I-Sodium Carboxymethyl Cellulose (CMC)iwumkhiqizo wemvelo oguqulwe ngamakhemikhali, osetshenziswa kabanzi embonini yokudla, yezemithi kanye neyekhemikhali yansuku zonke. I-CMC yezinga lokudla, njengohlobo lwe-polymer colloid, idlala indima enkulu yokuqina, ukuzinza, ukugcinwa kwamanzi, ukuhlanganiswa kwe-emuls kanye nokwakheka kwefilimu embonini yokudla. Ngenxa yokuphepha kwayo okuhle kakhulu kanye nezakhiwo zayo zokusebenza ezivelele, i-CMC isibe ngenye yezinto ezivuthiwe kakhulu ze-polysaccharide ezisetshenziswa ezithasiselweni zokudla.
1. Ukuhlaziywa kokuphepha kwe-CMC yezinga lokudla
I-CMC yezinga lokudla yenziwe nge-cellulose yezitshalo zemvelo njengezinto zokusetshenziswa futhi ikhiqiza imikhiqizo ye-carboxymethylated ngokusebenzisa ukusabela kwe-etherification. Isakhiwo sayo sizinzile futhi asimuncwa kalula futhi asigaywa umzimba womuntu, ngaleyo ndlela sibe nokuphepha okuphezulu ngokomzimba. Kokubili i-World Health Organization (WHO) kanye ne-Food and Agriculture Organization yeZizwe Ezihlangene (FAO) bafake i-CMC ohlwini "lwezithasiselo zokudla eziphephile zokusetshenziswa", kanti i-Codex Alimentarius Commission nayo yenze imithetho ecacile ngobumsulwa bayo kanye nobubanzi bokusetshenziswa kwayo.
Ngokuphathelene nocwaningo lwe-toxicological, inani elikhulu lemiphumela yokuhlola likhombisile ukuthi i-CMC ayinayo ubuthi obukhulu, ayinazo izinguquko emzimbeni, ayinazo i-teratogenicity, futhi ayikho imiphumela ecacile yomzimba ezithweni zezilwane noma zabantu etholakele. I-CMC empeleni ayimuncwa emzimbeni futhi ikhishwa kakhulu ngesimo sayo sokuqala, ngakho-ke ayibangeli umthwalo we-metabolic noma iqoqe ubuthi. I-FDA yase-United States iyibeke njenge-GRAS (Ngokuvamile Eyaziwa Njengephephile, ngokuvamile ebhekwa njengephephile), okuvumela ukuthi isetshenziswe kabanzi ekudleni.
I-CMC yezinga lokudla inokulawula okuqinile izinsalela zezinsimbi ezisindayo, ama-chloride kanye nezinyibilikisi eziphilayo ngesikhathi sokukhiqizwa. Ubumsulwa bayo buvame ukuba ngaphezu kwama-99% futhi iye yahlolwa ngokujulile amazinga okuhlanzeka. Uma nje isetshenziswa ngaphakathi kobubanzi obubekiwe kanye nomthamo onqunyiwe yisifundazwe noma emhlabeni jikelele, ukumuncwa kwe-CMC kuphephile ngokuphelele.
2. Izici zokusebenza ze-CMC yezinga lokudla
2.1. Imiphumela yokujiya nokuzinzisa
I-molecule ye-CMC iqukethe inani elikhulu lamaqembu e-carboxymethyl kanye ne-hydroxyl, angakha izibopho eziqinile ze-hydrogen nama-molecule amanzi futhi abonise i-hydrophilicity ebalulekile kanye nempahla yokuvuvukala. Ezinhlelweni zokudla, noma ngabe ingezwe ngamanani aphansi, ingakhulisa kakhulu i-viscosity yesistimu, yakhe isakhiwo soketshezi esifanayo, ngaleyo ndlela ithuthukise ukunambitheka kanye nokuthungwa komkhiqizo. Okwamanje, i-CMC inokuqina okuhle kakhulu kwe-ionic futhi ingagcina ukuqina kwe-viscosity ezindaweni ezine-acidic, alkaline noma ezinosawoti omningi. Ivame ukusetshenziswa emikhiqizweni yobisi, eziphuzweni zejusi yezithelo kanye nezinongo ukuvimbela ukuqhekeka kanye nokuna kwemvula.
2.2. Izakhiwo zokugcina amanzi kanye nokuvimbela imvula
I-CMC ingahlangana ngempumelelo nomswakama, inciphise ukufuduka komswakama kanye nokuqandisa ukudla ngesikhathi sokugcina noma ukuqandisa. Isibonelo, ekudleni okuqandisiwe kanye nezimpahla ezibhakiwe, isici sokugcina amanzi se-CMC singavimbela ukuqhekeka nokuqina, sandise isikhathi sokuphila eshalofini, futhi sigcine ukuthamba kanye nokusha kwemikhiqizo.
2.3. Izakhiwo ze-emulsification kanye nokumiswa
I-CMC ingakha ifilimu e-viscoelastic endaweni yokuhlangana namanzi kawoyela, ithuthukise ukuzinza kohlelo lwe-emulsification futhi ivimbele uwoyela ukuthi ungantanti noma uhlukaniswe. Ngakho-ke, ivame ukusetshenziswa emikhiqizweni efana ne-ayisikhilimu, izithasiselo zesaladi, kanye neziphuzo zobisi, isebenza ngokubambisana nama-emulsifier ukuze kufezwe ukuthungwa okuhle nokuzinzile.
2.4.. Izakhiwo zokwakha amafilimu kanye nokumboza
I-CMC inezakhiwo ezinhle kakhulu zokwakha ifilimu futhi ingakha ifilimu ecacile phezu kokudla. Isetshenziselwa ukumboza izithelo, amaswidi noma izimpushana ezisheshayo, idlala indima ekuvimbeleni umswakama, ekulweni ne-oxidation kanye nokubambezeleka kokuwohloka. Kumpushana weziphuzo ezisheshayo kanye nempushana yokunambitha, i-CMC ingavimbela nokugaywa futhi ithuthukise ukuncibilika.
2.5. Thuthukisa ukunambitheka kanye nokuthungwa
I-CMC inganika ukudla ukuthungwa okubushelelezi nokujiyile futhi ithuthukise izakhiwo ze-rheological zomkhiqizo. Isibonelo, ku-yogurt kanye ne-jelly, i-CMC ingandisa ukuminyana, inike isakhiwo esihle sokuthungwa futhi ithuthukise ulwazi lokunambitha kwabathengi.
3. Amasimu okusetshenziswa kwe-CMC yezinga lokudla
Isigaba seziphuzo: Vimbela ukubola kanye nokuhlukaniswa kwezinhlobo zeziphuzo zejusi yezithelo kanye neziphuzo zamaprotheni, futhi uthuthukise ukugeleza nokunambitheka.
Imikhiqizo yobisi: Isetshenziswa ku-ayisikhilimu kanye ne-yogurt ukuthuthukisa ukuhambisana nokuvimbela ukwakheka kwe-ice crystal, ukuthuthukisa ukushelela kwekhwalithi yobisi.
Izinto ezibhakiwe: Thuthukisa ukugcinwa kwamanzi kanye nokuqina kokuthungwa kwenhlama esinkweni nasemaqebelengwaneni, futhi wandise isikhathi sokuthamba.
Izinongo kanye nesoso yesoya: Vimbela uwoyela namanzi ukuthi angahlukani, kuthuthukisa ukukhazimula nokunamathela odongeni.
Amaswidi nokudla okusheshayo: Njenge-ejenti yokumboza kanye ne-ejenti yokulwa nokubhakwa, ithuthukisa ukubukeka nokuncibilika.
I-CMC yezinga lokudlaiyi-polysaccharide yemvelo ephephile, ethembekile futhi esebenza ngokugcwele. Izakhiwo zayo ezinhle kakhulu zokuqina, ukuzinza, ukugcina amanzi, ukuhlanganisa kanye nokwenza ifilimu zenza ukuthi ibambe isikhundla esingenakuguqulwa embonini yokudla yanamuhla. Ngokombono wokuphepha, i-CMC iqinisekiswe yizikhungo eziningi ezigunyaziwe emhlabeni jikelele futhi iqashelwa njengesithako sokudla esingenabo ubuthi, esingenalo i-allergies, futhi esingasetshenziswa isikhathi eside. Njengoba ukukhathazeka kwabantu ngekhwalithi yokudla kanye nempilo kuqhubeka nokukhula, amasimu okusetshenziswa kwe-CMC yezinga lokudla azokhula kakhulu, futhi izinzuzo zayo zokusebenza kumalebula ahlanzekile, ukudla okunamafutha aphansi kanye nemikhiqizo esekelwe ezitshalweni nazo zizoqhubeka nokubonakaliswa.
