UMethylcelupalulose usenokungabi ligama lendlu, kodwa yi-polymer ye-polymer enezicelo ezininzi zezolimo nezomziselo. Iipropathi zayo ezizodwa zenza ukuba zibe yinto efanelekileyo yoluhlu olubanzi lokusetyenziswa, ukusuka kwiisosi zokutyibilika ukuya kwenza i-chirmatings. Kodwa eyona nto ibeka i-methylcelsulose ngaphandle kwezinye izinto kukukwazi ukumelana namaxesha amane.
Ngaphambi kokuba singene kwisayensi emva kweMethylcelup I-methylcelculose luhlobo lwe-selsulose ether ethathwe kwi-seluplose, i-polymer yendalo ifumaneka kwiindonga zeseli zezityalo. I-seluplose yenye yezona zinto zidibeneyo zomhlaba zininzi emhlabeni kwaye zifumaneka kwimithombo emininzi yezityalo, kubandakanya iipulp, umqhaphu kunye ne-bamboo. I-methylcelfulose yenziwa ngokutshintsha imichiza kunye namaqela e-methyl, etshintsha iipropathi zayo kwaye iyenza inyibilike kakhulu emanzini.
Ngoku, masithethe malunga nento eyenza uMthylceluplose owukhethekileyo. Enye yezona ndawo zizodwa ze-methylceluplose kukukwazi ukwenza ijeli xa kuvela amanzi. Lo mgaqo wenzeka ngenxa yokuba amaqela e-methyl kwimolekyuli eselselose yenza umqobo we-hydrophobic epeyinta iimolekyuli zamanzi. Ke xa uMethylcelculose odityanisiwe emanzini, wenza into efana nejeli enokusetyenziselwa izisombululo ze-ticken, iFom Foods, kwaye wenze ii-noodles ezidliwayo.
Kodwa eyona nto ibeka i-methylcelgalose ihlukene nawo kukukwazi ukumelana neziphumo zawo onke amaxesha amane. Oku kungenxa yokuziphatha kwayo okhethekileyo kubushushu obahlukeneyo. Ngamaqondo obushushu asezantsi, njengasebusika, uMethylcelcealupalupose wenza ijeli eyomeleleyo nenobunzima. Oku kubangela ukuba ibe yinto efanelekileyo yokwenza ikhredithi yeendlela zamayeza kunye nezinye iimveliso ekufuneka zikhuselwe umswakama kunye nezinye izinto zokusingqongileyo.
Nangona kunjalo, njengoko iqondo lobushushu liyanda, i-methylcelcelcealsulose iqale ukuthambisa kwaye ichaphazeleke ngakumbi. Kungenxa yokuba njengamaqondo obushushu anyuka, umqobo we-hydrophobic owenziwe ngamaqela e-methyl akasebenzi ekuguqukeni kwiimolekyuli zamanzi. Ngenxa yoko, ubunzima obufana nejeli obuveliswa nguMethylcelgalose bungabi mdaka kwaye buthathaka ngakumbi, zenza kube lula ukubumba kunye nobume.
Ehlotyeni, iMethylcelcealsulose iya kuba yinto entle, iyenza ibe yinto entle yokwenza iimveliso ezidliwayo ezinje nge-gevinarian kunye nenyama yenyama. Ingasetyenziselwa njengearhente yokuthambisa kwiisopho kunye neesuphu kuba zihlala zizinzile nakubushushu obuphezulu.
Esona sibonelelo sibalulekileyo sokwenyani se-methylcelilose yokwenene kukukwazi ukuzinza ngokuhamba kwexesha. Ngokungafaniyo nezinye izinto ezinokuthi zinciphise okanye ziphule ngokuhamba kwexesha, i-methylcelcealsulose ye-methylcelsulose iya kuzigcina iipropathi zayo iminyaka, ezenza ukuba zibe yinto efanelekileyo yokusetyenziswa kwexesha elide. Oku kubaluleke ngakumbi kumashishini anje ngamayeza kunye ne-cosmetics, apho kufuneka bagcine ukusebenza kwabo nokuziqhelanisa nexesha elide.
Elinye imvume ye-methylcelculose yokwenyani kukhuseleko lwayo kwaye luqaliseko. Ihlelwe yi-FDA njengokuchongwa ngokubanzi njengoko ikhuselekile (i-GRAs), oko kuthetha ukuba ithathelwa ingqalelo ukuba ikhuselekile ukusetyenziswa kwaye isebenzise ukutya, iziyobisi kunye ne-cosmetics. Kukwanetyhefu kwaye ingonakalisi, iyenza ukhetho olunobuhlobo olunobuhlobo.
Ukongeza kubuninzi bemizi-mveliso, i-methylcelcelculose isetyenziswa kwintsimi ye-culimary. Ngapha koko, sisithako esithandwayo kwi-vegan ezininzi kunye nezitya zemifuno ngenxa yokukwazi kwayo ukwenza into efana nejeli ngaphandle kokusetyenziswa kweemveliso zezilwanyana. Ihlala isetyenziselwa ukwenza ezinye iindlela zenyama ezisekwe kwizityalo kunye neempahla ezibhakiweyo kunye needessert.
Ukuqukumbela, i-methylcelcelculose yinto ephezulu enezibonelelo ezininzi ngaphezulu kwezinye iipolymers. Amandla ayo okumelana nomaxesha amane, gcina uzinzo ngokuhamba kwexesha, kwaye uhlala ekhuselekile kwaye uguqulelo lwenza ukuba lilungele amashishini amaninzi. Nokuba isetyenziswa kwimveliso yamayeza, i-cosmetics okanye ukutya okusekwe kwizityalo, i-methylcelcelculose yenyani elapha elapha yokuhlala.
