I-sodium carboxymethyl cellulose ekudleni

Isingeniso

I-sodium carboxymethyl cellulose (CMC) iyisengezo sokudla esisetshenziswa kabanzi esisetshenziselwa ukuthuthukisa ukuthungwa, ukuzinza, nempilo yeshalofu yemikhiqizo yokudla ehlukahlukene. I-CMC iyimpushana emhlophe, engenaphunga, enganambitheki etholakala ku-cellulose, ingxenye eyinhloko yezindonga zamaseli ezitshalo. I-polysaccharide, okusho ukuthi yakhiwe ngama-molecule amaningi kashukela ahlanganiswe ndawonye. I-CMC isetshenziswa emikhiqizweni eyahlukene yokudla, okuhlanganisa u-ayisikhilimu, amasoso, okokugqoka, nezinto ezibhakwayo.

Umlando

I-CMC yasungulwa okokuqala ekuqaleni kwawo-1900 ngusokhemisi waseJalimane, uDkt. Karl Schardinger. Wathola ukuthi ngokwelapha i-cellulose ngenhlanganisela ye-sodium hydroxide ne-monochloroacetic acid, wayengakha inhlanganisela entsha eyayincibilika kakhulu emanzini kune-cellulose. Le nhlanganisela entsha yaqanjwa ngokuthi i-carboxymethyl cellulose, noma i-CMC.

Ngawo-1950, i-CMC yaqala ukusetshenziswa njengesengezo sokudla. Yayisetshenziselwa ukujiyisa nokusimamisa amasoso, okokugqoka, neminye imikhiqizo yokudla. Kusukela lapho, i-CMC isiphenduke isithasiselo sokudla esidumile ngenxa yekhono layo lokuthuthukisa ukuthungwa, ukuzinza, nempilo yeshelufu yemikhiqizo yokudla.

I-Chemistry

I-CMC iyi-polysaccharide, okusho ukuthi yakhiwe ama-molecule amaningi kashukela axhunywe ndawonye. Ingxenye eyinhloko ye-CMC i-cellulose, okuwuchungechunge olude lwama-molecule e-glucose. Uma i-cellulose iphathwa ngenhlanganisela ye-sodium hydroxide ne-monochloroacetic acid, yenza i-carboxymethyl cellulose. Le nqubo yaziwa ngokuthi i-carboxymethylation.

I-CMC iyimpushana emhlophe, engenaphunga, enganambitheki encibilika emanzini abandayo nashisayo. Kuyinto engenabuthi, engeyona i-allergenic, futhi engacasuli futhi ephephile ukuthi isetshenziswe abantu.

Umsebenzi

I-CMC isetshenziswa emikhiqizweni eyahlukene yokudla ukuthuthukisa ukuthungwa kwayo, ukuzinza, kanye nempilo yeshelufu. Isetshenziswa njenge-ejenti yokujiya ukunikeza imikhiqizo yokudla ukuthungwa okunokhilimu kanye nokuzinzisa ukuze ingahlukani noma yonakale. I-CMC iphinde isetshenziswe njenge-emulsifier ukusiza uwoyela namanzi kuxube ndawonye.

Ngaphezu kwalokho, i-CMC isetshenziselwa ukuvimbela ukwakheka kwekristalu yeqhwa kuma-dessert aqandisiwe, njengo-ayisikhilimu. Ibuye isetshenziselwe ukuthuthukisa ukuthungwa kwezinto ezibhakwayo, njengamakhekhe namakhukhi.

Umthethonqubo

I-CMC ilawulwa yi-Food and Drug Administration (FDA) e-United States. I-FDA ibeke izinga eliphezulu lokusetshenziswa kwe-CMC emikhiqizweni yokudla. Izinga eliphezulu lokusetshenziswa ngu-0.5% ngesisindo.

Isiphetho

I-sodium carboxymethyl cellulose (CMC) iyisengezo sokudla esisetshenziswa kabanzi esisetshenziselwa ukuthuthukisa ukuthungwa, ukuzinza, nempilo yeshalofu yemikhiqizo yokudla ehlukahlukene. I-CMC iyimpushana emhlophe, engenaphunga, enganambitheki etholakala ku-cellulose, ingxenye eyinhloko yezindonga zamaseli ezitshalo. I-polysaccharide, okusho ukuthi yakhiwe ngama-molecule amaningi kashukela ahlanganiswe ndawonye. I-CMC isetshenziswa njenge-ejenti yokuqina, i-emulsifier, kanye nokuvimbela ukwakheka kwekristalu yeqhwa kuma-dessert afriziwe. Ilawulwa yi-FDA e-United States, ngezinga eliphezulu lokusetshenziswa kwe-0.5% ngesisindo.
