I-Methylcellulose ayinakuba ligama lekhaya, kodwa iyipolymer eguquguqukayo enezicelo ezininzi zoshishino kunye nezokupheka. Iimpawu zayo zeekhemikhali ezikhethekileyo zenza ukuba ibe yinto efanelekileyo yokusetyenziswa koluhlu olubanzi, ukusuka kwiisosi ezityebileyo ukuya ekudaleni iingubo zamayeza. Kodwa eyona nto yohlula i-methylcellulose kwezinye izinto kukukwazi kwayo ukumelana nawo omane amaxesha onyaka.
Ngaphambi kokuba singene kwisayensi emva kwe-methylcellulose, masiqale sixoxe ukuba yintoni kwaye ivela phi. I-Methylcellulose luhlobo lwe-cellulose ether ephuma kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zezityalo. I-Cellulose yenye yezona zinto zininzi zekhompawundi ze-organic emhlabeni kwaye ifumaneka kwimithombo emininzi eyahlukeneyo yezityalo, kubandakanya ipulp yomthi, umqhaphu kunye ne-bamboo. I-Methylcellulose yenziwe ngokuguqulwa kweekhemikhali i-cellulose kunye namaqela e-methyl, eguqula iimpawu zayo kwaye iyenze i-soluble ngakumbi emanzini.
Ngoku, makhe sithethe ngento eyenza ukuba i-methylcellulose yokwenyani ikhetheke. Enye yezona zinto zibalaseleyo ze-methylcellulose kukukwazi ukwenza ijeli xa idibana namanzi. Le gelation yenzeka ngenxa yokuba amaqela e-methyl kwiimolekyuli ze-cellulose enza umqobo we-hydrophobic ogxotha iimolekyuli zamanzi. Ke xa i-methylcellulose yongezwa emanzini, yenza into efana nejeli enokuthi isetyenziswe ukujiya izisombululo, ukwenza iifilimu, kunye nokwenza ii-noodles ezityiwayo.
Kodwa eyona nto yahlula i-methylcellulose kukukwazi ukumelana neziphumo zawo omane onyaka. Oku kungenxa yokuziphatha kwayo okungaqhelekanga kumaqondo obushushu ahlukeneyo. Kwiqondo lokushisa eliphantsi, njengasebusika, i-methylcellulose yangempela yenza i-gel eyomeleleyo kwaye enzima. Oku kwenza kube yinto efanelekileyo yokudala iingubo zamachiza kunye nezinye iimveliso ezifuna ukukhuselwa kumswakama kunye nezinye izinto zokusingqongileyo.
Nangona kunjalo, njengoko iqondo lokushisa linyuka, i-methylcellulose yokwenyani iya kuqala ukuthamba kwaye ibe yinto ethambileyo. Oku kungenxa yokuba njengoko amaqondo obushushu enyuka, isithintelo se-hydrophobic esenziwe ngamaqela e-methyl sisebenza kancinci ekugxotheni iimolekyuli zamanzi. Ngenxa yoko, ubunzima obufana nejel obuveliswa yi-methylcellulose buba buqina kwaye bube lula, okwenza kube lula ukubumba kunye nokubumba.
Ngexesha lasehlotyeni, i-methylcellulose yokwenyani iba yinto ethambileyo, iyenza ibe yeyona nto ibalaseleyo yokwenza iimveliso ezityiwayo ezifana nemifuno kunye ne-vegan yenyama. Isenokusetyenziswa njenge-ejenti yokuqina kwiisosi kunye neesuphu kuba ihlala izinzile nakwiqondo lokushisa eliphezulu.
Enye yeenzuzo ezibalulekileyo ze-methylcellulose yokwenyani kukukwazi ukuhlala uzinzile ngokuhamba kwexesha. Ngokungafaniyo nezinye izinto ezinokuthi zithobe okanye ziphule ngokuhamba kwexesha, i-methylcellulose yangempela iya kugcina iimpawu zayo iminyaka, iyenze ibe yinto efanelekileyo yokusetyenziswa kwexesha elide. Oku kubaluleke kakhulu kumashishini afana namayeza kunye nezithambiso, apho iimveliso kufuneka zigcine ukusebenza kwazo kunye namandla kwixesha elide.
Enye inzuzo ye-methylcellulose yokwenyani kukhuseleko kunye nokuguquguquka kwayo. Ihlelwa yi-FDA njengeyaziwa ngokubanzi njengekhuselekile (GRAS), okuthetha ukuba ithathwa njengekhuselekile ukuba ingasetyenziswa kwaye isetyenziswe ekutyeni, kumachiza nakwizithambiso. Kananjalo ayinayo ityhefu kwaye iyabola, iyenza ibe lukhetho oluhambelana nokusingqongileyo.
Ukongeza kwizinto ezininzi ezisetyenziswa kwimizi-mveliso, i-methylcellulose yokwenyani ikwasetyenziswa kwintsimi yokupheka. Ngapha koko, sisithako esithandwayo kwizitya ezininzi ze-vegan kunye nemifuno ngenxa yokukwazi ukwenza into efana nejeli ngaphandle kokusetyenziswa kweemveliso zezilwanyana. Ihlala isetyenziselwa ukwenza enye inyama esekwe kwisityalo kunye nezinto ezibhakiweyo kunye nezimuncumuncu.
Ukuqukumbela, i-methylcellulose yokwenyani yinto ephezulu kunye nezibonelelo ezininzi kunezinye iipolymers. Ukukwazi kwayo ukumelana nawo onke amaxesha onyaka, ukugcina uzinzo ngokuhamba kwexesha, kwaye ihlale ikhuselekile kwaye iguquguquka iyenza ilunge kumashishini amaninzi. Nokuba isetyenziswa kwimveliso yamayeza, izithambiso okanye ukutya okusekelwe kwizityalo, i-methylcellulose yokwenyani yinto ekhethekileyo ehlala ilapha.
