Khoom Noj Khoom Noj Qib Sodium Carboxymethyl cellulose (CMC) yog ib qho muaj txiaj ntsig ntxiv rau nws cov khoom noj muaj ntau yam thiab ntau yam kev siv hauv kev lag luam khoom noj. CMC yog muab tau los ntawm cellulose, lub ntuj polymer pom nyob rau hauv tsob nroj cell phab ntsa, thiab undergoes ib series ntawm cov solubility thiab ua haujlwm.
Cov yam ntxwv ntawm cov zaub mov Qib Sodium Carboxymethyl cellulose:
Solubility: Ib qho ntawm cov khoom noj uas tsis muaj txiaj ntsig ntawm cov zaub mov Qib CMC yog nws cov kev ua siab loj hauv ob qho dej txias thiab dej kub. Cov cuab yeej no ua rau nws yooj yim mus rau ntau yam khoom noj thiab dej haus cov khoom lag luam.
Viscosity: cmc yog muaj nuj nqis rau nws lub peev xwm los hloov viscosity ntawm kev daws teeb meem. Nws ua raws li tus neeg saib xyuas tuab, muab cov ntawv siv thiab ua tau zoo ib yam rau cov kua zaub, xws li cov kua ntses, hnav khaub ncaws, thiab khoom siv mis.
Stability: Cov zaub mov-qib CMC txhim kho kev ruaj khov, tiv thaiv theem sib cais thiab nce txee lub neej. Qhov no ua rau nws yog qhov tseem ceeb hauv ntau cov zaub mov ua tiav.
Zaj duab xis-ua cov khoom: CMC tuaj yeem tsim cov yeeb yaj kiab nyias nyias, uas yog muaj txiaj ntsig hauv cov ntawv thov tiv thaiv nyias. Cov cuab yeej no yog siv hauv cov khaub noom txheej thiab ua cov txheej txheem thaiv hauv qee cov khoom ntim khoom.
Pseudopastic: lub rheological coj cwj pwm ntawm CMC feem ntau pseudopastic, lub ntsiab lus uas nws viscosity txo qis nyob rau hauv shear kev ntxhov siab. Cov cuab yeej no yog qhov zoo hauv cov txheej txheem xws li twj thiab dispensing.
Compatibility nrog lwm cov khoom xyaw: CMC tau tshaj tawm ntau yam ntawm cov khoom xyaw uas tau siv ntau siv hauv kev lag luam khoom noj. Qhov kev sib raug zoo no txhawb rau nws cov versatility thiab ntau siv siv.
Cov Txheej Txheem Ntau Lawm:
Kev tsim khoom noj khoom noj-qib CMC cuam tshuam ntau cov kauj ruam los hloov cellulose, lub ntsiab tivthaiv ntawm cov nroj tsuag phab ntsa. Cov txheej txheem feem ntau suav nrog:
Kev Kho Mob Alkali: kho cellulose nrog cov alkali (feem ntau sodium hydroxide) los ua alkali cellulose.
Eetherification: alkaline cellulose rov qab nrog molochloroacetic acid los qhia carboxymethyl pawg ntawm lub cellulose lub cellulose lub cellulose tseem ceeb txoj saw hlau. Kauj ruam no yog qhov tseem ceeb kom ua kom cov dej solubility ntawm cov khoom kawg.
Neutralization: Nruab nruab nrab cov tshuaj tiv thaiv cov khoom kom tau cov ntsev ntsev ntsev ntawm Carboxymelylulose.
Purification: Cov khoom lag luam nyoos Undergoes Ib qho kev ua kom muaj zog los ua kom pom tseeb tias qhov kawg CMC cov khoom tau ua tiav cov khoom noj qib lus.
Cov ntawv thov hauv kev lag luam khoom noj:
Khoom Noj Khoom Haus CLC muaj ntau cov ntawv thov hauv kev lag luam khoom noj khoom haus, pab txhim kho qhov zoo thiab ua haujlwm ntawm ntau yam khoom. Qee cov ntawv thov sau cia muaj xws li:
Cov khoom ci: cmc yog siv nyob rau hauv cov khoom ci xws li qhob cij, ncuav thiab ncuav qab zib los txhim kho cov khob noom cookie cog qoob loo thiab ua kom dej tshiab.
Cov khoom noj siv mis: hauv cov khoom noj mis nyuj xws li mis nyuj khov thiab yogurt, cmc ua raws li lub stabilizer, tiv thaiv cov muaju dej khov los ntawm kev sib sau thiab tswj kev ntxhib los mos.
Cov kua nplaum thiab hnav khaub ncaws: CMC ua raws li tus neeg sawv cev ua kom tuab ntawm cov kua thiab hnav khaub ncaws, ua kom muaj txiaj ntsig zoo thiab ua kom zoo dua qub.
Haus: Siv rau hauv dej haus kom tswj tau kev raug tshem tawm, tiv thaiv kev ua kom tiav thiab txhim kho saj.
Confectionery: CMC yog siv nyob rau hauv kev tsim khoom ntawm confectionery los muab cov khoom siv ua yeeb yaj kiab rau txheej thiab tiv thaiv cov piam thaj crystallization.
Cov nqaij nqaij ua tiav: hauv cov nqaij nqaij ua tiav, cmc pab txhim kho cov dej ua ke, ua kom muaj cov kua muag, cov khoom lag luam juicier.
Cov khoom siv gluten-dawb: CMC yog qee zaum siv nyob rau hauv gluten-dawb cov zaub mov rau mimic cov kev ntxhib los mos thiab qauv uas gluten feem ntau muab.
Cov khoom noj tsiaj: CMC tseem siv hauv kev lag luam tsiaj tsiaj los txhim kho cov qauv thiab cov tsos tsiaj.
Kev Txiav Txim Siab:
Khoom Noj Khoom Noj Qib CMC yog suav tias yog muaj kev nyab xeeb rau kev noj thaum siv nyob rau hauv kev txwv tsis pub. Nws tau pom zoo los ntawm cov koom haum tswj hwm suav nrog Asmeskas Cov Khoom Noj thiab Tshuaj Noj (EFSA) yog cov kev coj noj coj ua nyab xeeb thaum siv raws li cov kev tsim khoom zoo (GMP).
Txawm li cas los xij, cov qib kev pom zoo siv yuav tsum tau ua raws li kom ntseeg tau tias kev nyab xeeb zaub mov lom zem kawg. Kev noj ntau dhau ntawm CMC tuaj yeem ua rau mob plab zom mov ua rau qee tus neeg. Zoo li cov zaub mov ntxiv, cov neeg uas muaj kev sib koom ua ke tshwj xeeb lossis ua xua yuav tsum ceev faj kom ceev faj thiab nrhiav kev pab kho mob.
Hauv kev xaus:
Khoom Noj Khoom Noj Qib Sodium Carboxymethyl cellulose (CMC) Ua kom muaj kev lag luam tseem ceeb, kev ruaj khov thiab tag nrho cov khoom noj khoom haus. Nws cov khoom ntiag tug, suav nrog solubility, suav nrog kev tawm tsam, viscosity modulation thiab zaj duab xis-ua lub peev xwm, ua rau nws muaj ntau yam kev siv. Lub txheej txheem ntau lawm ua kom muaj kev coj dawb huv thiab kev nyab xeeb ntawm cov zaub mov-qib CMC, thiab cov kev cai tswj hwm kev pom zoo uas tsis tau siv rau hauv cov khoom noj khoom noj khoom haus. Raws li nrog cov zaub mov ntxiv, lub luag haujlwm thiab paub siv yog qhov tseem ceeb los tswj cov khoom muaj kev nyab xeeb thiab cov neeg tau txais kev txaus siab.
