I-Sodium Carboxymethyl Cellulose (CMC)yi-cellulose yendalo eguqulwe ngokweekhemikhali, esetyenziswa kakhulu kumashishini okutya, amayeza kunye neekhemikhali zemihla ngemihla. I-CMC yodidi lokutya, njengohlobo lwe-polymer colloid, idlala indima yokutyeba, ukuzinzisa, ukugcinwa kwamanzi, i-emulsification kunye nokwenziwa kwefilimu kushishino lokutya. Ngenxa yokhuseleko lwayo oluhle kunye neempawu zayo zokusebenza ezibalaseleyo, i-CMC ibe yenye yezona zinto zivuthiweyo ze-polysaccharide ezisetyenziswa kwizongezo zokutya.
1. Uhlalutyo lokhuseleko lwe-CMC yokutya
I-CMC yodidi lokutya yenziwe nge-cellulose yezityalo zendalo njengezinto eziluhlaza kwaye ivelisa iimveliso ze-carboxymethylated ngokusebenzisa ii-etherification reactions. Ulwakhiwo lwayo luzinzile kwaye alufunxwa kwaye lugaywe lula ngumzimba womntu, ngaloo ndlela lukhuselekile kakhulu kwimpilo. Zombini i-World Health Organization (WHO) kunye ne-Food and Agriculture Organisation yeZizwe eziManyeneyo (FAO) zifake i-CMC kuluhlu "lwezongezo zokutya ezikhuselekileyo zokusetyenziswa", kwaye iKhomishini yeCodex Alimentarius nayo yenze imigaqo ecacileyo malunga nobunyulu bayo kunye nobubanzi bokusetyenziswa kwayo.
Ngokuphathelele uphando olunetyhefu, inani elikhulu leziphumo zovavanyo libonise ukuba i-CMC ayinatyhefu ibukhali, ayinayo i-mutagenicity, ayinayo i-teratogenicity, kwaye akukho miphumo icacileyo yomzimba kwizilwanyana okanye amalungu omzimba womntu efunyenweyo. I-CMC ngokusisiseko ayifunxwa emzimbeni kwaye ikhutshwa kakhulu kwimo yayo yokuqala, ngoko ke ayibangeli umthwalo we-metabolic okanye iqokelele ityhefu. I-FDA yase-United States iyichaze njenge-GRAS (Generally Recognised as Safe, generally recognised safe) into, evumela ukuba isetyenziswe kakhulu ekutyeni.
I-CMC yodidi lokutya inolawulo olungqongqo kwiintsalela zesinyithi esinzima, ii-chloride kunye nezinyibilikisi zendalo ngexesha lokuveliswa. Ubunyulu bayo buhlala bungaphezulu kwe-99% kwaye iye yavavanywa ngokungqongqo komgangatho wococeko. Lo gama nje isetyenziswa ngaphakathi komda omiselweyo kunye nomthamo likarhulumente okanye kwihlabathi liphela, ukutyiwa kwe-CMC kukhuselekile ngokupheleleyo.
2. Iimpawu zokusebenza ze-CMC yezinga lokutya
2.1. Imiphumo yokuqina nokuzinzisa
Imolekyuli ye-CMC inenani elikhulu lamaqela e-carboxymethyl kunye ne-hydroxyl, anokwenza iibhondi ze-hydrogen ezinamandla kunye neemolekyuli zamanzi kwaye abonise i-hydrophilicity ebalulekileyo kunye nepropathi yokudumba. Kwiinkqubo zokutya, nokuba zongezwe kumanqanaba aphantsi, zinokunyusa kakhulu i-viscosity yenkqubo, zenze isakhiwo solwelo olufanayo, kwaye ngaloo ndlela ziphucule incasa kunye nobume bemveliso. Okwangoku, i-CMC inozinzo oluhle kakhulu lwe-ionic kwaye inokugcina uzinzo lwe-viscosity kwiindawo ezine-acidic, alkaline okanye ezinetyuwa eninzi. Ihlala isetyenziswa kwiimveliso zobisi, iziselo zejusi yeziqhamo kunye neziqholo ukuthintela ukuqhekeka kunye nokuna kwemvula.
2.2. Iimpawu zokugcina amanzi kunye nokuthintela ukuna kwemvula
I-CMC ingadibana ngempumelelo nokufuma, inciphise ukufuduka kokufuma kunye nokuqandisa ukutya ngexesha lokugcina okanye lokuqandisa. Umzekelo, kukutya okuqandisiweyo kunye neempahla ezibhakiweyo, ipropathi yokugcina amanzi ye-CMC inokuthintela ukuqhekeka nokuqina, yandise ixesha lokugcinwa, kwaye igcine ukuthamba kunye nokutsha kweemveliso.
2.3. Iimpawu ze-emulsification kunye ne-suspension
I-CMC inokwenza ifilimu ye-viscoelastic kwindawo ephakathi kweoyile namanzi, iphucula uzinzo lwenkqubo ye-emulsification kwaye ithintele ioyile ukuba ingadada okanye ihlukane. Ke ngoko, isetyenziswa rhoqo kwiimveliso ezifana ne-ayisikhrim, ii-dressing zesaladi, kunye neziselo zobisi, isebenza ngokubambisana nee-emulsifiers ukuze kufezekiswe ubume obuhle nobuzinzileyo.
2.4.. Iimpawu zokwenza ifilimu kunye nokugquma
I-CMC ineempawu ezintle kakhulu zokwenza ifilimu kwaye inokwenza ifilimu ecacileyo phezu kokutya. Isetyenziselwa ukugquma iziqhamo, iilekese okanye iipowders ezikhawulezayo, idlala indima ekuthinteleni ukufuma, ukulwa ne-oxidation kunye nokulibazisa ukuwohloka. Kwipowders ezikhawulezayo kunye nepowders ezinencasa, i-CMC inokuthintela ukugaywa kwaye iphucule ukunyibilika.
2.5. Phucula incasa kunye nokuthungwa
I-CMC ingenza ukutya kube mnandi kwaye kube mnandi kwaye iphucule iimpawu ze-rheological zemveliso. Umzekelo, kwi-yogurt nakwijeli, i-CMC inokunyusa uxinano, inike ulwakhiwo oluhle lwe-texture kwaye iphucule amava okungcamla kwabathengi.
3. Amasimi okusetyenziswa kwe-CMC yokutya
Udidi lweziselo: Ukuthintela ukubola kunye nokwahlulwahlulwa kweziselo zejusi yeziqhamo kunye neziselo zeproteni, kwaye kuphucula ukugeleza kunye nencasa.
Iimveliso zobisi: Zisetyenziswa kwi-ayisikhrim nakwiyogathi ukuphucula ukuhambelana kunye nokuthintela ukwakheka kwekristale yeqhwa, ukuphucula ukugudiseka komgangatho wobisi.
Izinto ezibhakiweyo: Ziphucula ukugcinwa kwamanzi kunye nokuzinza kwentlama kwisonka nakwiikeyiki, kwaye zandise ixesha lokuthamba.
Iziqholo kunye nesosi yesoya: Zithintela ioyile namanzi ukuba zingahlukani, ziphucule ukukhazimla kunye nokunamathela eludongeni.
Iilekese nokutya okukhawulezileyo: Njengento yokugquma kunye neyokuthintela ukugabha, iphucula inkangeleko kunye nokunyibilika.
I-CMC yezinga lokutyasisixhobo sendalo esikhuselekileyo, esithembekileyo nesisebenza ngokupheleleyo kwi-polysaccharide. Iimpawu zayo ezibalaseleyo zokutyeba, ukuzinzisa, ukugcina amanzi, ukuxuba kunye nokwenza ifilimu zenza ukuba ibambe indawo engenakutshintshwa kushishino lokutya lwanamhlanje. Ngokwembono yokhuseleko, i-CMC iqinisekiswe zizikhungo ezininzi ezinegunya kwihlabathi liphela kwaye ibonwa njengesongezelelo sokutya esingenabungozi, esingena-allergies, kunye nesingasetyenziswa ixesha elide. Njengoko inkxalabo yabantu ngomgangatho wokutya kunye nempilo iqhubeka isanda, amasimi okusetyenziswa kwe-CMC yodidi lokutya aya kwanda ngakumbi, kwaye izibonelelo zayo zokusebenza kwiileyibhile ezicocekileyo, ukutya okunamafutha aphantsi kunye neemveliso ezisekwe kwizityalo nazo ziya kuqhubeka nokubonakaliswa.
