01. Qalabka microcrystalline cellulose
Microcrystalline cellulose waa ur aan ur lahayn, aad u fiican oo cad cad oo gaaban oo jilicsan, cabbirkeeda guud ahaan waa 20-80 μm (microcrystalline cellulose oo leh cabbirka qayb ka mid ah 0.2-2 μm waa darajada kolloidal), iyo heerka xaddidan ee polymerization (LODP) ) inta u dhaxaysa 15-375; aan fibre ahayn laakiin aad u dareere ah; aan lagu milmi karin biyaha, asiidhyada milo, dareerayaasha organic iyo saliidaha, qayb ahaan milmay oo bararsan xalalka alkali ee milan. Waxay leedahay falcelin sare oo ku saabsan habka karboxymethylation, acetylation iyo esterification. Aad bay faa'iido ugu leedahay wax ka beddelka kiimikada iyo ka faa'iidaysiga.
Microcrystalline cellulose waxay leedahay saddex sifo oo aasaasi ah:
1) Celceliska darajada polymerization-ka waxay gaartaa xadka qiimaha shahaadada polymerization
2) Heerka crystallinity ayaa ka sarreeya kan cellulose ceeriin
3 wuxuu leeyahay nuugista biyaha xooggan, wuxuuna awood u leeyahay inuu sameeyo koollo ka dib xiirid xooggan ee dhexdhexaadka biyaha
02. Codsiga microcrystalline cellulose ee cuntada
2.1 Ilaali xasiloonida emulsification iyo xumbo
Dejinta emulsion waa shaqada ugu muhiimsan ee cellulose microcrystalline. Qaybaha cellulose microcrystalline ayaa ku kala firirsan emulsion si ay u dhumuc iyo jel wajiga biyaha ee emulsion saliid-biyaha ah, taas oo ka hortagaysa dhibco saliid ka midba midka kale u soo dhawaado iyo xataa isu geyn.
Tusaale ahaan, qiimaha pH ee hooseeya ee caano fadhigu wuxuu si fudud u keeni karaa in qaybaha adag ee caanaha ku jira ay xinjiroobaan, taasoo keenaysa in caanaha ay ka soocaan isku dar ah. Ku darista microcrystalline cellulose ee caano fadhi waxay si wax ku ool ah u xaqiijin kartaa xasilloonida waxyaabaha caanaha laga sameeyo. Ka dib marka lagu daro stabilizer microcrystalline cellulose ee jalaatada, xasiloonida emulsification, xasiloonida xumbo iyo awoodda ka hortagga barafka ayaa si weyn loo wanaajiyey, marka la barbar dhigo xasiliyeyaasha isku-dhafka polymer-ka ee biyaha-milmi leh, jalaatada ayaa fudud oo soo kicinaysa.
2.2 Ilaali xasiloonida heerkulka sare
Inta lagu jiro habaynta cuntada aseptic, waxaa jira labadaba heerkul sare iyo viscosity sare. Istaarjku wuxuu ku dumi doonaa xaaladahan oo kale, iyo ku darida cellulose microcrystalline cuntada aseptic waxay ilaalin kartaa sifooyinkeeda ugu fiican. Tusaale ahaan, emulsion-ka ku jira hilibka qasacadaysan wuxuu ilaalin karaa isla tayada marka lagu kululeeyo 116 ° C ilaa 3 saacadood.
2.3 Hagaajinta xasilloonida dareeraha, oo u dhaqan sidii wakiilka jeling iyo wakiilka joojinta
Marka cabitaannada degdega ah lagu kala firdhiyo biyaha, kala firdhisanaan aan sinnayn ama xasillooni hoose ayaa badanaa dhacda. Ku darista xaddi gaar ah oo cellulose kolloidal ah waxay si dhakhso ah u samayn kartaa xal kolloid ah oo deggan, kala firdhinta iyo xasilloonida ayaa si weyn loo hagaajiyaa. Ku darista stabilizer oo ka kooban kolloidal microcrystalline cellulose, istaarijka iyo maltodextrin si shukulaatada degdega ah ama cabitaanka kookaha kaliya kama hortagi karto budada cabitaanada degdega ah inay qoyan oo ay sii xumaato, laakiin sidoo kale waxay sameeyaan cabitaanada biyaha lagu diyaariyo waxay leeyihiin xasilooni sare iyo galmo kala firdhisan.
2.4 Sida buuxine aan nafaqo lahayn oo dhumucdiisuna, wanaaji qaabka cuntada
Beddelka burka ee lagu helo isku dhafka microcrystalline cellulose, xanthan xanjo, iyo lecithin ayaa loo isticmaalaa alaabta la dubay. Marka qadarka beddelku aanu ka badnayn 50% ee caddadka asalka ah ee daqiiqda ee la isticmaalay, waxay ilaalin kartaa dhadhanka asalka ah oo guud ahaan ma saameynayo carrabka. Cabbirka ugu badan ee qaybaha gabayga waa 40 μm, sidaas darteed, 80% ee cabbirka qaybinta microcrystalline cellulose ayaa looga baahan yahay inay noqdaan <20 μm.
2.5 Ku darida macmacaanka la qaboojiyey si loo xakameeyo samaynta barafka
Sababtoo ah joogitaanka microcrystalline cellulose ee habka barafaynta-dhalaalaya ee joogtada ah, waxay u shaqeysaa sidii caqabad jireed, taas oo ka hortagi karta miraha crystal-ka inay ku sii daraan crystals waaweyn. Tusaale ahaan, ilaa inta 0.4-0.6% microcrystalline cellulose lagu daro jalaatada, waa ku filan si looga hortago in badarka crystal barafka sii kordhaya inta lagu jiro baraf iyo dhalaalid joogto ah, iyo in la hubiyo in qaab-dhismeedka iyo qaab-dhismeedka aan isbeddelin, iyo microcrystalline. Qaybaha cellulose aad bay u fiican yihiin, waxay kordhin karaan dhadhanka. Ku darida 0.3%, 0.55%, iyo 0.80% microcrystalline cellulose ee jalaatada ay diyaarisay caanaha caadiga ah ee Britishka, viscosity ee kareemka jalaatada ayaa wax yar ka sarreeya taas iyada oo aan lagu darin microcrystalline cellulose, wax saameyn ahna kuma yeelan qadarka daadinta, iyo hagaajin karaa texture.
2.6 Microcrystalline cellulose ayaa sidoo kale loo isticmaalaa si loo yareeyo kalooriyeyaasha
Haddii loo isticmaalo dhaymada saladhka, yaree kalooriyooyinka oo kordhi cellulose si loo hagaajiyo guryaha la cuni karo. Marka la samaynayo xawaashyada kala duwan ee saliidda wax lagu kariyo, ku darida microcrystalline cellulose waxay ka ilaalin kartaa saliidda inay ka soocdo maraqa marka la kululeeyo ama la kariyo.
2.7 Kuwa kale
Sababo la xiriira adsorption ee cellulose microcrystalline, cuntooyinka leh macdanta sare leh waxaa laga heli karaa iyada oo la xayeysiinayo ee ion biraha.
