01. Iipropati ze-microcrystalline cellulose
Iselulosi yeMicrocrystalline ayivumba, icwengile ngokugqithisileyo intonga emfutshane emhlophe, ubungakanani bayo bungamasuntswana angama-20-80 μm (i-microcrystalline cellulose kunye nobungakanani bekristale obuyi-0.2-2 μm libakala le-colloidal), kunye nenqanaba lomda wepolymerization (LODP ) phakathi kwe-15-375;non-fibrous kodwa ulwelo kakhulu;enganyibilikiyo emanzini, i-acids dilute, izinyibilikisi ze-organic kunye ne-oyile, inyibilikiswe ngokuyinxenye kwaye idumbile kwizisombululo zealkali ezinyibilikayo.Ine-reactivity ephezulu kwinkqubo ye-carboxymethylation, i-acetylation kunye ne-esterification.Iluncedo kakhulu ekuguquleni imichiza kunye nokusetyenziswa.
I-Microcrystalline cellulose ineempawu ezintathu ezisisiseko:
1) Umyinge wesidanga sepolymerization ufikelela kumda wexabiso ledigri yepolymerization
2) Iqondo le-crystallinity liphezulu kuneselulosi ekrwada
I-3 inamandla okufunxa amanzi, kwaye inamandla okwenza iglu emva kokucheba okuqinileyo kwindawo yamanzi
02. Ukusetyenziswa kwe-microcrystalline cellulose ekutyeni
2.1 Gcina uzinzo lwe-emulsification kunye ne-foam
Ukuzinza kwe-emulsion ngowona msebenzi ubalulekileyo we-microcrystalline cellulose.I-Microcrystalline cellulose particles iyahlakazeka kwi-emulsion ukuze ikhulise kwaye ifake i-gel isigaba samanzi kwi-emulsion yamanzi yeoli, ngaloo ndlela ikhusela amaconsi e-oyile ukuba asondelane kwaye adibanise.
Ngokomzekelo, ixabiso eliphantsi le-pH ye-yoghurt ngokulula linokubangela ukuba izinto eziqinileyo ebisi zidibanise, zibangele ukuba i-whey yahlukane nomxube.Ukongeza i-microcrystalline cellulose kwi-yogurt inokuqinisekisa ngokufanelekileyo ukuzinza kweemveliso zobisi.Emva kokongeza i-microcrystalline cellulose stabilizer kwi-ayisikrimu, ukuzinza kwayo kwe-emulsification, ukuzinza kwe-foam kunye nokukwazi ukuthintela i-ice crystal kuphuculwe kakhulu, kwaye xa kuthelekiswa ne-soluble polymer compound stabilizers, i-ice cream ilula kwaye ihlaziya ngakumbi.
2.2 Gcina uzinzo lobushushu obuphezulu
Ngexesha lokulungiswa kokutya kwe-aseptic, kukho zombini ukushisa okuphezulu kunye ne-viscosity ephezulu.Isitashi siya kubola phantsi kweemeko ezinjalo, kwaye ukongeza i-microcrystalline cellulose kukutya kwe-aseptic kunokugcina iimpawu zayo ezintle.Ngokomzekelo, i-emulsion kwiimveliso zenyama ekheniweyo inokugcina umgangatho ofanayo xa ishushu kwi-116 ° C kwiiyure ze-3.
2.3 Ukuphucula ukuzinza kolwelo, kwaye usebenze njenge-arhente yejeli kunye ne-arhente exhomayo.
Xa iziselo ezikhawulezileyo zisasazwa kwakhona emanzini, ukusasazwa okungalinganiyo okanye ukuzinza okuphantsi kuhlala kwenzeka.Ukongeza umlinganiselo othile we-colloidal cellulose unokukhawuleza ukwenza isisombululo esizinzileyo se-colloidal, kwaye i-dispersibility kunye nokuzinza kuphuculwe kakhulu.Ukongeza i-stabilizer ehlanganiswe ne-colloidal microcrystalline cellulose, isitashi kunye ne-maltodextrin kwi-tshokoleta esheshayo okanye i-cocoa iziselo azikwazi nje ukuthintela umgubo weziselo ezikhawulezayo ukuba zibe manzi kunye ne-agglomerated, kodwa zenze iziphuzo ezilungiselelwe ngamanzi zibe nokuzinza okuphezulu kunye nokusabalalisa ngesondo.
2.4 Njengesigcwalisi esingenasondlo kunye ne-thickener, phucula isakhiwo sokutya
Indawo yomgubo efunyenwe ngokuxuba i-microcrystalline cellulose, i-xanthan gum, kunye ne-lecithin isetyenziswa kwimpahla ebhakiweyo.Xa isixa sokutshintsha singadluli kwi-50% yexabiso lokuqala lomgubo osetyenzisiweyo, linokugcina incasa yokuqala kwaye ngokuqhelekileyo ayichatshazelwa lulwimi.Ubungakanani obuninzi beengqungquthela eziculwa ngu-40 μm, ngoko ke, i-80% ye-microcrystalline cellulose particle size iyadingeka ukuba ibe <20 μm.
2.5 Ukongezwa kwizimuncumuncu ezikhenkcezisiweyo ukulawula ukumila kwekristale yomkhenkce
Ngenxa yobukho be-microcrystalline cellulose kwinkqubo yokunyibilika rhoqo, isebenza njengesithintelo somzimba, esinokuthi sithintele iinkozo zekristale ukuba zingadibanisi zibe ziikristale ezinkulu.Ngokomzekelo, nje ukuba i-0.4-0.6% i-cellulose ye-microcrystalline yongezwa kwi-ayisikrimu, yanele ukukhusela i-ice crystal grains ekunyuseni ngexesha lokukhenkcezwa rhoqo kunye nokunyibilika, kunye nokuqinisekisa ukuba ukuthungwa kwayo kunye nesakhiwo asitshintshi, kunye ne-microcrystalline. Amasuntswana e-cellulose alungile kakhulu, anokunyusa incasa.Ukongeza i-0.3%, i-0.55%, kunye ne-0.80% ye-cellulose ye-microcrystalline kwi-ayisikrimu elungiselelwe yi-formula yaseBritani eqhelekileyo, i-viscosity ye-ayisikrimu iphezulu kancinane kunoko ngaphandle kokongeza i-cellulose ye-microcrystalline, kwaye ayinayo impembelelo kwisixa sokuchithwa, kwaye iyakwazi Ukuphucula ukuthungwa.
2.6 I-Microcrystalline cellulose nayo isetyenziselwa ukunciphisa iikhalori
Ukuba isetyenziselwa ukugqoka isaladi, ukunciphisa iikhalori kunye nokwandisa i-cellulose ukuphucula iimpawu ezidliwayo.Xa usenza ioli yokupheka eyohlukeneyo, ukongeza i-microcrystalline cellulose kunokuthintela i-oyile ukuba ihlukane nesosi xa ishushu okanye ibilisiwe.
2.7 Ezinye
Ngenxa ye-adsorption ye-microcrystalline cellulose, ukutya okunomxholo ophezulu wamaminerali kunokufumaneka ngokubhengezwa kwee-ion zetsimbi.
