Selulose ea microcrystalline ke eng?

Microcrystalline cellulose (MCC), haholo-holo e entsoeng ka β- The straight-chain polysaccharide e kopantsoeng le 1,4-glucoside bond [1] ke phofshoana e tšoeu, e sa nkhang le e sa latsoeheng e entsoeng ka likaroloana tse nyenyane tse bopehileng joaloka thupa kapa phofo. e ka phallang ka bolokolohi le hydrolyze selulose ea tlhaho ho isa tekanyong e lekanyelitsoeng ea polymerization (LODP) ka mor'a ho hlapolla acid hydrolysis.
Ka kakaretso likhoele tsa semela, microcrystalline cellulose e etsa hoo e ka bang 70%, 'me e' ngoe 30% ke amorphous. Selulose ea Microcrystalline e sebelisoa haholo ho tsa meriana, litlolo, lijo le liindasteri tse ling. Mefuta e fapaneng ea boholo ba likaroloana le likahare tsa metsi li na le litšobotsi tse fapaneng le mefuta ea ts'ebeliso.

Selulose ea microcrystalline e fumanoa ho selulose ea semela ka mor'a hydrolysis, 'me mokhoa o lekantsoeng ke: hydrolysis ea dilute inorganic acid solution α- Cellulose, moo α- Cellulose e ka etsoang ho tloha selulose makhasi a limela tsa cellulose. Selulose ea hydrolyzed e ea tlhotloa, ea hloekisoa, 'me seretse se omisitsoe ho etsa likaroloana tse porous tse nang le boholo ba likaroloana tse ajoang haholo.

Tšebeliso e sebetsang: adsorbent; Moemeli oa ho emisa; Thinners bakeng sa matlapa le capsules; Disintegrator bakeng sa matlapa
Sehlopha sa lihlahisoa: cellulose | li-excipients tsa meriana, li-additives tsa lijo
Lihlahisoa tsa lihlahisoa: phofo e tšoeu kapa e batlang e le tšoeu, e se nang monko ebile e sa latsoehe. Sehlahisoa sena ha se qhibilihe ka metsing, ethanol, acetone kapa toluene.

Mosebetsi oa microcrystalline cellulose

Selulose ea microcrystalline e ka tsitsisa foam le emulsion, haholo-holo nakong ea ts'ebetso e phahameng ea mocheso; Ho etsa gel ka sebopeho sa mafura; ho ntlafatsa ho hanyetsa mocheso oa pectin le gel ea starch; Ntlafatsa ho khomarela; Kenya sebaka sa mafura le oli 'me u laole khōlo ea kristale ea leqhoa. Lebaka leo ka lona cellulose ea microcrystalline e ka tsitsang emulsion le foam ke hore cellulose ea microcrystalline e adsorbed holim'a sebopeho mme e matlafatsa moeli oa sefahleho sa sefahleho. Microcrystalline cellulose ke motsoako o tloaelehileng oa ice cream e mafura a tlase le lihlahisoa tse ling tse nang le serame.

Ka indasteri ea meriana, cellulose ea microcrystalline e atisa ho sebelisoa e le adsorbent, suspension aid, diluent le disintegrant. Microcrystalline cellulose e sebelisoa haholo litokisetsong tsa meriana, haholo-holo e le ntho e hlapollang le e khomarelang matlapeng a molomo le li-capsules. E ka sebelisoa eseng feela bakeng sa granulation e metsi empa hape le bakeng sa ho hatisa letlapa le omeletseng. E boetse e na le litlamorao tse itseng tsa ho tlotsa le ho qhala, tse thusang haholo ho lokiseng matlapa. E na le melemo e latelang ho feta starch kapa derivatives ea starch:
(1) Ho bonolo ho arohana, ke hore, moriana o bonolo ho senyeha ka mor'a ho kena ka mpeng 'me o kenngoa ke' mele.
(2) Ha ho bonolo ho hlobola hobane selulose ke tlhophiso ea tsoekere ea β Type A, athe starch ke ea α Type configuration. Ka kakaretso, amylase ha e hlase cellulose.
(3) Cellulose ha e monoe ke ’mele oa motho, ’me ha ho bonolo ho itšoara ka lithethefatsi tse laetsoeng, kahoo e sireletsehile haholoanyane. Bothata ba eona ke hore theko e ka lehlakoreng le phahameng.

Tšebeliso ea microcrystalline cellulose

Indastering ea lijo, selulose ea microcrystalline ke sesebelisoa sa motheo sa lijo - fiber ea lijo, e leng tlatsetso e nepahetseng ea lijo tsa bophelo bo botle. E ka boloka botsitso ba emulsification le foam; E ka boloka botsitso ba mocheso o phahameng le ho ntlafatsa botsitso ba mokelikeli, hape e ka sebelisoa e le tlatsetso ea phepo e nepahetseng le e teteaneng. Lihlahisoa tse ngata tsa nama, lijo tse hatselitsoeng ka potlako le ice cream lia eketsoa.
Indastering ea litlolo, cellulose ea microcrystalline e sebelisoa e le ntho e kopanyang mefuta e sa tšoaneng ea litlolo, phekolo ea letlalo le lihlahisoa tsa tlhokomelo, hammoho le ho etsa lihlahisoa tsa ho hloekisa. E kopanya mesebetsi ea ho tlatsa, e teteaneng le emulsification, 'me e na le bokhoni bo botle ba emulsification bakeng sa lintho tse mafura.
