Ngaba i-carboxymethylcellulose yinto etyebisayo?

I-Carboxymethyl Cellulose (CMC) yikhompawundi ebalulekileyo yepolymer enyibilikayo emanzini esetyenziswa kakhulu ekutyeni, kumayeza, kwimichiza yemihla ngemihla, emalaphu nakwezinye iindawo. Kwishishini lokutya, enye yezona zinto zibalulekileyo zokusetyenziswa kwe-CMC kukutyeba. I-Thickeners yiklasi yezongezo ezandisa i-viscosity yolwelo ngaphandle kokutshintsha ngokuphawulekayo ezinye iimpawu zolwelo.

1. Ubume bekhemikhali kunye nomgaqo wokuqina we-carboxymethyl cellulose
I-Carboxymethylcellulose yi-derivative ye-cellulose eyenziwe ngokutshintsha inxalenye yamaqela e-hydroxyl (-OH) ye-cellulose kunye namaqela e-carboxymethyl (-CH2COOH). Iyunithi yayo yolwakhiwo esisiseko yityathanga eliphinda-phindayo le-β-D-glucose. Ukuqaliswa kwamaqela e-carboxymethyl kunika i-CMC i-hydrophilicity, inika ukunyibilika okulungileyo kunye nokukwazi ukujiya emanzini. Umgaqo wayo wokuqina usekelwe ikakhulu kula manqaku alandelayo:

Isiphumo sokudumba: I-CMC iya kudumba emva kokufunxa iimolekyuli zamanzi emanzini, zenze isakhiwo sothungelwano, ukuze iimolekyuli zamanzi zibanjwe kwisakhiwo sayo, zikhulise i-viscosity yenkqubo.

Isiphumo sentlawulo: Amaqela e-carboxyl kwi-CMC aya kuthi afakwe i-ioni emanzini ukuze enze iintlawulo ezingalunganga. La maqela ahlawulisiweyo aya kwenza i-electrostatic repulsion emanzini, ebangela ukuba amakhonkco e-molecular avuleke kwaye enze isisombululo kunye ne-viscosity ephezulu.

Ubude bekhonkco kunye noxinzelelo: Ubude betsheyini kunye noxinzelelo lwesisombululo seemolekyuli zeCMC ziya kuchaphazela isiphumo saso sokuqina. Ngokuqhelekileyo, ukuphakama kwe-molecular weight, i-viscosity enkulu yesisombululo; ngelo xesha, ukuphakama koxinzelelo lwesisombululo, i-viscosity yenkqubo nayo iyanda.

I-molecular cross-linking: Xa i-CMC ichithwa emanzini, ngenxa yokudibanisa phakathi kweeamolekyu kunye nokwakhiwa kwesakhiwo sothungelwano, iimolekyuli zamanzi zithintelwe kwiindawo ezithile, okubangelwa ukuhla kwe-fluidity yesisombululo. isiphumo sokuqina.

2. Ukusetyenziswa kwe-carboxymethyl cellulose kwishishini lokutya
Kwishishini lokutya, i-carboxymethylcellulose isetyenziswa ngokubanzi njenge-thickener. Ezi zilandelayo zezinye iimeko zesicelo eziqhelekileyo:

Iziselo kunye neemveliso zobisi: Kwiijusi zeziqhamo kunye neziselo ze-lactobacillus, i-CMC inokunyusa i-viscosity yesiselo, iphucule incasa kwaye yandise ubomi beshelufu. Ngokukodwa kwiimveliso zobisi ezinamafutha aphantsi kunye ne-fat-free, i-CMC inokutshintsha inxalenye yamafutha obisi kunye nokuphucula ukuthungwa kunye nokuzinza kwemveliso.

I-Sauces kunye ne-condiments: Kwi-salad dressing, i-tomato sauce kunye ne-soy sauce, i-CMC isebenza njenge-thickener kunye ne-arhente yokuxhoma ukuphucula ukufana kwemveliso, ukuphepha ukubola, kunye nokwenza imveliso izinze ngakumbi.

I-ayisikrimu kunye neziselo ezibandayo: Ukongeza i-CMC kwi-ayisikrimu kunye neziselo ezibandayo kunokuphucula ukwakheka kwemveliso, kuyenze ibe denser kunye ne-elastic ngakumbi, ukuthintela ukubunjwa kweekristale ze-ice kunye nokuphucula incasa.

Isonka kunye neemveliso ezibhakiweyo: Kwiimveliso ezibhakiweyo ezifana nesonka kunye namaqebengwana, i-CMC isetyenziswa njengomphuculi wentlama ukunyusa ukwanda kwentlama, ukwenza isonka sibe thambile, kunye nokwandisa ubomi beshelufu.

3. Ezinye izicelo ezityebisayo ze-carboxymethyl cellulose
Ukongeza kokutya, i-carboxymethylcellulose idla ngokusetyenziswa njenge-thickener kumayeza, izimonyo, iikhemikhali zemihla ngemihla kunye namanye amashishini. Umzekelo:

Umzi-mveliso wamachiza: Kumayeza, i-CMC isoloko isetyenziselwa ukujiya iisyrups, iicapsules, kunye neepilisi, ukuze amayeza abe neziphumo ezingcono zokubumba kunye nokuqhekeka, kwaye anokuphucula uzinzo lwamayeza.

Izithambiso kunye neekhemikhali zemihla ngemihla: Kwiikhemikhali zemihla ngemihla ezifana ne-toothpaste, i-shampoo, i-gel yokugeza, njl., i-CMC inokunyusa ukuhambelana kwemveliso, ukuphucula amava okusebenzisa, kwaye yenza i-paste iyunifomu kwaye izinzile.

4. Ukhuseleko lwe-carboxymethyl cellulose
Ukhuseleko lwe-carboxymethylcellulose luqinisekisiwe ngezifundo ezininzi. Ekubeni i-CMC ivela kwi-cellulose yendalo kwaye ayigaywanga kwaye ifakwe emzimbeni, ngokuqhelekileyo ayinayo impembelelo embi kwimpilo yabantu. Bobabini uMbutho wezeMpilo weHlabathi (i-WHO) kunye neKomiti yeeNgcali eziDityanisiweyo kwiZongezo zokutya (JECFA) zihlela njengezongezo zokutya ezikhuselekileyo. Ngedosi efanelekileyo, i-CMC ayivelisi zimpendulo eziyityhefu kwaye inefuthe elithile lokuthambisa kunye ne-laxative kumathumbu. Nangona kunjalo, ukutya kakhulu kunokubangela ukuphazamiseka kwesisu, ngoko ke imigangatho yedosi emiselweyo kufuneka ithotyelwe ngokungqongqo kwimveliso yokutya.

5. Izinto eziluncedo kunye nokungonakali kwe-carboxymethylcellulose
I-Carboxymethylcellulose ineengenelo kunye nemida yayo njenge-thickener:

Izinto eziluncedo: I-CMC inonyibiliko olulungileyo lwamanzi, uzinzo lwe-thermal kunye nokuzinza kweekhemikhali, i-asidi kunye ne-alkali ukumelana, kwaye ayithotywanga ngokulula. Oku kuvumela ukuba isetyenziswe kwiindawo ezahlukeneyo zokucwangcisa.

Izinto ezingeloncedo: I-CMC inokuba yi-viscous kakhulu kwiindawo eziphezulu kwaye ayifanelekanga zonke iimveliso. I-CMC iya kuthomalalisa kwindawo eneasidi, nto leyo ekhokelela ekuncipheni kwesiphumo sayo sokuqina. Kufuneka ulumke xa uyisebenzisa kwiziselo ezimuncu okanye ekutyeni.

Njenge-thickener ebalulekileyo, i-carboxymethylcellulose isetyenziswa ngokubanzi kukutya, amayeza, izithambiso kunye nezinye iindawo ngenxa yokunyibilika kakuhle kwamanzi, ukuqina kunye nokuzinza. Impembelelo yayo ephezulu yokuqina kunye nokhuseleko yenza ukuba ibe yinto esetyenziswa ngokuqhelekileyo kwishishini lanamhlanje. Nangona kunjalo, ukusetyenziswa kwe-CMC kufuneka kulawulwe ngokwesayensi ngokweemfuno ezithile kunye nemigangatho yedosi ukuqinisekisa ukuphuculwa kokusebenza kwayo kunye nokhuseleko lokutya.
