. Libaka tsa Kopo:
Xanthan gum: E fumana lisebelisoa tse ngata lihlahisoa tsa lijo (mohlala, li-sauces, liaparo, lihlahisoa tsa lebese), lihlahisoa tsa tlhokomelo ea botho (mohlala, litlolo, litlolo, sesepa sa meno), le lihlahisoa tsa indasteri (mohlala, maro a ho cheka, lipente).
HEC: Hydroxyethyl cellulose e atisa ho sebelisoa lihlahisoa tsa tlhokomelo ea botho (mohlala, li-shampoo, litlhatsuoa tsa 'mele, litlolo), meriana (mohlala, litharollo tsa mahlo, li-oral suspensions), le thepa ea kaho (mohlala, lipente, li-adhesives).
8.Litšenyehelo le ho ba Teng:
Xanthan gum: Ka kakaretso e theko e boima haholo ha e bapisoa le HEC, haholo-holo ka lebaka la ts'ebetso ea ho belisoa e amehang tlhahisong ea eona.Leha ho le joalo, tšebeliso e pharaletseng ea eona le ho fumaneha ha eona ho tlatsetsa phepelong ea eona ea 'maraka e batlang e tsitsitse.
HEC: Hydroxyethyl cellulose e batla e na le litšenyehelo tse ngata ha e bapisoa le xanthan gum.E hlahisoa haholo ka phetoho ea lik'hemik'hale ea cellulose, e leng ngata ka tlhaho.
ha xanthan gum le HEC li arolelana lintho tse ling tse tšoanang le likopo tsa tsona tse kang hydrocolloids, li bontša phapang e fapaneng ho latela lik'hemik'hale tsa tsona tsa lik'hemik'hale, solubility, viscosity, shear-thinning behavior, compibility, synergy le li-thickeners tse ling, libaka tsa kopo, le litšenyehelo.Ho utloisisa liphapang tsena ke habohlokoa hore baetsi ba lihlahisoa ba khethe hydrocolloid e loketseng ka ho fetisisa bakeng sa mefuta e itseng ea lihlahisoa le litšobotsi tse lakatsehang tsa tshebetso.
