Carboxymethyl Cellulose (CMC) ke motsoako oa bohlokoa oa polymer o qhibilihang ka metsing o sebelisoang haholo lijong, meriana, lik'hemik'hale tsa letsatsi le letsatsi, masela le masimo a mang. Indastering ea lijo, e 'ngoe ea litšebeliso tsa bohlokoa ka ho fetisisa tsa CMC ke ho ba motenya. Li-thickeners ke sehlopha sa li-additives tse eketsang viscosity ea mokelikeli ntle le ho fetola haholo thepa e meng ea mokelikeli.
1. Sebopeho sa lik'hemik'hale le molao-motheo o teteaneng oa carboxymethyl cellulose
Carboxymethylcellulose ke karolo e tsoang ho selulose e entsoeng ka ho nkela karolo ea lihlopha tsa hydroxyl (-OH) ea cellulose ka lihlopha tsa carboxymethyl (-CH2COOH). Sebopeho sa eona sa mantlha ke ketane e iphetang ea β-D-glucose. Kenyelletso ea lihlopha tsa carboxymethyl e fa CMC hydrophilicity, e e fa matla a ho qhibiliha le matla a ho tenya ka metsing. Molao-motheo oa eona o teteaneng o ipapisitse le lintlha tse latelang:
Phello ea ho ruruha: CMC e tla ruruha ka mor'a ho monya limolek'hule tsa metsi ka metsing, ho etsa sebopeho sa marang-rang, e le hore limolek'hule tsa metsi li tšoaroe ka sebopeho sa eona, ho eketsa viscosity ea tsamaiso.
Tšusumetso ea tefiso: Lihlopha tsa carboxyl ho CMC li tla kenngoa ka metsing ho hlahisa litefiso tse mpe. Lihlopha tsena tse qosoang li tla theha electrostatic repulsion ka metsing, ho etsa hore liketane tsa limolek'hule li bulehe 'me li thehe tharollo e nang le viscosity e phahameng.
Bolelele ba ketane le mahloriso: Bolelele ba ketane le tharollo ea limolek'hule tsa CMC li tla ama phello ea eona e teteaneng. Ka kakaretso, ha boima ba limolek'hule bo phahame, ho na le viscosity e kholoanyane ea tharollo; ka nako e ts'oanang, khatello e phahameng ea tharollo, viscosity ea tsamaiso e boetse e eketseha.
Khokahano ea limolek'hule: Ha CMC e qhibiliha ka metsing, ka lebaka la ho hokahana lipakeng tsa limolek'hule le sebopeho sa sebopeho sa marang-rang, limolek'hule tsa metsi li lekanyelitsoe libakeng tse itseng, ho fella ka ho fokotseha ha metsi a tharollo, ka hona ho bonts'a phello e teteaneng.
2. Tšebeliso ea carboxymethyl cellulose indastering ea lijo
Indastering ea lijo, carboxymethylcellulose e sebelisoa haholo joalo ka motenya. Tse latelang ke tse ling tsa maemo a tloaelehileng a ts'ebeliso:
Lino le lihlahisoa tsa lebese: Ka lero la litholoana le lino tsa lactobacillus, CMC e ka eketsa viscosity ea seno, ea ntlafatsa tatso le ho lelefatsa bophelo ba sethala. Haholo-holo lihlahisoa tsa lebese tse se nang mafura le tse se nang mafura, CMC e ka nka sebaka sa karolo ea mafura a lebese le ho ntlafatsa sebopeho le botsitso ba sehlahisoa.
Li-sauces le li-condiments: Litabeng tsa salate, tamati sauce le soy sauce, CMC e sebetsa e le ntho e teteaneng le e emisang ho ntlafatsa ho tšoana ha sehlahisoa, ho qoba delamination, le ho etsa hore sehlahisoa se tsitse.
Ice cream le lino tse batang: Ho eketsa CMC ho ice cream le lino tse batang ho ka ntlafatsa sebopeho sa sehlahisoa, ho etsa hore se be matla le ho feta, ho thibela ho thehoa ha likristale tsa leqhoa le ho ntlafatsa tatso.
Bohobe le lihlahisoa tse apeiloeng: Lihlahisoang tse halikiloeng tse kang bohobe le likuku, CMC e sebelisoa e le sentlafatsi sa hlama ho matlafatsa ho ata ha hlama, ho etsa hore bohobe bo be bonolo, le ho lelefatsa sethala sa bophelo.
3. Lisebelisoa tse ling tse teteaneng tsa carboxymethyl cellulose
Ntle le lijo, hangata carboxymethylcellulose e sebelisoa e le motenya oa meriana, litlolo, lik'hemik'hale tsa letsatsi le letsatsi le liindasteri tse ling. Ka mohlala:
Indasteri ea meriana: Meriana, CMC e atisa ho sebelisoa ho tenya li-syrups, capsules, le matlapa, e le hore meriana e be le liphello tse ntle tsa ho bōptjoa le ho senyeha, 'me e ka ntlafatsa botsitso ba meriana.
Litlolo le lik'hemik'hale tsa letsatsi le letsatsi: Ka lik'hemik'hale tsa letsatsi le letsatsi tse kang sesepa sa meno, shampoo, gel ea ho hlapa, joalo-joalo, CMC e ka eketsa ts'ebetso ea sehlahisoa, ea ntlafatsa phihlelo ea tšebeliso, 'me ea etsa hore pente e ts'oane le e tsitsitseng.
4. Tšireletseho ea carboxymethyl cellulose
Tšireletseho ea carboxymethylcellulose e netefalitsoe ke lithuto tse ngata. Kaha CMC e nkiloe ho selulose ea tlhaho 'me ha e siloe le ho kenngoa' meleng, hangata ha e na phello e mpe bophelong ba motho. Ka bobeli Mokhatlo oa Lefatše oa Bophelo (WHO) le Komiti e Kopanetsoeng ea Setsebi mabapi le Li-additives tsa Lijo (JECFA) li e khetholla e le tlatsetso e sireletsehileng ea lijo. Ka tekanyo e lekaneng, CMC ha e hlahise chefo mme e na le litlamorao tse itseng tsa ho tlotsa le ho hlatsa mala. Leha ho le joalo, ho ja haholo ho ka baka mathata a ka mpeng, ka hona, litekanyetso tse behiloeng tsa litekanyetso li lokela ho lateloa ka thata tlhahisong ea lijo.
5. Melemo le melemo ea carboxymethylcellulose
Carboxymethylcellulose e na le melemo le mefokolo ea eona joalo ka motenya:
Melemo: CMC e na le ho qhibiliha ha metsi hantle, botsitso ba mocheso le botsitso ba lik'hemik'hale, e hanyetsa asiti le alkali, 'me ha e fokole habonolo. Sena se lumella hore e sebelisoe libakeng tse fapaneng tsa ho sebetsa.
Mefokolo: CMC e kanna ea ba le viscous haholo maemong a holimo mme ha ea lokela lihlahisoa tsohle. CMC e tla nyenyefatsa tikolohong e nang le asiti, e leng se tla fella ka ho fokotseha ha phello ea eona e teteaneng. Ho hlokahala tlhokomeliso ha u e sebelisa linong tse nang le asiti kapa lijong.
Joaloka motenya oa bohlokoa, carboxymethylcellulose e sebelisoa haholo lijong, meriana, litlolo le masimo a mang ka lebaka la ho qhibiliha ha metsi, ho teteaneng le botsitso. Tšireletso ea eona e phahameng ka ho fetisisa le ts'ireletso li etsa hore e be tlatsetso e sebelisoang hangata indastering ea kajeno. Leha ho le joalo, ts'ebeliso ea CMC e boetse e hloka ho laoloa ka mahlale ho latela litlhoko tse ikhethileng le litekanyetso tsa litekanyetso ho netefatsa ts'ebetso ea eona le polokeho ea lijo.
