I-Methylcellulose (MC)yikhompawundi ephuma kwiselulosi kwaye isetyenziswa kakhulu kukutya, amayeza, izinto zokuthambisa kunye namanye amashishini. I-derivative ye-cellulose e-soluble yamanzi kunye ne-thickening ethile, i-gelling, i-emulsification, ukumiswa kunye nezinye iimpawu.
Iimpawu zeMichiza kunye neendlela zokuvelisa i-methylcellulose
I-Methylcellulose ifunyenwe ngokuphendula i-cellulose (icandelo eliphambili lesakhiwo kwizityalo) kunye ne-methylating agent (njenge-methyl chloride, i-methanol, njl.). Ngokusebenzisa i-methylation reaction, iqela le-hydroxyl (-OH) ye-cellulose ithathelwa indawo liqela le-methyl (-CH3) ukuvelisa i-methylcellulose. Isakhiwo se-methylcellulose siyafana neselulosi yasekuqaleni, kodwa ngenxa yeenguqu zayo zesakhiwo, inokuchithwa emanzini ukwenza isisombululo se-viscous.
I-solubility, i-viscosity kunye ne-gelling properties ze-methylcellulose zihambelana ngokusondeleyo nezinto ezifana neqondo le-methylation kunye ne-molecular weight. Ngokweemfuno ezahlukeneyo, i-methylcellulose inokwenziwa kwizisombululo ze-viscosities ezahlukeneyo, ngoko inoluhlu olubanzi lwezicelo kumashishini ahlukeneyo.
Ukusetyenziswa okuphambili kwe-methylcellulose
Ishishini lokutya
Kwishishini lokutya, i-methylcellulose isetyenziswa ikakhulu njenge-thickener, stabilizer, emulsifier kunye ne-gelling agent. Ngokomzekelo, kwi-fat-fat or fat-free foods, i-methylcellulose inokulinganisa ukunambitha kwamanqatha kwaye inikeze ukuthungwa okufanayo. Idla ngokusetyenziselwa ukwenza ukutya osele kukulungele ukutyiwa, ukutya okukhenkcezisiweyo, iilekese, iziselo, nezinxibo zesaladi. Ukongeza, i-methylcellulose ikwasetyenziswa rhoqo kwimifuno okanye kwizityalo ezithatha indawo yenyama njengezongezo zokunceda ukuphucula incasa kunye nokuthungwa.
Ukusetyenziswa kwamachiza
Kumashishini amayeza, i-methylcellulose isoloko isetyenziswa njenge-excipient ekwenzeni amachiza, ngokukodwa ii-agent ezikhutshwayo ezilawulwayo zamachiza. Iyakwazi ukukhulula iziyobisi ngokukhawuleza emzimbeni, ngoko ke i-methylcellulose isoloko isetyenziswa njengomthwali kweminye imimiselo yokukhutshwa kwechiza elawulwayo. Ukongeza, i-methylcellulose ikwasetyenziselwa ukulungisa iinyembezi zokwenziwa ukunceda ukunyanga iingxaki zamehlo ezifana namehlo omileyo.
Izithambiso kunye neeMveliso zoNakekelo loMntu
I-Methylcellulose isetyenziswa njenge-thickener, stabilizer, kunye ne-moisturizer kwi-cosmetics, kwaye isoloko isetyenziswa kwiimveliso ezifana ne-lotions, i-creams, kunye ne-shampoo. Inokunyusa i-viscosity kunye nokuzinza kwemveliso, ukwenza imveliso ibe lula xa isetyenziswa.
Usetyenziso lwemizi-mveliso
I-Methylcellulose isetyenziswa ngokubanzi kwizinto zokwakha, ngakumbi kwi-samente, i-coatings, kunye ne-adhesives, njenge-thickener kunye ne-emulsifier. Inokuphucula ukunamathela, ukumanzi, kunye nokusebenza kwemveliso.
Ukhuseleko lwe-methylcellulose
I-Methylcellulose yinto yekhemikhali ebonwa ngokubanzi njengekhuselekile. UMbutho wezeMpilo weHlabathi (i-WHO) kunye ne-US Food and Drug Administration (FDA) zombini ziyithatha njengesongezo esinomngcipheko ophantsi. I-Methylcellulose ayigaywanga emzimbeni kwaye njengefayibha yokutya enyibilikayo emanzini, inokukhutshelwa ngokuthe ngqo ngamathumbu. Ke ngoko, i-methylcellulose inetyhefu ephantsi kwaye akukho bungozi bucacileyo kumzimba womntu.
Iimpembelelo kumzimba womntu
I-Methylcellulose ayisoloko ingena emzimbeni. Inokunceda ukukhuthaza i-peristalsis yamathumbu kwaye incede ukukhulula iingxaki zokuqhina. Njengefiber yokutya, inomsebenzi wokuthambisa kunye nokukhusela amathumbu, kwaye inokulawula amanqanaba eswekile yegazi. Nangona kunjalo, ukuthathwa okukhulu kwe-methylcellulose kunokubangela ukuphazamiseka kwesisu, njenge-flatulence okanye isifo sohudo. Ngoko ke, kubaluleke kakhulu ukusebenzisa umlinganiselo ochanekileyo we-methylcellulose xa uyisebenzisa njengesongezelelo.
Iimpembelelo kwimigaqo-siseko ye-aleji
Nangona i-methylcellulose ngokwayo ayinakho ukuchasana nokungaguquki, abanye abantu abanovelwano banokuba nokusabela okungekuhle kwiimveliso ezine-methylcellulose. Ngokukodwa kwezinye izimonyo, ukuba imveliso iqulethe ezinye izithako ezicasulayo, inokubangela ukungahambi kakuhle kwesikhumba. Ke ngoko, kungcono ukwenza uvavanyo lwasekhaya ngaphambi kokusetyenziswa.
Izifundo malunga nokusetyenziswa kwexesha elide
Okwangoku, izifundo malunga nokuthatha ixesha elide kwe-methylcellulose azifumananga ukuba ziya kubangela iingxaki zempilo ezinzulu. Inani elikhulu lezifundo libonise ukuba i-methylcellulose, xa isetyenziswe njengesongezelelo sefiber yokutya, inefuthe elithile elihle ekuphuculeni ukuqunjelwa kunye nokukhuthaza impilo yamathumbu.
Njengokutya okukhuselekileyo kunye neziyobisi, i-methylcellulose isetyenziswa ngokubanzi kumashishini amaninzi, kuquka ukutya, amayeza, izithambiso, njl. Nangona kunjalo, ukutya kakhulu kunokubangela ukuphazamiseka kwesisu, ngoko kufuneka kusetyenziswe ngokumodareyitha. Ngokubanzi, i-methylcellulose yinto ekhuselekileyo, esebenzayo kwaye esetyenziswa ngokubanzi.
