I-Cellulose gum, eyaziwa nangokuthii-carboxymethylcellulose(CMC), iyisengezo sokudla esivame ukusetshenziswa embonini yokudla njenge-thickener, stabilizer, kanye ne-emulsifier. Isuselwa ku-cellulose, i-polymer yemvelo etholakala ezitshalweni, futhi isetshenziswa kakhulu emikhiqizweni yokudla ehlukahlukene, okuhlanganisa izimpahla ezibhakiwe, imikhiqizo yobisi, iziphuzo, namasoso. Kulesi sihloko, sizobhekisisa inhlaka ye-cellulose, izici zayo, ukusetshenziswa kwayo, ukuphepha, kanye nezingozi ezingaba khona.

Izakhiwo kanye Nokukhiqizwa kwe-Cellulose Gum

I-Cellulose gum iyi-polymer encibilika emanzini etholakala ku-cellulose. Yenziwa ngokwelapha i-cellulose ngekhemikhali ebizwa ngokuthi i-monochloroacetic acid, eyenza i-cellulose ibe i-carboxymethylated. Lokhu kusho ukuthi amaqembu e-carboxymethyl (-CH2-COOH) engezwa kumgogodla we-cellulose, okuwunikeza izakhiwo ezintsha njengokunyuka kokuncibilika emanzini kanye namakhono athuthukisiwe okubopha kanye nokuqina.

I-Cellulose gum iyimpushana emhlophe ukuya kokumhlophe engenaphunga futhi ayinambitheki. Incibilika kakhulu emanzini, kodwa ayincibiliki kuzincibilikisi eziningi eziphilayo. Ine-viscosity ephezulu, okusho ukuthi inamandla okujiyisa uketshezi, futhi yenza ama-gel phambi kwama-ion athile, njenge-calcium. I-viscosity kanye ne-gel-forming properties ye-cellulose gum ingalungiswa ngokushintsha izinga le-carboxymethylation, elithinta inani lamaqembu e-carboxymethyl kumgogodla we-cellulose.

Ukusetshenziswa kwe-Cellulose Gum ekudleni

I-Cellulose gum iyisengezo sokudla esisebenza ngezindlela eziningi esisetshenziswa emikhiqizweni eminingi yokudla ukuze kuthuthukiswe ukuthungwa kwayo, ukuzinza nokubukeka kwayo. Ngokuvamile isetshenziswa njenge-thickener, stabilizer, kanye ne-emulsifier ezimpahleni ezibhakwayo njengesinkwa, amakhekhe, namakhekhe, ukuze kuthuthukiswe ukuthungwa kwazo futhi kwandiswe impilo yazo yeshalofu. Emikhiqizweni yobisi efana neyogathi, u-ayisikhilimu, noshizi, isetshenziselwa ukuthuthukisa ukuthungwa kwazo, ukuvimbela ukuhlukana, nokwandisa ukuzinza. Eziphuzweni ezifana neziphuzo ezibandayo namajusi, isetshenziselwa ukuzinzisa uketshezi nokuvimbela ukuhlukana.

I-Cellulose gum ibuye isetshenziswe kumasoso, okokugqoka, kanye nezinongo ezifana ne-ketchup, imayonnaise, kanye nesinaphi, ukuze zijiye futhi zithuthukise ukubukeka kwazo. Isetshenziswa emikhiqizweni yenyama efana namasoseji kanye nama-meatballs, ukuze kuthuthukiswe izakhiwo zabo zokubopha futhi kuvimbele ukuthi zingaqhekeki ngesikhathi sokupheka. Ibuye isetshenziswe ekudleni okunamafutha aphansi kanye nama-calorie ancishisiwe, ukufaka esikhundleni samafutha futhi kuthuthukise ukuthungwa.

Ukuphepha kwe-Cellulose Gum ekudleni

I-Cellulose gum icutshungulwe kabanzi ngokuphepha kwayo ekudleni, futhi itholakale iphephile ukuthi isetshenziswe abantu emazingeni asetshenziswa emikhiqizweni yokudla. I-Joint FAO/WHO Expert Committee on Food Additives (JECFA) isungule ukudla okwamukelekayo kwansuku zonke (i-ADI) ka-0-25 mg/kg wesisindo somzimba we-cellulose gum, okuyinani leshungu ye-cellulose engadliwa nsuku zonke empilweni yonke. ngaphandle kwanoma yimiphi imiphumela emibi.

Ucwaningo luye lwabonisa ukuthi i-cellulose gum ayiyona into enobuthi, i-carcinogenic, i-mutagenic, noma i-teratogenic, futhi ayidali noma yimiphi imiphumela emibi ohlelweni lokuzala noma ukukhula. Ayinametabolism ngumzimba futhi ikhishwa ingashintshiwe endle, ngakho ayiqoqi emzimbeni.

Kodwa-ke, abanye abantu bangase babe nokungezwani komzimba ne-cellulose gum, okungabangela izimpawu ezinjengokuqubuka, ukulunywa, ukuvuvukala, nokuphefumula kanzima. Lokhu kusabela akuvamile kodwa kungaba kubi kwezinye izimo. Uma uba nanoma iyiphi yalezi zimpawu ngemva kokudla umkhiqizo wokudla oqukethe izinhlaka ze-cellulose, kufanele ufune usizo lwezokwelapha ngokushesha.
