I-Carboxymethylcellulose (CMC) ne-xanthan gum womabili ama-hydrophilic colloid avame ukusetshenziswa embonini yokudla njengama-thickeners, stabilizers, nama-gelling agents.Nakuba zabelana ngokufana kokusebenza, lezi zinto zombili zihluke kakhulu ngemvelaphi, ukwakheka, kanye nokusebenza.
I-Carboxymethylcellulose (CMC):
1. Umthombo nesakhiwo:
Umthombo: I-CMC isuselwa ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo.Ngokuvamile ikhishwa ku-pulp yokhuni noma emicu yekotini.
Isakhiwo: I-CMC iphuma ku-cellulose ekhiqizwa i-carboxymethylation yama-molecule e-cellulose.I-Carboxymethylation ihilela ukwethulwa kwamaqembu e-carboxymethyl (-CH2-COOH) esakhiweni se-cellulose.
2. Ukunyibilika:
I-CMC iyancibilika emanzini, yakha isixazululo esicacile nesibonakalayo.Izinga lokushintsha (DS) ku-CMC lithinta ukunyibilika kwayo nezinye izici.
3. Umsebenzi:
Ukuqina: I-CMC isetshenziswa kabanzi njenge-ejenti yokuqina emikhiqizweni ehlukahlukene yokudla, okuhlanganisa amasoso, okokugqoka kanye nemikhiqizo yobisi.
Ukuzinza: Kuyasiza ukuzinzisa ama-emulsions nokumiswa, ukuvimbela ukuhlukaniswa kwezithako.
Ukugcinwa Kwamanzi: I-CMC yaziwa ngamandla ayo okugcina amanzi, isiza ukugcina umswakama ekudleni.
4. Isicelo:
I-CMC ivame ukusetshenziswa embonini yokudla, kwezemithi nezimonyo.Embonini yokudla, isetshenziswa emikhiqizweni efana no-ayisikhilimu, iziphuzo kanye nezimpahla ezibhakwayo.
5. Imikhawulo:
Nakuba i-CMC isetshenziswa kakhulu, ukusebenza kwayo kungaphazanyiswa izici ezifana ne-pH kanye nokuba khona kwama-ion athile.Ingase ibonise ukuwohloka kokusebenza ngaphansi kwezimo ezine-acidic.
I-Xanthan gum:
1. Umthombo nesakhiwo:
Umthombo: I-Xanthan gum iyi-polysaccharide encane ekhiqizwa ukuvutshelwa kwama-carbohydrate yi-bacterium i-Xanthomonas campestris.
Isakhiwo: Isakhiwo esiyisisekelo se-xanthan gum siqukethe umgogodla we-cellulose onamaketanga aseceleni e-trisaccharide.Iqukethe amayunithi e-glucose, mannose kanye ne-glucuronic acid.
2. Ukunyibilika:
I-Xanthan gum incibilika kakhulu emanzini, yenza isixazululo se-viscous ezindaweni eziphansi.
3. Umsebenzi:
Ukuqina: Njenge-CMC, i-xanthan gum iyi-ejenti yokuqina esebenzayo.Inikeza ukudla ukuthungwa okubushelelezi nokunwebeka.
Ukuzinza: I-Xanthan gum iqinisa ukumiswa kanye nama-emulsions, ivimbela ukuhlukaniswa kwesigaba.
I-Gelling: Kwezinye izinhlelo zokusebenza, i-xanthan gum isiza ekwakhekeni kwejeli.
4. Isicelo:
I-Xanthan gum inokusetshenziswa okubanzi embonini yokudla, ikakhulukazi ekubhakeni okungenalo i-gluten, okokugqoka kwamasaladi namasoso.Isetshenziswa futhi ezinhlelweni ezahlukahlukene zezimboni.
5. Imikhawulo:
Kwezinye izinhlelo zokusebenza, ukusetshenziswa ngokweqile kwe-xanthan gum kungabangela ukuthungwa okunamathelayo noma "okugijima".Ukulawulwa ngokucophelela komthamo kungase kudingeke ukuze kugwenywe izici zombhalo ezingathandeki.
Qhathanisa:
1. Umthombo:
I-CMC isuselwa ku-cellulose, i-polymer esekwe esitshalweni.
I-Xanthan gum ikhiqizwa nge-microbial fermentation.
2.Isakhiwo samakhemikhali:
I-CMC iwumphumela we-cellulose okhiqizwa yi-carboxymethylation.
I-Xanthan gum inesakhiwo esiyinkimbinkimbi kakhulu esinamaketanga aseceleni e-trisaccharide.
3. Ukunyibilika:
Kokubili i-CMC ne-xanthan gum ziyancibilika emanzini.
4. Umsebenzi:
Kokubili kusebenza njengeziqinisi neziqinisi, kodwa kungase kube nemiphumela ehluke kancane ekuthungeni.
5. Isicelo:
I-CMC ne-xanthan gum zisetshenziswa ezinhlobonhlobo zokudla nezimboni, kodwa ukukhetha phakathi kwazo kungancika ezidingweni ezithile zomkhiqizo.
6. Imikhawulo:
Ngayinye inemikhawulo yayo, futhi ukukhetha phakathi kwayo kungase kuncike ezicini ezifana ne-pH, umthamo, nokuthungwa okufiswayo komkhiqizo wokugcina.
Nakuba i-CMC ne-xanthan gum zinokusetshenziswa okufanayo njengama-hydrocolloid embonini yokudla, ziyahlukahluka ngemvelaphi, ukwakheka, kanye nokusebenza.Ukukhetha phakathi kwe-CMC ne-xanthan gum kuncike ezidingweni ezithile zomkhiqizo, kucatshangelwa izici ezifana ne-pH, umthamo kanye nezakhiwo ezifiselekayo zombhalo.Zombili izinto zifaka isandla kakhulu ekuthungeni, ukuzinza kanye nekhwalithi iyonke yezinhlobonhlobo zokudla nemikhiqizo yezimboni.
