Ukusetyenziswa kwe-sodium carboxymethyl cellulose kunye ne-hydroxyethyl cellulose kwiimveliso zemichiza yemihla ngemihla

I-Carboxymethylcellulose sodium (CMC-Na) yinto ephilayo, i-carboxymethylated derivative ye-cellulose, kunye neyona nto ibalulekileyo ye-ionic cellulose gum.I-sodium carboxymethyl cellulose idla ngokuba yi-anionic polymer compound elungiselelwe ngokusabela i-cellulose yendalo kunye ne-alkali ye-caustic kunye ne-monochloroacetic acid, enobunzima bemolekyuli ukusuka kumawaka amaninzi ukuya kwizigidi.I-CMC-Na yi-fibrous emhlophe okanye i-granular powder, ayinavumba, ingenancasa, i-hygroscopic, ilula ukusasazeka emanzini ukwenza isisombululo se-colloidal esicacileyo.

Xa ingathathi hlangothi okanye i-alkaline, isisombululo singulwelo oluphezulu lwe-viscosity.Izinzile kumayeza, ukukhanya kunye nobushushu.Nangona kunjalo, ubushushu bukhawulelwe kwi-80°C, kwaye ukuba ishushu ixesha elide ngaphezu kwama-80°C, i-viscosity iya kuncipha kwaye ayiyi kunyibilika emanzini.

I-sodium carboxymethyl cellulose ikwaluhlobo lwe-thickener.Ngenxa yeempawu zayo ezilungileyo zokusebenza, isetyenziswe ngokubanzi kwishishini lokutya, kwaye ikwakhuthaze uphuhliso olukhawulezayo nolunempilo lweshishini lokutya ukuya kuthi ga kwinqanaba elithile.Ngokomzekelo, ngenxa yokuqina kwayo kunye ne-emulsifying effect, ingasetyenziselwa ukuzinzisa iziselo ze-yogurt kunye nokwandisa i-viscosity ye-yoghurt system;ngenxa yezinto ezithile ze-hydrophilicity kunye ne-rehydration, ingasetyenziselwa ukuphucula ukusetyenziswa kwe-pasta njengesonka kunye nesonka esiqhumayo.umgangatho, ukwandisa ubomi beshelufu yeemveliso zepasta kunye nokuphucula ukunambitha.

Ngenxa yokuba inefuthe elithile le-gel, kunenzuzo ekutyeni ukwenza i-gel engcono, ngoko ingasetyenziselwa ukwenza i-jelly kunye ne-jam;Isenokusetyenziswa njengezinto ezityiwayo zokugquma, ezidityaniswe nezinye izityebe, kwaye zisasazwe Kwindawo ethile yokutya, inokugcina ukutya kutsha ngowona mgangatho mkhulu, kwaye ngenxa yokuba zizinto ezityiwayo, aziyi kubangela iziphumo ezibi ebantwini. impilo.Ke ngoko, i-CMC-Na yebakala lokutya, njengesongezo sokutya esifanelekileyo, isetyenziswa kakhulu kwimveliso yokutya kwishishini lokutya.

IHydroxyethylcellulose (HEC), ifomula yemichiza (C2H6O2)n, imhlophe okanye iluhlaza tyheli, ayinavumba, ingenatyhefu okanye ilumgubo oluqinileyo, oluqulunqwe yialkaline cellulose kunye ne-ethylene oxide (okanye i-chlorohydrin) Ilungiselelwe ukusabela kwe-etherification, yeye-non- ionic cellulose ethers enyibilikayo.Ngenxa yokuba i-HEC ineempawu ezintle zokuqina, ukumisa, ukusabalalisa, i-emulsifying, ukubopha, ukwenza ifilimu, ukukhusela umswakama kunye nokubonelela nge-colloid yokukhusela.

Inyibilika ngokulula emanzini kwi-20°C. Ukunganyibiliki kwizinyibilikisi eziqhelekileyo eziphilayo.Inemisebenzi yokuqina, ukuxhoma, ukubopha, ukumilisela, ukusabalalisa, kunye nokugcina ukufuma.Izisombululo kwiindidi ezahlukeneyo ze-viscosity zinokulungiswa.Inonyibiliko olulungileyo lwetyuwa kwi-electrolytes.

I-viscosity itshintsha kancinci kuluhlu lwexabiso le-PH 2-12, kodwa i-viscosity iyancipha ngaphaya kolu luhlu.Ineempawu zokuqina, ukumisa, ukubopha, i-emulsifying, ukusabalalisa, ukugcina umswakama kunye nokukhusela i-colloid.Izisombululo kwiindidi ezahlukeneyo ze-viscosity zinokulungiswa.
