Methylcellulose yisengezo sokudla esivamile. Kwenziwa kusuka ku-cellulose yemvelo ngokuguqulwa kwamakhemikhali. Kunokuqina okuhle, ukugcinwa kwezindawo kanye nokuqina futhi kusetshenziswa kabanzi embonini yokudla. Njengento eguqulwe ngobuciko, ukuphepha kwako ekudleni sekuyisikhathi eside bekuyinto ekhathazayo.
1. Izakhiwo nemisebenzi ye-methylcellulose
Ukwakheka kwamangqamuzana kwe-methylcellose kususelwa kuβIyunithi ye-1,4-glucose, eyakhiwa ngokubuyisela amanye amaqembu e-hydroxy ngamaqembu we-methoxy. Kuyancibilika emanzini abandayo futhi kungakha ijeli eliguqukayo ngaphansi kwezimo ezithile. Inokuqina okuhle, ukuqinisekiswa, ukumiswa, ukuqina kanye nezinto zokugcina amanzi. Le misebenzi yenza ukuthi isetshenziswe kabanzi ngesinkwa, amakhekhe, iziphuzo, imikhiqizo yobisi, ukudla okuqandisiwe kanye nezinye izinkambu. Isibonelo, kungathuthukisa ukuthungwa kwenhlama nokubambezeleka kokuguga; ekudleni eqandisiwe, kungathuthukisa ukumelana kwamaqhwa.
Naphezu kwemisebenzi yayo ehlukahlukene, i-methylcellose ngokwayo ayimuzwanga noma ihlukaniswe emzimbeni womuntu. Ngemuva kokumunca, kukhululwe ikakhulukazi ngepheshana lokugaya ukudla ngendlela enobuntu, okwenza umthelela wayo oqondile emzimbeni womuntu ubonakale umkhawulo. Kodwa-ke, lesi sici sivuse futhi ukukhathazeka kwabantu isikhathi eside kungathinta impilo yamathumbu.
2. Izifundo zobumnandi zokuhlola nokuphepha
Izifundo eziningi zobumnandi zikhombisile ukuthi i-methylcellose ine-biocomplute enhle kanye nobuthi obuphansi. Imiphumela yokuhlolwa kobuthi obubi okukhombisa ukuthi i-LD50 yayo (umthamo obulalayo) yayiphakeme kakhulu kunemali esetshenziswa ezingeni ezijwayelekile zokudla, ekhombisa ukuphepha okuphezulu. Ekuhlolweni kobuthi besikhathi eside, amagundane, amagundane nezinye izilwane azange zibonise ukusabela okubucayi ngaphansi kokondla isikhathi eside ngemithamo ephezulu, kufaka phakathi ubungozi obufana ne-carcinogenicity, i-teratogenicity kanye nobuthi bokuzala.
Ngaphezu kwalokho, umphumela we-methylcellose esisekelweni somuntu ubuye watadisha kabanzi. Ngoba akugaywa futhi kugadwe, i-methylcellulose ingakhuphula ivolumu ye-stool, ithuthukise ama-peristalsinal, futhi inezinzuzo ezithile zokunciphisa ukuqunjelwa. Ngasikhathi sinye, akuboshwe yi-flora yamathumbu, ukunciphisa ubungozi bokugcwala noma ubuhlungu besisu.
3. Imithetho kanye nemigomo
Ukusetshenziswa kwe-methylcellose njengesengezo sokudla kulawulwa ngokuphelele emhlabeni wonke. Ngokusho kokuhlolwa kweKomidi Elihlanganyelwe Yezengezo (I-Jecfa) ngaphansi kwenhlangano yokudla nezolimo yeNhlangano Yezizwe (i-FAO) kanye ne-World Health Organisation (WHO), i-Methylcellulose (i-ADI) ye-methylcellulose "ayicaciswanga ", okubonisa ukuthi kuphephile ukusebenzisa ngaphakathi komthamo onconyiwe.
E-United States, i-methylcellose ifakwe kuhlu njengento ebonwa njengokuphephile (GRAS) into ngu-US Food and Drug Administration (FDA). E-European Union, kuhlukaniswa njenge-E461 yokudla okunezela ukudla, nokusetshenziswa kwayo okuphezulu kokudla okuhlukile kuchazwe ngokucacile. E-China, ukusetshenziswa kwe-methylcellose kulawulwa futhi nge- "National Food Pheel standard Okujwayelekile Ukusetshenziswa Okujwayelekile" (GB 2760), okudinga ukulawula okuqinile komthamo ngokuya ngohlobo lokudla.
4. Ukucatshangelwa Kwezokuphepha kuzinhlelo zokusebenza ezisebenzayo
Yize ukuphepha okuphelele kwe-methylcellose kuphezulu kakhulu, ukusetshenziswa kwayo ekudleni kusadinga ukunaka amaphuzu alandelayo:
Umthamo: Ukungezwa ngokweqile kungashintsha ukuthungwa kokudla futhi kuthinte ikhwalithi yemizwa; Ngasikhathi sinye, ukudla okwedlulele kwezinto eziphakeme kakhulu kungadala ukungakhululeki noma ukugaya ukudla emnene yokugaya.
Inani labantu abahlosiwe: Kubantu abanomsebenzi obuthakathaka obusethuli (njengezingane asebekhulile noma abancane), imithamo ephezulu ye-methylcellulose ingadala ukugaya esikhathini esifushane, ngakho-ke kufanele ikhethwe ngokuqapha.
Ukuxhumana nezinye izithako: Kwezinye izindlela zokudla, ama-methylcellose angaba nomphumela wokuvumelanisa nezinye izithasiselo noma izithako, nemiphumela yazo ehlanganisiwe kudingeka kubhekwe.
5. Isifinyezo kanye ne-Outlook
Ngenjwayelo,methylcellulose Ingabe isengezo sokudla esiphephile nesisebenzayo esingeke sibangele ukulimala okubalulekile empilweni yabantu ngaphakathi kwehlu elifanelekile lokusebenzisa. Izakhiwo zalo ezingezona ezingase zibe zingenakukwenza zizinze ngendlela eshintshayo yokugaya ukudla futhi zingaletha izinzuzo ezithile zezempilo. Kodwa-ke, ukuze uphinde uqinisekise ukuphepha kwayo ekusetshenzisweni kwesikhathi eside, kuyadingeka ukuqhubeka nokunaka izifundo ezifanele ze-anobuthi kanye nedatha yohlelo lokusebenza olusebenzayo, ikakhulukazi umthelela wawo kubantu abakhethekile.
Ngokuthuthukiswa komkhakha wokudla kanye nokwenza ngcono ukufunwa kwabathengi ngekhwalithi yokudla, ubukhulu bokusebenzisa i-methylcellulose bungandiswa. Esikhathini esizayo, izicelo ezintsha kakhulu kufanele zihlolwe esibonelweni sokuqinisekisa ukuphepha kokudla ukuletha inani elikhudlwana embonini yokudla.
