I-Carboxymethyl Cellulose (CMC) yinxalenye ebalulekileyo yepolymer enyibilikayo emanzini esetyenziswa kakhulu ekutyeni, kumayeza, kwiikhemikhali zemihla ngemihla, kwimpahla kunye nakwezinye iindawo. Kwishishini lokutya, enye yezona ndlela zibalulekileyo zokusetyenziswa kwe-CMC kukwenza i-thickener. I-Thickeners luhlobo lwezongezo ezonyusa i-viscosity yolwelo ngaphandle kokutshintsha kakhulu ezinye iimpawu zolwelo.
1. Ulwakhiwo lweekhemikhali kunye nomgaqo wokuqina kwe-carboxymethyl cellulose
I-Carboxymethylcellulose yi-derivative ye-cellulose eyenziwe ngokutshintsha inxalenye yamaqela e-hydroxyl (-OH) e-cellulose ngamaqela e-carboxymethyl (-CH2COOH). Iyunithi yayo esisiseko yolwakhiwo luchungechunge oluphindaphindayo lwe-β-D-glucose. Ukungeniswa kwamaqela e-carboxymethyl kunika i-CMC hydrophilicity, inika ukunyibilika okuhle kunye nokukwazi ukutyeba emanzini. Umgaqo wayo wokutyeba usekelwe kakhulu kula manqaku alandelayo:
Isiphumo sokudumba: I-CMC iya kudumba emva kokufunxa iimolekyuli zamanzi emanzini, yenze isakhiwo senethiwekhi, ukuze iimolekyuli zamanzi zibanjwe kwisakhiwo sayo, nto leyo eyandisa i-viscosity yenkqubo.
Isiphumo sokutshaja: Amaqela e-carboxyl kwi-CMC aya kufakelwa i-ion kancinci emanzini ukuze avelise ii-charges ezingezizo. La maqela atshajayo aya kwenza i-electrostatic repulsion emanzini, nto leyo ebangela ukuba ii-molecular chains zivuleke kwaye zenze isisombululo esine-viscosity ephezulu.
Ubude betsheyini kunye noxinzelelo: Ubude betsheyini kunye noxinzelelo lwesisombululo seemolekyuli ze-CMC ziya kuchaphazela isiphumo sayo sokutyeba. Ngokubanzi, okukhona ubunzima bemolekyuli buphezulu, kokukhona i-viscosity yesisombululo iba nkulu; kwangaxeshanye, okukhona i-viscosity yesisombululo iphezulu, i-viscosity yenkqubo nayo iyanda.
Ukudibanisa iimolekyuli: Xa i-CMC inyibilika emanzini, ngenxa yokudibanisa iimolekyuli kunye nokwakheka kwesakhiwo senethiwekhi, iimolekyuli zamanzi zithintelwa kwiindawo ezithile, nto leyo ebangela ukwehla kokunyibilika kwesisombululo, ngaloo ndlela ibonisa isiphumo sokutyeba.
2. Ukusetyenziswa kwe-carboxymethyl cellulose kwishishini lokutya
Kwishishini lokutya, i-carboxymethylcellulose isetyenziswa kakhulu njengesithambisi. Nazi ezinye zeemeko eziqhelekileyo zokusetyenziswa:
Iziselo kunye neemveliso zobisi: Kwiijusi zeziqhamo kunye neziselo ze-lactobacillus, i-CMC inokunyusa ubungqindilili besiselo, iphucule incasa kwaye yandise ixesha lokuphelelwa. Ingakumbi kwiimveliso zobisi ezingenamafutha aphantsi kunye nezingenamafutha, i-CMC inokutshintsha inxalenye yamafutha obisi kwaye iphucule ubunjani kunye nokuzinza kwemveliso.
Iisosi kunye neziqholo: Kwisaladi yokubhaka, isosi yetumato kunye nesosi yesoya, i-CMC isebenza njengesithambisi kunye ne-atomizer yokuqinisa ukuze kuphuculwe ukufana kwemveliso, kuthintelwe ukuqhekeka, kwaye kwenze imveliso ihlale izinzile.
I-ayisikhrim kunye neziselo ezibandayo: Ukongeza i-CMC kwi-ayisikhrim kunye neziselo ezibandayo kunokuphucula ulwakhiwo lwemveliso, kuyenze ibe lukhuni kwaye ithambe ngakumbi, kuthintele ukwakheka kweekristale zeqhwa kwaye kuphucule incasa.
Isonka kunye neemveliso ezibhakiweyo: Kwiimveliso ezibhakiweyo ezifana nesonka kunye neekeyiki, i-CMC isetyenziswa njengento ephucula intlama ukuze iphucule ulwandiso lwentlama, yenze isonka sibe thambileyo, kwaye yandise ixesha lokugcinwa kwayo.
3. Ezinye iindlela zokwandisa i-carboxymethyl cellulose
Ukongeza ekutyeni, i-carboxymethylcellulose idla ngokusetyenziswa njengesithambisi kwiimveliso zamayeza, izinto zokuthambisa, iikhemikhali zemihla ngemihla nakwamanye amashishini. Umzekelo:
Ishishini lamayeza: Kumayeza, i-CMC idla ngokusetyenziswa ukwenza isiraphu, iikhaphu, kunye neepilisi zibe nkulu, ukuze amayeza abe nemiphumo engcono yokubumba nokuqhekeka, kwaye aphucule uzinzo lwamayeza.
Izinto zokuthambisa kunye neekhemikhali zemihla ngemihla: Kwiikhemikhali zemihla ngemihla ezifana ne-toothpaste, i-shampoo, i-shower gel, njl.njl., i-CMC inokunyusa ukuhambelana kwemveliso, iphucule amava okusetyenziswa, kwaye yenze i-paste ifane kwaye ihlale izinzile.
4. Ukhuseleko lwe-carboxymethyl cellulose
Ukhuseleko lwe-carboxymethylcellulose luqinisekiswe zizifundo ezininzi. Ekubeni i-CMC isuka kwi-cellulose yendalo kwaye ayigaywa kwaye ayifunxwa emzimbeni, idla ngokuba ayinampembelelo imbi kwimpilo yabantu. I-World Health Organisation (WHO) kunye ne-Joint Expert Committee on Food Additives (JECFA) bayibeka njengesongezo sokutya esikhuselekileyo. Kwidosi efanelekileyo, i-CMC ayivelisi miphumo inobungozi kwaye inefuthe elithile lokuthambisa kunye nokukhupha isisu emathunjini. Nangona kunjalo, ukutya kakhulu kunokubangela ukungakhululeki kwesisu, ngoko ke imigangatho yedosi emiselweyo kufuneka ilandelwe ngokungqongqo kwimveliso yokutya.
5. Iingenelo kunye nokungalungi kwe-carboxymethylcellulose
I-Carboxymethylcellulose ineenzuzo kunye nemida yayo njenge-thickener:
Iingenelo: I-CMC inokunyibilika kakuhle kwamanzi, izinzile kubushushu kwaye izinzile kwiikhemikhali, ayimelani ne-asidi kunye ne-alkali, kwaye ayiboli lula. Oku kuvumela ukuba isetyenziswe kwiindawo ezahlukeneyo zokucubungula.
Iingxaki: I-CMC isenokuba krakra kakhulu xa ikwizinga eliphezulu kwaye ayifanelekanga kuzo zonke iimveliso. I-CMC iya konakala kwindawo ene-asidi, nto leyo ebangela ukuncipha kwesiphumo sayo sokutyeba. Kufuneka ilumke xa uyisebenzisa kwiziselo okanye ekutyeni okune-asidi.
Njengesithambisi esibalulekileyo, i-carboxymethylcellulose isetyenziswa kakhulu ekutyeni, kumayeza, kwizinto zokuthambisa nakwezinye iindawo ngenxa yokunyibilika kwayo kakuhle emanzini, ukuqina kwayo kunye nozinzo. Isiphumo sayo sokuqina kunye nokhuseleko senza ukuba ibe sisongezelelo esisetyenziswa kakhulu kushishino lwanamhlanje. Nangona kunjalo, ukusetyenziswa kwe-CMC kufuneka kulawulwe ngokwesayensi ngokweemfuno ezithile kunye nemigangatho yomthamo ukuqinisekisa ukwenziwa ngcono kokusebenza kwayo kunye nokhuseleko lokutya.
