I-sodium carboxymethyl cellulose ekutyeni

Intshayelelo

I-sodium carboxymethyl cellulose (CMC) sisongezo sokutya esisetyenziswa ngokubanzi esisetyenziselwa ukuphucula ukuthungwa, ukuzinza, kunye nobomi beshelufu yeemveliso zokutya ezahlukeneyo. I-CMC ngumgubo omhlophe, ongenavumba, ongenancasa ophuma kwiselulosi, eyona nxalenye iphambili yeendonga zeeseli zesityalo. I-polysaccharide, oku kuthetha ukuba yenziwe ngamamolekyuli amaninzi eswekile adityaniswe kunye. I-CMC isetyenziswa kwiimveliso ezahlukeneyo zokutya, kubandakanya i-ayisikrimu, iisosi, izinxibo, kunye neempahla ezibhakiweyo.

Imbali

I-CMC yaphuhliswa okokuqala kwiminyaka yoo-1900 ngusokhemisti waseJamani, uGqr. Karl Schardinger. Wafumanisa ukuba ngokunyanga i<em>cellulose ngendibaniselwano ye<em>sodium hydroxide ne<em>monochloroacetic acid, unokudala ikhompawundi entsha enyibilika ngakumbi emanzini kune<em>cellulose. Le khompawundi intsha yabizwa ngokuba yicarboxymethyl cellulose, okanye iCMC.

Ngeminyaka yoo-1950, i-CMC yaqala ukusetyenziswa njengesongezo sokutya. Yayisetyenziselwa ukujiya kunye nokuzinzisa iisosi, izinxibo kunye nezinye iimveliso zokutya. Ukusukela ngoko, i-CMC iye yaba sisongezo sokutya esithandwayo ngenxa yokukwazi ukuphucula ukuthungwa, ukuzinza, kunye nobomi beshelufu yeemveliso zokutya.

IKhemistri

I-CMC yi-polysaccharide, nto leyo ethetha ukuba yenziwe ngeemolekyuli ezininzi zeswekile ezidityaniswe kunye. Inxalenye ephambili ye-CMC yi-cellulose, eyitsheyini elide leemolekyuli zeglucose. Xa i-cellulose iphathwa ngendibaniselwano ye-sodium hydroxide kunye ne-monochloroacetic acid, yenza i-carboxymethyl cellulose. Le nkqubo yaziwa ngokuba yi-carboxymethylation.

I-CMC ngumgubo omhlophe, ongenavumba, ongenancasa onyibilikayo kuwo omabini amanzi abandayo nashushu. Yinto engeyiyo ityhefu, i-non-allergenic, kunye ne-non-arritation into ekhuselekileyo ekusetyenzisweni komntu.

Umsebenzi

I-CMC isetyenziswa kwiimveliso ezahlukeneyo zokutya ukuphucula ukuthungwa kwazo, ukuzinza, kunye nobomi beshelufu. Isetyenziswa njenge-ejenti yokujiya ukunika iimveliso zokutya ukuthungwa okukhrimu nokuzinzisa ukuze zingahlukani okanye zonakaliswe. I-CMC ikwasetyenziswa njenge-emulsifier yokunceda ioli kunye namanzi ukuxuba kunye.

Ukongeza, i-CMC isetyenziselwa ukuthintela ukwakheka kwekristale yomkhenkce kwiidessert ezikhenkcezisiweyo, ezinje nge-ayisikrimu. Ikwasetyenziselwa ukuphucula ukuthungwa kwezinto ezibhakiweyo, ezinje ngeekeyiki kunye namaqebengwana.

Ummiselo

I-CMC ilawulwa yi-Food and Drug Administration (FDA) eMelika. I-FDA ibeke inqanaba eliphezulu lokusetyenziswa kwe-CMC kwiimveliso zokutya. Umgangatho ophezulu wokusetyenziswa ngu-0.5% ngobunzima.

Ukuqukumbela

I-sodium carboxymethyl cellulose (CMC) sisongezo sokutya esisetyenziswa ngokubanzi esisetyenziselwa ukuphucula ukuthungwa, ukuzinza, kunye nobomi beshelufu yeemveliso zokutya ezahlukeneyo. I-CMC ngumgubo omhlophe, ongenavumba, ongenancasa ophuma kwiselulosi, eyona nxalenye iphambili yeendonga zeeseli zesityalo. I-polysaccharide, oku kuthetha ukuba yenziwe ngamamolekyuli amaninzi eswekile adityaniswe kunye. I-CMC isetyenziswa njenge-arhente etyebisayo, i-emulsifier, kunye nokuthintela ukwakheka kwekristale yomkhenkce kwiidessert ezikhenkcezisiweyo. Ilawulwa yi-FDA e-United States, kunye nenqanaba eliphezulu lokusetyenziswa kwe-0.5% ngesisindo.
