I-methylcellose kungenzeka ingabi yigama lendlu, kepha iyisidlali esiguquguqukayo esinezicelo eziningi zezimboni nezesiko. Izakhiwo zayo ezihlukile zamakhemikhali zikwenza kube yinto efanelekile yohlobo olunhlobonhlobo lokusetshenziswa, kusuka kusoso oluqinile lokwakha izimbobo zemithi. Kepha okusetha i-methylcellose ngaphandle kwalokhu okuhlukile kwezinye izinto amandla awo okumelana nazo zonke izinkathi ezine.
Ngaphambi kokuthi singene kwisayensi ngemuva kwe-methylcellose, ake siqale sixoxe ngokuthi siyini nokuthi sivelaphi. I-Methylcellose uhlobo lwe-cellulose ether ethathwe ku-cellulose, i-polymer yemvelo etholakala ezindongeni zeseli zezitshalo. I-cellulose ingenye yezindlela eziningi ze-organic emhlabeni futhi zitholakala emithonjeni eminingi yezitshalo ehlukene, kufaka phakathi ipulpiti yezinkuni, ukotini kanye noqalo. I-Methylcellose yenziwa ngokuguqula amakhemikhali ama-cellulose ngamaqembu we-methyl, aguqula izakhiwo zawo futhi akwenze kuncibilike kakhulu emanzini.
Manje, ake sixoxe ngalokho okwenze i-methylcellose yangempela ekhethekile. Enye yezinto ezihlukile kakhulu ze-methylcellulose yikhono layo ukwakha ijeli lapho lihlangana namanzi. Le gelation yenzeka ngoba amaqembu we-methyl kuma-molecule we-cellulose akha isithiyo se-hydrophobic esixosha ama-molecule amanzi. Ngakho-ke lapho i-methylcellose inezelwa emanzini, yakha into efana negeyimu engasetshenziselwa ukukhumula izixazululo, zamafilimu, futhi yenze nama-noodle adliwayo.
Kepha okubeka ngokweqiniso ngokweqiniso kwe-methylcellose yikhono layo lokumelana nemiphumela yazo zonke izinkathi ezine. Lokhu kungenxa yokuziphatha kwayo okuyingqayizivele emazingeni okushisa ahlukene. Emazingeni okushisa aphansi, njengasebusika, i-methylcellose yangempela yakha ijeli eqinile nelukhuni. Lokhu kwenza kube yinto ekahle yokwakha izimbotshana zemithi yemithi neminye imikhiqizo edinga ukuvikeleka kumswakama nakwezinye izinto zemvelo.
Kodwa-ke, njengoba izinga lokushisa likhuphuka, i-methylcellose yangempela izoqala ukuthambisa futhi ibekezele kakhulu. Lokhu kungenxa yokuthi njengoba amazinga okushisa akhuphuka, isithiyo se-hydrophobic esakhiwe ngamaqembu we-methyl sisebenza kangako lapho kuphazamisa ama-molecule amanzi. Ngenxa yalokhu, isisindo esifana ne-gel-efana ne-methylcellulose siba nzima futhi silinganise ngokwengeziwe, okwenza kube lula ukubumba nokuma.
Ngesikhathi sasehlobo, i-methylcellulose yangempela isebenza ngokwengeziwe, okwenza kube yinto enhle kakhulu yokwenza imikhiqizo edliwayo njengenye yezindawo zemifino kanye ne-vegan yenyama. Ingasetshenziswa futhi njenge-ejenti yokuqina kusoso kanye nesobho ngoba ihlala iqinile ngisho nasemazingeni okushisa aphezulu.
Enye yezinzuzo ezibaluleke kakhulu ze-merylcellulose yangempela yikhono lazo lokuhlala uzinzile ngokuhamba kwesikhathi. Ngokungafani nezinye izinto ezingenzakala noma zehle ngokuhamba kwesikhathi, i-methylcellose yangempela izogcina izakhiwo zayo iminyaka, okwenza kube yinto efanelekile yokusetshenziswa kwesikhathi eside. Lokhu kubaluleke kakhulu ezimbonini ezinjengezimboni ezinjengemithi kanye nezimonyo, lapho imikhiqizo idinga ukugcina ukusebenza kwayo kanye ne-poutency ngokuhamba kwesikhathi eside.
Enye inzuzo ye-methylcellulose yangempela ukuphepha kwayo kanye nokuguquguquka okuhlukahlukene. Ihlukaniswe yi-FDA njengoba imvamisa yamukelwa njenge-Safe (GRAS), okusho ukuthi kubhekwa njengephephile ukuze isetshenziswe futhi isetshenziswe ekudleni, kwezidakamizwa, kanye nezimonyo. Futhi ayinangozi futhi inobuthi, okwenza kube ukukhetha okunobungane kwemvelo.
Ngaphezu kwemali yayo eminingi yezimboni, i-methylcellulose yangempela nayo isetshenziswa emkhakheni we-Culinary. Eqinisweni, kuyisithako esidumile ezitsheni eziningi ze-vegan kanye nezitshalo zemifino ngenxa yekhono layo lokwenza into efana negel ngaphandle kokusebenzisa imikhiqizo yezilwane. Imvamisa isetshenziselwa ukudala ezinye izindlela zenyama ezisuselwa kwezitshalo kanye nezimpahla ezibhakiwe kanye nama-dessert.
Ekuphetheni, i-methylcellulose yeqiniso iyinto ephakeme ephakeme enezinzuzo eziningi ngaphezu kwamanye ama-polymers. Ikhono layo lokumelana nazo zonke izinkathi ezine, gcina ukuqina ngokuhamba kwesikhathi, futhi uhlale uphephile futhi oguquguqukayo wenza kube ngcono kwizimboni eziningi. Noma ngabe kusetshenziswe ekukhiqizweni kwemithi, izimonyo noma ukudla okususelwa kwisitshalo, i-methylcellulose yeqiniso, into eyingqayizivele yinto ehlukile lapha yokuhlala.
