01. Izakhiwo ze-microcrystalline cellulose
I-Microcrystalline cellulose iyizinhlayiyana ezingenaphunga, ezimhlophe ngokwedlulele ezimfishane ezimfushane, usayizi wayo wezinhlayiyana ngokuvamile ungu-20-80 μm (i-microcrystalline cellulose enosayizi wezinhlayiyana zekristalu engu-0.2-2 μm iyibanga le-colloidal), kanye ne-limited degree of polymerization (LODP ) phakathi kuka-15-375;non-fibrous kodwa uketshezi ngokweqile;engancibiliki emanzini, ama-asidi acwebileyo, izincibilikisi zemvelo namafutha, ancibilike kancane futhi avuvukele ezixazululweni ze-alkali ezincibilikayo.Inokusebenza kabusha okuphezulu kwinqubo ye-carboxymethylation, i-acetylation kanye ne-esterification.Inenzuzo kakhulu ekuguquleni nasekusetshenzisweni kwamakhemikhali.
I-Microcrystalline cellulose inezici ezintathu eziyisisekelo:
1) Idigri ye-polymerization emaphakathi ifinyelela inani elilinganiselwe ledigri ye-polymerization
2) Izinga le-crystallinity liphezulu kunalelo le-cellulose eluhlaza
I-3 inokumuncwa okuqinile kwamanzi, futhi inamandla okwenza iglue ngemva kokugunda okuqinile endaweni yamanzi
02. Ukusetshenziswa kwe-microcrystalline cellulose ekudleni
2.1 Gcina ukuzinza kwe-emulsification kanye negwebu
Ukuzinza kwe-emulsion kuwumsebenzi obaluleke kakhulu we-microcrystalline cellulose.Izinhlayiya ze-cellulose ze-Microcrystalline zihlakazeka ku-emulsion ukuze zishube futhi zifake i-gel isigaba samanzi ku-emulsion yamanzi kawoyela, ngaleyo ndlela zivimbele amaconsi kawoyela ukuthi angasondeli komunye nomunye futhi aze ahlanganiswe.
Isibonelo, inani le-pH eliphansi leyogathi lingabangela kalula izingxenye eziqinile obisini ukuthi zihlangane, okubangele ukuthi i-whey ihlukane nengxube.Ukwengeza i-microcrystalline cellulose ku-yogurt kungaqinisekisa ngempumelelo ukuzinza kwemikhiqizo yobisi.Ngemva kokwengeza i-microcrystalline cellulose stabilizer ku-ayisikhilimu, ukuzinza kwayo kwe-emulsification, ukuzinza kwegwebu kanye nekhono lokuvimbela i-ice crystal kuba ngcono kakhulu, futhi uma kuqhathaniswa neziqinisi zenhlanganisela ye-polymer encibilikayo, u-ayisikhilimu uyashelela futhi uqabula kakhudlwana.
2.2 Gcina izinga lokushisa eliphakeme lizinzile
Ngesikhathi sokucubungula ukudla kwe-aseptic, kukhona kokubili izinga lokushisa eliphezulu kanye ne-viscosity ephezulu.Isitashi sizobola ngaphansi kwezimo ezinjalo, futhi ukwengeza i-microcrystalline cellulose ekudleni kwe-aseptic kungagcina izici zayo ezinhle kakhulu.Isibonelo, i-emulsion emikhiqizweni yenyama ekheniwe ingagcina ikhwalithi efanayo lapho ishisa ku-116 ° C amahora angu-3.
2.3 Thuthukisa ukuzinza koketshezi, futhi usebenze njenge-ejenti egawulayo kanye ne-ejenti elengayo
Uma iziphuzo ezisheshayo zihlakazwa kabusha emanzini, ukuhlakazeka okungalingani noma ukuzinza okuphansi kuvame ukwenzeka.Ukwengeza inani elithile le-colloidal cellulose kungakha ngokushesha isisombululo esizinzile se-colloidal, futhi ukuhlakazeka nokuzinza kuthuthukiswa kakhulu.Ukwengeza i-stabilizer esakhiwe nge-colloidal microcrystalline cellulose, isitashi kanye ne-maltodextrin kushokoledi osheshayo noma iziphuzo ze-cocoa ngeke nje kuvimbele impushana yeziphuzo ezisheshayo ukuthi ingabi manzi futhi ihlanganiswe, kodwa futhi yenza iziphuzo ezilungiselelwe ngamanzi zibe nokuzinza okuphezulu nobulili obuhlakazekayo.
2.4 Njengesigcwalisi esingenamsoco futhi sijiya, thuthukisa ukwakheka kokudla
Indawo kafulawa etholwe ngokuxuba i-microcrystalline cellulose, i-xanthan gum, ne-lecithin isetshenziswa ezimpahleni ezibhakiwe.Uma inani lokushintsha lingeqi ku-50% yenani lokuqala likafulawa osetshenzisiwe, lingagcina ukunambitheka kwasekuqaleni futhi ngokuvamile alithintwa ulimi.Ubukhulu obukhulu bezinhlayiya eziculwa yi-40 μm, ngakho-ke, i-80% yesayizi yezinhlayiyana ze-microcrystalline cellulose iyadingeka ukuba ibe <20 μm.
2.5 Ukwengezwa kuma-dessert afriziwe ukulawula ukwakheka kwekristalu yeqhwa
Ngenxa yokuba khona kwe-microcrystalline cellulose enqubweni yokuqhwaza njalo, isebenza njengesithiyo esingokomzimba, esingavimbela izinhlamvu zekristalu ukuthi zingahlangani zibe amakristalu amakhulu.Isibonelo, inqobo nje uma i-0.4-0.6% i-microcrystalline cellulose yengezwa ku-ayisikhilimu, kwanele ukuvimbela okusanhlamvu kwe-ice crystal ekukhuleni ngesikhathi sokuqandisa nokuncibilika njalo, nokuqinisekisa ukuthi ukuthungwa nokwakheka kwayo akushintshi, kanye ne-microcrystalline. izinhlayiya ze-cellulose zilungile kakhulu, Zingakhuphula ukunambitheka.Ukwengeza u-0.3%, 0.55%, kanye no-0.80% microcrystalline cellulose ku-ayisikhilimu olungiselelwe ifomula evamile yaseBrithani, i-viscosity ka-ayisikhilimu iphakeme kancane kunalokho ngaphandle kokwengeza i-microcrystalline cellulose, futhi ayinawo umthelela enanini lokuchitheka, futhi can Ithuthukisa ukuthungwa.
2.6 I-Microcrystalline cellulose isetshenziselwa ukunciphisa ama-calories
Uma isetshenziselwa ukugqoka isaladi, yehlisa ama-calories futhi wandise i-cellulose ukuze uthuthukise izakhiwo ezidliwayo.Lapho wenza izinongo zamafutha okupheka ahlukahlukene, ukwengeza i-microcrystalline cellulose kungavimbela uwoyela ukuthi ungahlukani nesoso lapho ushisiwe noma ubilisiwe.
2.7 Abanye
Ngenxa yokukhangiswa kwe-microcrystalline cellulose, ukudla okunokuqukethwe okuphezulu kwamaminerali kungatholwa ngokufakwa kwe-ion yensimbi.
