Carboxymethyl Cellulose (CMC) ndi chinthu chofunikira chosungunuka m'madzi cha polima chomwe chimagwiritsidwa ntchito kwambiri muzakudya, mankhwala, mankhwala atsiku ndi tsiku, nsalu ndi zina. M'makampani azakudya, chimodzi mwazinthu zofunikira kwambiri za CMC ndikulimbitsa thupi. Thickeners ndi gulu la zowonjezera zomwe zimawonjezera kukhuthala kwamadzimadzi popanda kusintha kwambiri zina zamadzimadzi.
1. Kapangidwe ka mankhwala ndi mfundo yokhutiritsa ya carboxymethyl cellulose
Carboxymethylcellulose ndi chochokera ku cellulose yomwe imapangidwa posintha gawo lamagulu a hydroxyl (-OH) a cellulose ndi magulu a carboxymethyl (-CH2COOH). Chigawo chake choyambirira ndi unyolo wobwereza wa β-D-glucose. Kukhazikitsidwa kwa magulu a carboxymethyl kumapereka CMC hydrophilicity, ndikupangitsa kuti ikhale yosungunuka bwino komanso kukhuthala m'madzi. Kukula kwake kumatengera mfundo zotsatirazi:
Kutupa zotsatira: CMC pathupi pambuyo kuyamwa madzi mamolekyu m'madzi, kupanga dongosolo maukonde, kuti mamolekyu madzi anagwidwa mu dongosolo lake, kuwonjezera mamasukidwe akayendedwe a dongosolo.
Zotsatira: Magulu a carboxyl mu CMC adzakhala ndi ayoni pang'ono m'madzi kuti apange ndalama zoyipa. Magulu operekedwawa adzapanga ma electrostatic repulsion m'madzi, zomwe zimapangitsa kuti maunyolo a cell awoneke ndikupanga njira yokhala ndi kukhuthala kwakukulu.
Kutalika kwa unyolo ndi kuyika kwake: Kutalika kwa unyolo ndi kusungunuka kwa mamolekyu a CMC kudzakhudza kukula kwake. Nthawi zambiri, kuchuluka kwa kulemera kwa maselo, kumapangitsanso kukhuthala kwa yankho; panthawi imodzimodziyo, kuwonjezereka kwa njira yothetsera vutoli, kukhuthala kwa dongosolo kumawonjezekanso.
Kulumikizana kwa mamolekyu: Pamene CMC imasungunuka m'madzi, chifukwa cha kugwirizana pakati pa mamolekyu ndi mapangidwe a ma netiweki, mamolekyu amadzi amangokhala kumadera enaake, zomwe zimapangitsa kuchepa kwa madzi amadzimadzi, motero kusonyeza thickening zotsatira.
2. Kugwiritsa ntchito carboxymethyl cellulose m'makampani azakudya
M'makampani azakudya, carboxymethylcellulose imagwiritsidwa ntchito ngati thickener. Zotsatirazi ndi zina mwazochitika zogwiritsira ntchito:
Zakumwa ndi mkaka: Mu timadziti ta zipatso ndi zakumwa za lactobacillus, CMC imatha kuwonjezera kukhuthala kwa chakumwacho, kuwongolera kukoma ndikukulitsa moyo wa alumali. Makamaka mumkaka wopanda mafuta komanso wopanda mafuta, CMC imatha kusintha gawo lamafuta amkaka ndikuwongolera mawonekedwe ndi kukhazikika kwa mankhwalawa.
Msuzi ndi zokometsera: Muzovala za saladi, msuzi wa phwetekere ndi msuzi wa soya, CMC imagwira ntchito ngati chowonjezera komanso kuyimitsa kuti ikhale yofananira, kupewa delamination, ndikupangitsa kuti chinthucho chikhale chokhazikika.
Ayisikilimu ndi zakumwa zoziziritsa kukhosi: Kuonjezera CMC ku ayisikilimu ndi zakumwa zoziziritsa kukhosi kumatha kusintha kapangidwe kazinthuzo, kuzipangitsa kukhala zolimba komanso zotanuka kwambiri, kuteteza mapangidwe a ayezi ndikuwongolera kukoma.
Mkate ndi Zophika Zophika: Pazinthu zophikidwa monga mkate ndi makeke, CMC imagwiritsidwa ntchito ngati chowonjezera cha mtanda kuti chiwonjezeke kukula kwa mtanda, kupangitsa mkate kukhala wofewa, ndikuwonjezera moyo wa alumali.
3. Ntchito zina zokulitsa za carboxymethyl cellulose
Kuwonjezera pa chakudya, carboxymethylcellulose nthawi zambiri amagwiritsidwa ntchito ngati thickener mu mankhwala, zodzoladzola, mankhwala tsiku ndi tsiku ndi mafakitale ena. Mwachitsanzo:
Makampani opanga mankhwala: M'zamankhwala, CMC nthawi zambiri imagwiritsidwa ntchito kulimbitsa ma syrups, makapisozi, ndi mapiritsi, kuti mankhwalawo akhale ndi zotsatira zabwino zowumba ndi kupasuka, komanso amathandizira kukhazikika kwamankhwala.
Zodzoladzola ndi mankhwala atsiku ndi tsiku: Pamankhwala atsiku ndi tsiku monga mankhwala otsukira mano, shampu, gel osamba, ndi zina zambiri, CMC imatha kukulitsa kusasinthika kwazinthuzo, kupititsa patsogolo luso logwiritsa ntchito, ndikupanga phala yunifolomu komanso yokhazikika.
4. Chitetezo cha carboxymethyl cellulose
Chitetezo cha carboxymethylcellulose chatsimikiziridwa ndi maphunziro angapo. Popeza CMC imachokera ku cellulose yachilengedwe ndipo sichigayidwa ndikulowa m'thupi, nthawi zambiri sichikhala ndi zotsatira zoyipa pa thanzi la munthu. Onse a World Health Organisation (WHO) ndi Joint Expert Committee on Food Additives (JECFA) amachiyika ngati chowonjezera chotetezeka cha chakudya. Pa mlingo wololera, CMC sipanga zochitika zapoizoni ndipo imakhala ndi zodzoladzola zina komanso zotsekemera pamatumbo. Komabe, kudya mopitirira muyeso kungayambitse kupweteka kwa m'mimba, motero miyezo yoperekedwa ya mlingo iyenera kutsatiridwa kwambiri pakupanga chakudya.
5. Ubwino ndi kuipa kwa carboxymethylcellulose
Carboxymethylcellulose ili ndi zabwino ndi zofooka zake ngati chowonjezera:
Ubwino: CMC ili ndi kusungunuka kwamadzi kwabwino, kukhazikika kwamafuta ndi kukhazikika kwamankhwala, ndi asidi ndi alkali kugonjetsedwa, ndipo sikuwonongeka mosavuta. Izi zimapangitsa kuti zigwiritsidwe ntchito m'malo osiyanasiyana opangira.
Zoyipa: CMC imatha kukhala yowoneka bwino kwambiri komanso siyoyenera pazinthu zonse. CMC idzawonongeka m'malo a acidic, zomwe zimapangitsa kuchepa kwa kukhuthala kwake. Kusamala ndikofunikira mukamagwiritsa ntchito zakumwa za acidic kapena zakudya.
Monga chowonjezera chofunikira, carboxymethylcellulose imagwiritsidwa ntchito kwambiri muzakudya, mankhwala, zodzoladzola ndi zina zambiri chifukwa cha kusungunuka kwake kwamadzi, kukhuthala komanso kukhazikika. Kukula kwake kokulirapo komanso chitetezo kumapangitsa kuti ikhale yowonjezera yomwe imagwiritsidwa ntchito kwambiri m'makampani amakono. Komabe, kugwiritsa ntchito CMC kuyeneranso kuyendetsedwa mwasayansi molingana ndi zosowa zenizeni ndi miyezo ya mlingo kuti zitsimikizire kukhathamiritsa kwa magwiridwe ake komanso chitetezo cha chakudya.
