Hydrocolloids: methylcellulose
Methylcellulose ke mofuta oa hydrocolloid, e tsoang ho selulose, e leng polima ea tlhaho e fumanehang maboteng a lisele tsa semela. Methylcellulose e entsoe ka phetoho ea lik'hemik'hale ea selulose, haholo-holo ka ho kenya lihlopha tsa hydroxyl le lihlopha tsa methyl (-CH3). Phetoho ena e fana ka thepa e ikhethang ho methylcellulose, e etsa hore e sebelisoe lits'ebetsong tse fapaneng tsa indasteri.
Lintho tse molemo tsa methylcellulose:
- Ho qhibiliha ha Metsi: Methylcellulose e qhibiliha ka metsing a batang, e etsa litharollo tse hlakileng, tsa viscous kapa li-gel ho itšetlehile ka mahloriso. E bonts'a boits'oaro ba pseudoplastic, ho bolelang hore viscosity ea eona e fokotseha ka sekhahla sa ho kuta.
- Thickening le Gelling: Methylcellulose e nkoa e le ea bohlokoa ka lebaka la thepa ea eona e teteaneng le ea gelling, e etsang hore e tšoanelehe ho sebelisoa e le motenya, stabilizer, kapa gelling agent lijong, meriana le lihlahisoa tsa tlhokomelo ea botho.
- Ho Etsa Lifilimi: Ha o omisitsoe, methylcellulose e etsa lifilimi tse bonolo le tse hlakileng. Thepa ena e sebelisoa lits'ebetsong tse fapaneng, ho kenyeletsoa lifilimi tse jeoang le likoahelo bakeng sa lihlahisoa tsa lijo, hammoho le litlamong tsa meriana le tsa litlolo.
- Ts'ebetso ea Bokaholimo: Methylcellulose e ka fokotsa tsitsipano ea bokaholimo le ho ntlafatsa thepa ea ho kolobisa, ea e etsa hore e be molemo mefuteng e joalo ka litlolo, lipente le maro a ho cheka.
Lisebelisoa tsa methylcellulose:
- Indasteri ea Lijo: Methylcellulose e atisa ho sebelisoa e le ntho e teteaneng, e tsitsitseng, kapa emulsifier lihlahisoa tsa lijo. E ntlafatsa sebopeho, viscosity, le molomo oa li-sauces, li-dressings, li-dessert le lintho tse halikiloeng. E boetse e sebelisoa ho bakang ntle le gluten joalo ka setlamo le se bolokang mongobo.
- Meriana ea Meriana: Mekhatlong ea meriana, methylcellulose e sebetsa e le se tlamang, se senyang, kapa se laolang ho lokolloa ka matlapa le li-capsules. E sebelisoa ho ntlafatsa thepa ea phallo ea phofo, ho laola litekanyetso tsa ho lokolloa ha lithethefatsi, le ho matlafatsa bioavailability ea lithethefatsi tse sa qhibiliheng hantle.
- Lihlahisoa tsa Tlhokomelo ea Motho: Methylcellulose e fumanoa lihlahisoa tse fapaneng tsa tlhokomelo ea motho le litlolo, ho kenyeletsoa li-shampoo, litlolo, litlolo le li-gel. E sebetsa joalo ka motenya, stabilizer, kapa moemeli oa ho etsa lifilimi, e fana ka sebopeho se lakatsehang, botsitso le thepa ea rheological.
- Lisebelisoa tsa Kaho: Methylcellulose e sebelisoa linthong tsa kaho tse kang motsoako oa li-drywall, seretse le li-adhesives tsa lithaele. E ntlafatsa ho sebetsa, ho khomarela, le ho boloka metsi lihlahisoa tsena.
- Lisebelisoa tsa Indasteri: Methylcellulose e fumana lits'ebetso lits'ebetsong tsa indasteri, ho kenyeletsoa ho etsa pampiri, masela le ho roala. E sebetsa joalo ka motenya, se tlamella, kapa se fetola bokaholimo, se ntlafatsa ts'ebetso le litšobotsi tsa ts'ebetso ea lisebelisoa tse fapaneng.
Melemo ea methylcellulose:
- Biodegradability: Methylcellulose e tsoa mehloling ea limela e nchafalitsoeng 'me e ka senyeha, e etsa hore e boloke tikoloho le ho tšoarella.
- Ha e na Chefo ebile e Sireletsehile: Methylcellulose ka kakaretso e nkuoa e bolokehile hore e ka sebelisoa le ho sebelisoa lijong, meriana le lihlahisoa tsa tlhokomelo ea motho. E na le chefo e tlase mme ha e tsejoe e baka litlamorao tse mpe tsa bophelo bo botle.
- Ho feto-fetoha ha maemo: Methylcellulose e fana ka mefuta e mengata ea ts'ebetso 'me e ka lokisoa ho latela litlhoko tse khethehileng tsa kopo ka ho fetola litekanyo tse kang boima ba limolek'hule, tekanyo ea ho fetola le ho tsepamisa mohopolo.
- Ho lumellana: Methylcellulose e lumellana le mefuta e sa tšoaneng ea metsoako le metsoako, e etsa hore e loketse ho sebelisoa ka mokhoa o rarahaneng le mekhoa e mengata ea likarolo.
Ka bokhutšoanyane, methylcellulose ke hydrocolloid e feto-fetohang le ea bohlokoa e nang le lisebelisoa tse ngata ho pholletsa le indasteri. Thepa ea eona e ikhethang, e kenyelletsang ho qhibiliha ha metsi, ho teteka, ho etsa gelling, le bokhoni ba ho etsa lifilimi, e etsa hore e be motsoako oa bohlokoa mefuteng e mengata ea lijo, meriana, tlhokomelo ea botho le lihlahisoa tsa indasteri.
