I-Carboxymethylcellulose (CMC) kunye ne-xanthan gum zombini zii-hydrophilic colloids eziqhele ukusetyenziswa kushishino lokutya njengezinto ezityebisayo, zizinzisi, kunye nee-gelling agents. Nangona babelana ngokufana okusebenzayo, ezi zinto zimbini zahluke kakhulu ngemvelaphi, ukwakheka kunye nokusetyenziswa.
I-Carboxymethylcellulose (CMC):
1. Umthombo kunye nesakhiwo:
Umthombo: I-CMC ithathwe kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zesityalo. Ngokuqhelekileyo ikhutshwe kwi-pulp yokhuni okanye i-cotton fibers.
Ulwakhiwo: I-CMC yi-cellulose derivative eveliswa yi-carboxymethylation yee-molecule ze-cellulose. I-Carboxymethylation ibandakanya ukuqaliswa kwamaqela e-carboxymethyl (-CH2-COOH) kwisakhiwo se-cellulose.
2. Ukunyibilika:
I-CMC iyanyibilika emanzini, yenza isisombululo esicacileyo kunye ne-viscous. Umgangatho wokutshintshwa (DS) kwi-CMC ichaphazela ukunyibilika kwayo kunye nezinye iipropati.
3. Umsebenzi:
Ukujiya: I-CMC isetyenziswa ngokubanzi njenge-arhente yokutyebisa kwiimveliso zokutya ezahlukeneyo, kuquka iisosi, izinxibo kunye neemveliso zobisi.
Ukuzinza: Inceda ukuzinzisa i-emulsions kunye nokumiswa, ukuthintela ukuhlukana kwezithako.
Ukugcinwa kwamanzi: I-CMC yaziwa ngokukwazi kwayo ukugcina amanzi, inceda ukugcina ukufuma ekutyeni.
4. Isicelo:
I-CMC iqhele ukusetyenziswa kwishishini lokutya, amayeza kunye nezithambiso. Kwishishini lokutya, isetyenziswa kwiimveliso ezifana ne-ayisikrimu, iziselo kunye neempahla ezibhakiweyo.
5. Izithintelo:
Nangona i-CMC isetyenziswa ngokubanzi, ukusebenza kwayo kunokuchatshazelwa zizinto ezifana ne-pH kunye nobukho beeyoni ezithile. Ingabonakalisa ukuthotywa kokusebenza phantsi kweemeko ezineasidi.
Xanthan gum:
1. Umthombo kunye nesakhiwo:
Umthombo: I-Xanthan gum yi-microbial polysaccharide eveliswa kukubiliswa kweecarbohydrates yi-bacterium Xanthomonas campestris.
Ulwakhiwo: Isakhiwo esisisiseko se-xanthan gum siquka i-cellulose backbone kunye ne-trisaccharide side chain. Iqulethe iiyunithi ze-glucose, i-mannose kunye ne-glucuronic acid.
2. Ukunyibilika:
I-Xanthan gum inyibilika kakhulu emanzini, yenza isisombululo se-viscous kwiindawo eziphantsi.
3. Umsebenzi:
Ukuqina: Njenge-CMC, i-xanthan gum yiarhente esebenzayo yokuqina. Inika ukutya okugudileyo kunye ne-elastic texture.
Ukuzinza: I-Xanthan gum iqinisa ukumiswa kunye ne-emulsions, ukukhusela ukuhlukana kwesigaba.
I-Gelling: Kwezinye izicelo, i-xanthan gum inceda ekwenzeni ijeli.
4. Isicelo:
I-Xanthan gum inoluhlu olubanzi lokusetyenziswa kwishishini lokutya, ngakumbi kwi-baking-free yokubhaka, isaladi yokunxiba kunye neesosi. Ikwasetyenziswa kwizicelo ezahlukeneyo zoshishino.
5. Izithintelo:
Kwezinye izicelo, ukusetyenziswa ngokugqithiseleyo kwe-xanthan gum kunokubangela ukuncamathela okanye "i-runny". Ukulawulwa ngokucokisekileyo kwedosi kunokufuneka ukuphepha iimpawu ezingathandekiyo zesicatshulwa.
Thelekisa:
1. Umthombo:
I-CMC ithathwe kwi-cellulose, i-polymer esekwe kwisityalo.
Xanthan gum uveliswa ngokusebenzisa microbial fermentation.
2.Ulwakhiwo lweChemical:
I-CMC yi-cellulose ephuma kwi-carboxymethylation.
I-Xanthan gum inesakhiwo esiyinkimbinkimbi kunye ne-trisaccharide side chain.
3. Ukunyibilika:
Zombini i-CMC kunye ne-xanthan gum zinyibilika emanzini.
4. Umsebenzi:
Zombini zisebenza njengezinto ezityebileyo kunye nezizinzisi, kodwa zinokuba neziphumo ezahlukileyo kancinci kukwakheka.
5. Isicelo:
I-CMC kunye ne-xanthan gum zisetyenziswa kwiintlobo ngeentlobo zokutya kunye nezicelo zoshishino, kodwa ukhetho phakathi kwabo lunokuxhomekeka kwiimfuno ezithile zemveliso.
6. Izithintelo:
Nganye inemida yayo, kwaye ukhetho phakathi kwabo lunokuxhomekeka kwizinto ezifana ne-pH, umthamo, kunye nokuthungwa okufunwayo kwemveliso yokugqibela.
Nangona i-CMC kunye ne-xanthan gum zinokusetyenziswa okufanayo njenge-hydrocolloids kwishishini lokutya, ziyahluka ngemvelaphi, isakhiwo kunye nokusetyenziswa. Ukhetho phakathi kwe-CMC kunye ne-xanthan gum kuxhomekeke kwiimfuno ezithile zemveliso, kuthathelwa ingqalelo izinto ezifana ne-pH, i-dosage kunye neempawu ezifunwayo zesicatshulwa. Zombini ezi zinto zinegalelo elikhulu ekuthungeni, ukuzinza kunye nomgangatho jikelele weentlobo ngeentlobo zokutya kunye neemveliso zoshishino.
