Nrog kev loj hlob tseem ceeb rau kev noj zaub mov zoo, siab - Cov khoom lag luam protein zoo tshaj plaws hauv kev ua lag luam. Los ntawm mis nyuj thiab taum pauv rau ntau tsob nroj-}}}} Cov khoom noj muaj txiaj ntsig thiab maj mam muab cov protein thiab maj mam muab cov protein nyob hauv yog qhov teeb meem tseem ceeb ntsib kev lag luam khoom noj. Ntawm cov thev naus laus zis ntau, membrane sib cais tshuab sawv nrog nws cov cim tshwj xeeb. Tshwj xeeb,Ultrafiltration hauv kev lag luam khoom noj khoom hausYog tshwj xeeb tshaj plaws tsis tau txais kev hloov pauv hloov pauv rau cov protein niaj hnub.
► I. Ua rau ua haujlwm thiab cov tswv yim zoo
Txhawm rau nkag siab ultraroftration thev naus laus zis, ib qho tuaj yeem xav txog nws li qhov tseeb heev "cov suab nrov molecular." Ntawm nws cov tub ntxhais yog daim nyias nyias nyias muaj nyias qhov hws sib xyaw. Tsav los ntawm ib qho siab, cov tshuaj me me hauv cov kua nyeem, xws li cov ntsev tsis zoo, thiab cov khoom loj} molecule cov tshuaj zoo li cov protein yog tau tuav tseg.
Qhov zoo tshaj plaws ntawm cov txheej txheem no dag nyob rau hauv nws "maj mam" xwm. Tsis zoo li cov txheej txheem ib txwm zoo li thermal concuster lossis tshuaj nag lossis kub tau ua tiav thiab tsis tas yuav muaj qhov ntau ntawm cov tshuaj ntxuav kom loj. Qhov no txhais tau tias cov qauv ntuj thiab kev ua si ntawm cov protein tuaj yeem raug tshwj tseg rau cov khoom lag luam protein (xws li whey protein, immunoglobs, thiab lwm yam).
► II. Cov Ntawv Qhia Tshwj Xeeb
Daim ntawv thov ntawm ultraFiltration technology hauv kev ua protein ntau thiab tuaj yeem qhia tshwj xeeb hauv cov hauv qab no:
1. Cov protein concentration thiab purification
Nyob rau hauv ntau cov txheej txheem ua zaub mov noj, thawj cov tshuaj muaj protein muaj qhov muaj txiaj ntsig, xws li cov whey whey tom qab ntau lawm. Ncaj qha kom qhuav qhov kev daws teeb meem no tsis yog lub zog tsis yog xwb Los ntawm kev siv ultrafiltration membrane system, dej thiab me me - molecule imagrenation, ua tiav cov txiaj ntsig sai sai rau cov txheej txheem txuas ntxiv xws li cov tshuaj tsuag. Nyob rau tib lub sijhawm, cov txheej txheem no tseem tau tshem cov pigments, tawm {{5} Txhim kho qhov zoo thiab tsw ntawm cov khoom kawg.
2. Kev sib cais zoo raws li cov khoom
Lub ntiaj teb ntawm cov protein tsis yog "ib - loj {} fits - txhua yam." Txawm tias cov protein nrog cov hnyav hnyav yuav muaj cov khoom sib txawv ntawm lub cev. Protein molecules Nqa cov hluav taws xob ntxiv, thiab lawv tus nqi them lub xeev kev hloov pauv nrog ph ntawm ib puag ncig ib puag ncig. Los ntawm kev siv cov xeeb ceem no thiab precisely tswj cov ph thiab ionic lub zog ntawm cov tshuaj muaj sib txawv, yog li cuam tshuam lawv cov kev cuam tshuam nrog ultrafiltration membrane. Qhov no ua rau nws ua tiav kom tau kev sib cais zoo ntawm cov protein nrog cov khoom siv hluav taws xob zoo ib yam li cov khoom siv ultrafiltration siv cov khoom siv ultrafiltration los ntawm ntau cov haujlwm sib cais, txhim kho kev sib cais zoo heev.
3. Cov peev txheej rov qab thiab kev tiv thaiv ib puag ncig
Yav dhau los, ntau cov zaub mov ua kom zoo nkauj muaj cov protein (xws li taum protein ntau lawm, uas tsis yog cov khoom siv muaj txiaj ntsig tsuas yog siv sijhawm rau ib puag ncig. Niaj hnub no, ultrafiltration hauv kev lag luam khoom noj khoom haus muaj qhov kev daws teeb meem zoo tshaj plaws rau cov teeb meem no. Los ntawm ultrafiltration technology, residual protein nyob rau hauv dej khib nyiab tuaj yeem zoo tu qab, tig cov khib nyiab mus rau cov khoom muaj nqis thiab tsim muaj txiaj ntsig nyiaj txiag ntxiv. Lub caij no, lub purutsht concentration nyob rau hauv kho cov tshuaj tua dej tau zoo heev, ua raws li kev sib koom ua ke ntawm kev ua haujlwm ntawm kev lag luam thiab cov txiaj ntsig ib puag ncig.
►i. Txheej Txheem Flow thiab Khoom Siv Kev Txiav Txim Siab
Cov txheej txheem ua tiav ultrafiltration cov txheej txheem feem ntau suav nrog peb theem: Detreatment, Kev Pom Kev Tseem Ceeb, thiab Kev Kho Mob} Kev Kho Mob. Pretreatment lub hom phiaj kom tshem tawm cov khib nyiab tshem tawm thiab cov khoom tsis txaus siab los ntawm kev ua kom ultrafiltration membrane los ntawm kev puas tsuaj rau lub cev. Cov ntsiab lus tseem ceeb ntawm cov cuab yeej ua tiav hauv cov khoom siv ultrafiltration, uas tus ntoo khaub lig} txaus lim tawm cov molecules tsis tu ncua thiab concentrates cov protein me. Tsis pub dhau tag nrho cov txheej txheem ntau lawm, dej ultrafiltration thev naus laus zis kuj tseem siv lub luag haujlwm ntawm cov dej tseem ceeb, ua kom huv si.
Nws yog tsim nyog teev uas kom ntseeg tau ntev {}}}}}}}}}}}} tu ua haujlwm ntawm ultrafiltration system, membrane ntxuav thiab kev txij nkawm yog qhov tseem ceeb. Membrane fouling yog qhov kev sib tw tsis tau zam, uas yuav tsum muaj kev sib tw ntawm lub cev thiab tshuaj ntxuav kom huv. Hauv kev ntxuav thiab hloov chaw ua haujlwm, qhov xav tau rau cov dej tsis zoo yog qhov siab heev, feem ntau tsim nyog siv cov khoom siv xws liEDI DEJ KHO MOBTxhawm rau npaj siab -}}}}} Kev pham kev ua kom zoo, ua kom muaj txiaj ntsig ntawm kev ntxuav thiab kom tsis txhob muaj kev paug ob.
► IV. Cov kev sib tw thiab yav tom ntej saib xyuas
Txawm hais tias qhov zoo ntawm ultrafiltration thev naus laus zis yog qhov teeb meem ntawm Membrane fouling tseem yog qhov kev sib tw loj hauv nws cov ntawv thov, uas cuam tshuam rau kev ua haujlwm thiab kev ua kom muaj sia. Yog li ntawd, txoj kev txhim kho yav tom ntej yuav tsom rau kev tsim cov ntaub ntawv tshiab ntawm cov ntaub ntawv tshiab nrog cov tshuaj tiv thaiv muaj zog thiab muaj peev xwm flux
Hauv cov ntsiab lus xaus, ultrafiltration hauv kev lag luam khoom noj khoom haus tau dhau los ua ib qho ntawm cov tseem ceeb thev naus laus zis tsav cov khoom hloov pauv ntawm cov khoom protein ntau. Nws tsis tsuas yog txhim kho kev ua haujlwm tau zoo thiab cov khoom zoo tab sis kuj ua kom haum rau lub sijhawm ntawm cov khoom ntsuab thiab kev txhim kho kom ruaj khov. Nws yog qhov xav tau uas yog cov thev naus laus zis txuas ntxiv kom paub tab ntawm kev lag luam khoom noj yuav tob dua thiab muaj txiaj ntsig zoo protein rau cov neeg siv khoom.
