9. Melemo le bofokoli ba MHEC
Melemo:
Ho feto-fetoha ha maemo: MHEC e na le mesebetsi e mengata e kang ho teteka, ho boloka metsi, ho emisa, emulsification, joalo-joalo, 'me e na le mefuta e mengata ea likopo.
E na le botsoalle ho tikoloho: MHEC ke ntho e ka senyehang habonolo e nang le tšilafalo e fokolang ea tikoloho.
Botsitso bo matla: E bontsha botsitso bo botle tlasa pH le maemo a mocheso a fapaneng.
Mefokolo:
Litšenyehelo tse phahameng: Ha li bapisoa le li-thickeners tse ling tsa setso, theko ea tlhahiso ea MHEC e phahame.
Ho Ikamahanya le Lik'hemik'hale Tse Ling: Ka mekhoa e itseng, MHEC e ka 'na ea ba le mathata a ho lumellana le lik'hemik'hale tse itseng.
Ka lebaka la thepa ea eona e ntle ea 'mele le ea lik'hemik'hale, methyl hydroxyethyl cellulose (MHEC) e sebelisoa haholo liindastering tse ngata tse kang kaho, liaparo, peterole, lijo, meriana le ho etsa pampiri. E le motenya, mokelikeli oa metsi, binder le stabilizer, e fana ka ts'ehetso ea ts'ebetso ea bohlokoa bakeng sa lihlahisoa le lits'ebetso libakeng tse fapaneng. Leha ho le joalo, lits'ebetsong tse sebetsang, ho lumellana ha eona le lisebelisoa tse ling le lintlha tsa litšenyehelo le tsona li tlameha ho nahanoa. Nakong e tlang, ka tsoelo-pele ea theknoloji le liphetoho tlhokahalong ea 'maraka, libaka tsa kopo tsa MHEC li ka atolosoa le ho feta.
