Thepa le Lisebelisoa tsa Microcrystalline Cellulose

01. Thepa ea microcrystalline cellulose

Microcrystalline cellulose ke ntho e sa nkheng, e ntle ka ho fetesisa e tšoeu ea molamu o mokhuts'oane, boholo ba eona hangata ke 20-80 μm (selulose ea microcrystalline e nang le boholo ba kristale ea 0.2-2 μm ke sehlopha sa colloidal), le tekanyo e lekanyelitsoeng ea polymerization (LODP). ) pakeng tsa 15-375; e se nang li-fibrous empa e le metsi a feteletseng; ha e qhibilihe ka metsing, e hlapolla li-acids, li-solvents le oli, e qhibilihisitsoeng hanyenyane 'me e ruruhile ka metsoako ea alkali e hlapollang. E na le reactivity e phahameng ts'ebetsong ea carboxymethylation, acetylation le esterification. E molemo haholo bakeng sa phetoho ea lik'hemik'hale le ho sebelisoa.

Microcrystalline cellulose e na le litšobotsi tse tharo tsa motheo:

1) Kakaretso ea tekanyo ea polymerization e fihla moeling oa tekanyo ea tekanyo ea polymerization

2) Tekanyo ea crystallinity e phahame ho feta ea cellulose e tala

3 e na le ho monya metsi ka matla, 'me e na le bokhoni ba ho etsa sekhomaretsi ka mor'a ho kuta ka matla sebakeng sa metsi

02. Ho sebelisoa ha cellulose ea microcrystalline lijong

2.1 Boloka botsitso ba emulsification le foam

Emulsion botsitso ke mosebetsi oa bohlokoa ka ho fetisisa oa selulose ea microcrystalline. Likaroloana tsa selulose tsa microcrystalline li qhalakantsoeng ka emulsion ho teteaneng le ho tšela karolo ea metsi ka har'a emulsion ea metsi a oli, ka hona ho thibela marotholi a oli ho atamelana esita le ho kopanya.

Mohlala, boleng bo tlase ba pH ba yoghurt bo ka baka habonolo likarolo tse tiileng tsa lebese ho hoama, ho etsa hore whey e arohane le motsoako. Ho eketsa cellulose ea microcrystalline ho yogurt ho ka netefatsa botsitso ba lihlahisoa tsa lebese. Ka mor'a ho eketsa microcrystalline cellulose stabilizer ho ice cream, botsitso ba eona ba emulsification, botsitso ba foam le bokhoni ba ho thibela kristale ea leqhoa bo ntlafatsoa haholo, 'me ha bo bapisoa le li-stabilizer tsa motsoako oa polymer, ice cream e bonolo ebile e khatholla haholoanyane.

2.2 Boloka botsitso ba mocheso o phahameng

Nakong ea ts'ebetso ea lijo tsa aseptic, ho na le mocheso o phahameng le viscosity e phahameng. Starch e tla bola tlas'a maemo a joalo, 'me ho eketsa cellulose ea microcrystalline lijong tsa aseptic ho ka boloka litšobotsi tsa eona tse ntle. Ka mohlala, emulsion ea lihlahisoa tsa nama e entsoeng ka makotikoting e ka boloka boleng bo tšoanang ha e futhumala ka 116 ° C ka lihora tse 3.

2.3 Ntlafatsa botsitso ba mokelikeli, 'me u sebetse joalo ka mokelikeli le moemeli oa ho emisa

Ha lino tse tahang hang-hang li qhalakanngoa hape ka metsing, ho hasana ho sa lekaneng kapa botsitso bo fokolang hangata ho etsahala. Ho eketsa palo e itseng ea cellulose ea colloidal ho ka etsa ka potlako tharollo e tsitsitseng ea colloidal, 'me ho senyeha le botsitso ho ntlafatsoa haholo. Ho eketsa stabilizer e entsoeng ka colloidal microcrystalline cellulose, starch le maltodextrin ho chokolete ea hang-hang kapa lino tsa cocoa ho ke ke ha thibela feela phofo ea lino tse tahang hang-hang hore e se ke ea e-ba metsi le e kopantsoeng, empa hape e etsa hore lino tse lokiselitsoeng ka metsi li be le botsitso bo phahameng le ho qhalakanngoa ho kopanela liphate.

2.4 Joalo ka setlolo se se nang phepo le setenya, ntlafatsa sebopeho sa lijo

Phapanyetsano ea phofo e fumanoeng ka ho kopanya cellulose ea microcrystalline, xanthan gum le lecithin e sebelisoa linthong tse halikiloeng. Ha palo ea ho kenya sebaka e sa fete 50% ea palo ea pele ea phofo e sebelisitsoeng, e ka boloka tatso ea pele 'me ka kakaretso ha e amehe ke leleme. Boholo bo boholo ba likaroloana tse binoang ke 40 μm, ka hona, 80% ea boholo ba karoloana ea microcrystalline cellulose e hlokeha ho ba <20 μm.

2.5 Keketso ho li-dessert tse leqhoa ho laola sebopeho sa kristale ea leqhoa

Ka lebaka la ho ba teng ha selulose ea microcrystalline ts'ebetsong ea ho qhibiliha khafetsa, e sebetsa e le tšitiso ea 'mele, e ka thibelang lithollo tsa kristale hore li se ke tsa kopana ho ba likristale tse kholo. Ka mohlala, ha feela 0.4-0.6% microcrystalline cellulose e kenngoa ka ice cream, ho lekane ho thibela lithollo tsa kristale ea leqhoa hore li se ke tsa eketseha nakong ea serame le ho qhibiliha khafetsa, le ho etsa bonnete ba hore sebopeho sa eona le sebopeho sa eona ha se fetohe, le microcrystalline. likaroloana tsa cellulose li ntle haholo, li ka eketsa tatso. Ho eketsa 0.3%, 0.55%, le 0.80% microcrystalline cellulose ho ice cream e lokiselitsoeng ka mokhoa o tloaelehileng oa Borithane, viscosity ea ice cream e phahame hanyenyane ho feta ntle le ho eketsa cellulose ea microcrystalline, 'me ha e na phello ho bongata ba ho qhalana,' e ka ntlafatsa sebopeho.

2.6 Microcrystalline cellulose e boetse e sebelisoa ho fokotsa lik'hilojule

Haeba e sebelisoa ho apara salate, fokotsa lik'hilojule le ho eketsa cellulose ho ntlafatsa thepa e jeoang. Ha u etsa litlolo tse fapaneng tsa oli e phehang, ho eketsa cellulose ea microcrystalline ho ka thibela oli hore e se ke ea arohana le soso ha e futhumatsoa kapa e phehiloe.

2.7 Tse ling

Ka lebaka la ho ata ha cellulose ea microcrystalline, lijo tse nang le liminerale tse ngata li ka fumanoa ka ho kenngoa ha li-ion tsa tšepe.
