Microcrystalline Cellulose

Microcrystalline Cellulose(MCC) tsuas yog tsim ntawm linear polysaccharides Bonded los ntawm -1} {}} glucosidic bonds. Nws yog ib qho dawb, tsw ntxhiab, hmoov tsis muaj hmoov crystalline uas muaj peev xwm ntws tawm ntawm cov pa roj ntsha uas muaj cov roj ntsha tau los ntawm cov kua roj polymerization (lodp).
Nyob rau hauv cov nroj tsuag dav dav, microcrystalline cov nyiaj txiag rau kwv yees li 70%, thiab lwm 30% yog amorphous. Microcrystalline cellulose tau siv dav hauv cov tshuaj, kom hniav zoo nkauj, zaub mov thiab lwm yam kev lag luam. Qhov sib txawv sib txawv qhov ntau thiab tsawg cov dej thiab cov dej dej muaj cov yam ntxwv sib txawv thiab kev thov sib tw.

Qhov loj me me feem ntau yog 20 ~ 80μm, qhov kev txwv ntawm polymerization (lodp) yog 15 ~ 375, nws tsis yog-fibrous thiab muaj zog fluidity. Nws yog insoluble nyob rau hauv dej, dilute acid, organic kuab thiab muaj cov kev cuam tshuam loj hauv cov carboxymowylation, acetylation thiab cov txheej txheem Esterification. Vim nws cov khoom tshwj xeeb xws li tsawg dua cov polymerization thiab cov pob zeb loj, cov zaub mov, cov tshuaj pleev ib ce, tshuaj pleev ib yam thiab lwm yam tshuaj lom neeg.

Vim nws cov qauv tshwj xeeb thiab cov khoom, microcrystalline cellulose tau siv dav hlau, thiab kev noj qab haus huv, khoom noj thiab dej haus. Vim tias cellulose tau dav tam sim no nyob rau hauv qhov, ntau pua lab ntawm tons ntawm cov seem ntawm cellulass-nplua nuj yog tsim txhua xyoo hauv ntiaj teb. Yog tias cov kev nyob no tau hloov dua siab tshiab zoo thiab siv, lawv yuav yog cov khoom siv nplua nuj. Hauv Suav teb, nrog kev nthuav dav ntawm kev tsim khoom lag luam ntawm cov tawv, tshuaj, thiab cov khoom siv hauv microcrystalline muaj peev xwm ua rau muaj kev lag luam dav dav muaj kev lag luam dav. Microcrystalline cellulose tau suav nrog US FDA cov zaub mov kev nyab xeeb hauv Tebchaws Europe, muaj nyob hauv FDA cov khoom noj ntxiv ", thiab raug tso cai siv rau hauv kev npaj cov khoom xyaw tsis muaj nyob hauv UK.
Kws Tshuaj Kho Mob
Microcrotalline cellulose feem ntau yog siv los ua adsorbent, ncua sij hawm tus neeg saib xyuas, dag, thiab tsis muaj kev cais tawm. Microcrystalline cellulose tau siv dav hauv kev npaj tshuaj, feem ntau yog ua rau lub zog thiab phau ntawv qhia txog qhov ncauj thiab tsiav tshuaj. Nws tuaj yeem siv tsis tsuas yog rau cov granment ntub tab sis tseem rau cov ntsiav tshuaj ncaj qha compression. Nws tseem muaj cov nyhuv rau lubrication thiab cov nyhuv sib xyaw, uas yog qhov muaj txiaj ntsig zoo hauv cov ntsiav tshuaj npaj.
Vim tias muaj hydrogen khi nruab nrab ntawm cov me me cellulose lwg me me, yog li nws muaj qib siab ntawm kev nias siab thiab feem ntau siv los ua cov nplaum; Thaum cov ntsiav tshuaj nias tau ua kua, dej nrawm nkag cov ntsiav tshuaj uas muaj cov pob txha me me tau tawg tam sim ntawd, yog li nws tuaj yeem siv los ua kev ua tsis taus. Yog li ntawd, nws yog qhov siv dav dav siv rau hauv ntsiav tshuaj ntau lawm, uas tuaj yeem txhim kho lub hardness ntawm cov ntsiav tshuaj. Piv txwv li, hauv kev npaj ntawm RIFAMPICIN ntsiav tshuaj, microcrystalline cellulose tuaj yeem sib xyaw nrog 6.25: 1) thiab tom qab ntawd kaw ncaj qha rau hauv cov ntsiav tshuaj. Cov khoom disintegrates rau hauv yexus tsis pub dhau 1 feeb. Ntxiv mus, cov ntsiab lus tseem unchanged thaum lub sijhawm siv tau, thiab cov tshuaj ruaj khov tuaj yeem txhim kho zoo heev. Piv txwv li, vim ntxiv ntawm cov microcrystalline cellulose, cov solubility ntawm prednisone acetate (berberine hydrochloride) ntsiav tshuaj ntxiv rau ntau dua 80%. Thaum siv microcrystalline cellulose raws li kev zam rau cov ntsiav tshuaj, cov txheej txheem granulation tso cai tsis tas yuav. Piv txwv li, nyob rau hauv kev npaj ntawm keiqing ntsiav tshuaj, vim qhov sib ntxiv ntawm cov kab ke me me los ntawm kev ua kom yooj yim ntawm cov ntsiav tshuaj ntub dej yog daws, thiab kev ua kom tawg tau nrawm.
Microcrosealline cellulose kuj tseem siv tau ua tus neeg saib xyuas kom tso tawm rau cov tshuaj. Cov txheej txheem tso tawm-tso tawm yog tias cov tshuaj nquag nkag mus rau hauv cov qauv ua qauv ntawm cov cab kuj. Cov tshuaj nquag muaj nyob ntawm cov khoom siv hydrogen hydrogen hydrogen thiab yog tsau tom qab ziab. Thaum cov khoom siv nquag tso tawm, cov dej ua kom diffuses hauv cov capillary ntawm cov cab kuj uas muaj kev phom thiab cov khoom siv hluav taws xob tau raug tshem tawm.
Microcrystalline cov hmoov cellulose hmoov tuaj yeem tsim cov txheej txheem ruaj khov hauv dej. Nws tuaj yeem ua ke nrog cov tshuaj los ua creamy lossis tshem tawm cov tshuaj ua kom qhuav, thiab tseem siv tau raws li cov tsiav tshuaj. Microcrystallose cellulose cov qauv gels nyob rau hauv dej tom qab muaj zog nplawm, thiab tseem siv tau los ua cov tshuaj ntxuav thiab tshem tawm hom kev npaj tshuaj.
Kev Lag Luam Khoom Noj
Hauv kev lag luam khoom noj khoom haus, microcrystalline cellulose, raws li hom kev noj qab haus huv thiab ua npuas dej zoo, tswj tau qhov muaj qhov ruaj khov, thiab txhim kho qhov ruaj khov ntawm cov kua. Nws tau muaj ntawv pov thawj thiab pom zoo los ntawm kev ntsuas pawg neeg ntawm cov zaub mov ntxiv ntawm cov khoom noj khoom haus thiab ua liaj ua teb hauv Tebchaws Meskas thiab lub koom haum hauv ntiaj teb. Corresponding fiber products have also appeared and are widely used in dairy products, frozen foods, meat products, etc.
3 Tshuaj pleev ib ce
Microcrystalline cellulose tuaj yeem siv los ua cov khoom xyaw hauv kev tsim cov tshuaj pleev ib ce, tawv nqaij tu, thiab tu cov tshuaj kho mob.

(1) Qhov loj tshaj plaws application feature ntawm microcrystalline cellulose hauv kev npaj khoom yog nws cov kev ntsuas siab. Piv nrog rau lwm yam khoom siv tshuaj tiv thaiv, qhov no yog vim muaj hydrogen bonds ntawm cov me me cellulose molecules. Thaum compressed, cov hydrogen bonds tau sib xyaw ua ke, yog li nws muaj qib siab ntawm kev nias siab thiab tuaj yeem nce lub hardness ntawm cov ntsiav tshuaj. Yog li ntawd, nws feem ntau siv los ua cov nplaum qhuav; Nyob rau tib lub sijhawm, thaum lub ntsiav tshuaj compressed sib ntsib kua, dej nrawm tau nkag rau sab hauv ntawm cellulose tau tawg, yog li nws kuj tseem siv tau ua ib qho kev tsis sib luag. Yog li ntawd, nws yog siv dav hauv cov ntsiav tshuaj ntau lawm.

(2) Microcrystalline cellulose muaj peev xwm nqus dej siab. Ntawm ib sab tes, tus xeeb ceem no muaj qhov zoo slurry nqus tau thaum siv cov nplaum uas muaj peev xwm ntxiv rau cov nplaum, ua rau cov haujlwm ua haujlwm tau ntxiv. Ntawm qhov tod tes, zoo wettability tuaj yeem nce cov txheej txheem ntub dej ntawm cov khoom siv thaum lub ntsej muag ntub thiab kev sib txawv ntawm cov khoom siv ua tiav cov khoom lag luam. Thib peb, cov dej nqus dej siab ntawm microcrystalline ua rau muaj kev hygroscopicity muaj zog ntawm kev npaj. Qhov hnyav nce ntawm cov ntshiab microcrystalline ntawm RH75% rau 5 xyoos ntau dua 5%, thiab qhov hnyav nce tshaj 10% ntawm RH92.5% rau 5 hnub. Yog li ntawd, thaum cov feem ntawm cov nyiaj ob sab ntawm cov tshuaj yog qhov siab, saib xyuas yuav tsum tau them rau qhov teeb meem ntawm hygroscopic stability. , nyob rau hauv ib txwm ib txwm muaj tej yam kev mob, noo noo cov ntsiab lus ntawm microcrystalline feem ntau nyob ib ncig ntawm 3% ~ 5%, thiab nws yog qhov ruaj khov;

(3) Lub zog thib ob ntawm cov pwm hluav taws xob ntawm cov microcrystalline yog neeg pluag, thaum lactose kuj zoo rau lub sijhawm no;

(4) Vim tias microcrystalline yog insoluble hauv dej, yog ib lub khob hauv qab, uas yog, microcutions khaws cia tom qab kev sib cais, uas ua rau tsis tiav ntawm API. Yog li ntawd, rau cov tshuaj tsis zoo, cov microcrystalline dav dav tau pom zoo kom tsis txhob tshaj 30%. Yog tias txoj hauv qab tawm hauv qab tshwm sim, microcrystalline piv tau tuaj yeem txo, lossis nrawm dua ({2}} rpm)

(5) Hauv ntau hom ntawm cov microcrystalline cellulose tshuab, sib npaug sib npaug yog: qhov zoo dua cov fluidity, qis dua cov pwm.

Pom nyob rau hauv 2014, ytbio tsuas yog cov khoom noj ntxiv rau cov khoom noj ntxiv xws liMicrocrystalline Cellulose, Herbal rho tawm, ua haujlwm kom hniav zoo nkauj roj nyoos, cov khoom siv organic, thiab lwm yam ntawm peb tus kheej. Tam sim no, peb cov ntawv pov thawj suav nrog ISO9001, ISO22000, KOSHER, HACCP, thiab lwm yam khoom siv tau thiab peb txhawb nqa cov kev xeem thib peb. Peb muab ntau yam khoom lag luam, rau cov ntaub ntawv ntxaws ntxaws txog cov khoom, thov nyem {{{} Hu rau peb, peb yuav muaj cov neeg muag khoom muag kom muab cov lus teb kom ntxaws
