I-Methylcellulose ingase ingabi igama lasekhaya, kodwa iyi-polymer eguquguqukayo enezicelo eziningi zezimboni nezokupheka. Izakhiwo zayo zamakhemikhali eziyingqayizivele ziyenza ibe yimpahla efanelekile yokusetshenziswa okubanzi, kusukela kumasoso aqinayo kuya ekudaleni izimbotshana zemithi. Kodwa okwenza i-methylcellulose ihluke kwezinye izinto amandla ayo okumelana nawo womane amasizini.
Ngaphambi kokuthi singene kwisayensi engemuva kwe-methylcellulose, ake siqale sixoxe ngokuthi iyini nokuthi ivelaphi. I-Methylcellulose iwuhlobo lwe-cellulose ether etholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. I-Cellulose ingenye yezakhi eziphilayo ezitholakala ngobuningi eMhlabeni futhi itholakala emithonjeni eminingi yezitshalo ehlukene, okuhlanganisa ukhuni, ukotini noqalo. I-Methylcellulose yenziwa ngokushintsha i-cellulose amakhemikhali ngamaqembu e-methyl, eshintsha izakhiwo zayo futhi iyenze incibilike kakhulu emanzini.
Manje, ake sikhulume ngokuthi yini eyenza i-methylcellulose yangempela ikhetheke kangaka. Enye yezinto ezihluke kakhulu ze-methylcellulose yikhono layo lokwenza ijeli lapho ihlangana namanzi. Lokhu kugeleza kwenzeka ngoba amaqembu e-methyl kuma-molecule e-cellulose akha umgoqo we-hydrophobic oxosha ama-molecule amanzi. Ngakho-ke lapho i-methylcellulose yengezwa emanzini, yenza into efana nejeli engasetshenziswa ukujiyisa izixazululo, ukwenza amafilimu, ngisho nokwenza ama-noodle adliwayo.
Kodwa okwenza ngempela i-methylcellulose ihluke yikhono layo lokumelana nemiphumela yazo zozine izinkathi zonyaka. Lokhu kungenxa yokuziphatha kwayo okuyingqayizivele emazingeni okushisa ahlukene. Emazingeni okushisa aphansi, njengasebusika, i-methylcellulose yangempela yakha ijeli eliqinile neliqinile. Lokhu kuyenza ibe yinto ekahle yokwakha izimbotshana zemithi neminye imikhiqizo edinga ukuvikelwa kumswakama nezinye izici zemvelo.
Kodwa-ke, njengoba izinga lokushisa likhuphuka, i-methylcellulose yangempela izoqala ukuthamba futhi ibe lula. Lokhu kungenxa yokuthi njengoba amazinga okushisa enyuka, isithiyo se-hydrophobic esidalwe amaqembu e-methyl sisebenza kancane ekuxosheni ama-molecule amanzi. Ngenxa yalokho, isisindo esifana nejeli esikhiqizwe i-methylcellulose siyancipha futhi siphenduleka, okwenza kube lula ukubumba nokubunjwa.
Ngesikhathi sasehlobo, i-methylcellulose yangempela iba lula ukuphenduleka, okuyenza ibe yinto enhle kakhulu yokwenza imikhiqizo edliwayo efana nemifino kanye ne-vegan esikhundleni senyama. Ingasetshenziswa futhi njenge-agent yokuqina kumasoso kanye nesobho ngoba ihlala izinzile ngisho namazinga okushisa aphezulu.
Enye yezinzuzo ezibaluleke kakhulu ze-methylcellulose yangempela ikhono layo lokuhlala uzinzile ngokuhamba kwesikhathi. Ngokungafani nezinye izinto ezingase zilulaze noma ziwohloke ngokuhamba kwesikhathi, i-methylcellulose yangempela izogcina izakhiwo zayo iminyaka, iyenze ibe yinto ekahle yokusetshenziswa isikhathi eside. Lokhu kubaluleke kakhulu ezimbonini ezifana nemithi kanye nezimonyo, lapho imikhiqizo idinga ukugcina ukusebenza kwayo kanye namandla esikhathini eside.
Enye inzuzo ye-methylcellulose yangempela ukuphepha kwayo nokuguquguquka. Ihlukaniswa yi-FDA njengevame ukuqashelwa njengephephile (GRAS), okusho ukuthi ibhekwa njengephephile ukuthi isetshenziswe futhi isetshenziswe ekudleni, ezidakamizweni, nasezintweni zokugcoba. Futhi ayinabo ubuthi futhi iyabola, okuyenza ibe ukukhetha okulungele imvelo.
Ngaphezu kokusetshenziswa kwayo okuningi kwezimboni, i-methylcellulose yangempela nayo isetshenziswa emkhakheni wokupheka. Eqinisweni, kuyisithako esidumile ezitsheni eziningi ze-vegan nemifino ngenxa yekhono layo lokudala into efana nejeli ngaphandle kokusebenzisa imikhiqizo yezilwane. Ivamise ukusetshenziselwa ukwenza ezinye izindlela zenyama esekwe ezitshalweni kanye nezimpahla ezibhakiwe nama-dessert.
Sengiphetha, i-methylcellulose yeqiniso iyimpahla ephakeme enezinzuzo eziningi ngaphezu kwamanye ama-polymer. Ikhono layo lokumelana nawo wonke amasizini amane, igcine uzinzo ngokuhamba kwesikhathi, nokuhlala iphephile futhi iguquguqukayo iyenza ilungele izimboni eziningi. Kungakhathaliseki ukuthi isetshenziswa ekukhiqizweni kwemithi, izimonyo noma ukudla okusekelwe ezitshalweni, i-methylcellulose yangempela iyinto eyingqayizivele esele izohlala.
