Ibanga lokudla le-sodium carboxymethyl cellulose (CMC)

Ibanga lokudla i-sodium carboxymethyl cellulose (CMC) iyisengezo sokudla esiguquguqukayo nesiguquguqukayo esaziwa ngezakhiwo zaso ezihlukile kanye nezinhlelo zokusebenza ezahlukahlukene embonini yokudla. I-CMC isuselwa ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo, futhi ibhekana nochungechunge lokuguqulwa kwamakhemikhali ukuze kuthuthukiswe ukunyibilika nokusebenza kwayo.

Izici zebanga lokudla i-sodium carboxymethyl cellulose:

I-Solubility: Enye yezinto eziphawulekayo ze-CMC yebanga lokudla ukuncibilika kwayo okuphezulu emanzini abandayo nashisayo. Lesi sakhiwo senza kube lula ukuhlanganisa ezinhlobonhlobo zokudla neziphuzo.

I-Viscosity: I-CMC ihlonishwa ngekhono layo lokushintsha i-viscosity yesisombululo. Isebenza njenge-ejenti yokuqina, ihlinzeka ukuthungwa nokuvumelana ekudleni okuhlukahlukene, njengamasoso, okokugqoka, nemikhiqizo yobisi.

Ukuzinza: I-CMC yezinga lokudla ithuthukisa ukuzinza kwe-emulsion, ivimbele ukuhlukaniswa kwesigaba futhi yandise impilo yeshalofu yomkhiqizo. Lokhu kwenza kube isithako esibalulekile ekudleni okuningi okugayiwe.

Izakhiwo zokwakha ifilimu: I-CMC ingakha amafilimu amancane, awusizo ezinhlelweni ezidinga izendlalelo ezivikelayo ezincanyana. Lesi sakhiwo sisetshenziswa kumaswidi nanjengesendlalelo sokuvimbela kwezinye izinto zokupakisha.

I-Pseudoplastic: Ukuziphatha kwe-rheological kwe-CMC ngokuvamile kuyi-pseudoplastic, okusho ukuthi i-viscosity yayo iyancipha ngaphansi kwengcindezi ye-shear. Lesi sakhiwo sinenzuzo ezinqubweni ezifana nokupompa kanye nokukhipha.

Ukuhambisana nezinye izithako: I-CMC iyahambisana nezinhlobonhlobo zezithako ezivame ukusetshenziswa embonini yokudla. Lokhu kuhambisana kunomthelela ekusebenzisaneni kwayo ngezindlela eziningi kanye nokusetshenziswa kabanzi.

Inqubo Yokukhiqiza:

Ukukhiqizwa kwe-CMC yebanga lokudla kuhilela izinyathelo eziningi zokushintsha i-cellulose, ingxenye eyinhloko yezindonga zamaseli ezitshalo. Inqubo ngokuvamile ihlanganisa:

Ukwelashwa kwe-alkali: Ukwelapha i-cellulose nge-alkali (imvamisa i-sodium hydroxide) ukwenza i-alkali cellulose.

I-Etherification: I-alkaline cellulose ihlangana ne-monochloroacetic acid ukwethula amaqembu e-carboxymethyl kuketango eliyinhloko le-cellulose. Lesi sinyathelo sibalulekile ukuze kwandiswe ukuncibilika kwamanzi komkhiqizo wokugcina.

I-Neutralization: Yenza kube maphakathi umkhiqizo wokusabela ukuze uthole usawoti we-sodium we-carboxymethylcellulose.

Ukuhlanzwa: Umkhiqizo ongahluziwe uthola isinyathelo sokuhlanza ukususa ukungcola ukuze kuqinisekiswe ukuthi umkhiqizo wokugcina we-CMC uhlangabezana namazinga ebanga lokudla.

Izicelo embonini yokudla:

I-CMC yebanga lokudla inezinhlobonhlobo zezicelo embonini yokudla, isiza ukuthuthukisa ikhwalithi nokusebenza kwemikhiqizo ehlukahlukene. Ezinye izinhlelo zokusebenza eziphawulekayo zihlanganisa:

Imikhiqizo Ebhakiwe: I-CMC isetshenziswa emikhiqizweni ebhakiwe njengezinkwa, amakhekhe namakhekhe ukuze kuthuthukiswe ukuphatheka kwenhlama, kwandiswe ukugcinwa kwamanzi kanye nokwelula ubusha.

Imikhiqizo yobisi: Emikhiqizweni yobisi efana no-ayisikhilimu neyogathi, i-CMC isebenza njengesiqinisi, ivimbela amakristalu eqhwa ukuthi akheke futhi agcine ukuthungwa.

Amasoso Nezingubo Zokugqoka: I-CMC isebenza njenge-ejenti yokujiya kumasoso nezingubo zokugqoka, idlulisela i-viscosity oyifunayo futhi ithuthukise ikhwalithi iyonke.

Iziphuzo: Isetshenziselwa iziphuzo ukuzinzisa ukumiswa, ukuvimbela ukubola kanye nokuthuthukisa ukunambitheka.

I-Confectionery: I-CMC isetshenziswa ekukhiqizeni i-confectionery ukuhlinzeka ngezakhiwo zokwakha ifilimu ekuhlanganiseni futhi kuvimbele ukugqama kukashukela.

Inyama Ecutshunguliwe: Ezinyameni ezicutshunguliwe, i-CMC isiza ukuthuthukisa ukugcinwa kwamanzi, iqinisekisa umkhiqizo omuncu, omuncu.

Imikhiqizo engenayo iGluten: I-CMC kwesinye isikhathi isetshenziswa kumaresiphi angenayo i-gluten ukulingisa ukuthungwa kanye nesakhiwo esihlinzekwa yi-gluten.

Ukudla Kwezilwane Ezifuywayo: I-CMC iphinde isetshenziswe embonini yokudla kwezilwane ezifuywayo ukuthuthukisa ukuthungwa nokubukeka kokudla kwezilwane ezifuywayo.

Ukucatshangelwa kokuphepha:

I-CMC yebanga lokudla ithathwa njengephephile ukuthi isetshenziswe uma isetshenziswa ngaphakathi kwemikhawulo ethile. Kugunyazwe ama-ejensi alawulayo okuhlanganisa i-US Food and Drug Administration (FDA) kanye ne-European Food Safety Authority (EFSA) njengesithasiselo sokudla esingakhiqizi imiphumela emibi kakhulu uma sisetshenziswa ngokuvumelana Nemikhuba Emihle Yokukhiqiza (GMP).

Kodwa-ke, amazinga okusebenzisa anconyiwe kufanele alandelwe ukuze kuqinisekiswe ukuphepha kokugcina kokudla. Ukusetshenziswa ngokweqile kwe-CMC kungase kubangele ukucasuka kwamathumbu kwabanye abantu. Njenganoma yiziphi izithasiselo zokudla, abantu abangezwani nemizwa ethile noma abangezwani nakho kufanele baqaphele futhi bafune iseluleko sikachwepheshe wokunakekelwa kwezempilo.

Ekuphetheni:

Ibanga lokudla i-sodium carboxymethyl cellulose (CMC) idlala indima ebalulekile embonini yokudla, isiza ukuthuthukisa ukuthungwa, ukuzinza kanye nekhwalithi iyonke yemikhiqizo yokudla ehlukahlukene. Izakhiwo zayo eziyingqayizivele, ezihlanganisa ukuncibilika, ukuguquguquka kwe-viscosity namandla okwenza ifilimu, kuyenza ibe isithako esishintshashintshayo esinezinhlelo zokusebenza ezihlukahlukene. Inqubo yokukhiqiza iqinisekisa ukuhlanzeka nokuphepha kwe-CMC yebanga lokudla, futhi ukugunyazwa okulawulwayo kugcizelela ukufaneleka kwayo ukusetshenziswa ochungechungeni lokuhlinzekwa kokudla. Njenganoma yiziphi izithasiselo zokudla, ukusetshenziswa okunesibopho nokwaziswa kubalulekile ekugcineni ukuphepha komkhiqizo nokwaneliseka kwabathengi.
