Hauv kev lag luam khoom noj niaj hnub, sodium cmc (carboxymethyl cellulose) tau siv dav hauv ntau cov dej haus ua cov zaub mov tseem ceeb ntxiv. Tshwj xeeb tshaj yog nyob rau hauv acidic dej, siab} 2}} CMC tau dhau los ua ntau cov khoom lag luam hauv dej vim nws ruaj khov thiab lub cev zoo. Tom ntej no, peb yuav nthuav dav tham ntawm cov txheej txheem kev tshwj xeeb uas yog cov khoom siv acidity los ntawm ntau qhov ntev ntawm cov acid {} {tus neeg tsis muaj kev sib tw ntawm cov khoom thiab colloids.
1. Kev ruaj khov ntawm cov kua qaub -} tsis kam qauv
Acid - ive resist los ntawm cov txheej txheem tshwj xeeb muaj cov txheej txheem molecethyl ib feem ntau cov khoom noj qab zib) feem ntau yog tswj hwm ntawm 0.8 thiab 1.2. Cov qauv no ua rau CMC tsawg tshaj plaws rau kev tawm tsam cov kev cuam tshuam nrog qee yam kev ua tau zoo, thaum muaj cov roj ntsha cellulos (} Cellule
Txawm nyob rau hauv ib puag ncig pH tsawg, nws tuaj yeem tswj hwm kev sib txuas lus ruaj khov los ntawm kev sib tw hydrogen hydrogen hydrogen bashlen cov nyhuv tuab. Cov ntaub ntawv sim qhia tau tias siab - tsis muaj hom viscosity ntau dua li 50% nyob rau hauv cov qauv viscosity). Hla - txuas ntawm cellulose cell molecular charmacts, uas khov kho cov roj hauv cov network, txuas ntxiv txhim kho qhov ruaj ntseg ntawm lub system. Nws tuaj yeem tswj cov kev sib cais ntawm kev sib cais, txawm tias raug ua kom nruj kev tsiv los yog kub hloov pauv.
Hauv cov dej haus, tshwj xeeb yog cov kua txiv, tshuaj yej dej haus thiab qee cov dej haus tuaj yeem ua rau muaj kev viscosity, cmcs ua tau zoo nce lub viscosity ntawm cov kua, ua kom cov dej haus muaj cov ntsej muag thiab cov khoom noj muaj zog. Piv nrog tsoos thickeners tsoos, acid - Resestant CMC tuaj yeem ruaj khov ntawm tus nqi hauv qab qis thiab yuav tsis ua daus lossis nag lossis daus.
Ntxiv rau, kua qaub - iveSive CMC nrog High DS tuaj yeem tiv thaiv kev sib cais ntawm cov kua thiab txhim kho tag nrho kev ruaj ntseg ntawm cov dej haus. Qhov no yog qhov tshwj xeeb tshaj yog rau cov kua qaub ua kua qaub thiab kua txiv kab ntxwv. Nws tuaj yeem ua kom pom qhov zoo thiab saj ntawm cov dej haus, muaj txuas ntxiv lub txee lub neej ntawm cov khoom.
2. Ncua thiab cov stabilization ntawm cov lus thiab colloids
Hauv qee qhov kev haus dej haus (xws li cov pob zeb, smoothies,} Nws pab kom tswj cov kev sib tw ntawm cov khaub ncaws, ua cov khoom lag luam ruaj khov thiab muag heev.
Cov dej haus acidic feem ntau muaj cov khoom xyaw ua ke xws li cov kua txiv ntoo ua kom muaj txiaj ntsig zoo, uas yog qhov yooj yim rau kev ua kom tsis txaus siab vim tias qhov tsis txaus ntseeg nyob rau hauv acidic tej yam kev mob. Sodium CMC ua tiav kev ruaj khov los ntawm ob lub tshuab:
Story fonder nyhav: beverage qib qib cmab molcular yog adsorbed ntawm txog li 5-10n, uas thaiv kev sib cuag ncaj qha thiab kev sib sau ntawm cov khoom;
Cov tshuaj tsis zoo: Txawm hais tias tus nqi tsis zoo ntawm CMC txo qis hauv cov acidic ib puag ncig, nws tseem tuaj yeem muab cov khoom siv hluav taws xob tsis muaj zog, uas koom tes nrog cov ntawv sib tsoo kom muaj kev cuam tshuam nrog inhibit sedimentation.
Noj ib co txiv hmab txiv ntoo dej haus kua txiv ua piv txwv, tom qab ntxiv 0.% -80%, thiab cov uniform kev tshem tawm lub xeev tuaj yeem raug tswj tau thaum lub sijhawm 3-lub sijhawm.
3. Kev cai ntawm lub cev rheological cov khoom
Qhov saj ntawm cov kua qaub yog ze ze rau cov viscosity ntawm lub system. Tsawg dhau viscosity tsawg yuav coj ib daim nyias nyias, thaum viscosity siab dhau yuav ua kom nws nplaum. Cellulose Cellul tuaj yeem tswj hwm lub rheological tsis ntawm lub system los ntawm kev kho cov molecular chart thiab concentration:
Hauv cov dej ntws tawm acidic, ntxiv 0.1%- 0.}} palcosable cmc tuaj yeem ua rau kev khiav tawm ntawm npuas;
Nyob rau hauv tsis - {}-}}}}}}}}} 0. Txawj me me} 0. looj ntsej muag rau cov tshuaj acidritation los ntawm acidic tshuaj.
Cov kev cai rheological kev muaj peev xwm ua rau cov zaub mov no siv CLC ua ib qho kev ua kom zoo dua ntawm cov kua qaub, uas tuaj yeem ua rau qhov tsw tau, uas tuaj yeem ua rau cov tsw los ntawm kev ua kom pom tseeb.
Hauv cov ntsiab lus xaus, Los ntawm ntau cov txheej txheem xws li cov txheej txheem ruaj khov, kev tiv thaiv zoo, ua rau muaj kev lag luam hauv qab tsis muaj txiaj ntsig ntxiv hauv kev lag luam ntawm cov nqaij acidic dej.
