Carboxymetylcelleculose (CMC) thiab xanthan ntawm cov pos hniav yog ob qho tib si hauv cov khoom noj khoom haus uas muaj cov khoom noj ua ke, stabilizers, thiab gelling cov neeg sawv cev. Txawm hais tias lawv qhia qee qhov kev ua tau zoo, ob yam tshuaj muaj ntau txawv dua hauv keeb kwm, qauv, thiab kev siv.
Carboxymethylcellulose (CMC):
1. Tau qhov chaw thiab qauv:
Tau qhov twg los: CMC tau muab los ntawm cellulose, lub ntuj polymer pom hauv tsob ntoo cell phab ntsa. Nws yog feem ntau muab rho tawm los ntawm ntoo pulp lossis cov paj rwb fibers.
Tus qauv: CMC yog lub cellulose derivative ua los ntawm carboxymethylation ntawm cellulose molecules. Carboxymethylation cuam tshuam nrog kev qhia ntawm Carboxymethyl pab pawg (-ch2-npo rau hauv cov qauv cellulose.
2. Solubility:
CMC yog soluble hauv dej, sib sau ua kom pom tseeb thiab muaj kuab. Cov qib degree hloov pauv (DS) hauv CMC cuam tshuam rau nws cov solubility thiab lwm yam khoom.
3. Muaj nuj nqi:
Thickening: CMC tau siv dav siv ua tus neeg sawv cev tuab ntawm ntau yam khoom noj khoom haus, suav nrog cov kua ntses, hnav khaub ncaws, hnav thiab cov khoom noj siv mis.
Kev ruaj khov: nws yuav pab ruaj khov kho thiab raug ncua, tiv thaiv kev sib cais ntawm cov khoom xyaw.
Dej khaws cia: CMC yog paub rau nws lub peev xwm los khaws dej, pab khaws cia noo noo hauv cov zaub mov.
4. Daim ntawv thov:
CMC feem ntau siv hauv kev lag luam khoom noj khoom haus, cov chaw muag tshuaj thiab tshuaj pleev ib ce. Nyob rau hauv kev lag luam khoom noj khoom haus, nws yog siv nyob rau hauv cov khoom xws li mis nyuj khov, dej haus thiab ci khoom.
5. Kev Txwv:
Txawm hais tias CMC tau siv dav, nws cov txiaj ntsig yuav cuam tshuam los ntawm yam xws li pH thiab muaj qee yam ntawm ions. Nws tuaj yeem qhia txog kev ua tsis zoo nyob hauv cov acidic.
Xanthan ntawm cov pos hniav:
1. Tau qhov chaw thiab qauv:
Tau qhov twg los: Xanthan ntawm cov pos hniav yog cov polysaccharide tsim los ntawm fermentation ntawm carbohydrates los ntawm tus kab mob canthomonas conteesris.
Tus qauv: Cov qauv theem pib ntawm Xanthan ntawm cov pos hniav muaj ntawm lub cellulose caj qaum nrog trisaccharide sab saw. Nws muaj cov piam thaj, mannose thiab kua qaub ua kua roj hmab.
2. Solubility:
Xanthan ntawm cov pos hniav yog soluble heev hauv dej, sib sau ua cov tshuaj uas khov ntawm cov kev ua kom muaj ntau.
3. Muaj nuj nqi:
Thickening: zoo li CMC, Xanthan ntawm cov pos hniav yog ib tus neeg sawv cev tuab tuab. Nws muab cov zaub mov kom du thiab elastic.
STABILITY: Xanthan ntawm cov pos hniav ua kom raug ncua thiab emulsions, tiv thaiv theem sib cais.
Gelling: Hauv qee cov ntawv thov, xanthan ntawm cov pos hniav hauv gel tsim.
4. Daim ntawv thov:
Xanthan ntawm cov pos hniav muaj ntau yam ntawm kev siv hauv kev lag luam khoom noj khoom haus, tshwj xeeb hauv gluten-dawb khaub ncaws, nyias noj hnav thiab kua qab. Nws tseem siv nyob rau hauv ntau cov ntawv thov.
5. Kev Txwv:
Hauv qee cov kev siv, siv xanthhan ntawm cov pos hniav yuav ua rau muaj cov nplaum lossis "kev ua haujlwm" los ntswg ". Ua tib zoo tswj tau cov koob tshuaj yuav tsum tau kom tsis txhob muaj cov khoom uas tsis muaj kev xav tau.
Piv:
1. Source:
CMC yog muab tau los ntawm cellulose, cov nroj tsuag-raws polymer.
Xanthan ntawm cov pos hniav yog tsim los ntawm microbial fermentation.
2. Dememical qauv:
CMC yog lub cellulose derivative ua los ntawm Carboxymethylation.
Xanthan ntawm cov pos hniav muaj cov qauv nyuaj dua nrog cov saw trisaccharide.
3. Solubility:
Ob CMC thiab xanthan ntawm cov pos hniav yog dej-soluble.
4. Muaj nuj nqi:
Ob leeg ua raws li cov tuab tuab thiab cov stabilizers, tab sis tej zaum yuav muaj kev cuam tshuam me ntsis ntawm kev ntxhib los mos.
5. Thov:
CMC thiab xanthan ntawm cov pos hniav yog siv nyob rau ntau yam khoom noj thiab kev siv khoom noj, tab sis kev xaiv ntawm lawv yuav nyob ntawm cov kev xav tau ntawm cov khoom.
6. Kev Txwv:
Txhua tus muaj nws cov kev txwv, thiab kev xaiv ntawm lawv yuav nyob ntawm cov khoom siv xws li pH, noj tshuaj, thiab xav tau kev ntxhib los mos ntawm cov khoom kawg.
Txawm hais tias cmc thiab xanthan ntawm cov pos hniav muaj cov kev siv cov khoom siv hydrocolloids hauv kev lag luam khoom noj, lawv txawv hauv keeb kwm, qauv, thiab ntawv thov. Qhov kev xaiv ntawm CMC thiab Xanthan ntawm cov pos hniav nyob ntawm cov kev xav tau tshwj xeeb ntawm cov khoom lag luam, noj mus rau hauv tus account cov ntsiab lus xws li PH, kev tshuaj thiab xav tau cov khoom siv textage. Ob qho tshuaj yeeb pab txhawb cov kev ntxhib los mos, ruaj khov thiab tag nrho cov khoom noj thiab cov khoom lag luam muaj ntau yam.
