Mis, whey thiab khoom noj siv mis

Feem ntau siv cov txheej txheem ceramic membrane kom cais cov Concentrated milk proteins (MPC) thiab cais cov mis proteins (MPI) los ntawm cov mis nyuj tshiab.nyob zoo muaj nplua nuj nyob rau hauv casein thiab whey protein, muab cov nplua nuj calcium nrog zoo thermal stability thiab refreshing qhov ncauj.

Mis protein concentrates yog siv dav thiab zoo tagnrho rau cov khoom siv cheese, cov khoom siv dag zog, cov khoom siv mis nyuj, khoom noj rau menyuam mos, khoom noj khoom haus, khoom noj khoom haus, cov khoom noj khoom haus, cov khoom noj khoom haus thiab cov khoom noj khoom haus.

Feem ntau, cov mis nyuj protein concentrates muab cov ntsiab lus ntawm cov protein ntau rau kev hnov ​​​​lus thiab kev ua haujlwm hauv cov txheej txheem kev thov zaum kawg kom tau raws li cov khoom noj muaj txiaj ntsig.Condensed mis nyuj protein ua lwm yam rau tag nrho cov mis nyuj hmoov (WMP), skim mis nyuj hmoov (SMP) thiab lwm yam mis nyuj hmoov, muab tib cov protein, los yog raws li ib tug tsis muaj rog mis nyuj khov (MSNF).Piv nrog rau cov mis nyuj zoo tib yam lossis skim mis hmoov, cov kua mis muaj protein ntau nrog cov protein ntau, cov yam ntxwv tsis muaj lactose.

Cov txheej txheem ultra-siab kub ua kom tsis muaj menyuam yuav rhuav tshem ntau cov khoom noj muaj txiaj ntsig hauv cov mis nyuj tab sis qis-kub ceramic membrane filtration thev naus laus zis tag nrho cuam tshuam cov tsoos kub kub kom tsis muaj menyuam.Cov txheej txheem ntawm cov kua mis pom thiab qhia meej yog ua kom cov kua mis nyuj tshiab los ntawm cov khoom siv mis nyuj ceramic membrane thiab tsis txhob muaj cua sov denaturation ntawm cov protein.

Kev tshem tawm cov kab mob
Zoo li ntau yam khoom noj, mis nyuj thiab nws cov derivatives muab ib qho chaw tsim nyog rau cov kab mob spoilage.Yog li ntawd, pretreatment thiab kub, lub sij hawm tsis yuav tsum tau xaiv los tswj kev loj hlob ntawm cov kab mob.Kev kho cua sov thiab centrifugal sterilization yog cov txheej txheem ib txwm siv los txo tag nrho cov kab mob hauv cov mis nyuj thiab cov khoom siv mis nyuj, tab sis cov qauv no muaj lawv tus kheej qhov zoo thiab qhov tsis zoo.Cov txheej txheem ib txwm siv los tshem tawm cov kab mob hauv cov mis nyuj muaj ntau cov kauj ruam thiab tus nqi siab, lub neej luv luv, kev ua qias tuaj ib puag ncig, kev tu tsis yooj yim.Txawm li cas los xij, cov kua nplaum nplaum nplaum ntawm cov mis nyuj tuaj yeem daws tau cov teeb meem no.

Membrane sib cais tshuab yog siv los tshem tawm cov kab mob hauv cov mis nyuj, uas yog raws li qhov tseeb tias daim nyias nyias muaj qhov sib txawv ntawm cov khoom khaws cia hauv ntau yam ntawm cov mis nyuj, suav nrog cov kab mob thiab cov spores.Cov kab mob tuaj yeem ua rau qhov tsis lees paub ntau dua 99%, thaum casein transmittance tuaj yeem ncav cuag li 99%.

Membrane sib cais tshuab muaj qhov zoo ntawm daim nyias nyias thiab ua kom tsis muaj menyuam, tuaj yeem tshem tawm cov kab mob hauv cov kua mis, tib lub sijhawm cov kua mis kuj tau txhim kho.

Membrane sib cais tshuab rau txias kom tsis muaj menyuam yog cov qauv ntawm cov mis nyuj tshiab yog preheated txog 50 degrees thiab skim mis nyuj yog tau los ntawm mis nyuj sib cais tshuab.Tom qab ntawd nyob rau tib hnub cov mis nyuj tshiab ua kom tsis muaj menyuam, ua ke nrog cov tshuab ua kom tsis muaj menyuam kub sai sai, kom nkag tau rau cov khoom noj siv mis zoo.Xws li qhov ntsuas kub qis kom tsis muaj menyuam khaws cov tsw zoo thiab cov as-ham, nplua nuj aroma.

Tsis tas li ntawd, kev tu daim nyias nyias yog yooj yim dua rau rov tsim dua tshiab, yog li cov membrane fouling tuaj yeem tswj tau thiab khaws cia ntau dua thiab ruaj khov membrane flux.Kev siv cov txheej txheem sib cais membrane rau kev ua kom tsis muaj menyuam txias, cov khoom siv ua haujlwm tuaj yeem khaws cia thaum lub sijhawm rov sib cais, yog ib txoj hauv kev zoo tshaj plaws ntawm kev ua kom tsis muaj menyuam.

Kev tshem tawm cov kab mob Whey Caseim
Casein yog qhov tseem ceeb ntawm cov cheese zoo tib yam.Hauv cov txheej txheem ua cheese, casein yog precipitated los ntawm kev ua ntawm rennet enzymes, thiab ib coagulum yog tsim muaj xws li casein, whey proteins, rog, lactose thiab minerals ntawm cov mis nyuj.

Membrane sib cais tshuab yog siv los tshem tawm cov kab mob hauv cov mis nyuj, uas yog raws li qhov tseeb tias daim nyias nyias muaj cov khoom sib txawv ntawm cov khoom sib txawv ntawm cov mis nyuj, suav nrog cov kab mob thiab cov kab mob spores.Bacteria tuaj yeem ua rau qhov tsis lees paub ntau dua 99%, thaum casein. transmittance tuaj yeem ncav cuag li 99%.
