I-CMC, noma i-Carboxymethyl cellulose, iyisithako sokudla esivame ukusetshenziswa esisebenza njenge-thickener, emulsifier, kanye ne-stabilizer. I-polymer encibilikayo emanzini, i-anionic etholakala ku-cellulose, okuyi-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. I-CMC ikhiqizwa ukuguqulwa kwamakhemikhali e-cellulose kusetshenziswa inqubo ye-carboxymethylation, lapho amaqembu e-carboxymethyl (-CH2COOH) ethulwa ku-molecule ye-cellulose.

I-CMC isetshenziswa kakhulu embonini yokudla njenge-ejenti ejiyayo ngoba inezinto ezinhle kakhulu zokubopha amanzi futhi ingakha ukwakheka okuzinzile okufana nejeli lapho yengezwe emanzini. Ibuye isetshenziswe njenge-stabilizer ukuvimbela ama-emulsions kanye nokumiswa ekuhlukaniseni, futhi njengesibopho sokuthuthukisa ukuthungwa kanye nekhwalithi yokudla okucutshungulwayo.

Izakhiwo ezijiyayo ze-CMC kungenxa yekhono layo lokwenza isakhiwo esifana nejeli lapho ihlangana namanzi. Uma i-CMC yengezwa emanzini, ifaka amanzi futhi ivuvuke, yenze isixazululo se-viscous. I-viscosity yesixazululo incike ekugxilweni kwe-CMC kanye nezinga lokushintshwa, okuyisilinganiso senani lamaqembu e-carboxymethyl anamathiselwe ku-molecule ye-cellulose. Ukuphakama kwe-CMC kanye nezinga eliphezulu lokushintsha, isisombululo sizoba sikhulu.

Izakhiwo ezijiyayo ze-CMC ziyenza ibe isithako esifanele ukusetshenziswa ezinhlobonhlobo zemikhiqizo yokudla, okuhlanganisa amasoso, okokugqoka, amasobho, nezinto ezibhakwayo. Kusoso nezingubo zokugqoka, i-CMC isiza ukuthuthukisa ukuthungwa nokuzinza komkhiqizo, iwuvimbele ukuthi ungahlukaniseki noma ube ngamanzi. Kusobho nezitshulu, i-CMC isiza ukujiyisa umhluzi, uwunikeze ukuthungwa okucebile, okunenhliziyo. Ezimpahleni ezibhakwayo, i-CMC ingasetshenziswa njengesimo senhlama ukuthuthukisa ukuthungwa nempilo yeshalofu yomkhiqizo.

Enye yezinzuzo zokusebenzisa i-CMC njenge-thickener ukuthi iyisithako semvelo esitholakala ezinsizeni ezivuselelekayo. Ngokungafani nama-thickeners okwenziwa, njenge-xanthan gum noma i-guar gum, i-CMC ayikhiqizwa kusetshenziswa amakhemikhali e-petrochemical futhi iyabola. Lokhu kwenza kube inketho evumelana nemvelo kubakhiqizi bokudla.

I-CMC futhi iyisithako esiguquguqukayo esingasetshenziswa ngokuhlanganiswa nezinye izingqimba neziqinisi ukuze kuzuzwe izici ezithile zokusebenza. Isibonelo, i-CMC ingasetshenziswa ngokuhambisana ne-xanthan gum ukuthuthukisa ukuthungwa nokuzinza kwezingubo zesaladi ezinamafutha aphansi. Kulokhu, i-CMC isiza ukujiya ukugqoka futhi ivimbele ukuthi ingahlukani, kuyilapho i-xanthan gum ingeza ukuthungwa okubushelelezi, okukhilimu.

Ngaphezu kwezakhiwo zayo ezijiyayo, i-CMC iphinde isetshenziswe njenge-emulsifier kanye ne-stabilizer ezinhlobonhlobo zemikhiqizo yokudla. Uma yengezwe kumafutha namanzi, i-CMC ingasiza ekuqiniseni i-emulsion, ivimbele amafutha namanzi ukuba ahlukane. Lokhu kuyenza ibe isithako esilungele ukusetshenziswa ekugqokeni kwesaladi, imayonnaise, namanye ama-emulsions kawoyela emanzini.

I-CMC iphinde isetshenziswe njengesizinzisi emikhiqizweni eminingi, okuhlanganisa u-ayisikhilimu, imikhiqizo yobisi, neziphuzo. Ku-ayisikhilimu, i-CMC isiza ukuvimbela ukwakheka kwekristalu yeqhwa, okungase kubangele ukuthungwa okuneqhwa, okuneqhwa. Emikhiqizweni yobisi, i-CMC isiza ukuthuthukisa ukuthungwa nokuzinza komkhiqizo, iwuvimbele ukuthi ungahlukaniseki noma ube ngamanzi. Eziphuzweni, i-CMC ingasetshenziselwa ukuthuthukisa ukuzwakala komlomo nokuthungwa komkhiqizo, iwunikeze ukuguquguquka okubushelelezi, okunokhilimu.

Enye yezinzuzo ezibalulekile zokusebenzisa i-CMC njenge-emulsifier kanye ne-stabilizer ukuthi ingasiza ekunciphiseni inani lezinye izithako, ezifana namafutha noshukela, okudingekayo ukuze kuzuzwe ukuthungwa okufunayo nokuzinza komkhiqizo. Lokhu kungaba yinzuzo kubakhiqizi abafuna ukudala imikhiqizo enempilo noma enekhalori ephansi ngaphandle kokuyekethisa ukunambitheka nokuthungwa.
