I-E466 Isengezo Sokudla - I-Sodium Carboxymethyl Cellulose

I-Sodium Carboxymethyl Cellulose(SCMC) iyisengezo esivamile sokudla esisetshenziswa ezinhlobonhlobo zemikhiqizo yokudla, okuhlanganisa izimpahla ezibhakiwe, imikhiqizo yobisi, iziphuzo, namasoso. Ibuye isetshenziswe kwezinye izimboni, njengemithi, izimonyo, nokukhiqiza amaphepha. Kulesi sihloko, sizobhekisisa i-SCMC, izakhiwo zayo, ukusetshenziswa, ukuphepha, kanye nezingozi ezingaba khona.

Izakhiwo kanye Nokukhiqizwa kwe-SCMC

I-Sodium Carboxymethyl Cellulose iphuma ku-cellulose, okuyi-polymer eyenzeka ngokwemvelo eyakhiwe amayunithi eglucose. I-SCMC yenziwa ngokwelapha i-cellulose ngekhemikhali ebizwa ngokuthi i-monochloroacetic acid, eyenza i-cellulose ibe yi-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-SCMC iyimpushana emhlophe ukuya kokumhlophe engenaphunga futhi engenambitheki. 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-SCMC ingalungiswa ngokushintsha izinga le-carboxymethylation, elithinta inani lamaqembu e-carboxymethyl kumgogodla we-cellulose.

Ukusetshenziswa kwe-SCMC Ekudleni

I-SCMC isetshenziswa kakhulu embonini yokudla njengesengezo sokudla, ikakhulukazi njengesishuqululi, isiqinisi, kanye ne-emulsifier. Ivamise ukusetshenziswa ezimpahleni ezibhakwayo njengesinkwa, amakhekhe, namakhekhe, ukuze kuthuthukiswe ukuthungwa kwazo, kwandise isikhathi sazo seshelufu, futhi kuvinjwe ukuthi zingami. 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-SCMC iphinde isetshenziswe kumasoso, okokugqoka, kanye nama-condiments afana ne-ketchup, imayonnaise, nesinaphi, ukuze kushube futhi kuthuthukiswe ukuthungwa 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.

I-SCMC ngokuvamile ibhekwa njengephephile ukusetshenziswa ekudleni yizinhlangano ezilawulayo emhlabeni jikelele, okuhlanganisa i-US Food and Drug Administration (FDA) kanye ne-European Food Safety Authority (EFSA).

Ukuphepha kwe-SCMC ekudleni

I-SCMC ifundwe 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 (ADI) kwesisindo somzimba esingu-0-25 mg/kg se-SCMC, okuyinani le-SCMC elingadliwa nsuku zonke empilweni yonke ngaphandle imiphumela emibi.

Ucwaningo lubonise ukuthi i-SCMC ayinabo ubuthi, 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-SCMC, okungabangela izimpawu ezinjengokuqubuka, ukulunywa, ukuvuvukala, kanye nobunzima bokuphefumula. Lokhu kusabela akuvamile kodwa kungaba kubi kwezinye izimo. Uma uhlangabezana nanoma iyiphi yalezi zimpawu ngemva kokudla umkhiqizo wokudla oqukethe i-SCMC, wena kudokotela wakho ngokushesha.

Izingozi ezingaba khona ze-SCMC

Nakuba i-SCMC ngokuvamile ibhekwa njengephephile ukuze isetshenziswe abantu, kunezingozi ezingaba khona ezihlobene nokusetshenziswa kwayo. Okunye okukhathaza kakhulu umphumela wawo ohlelweni lokugaya ukudla. I-SCMC iyifayibha encibilikayo, okusho ukuthi ingamunca amanzi futhi yakhe into efana nejeli emathunjini. Lokhu kungase kubangele izinkinga zokugaya ukudla okufana nokuqunjelwa, igesi, nesifo sohudo kwabanye abantu, ikakhulukazi uma kusetshenziswe amanani amakhulu.

Enye ingozi engaba khona umphumela wawo ekumunceni izakhi. Ngenxa yokuthi i-SCMC ingenza into efana nejeli emathunjini, ingase iphazamise ukumuncwa kwezakhi ezithile, ikakhulukazi amavithamini ancibilikayo kumafutha afana no-A, D, E, no-K. Lokhu kungase kuholele ekuntulekeni kwezakhi ngokuhamba kwesikhathi, ikakhulukazi uma isetshenziswe ngamanani amakhulu njalo.

Kuyaqapheleka futhi ukuthi ezinye izifundo ziphakamise ukuthi i-SCMC ingaba nomthelela omubi empilweni yamathumbu. Ucwaningo olushicilelwe ephephabhukwini I-Nature Communications ngo-2018 lwathola ukuthi i-SCMC ingaphazamisa ibhalansi yamagciwane amathumbu kumagundane, okungaholela ekuvuvukeni nakwezinye izinkinga zezempilo. Nakuba ucwaningo olwengeziwe ludingeka ukuze kuqondwe ngokugcwele umthelela we-SCMC empilweni yamathumbu kubantu, lena indawo yokukhathazeka okufanele iqashwe.

Isiphetho

I-Sodium Carboxymethyl Cellulose iyisengezo sokudla esisetshenziswa kabanzi esithathwa njengephephile ukuthi sisetshenziswe abantu. Isetshenziswa ngokuyinhloko njenge-thickener, stabilizer, kanye ne-emulsifier ezinhlobonhlobo zemikhiqizo yokudla, okuhlanganisa izimpahla ezibhakiwe, imikhiqizo yobisi, iziphuzo, namasoso. Yize kunezingozi ezingaba khona ezihlobene nokusetshenziswa kwayo, ikakhulukazi ngamanani amakhulu, ukuphepha kukonke kwe-SCMC kusungulwe ama-ejensi alawulayo emhlabeni jikelele.

Njenganoma yisiphi isithasiselo sokudla, kubalulekile ukusebenzisa i-SCMC ngokulinganisela futhi uqaphele noma yikuphi ukuzwela okungaba khona noma ukungezwani komzimba nezinto ezithile. Uma unokukhathazeka mayelana nokusetshenziswa kwe-SCMC emikhiqizweni yokudla, thintana nodokotela wakho noma isazi sokudla esibhalisiwe.
