Khoom noj khoom haus Additive Sodium Carboxymethyl Cellulose

Sodium carboxymethyl cellulose (CMC), feem ntau hu ua carboxymethyl cellulose (CMC) los yog cellulose gum, yog ntau yam khoom noj additive nrog ntau yam kev siv hauv kev lag luam khoom noj. Nws yog muab los ntawm cellulose, ib txwm tshwm sim polysaccharide pom nyob rau hauv cell phab ntsa ntawm cov nroj tsuag. CMC feem ntau yog siv los ua cov thickener, stabilizer, emulsifier, thiab tus neeg saib xyuas cov dej noo hauv ntau yam khoom noj. Nws cov khoom tshwj xeeb ua rau nws tseem ceeb hauv kev tsim khoom ntawm ntau yam khoom noj.

Chemical Structure thiab Properties

CMC yog synthesized los ntawm kev kho cellulose nrog sodium hydroxide thiab monochloroacetic acid, uas ua rau muaj kev hloov ntawm hydroxyl pawg nrog carboxymethyl pawg. Qhov kev hloov kho no ua rau dej solubility rau cellulose molecule, tso cai rau nws ua haujlwm zoo li cov khoom noj ntxiv. Qhov degree ntawm kev hloov pauv (DS) txiav txim siab theem ntawm kev hloov pauv ntawm carboxymethyl pawg ib chav tsev anhydroglucose hauv cov saw cellulose, cuam tshuam rau nws cov solubility, viscosity, thiab lwm yam khoom siv.

CMC muaj nyob rau hauv ntau hom, nrog rau cov hmoov, granules, thiab cov kev daws teeb meem, nyob ntawm seb lub hom phiaj ntawm daim ntawv thov. Nws tsis muaj ntxhiab tsw, tsis qab, thiab feem ntau yog xim dawb mus rau xim dawb. Lub viscosity ntawm SCMC cov kev daws teeb meem tuaj yeem hloov kho los ntawm ntau yam xws li cov concentration ntawm cov tshuaj, qib ntawm kev hloov pauv, thiab pH ntawm qhov nruab nrab.

Muaj nuj nqi hauv Zaub Mov

Thickening: Ib qho ntawm cov haujlwm tseem ceeb ntawm CMC hauv cov khoom noj khoom haus yog ua kom viscosity thiab muab kev ntxhib los mos. Nws txhim kho qhov ncauj qhov ntswg ntawm cov kua ntsw, hnav khaub ncaws, thiab cov khoom siv mis nyuj, muab lawv ib qho smoother thiab txaus nyiam sib xws. Hauv cov khoom ci, CMC pab txhim kho lub khob noom cookie tuav thiab muab cov qauv rau cov khoom kawg.

Stabilizing: CMC ua tus stabilizer los ntawm kev tiv thaiv kev sib cais ntawm cov khoom xyaw hauv cov khoom noj. Nws pab tshem tawm cov khoom hauv cov dej haus, xws li kua txiv hmab txiv ntoo thiab cov dej qab zib, tiv thaiv sedimentation thiab tswj cov khoom sib xws thoob plaws hauv txee lub neej. Hauv cov dej khov thiab cov khoom qab zib khov, CMC inhibits crystallization thiab txhim kho cov creaminess ntawm cov khoom.

Emulsifying: Raws li ib qho emulsifier, CMC pab txhawb kev tawg ntawm cov khoom tsis zoo, xws li roj thiab dej, hauv cov khoom noj. Nws stabilizes emulsions, xws li zaub xam lav hnav khaub ncaws thiab mayonnaise, los ntawm kev tsim cov yeeb yaj kiab tiv thaiv ib puag ncig cov tee dej, tiv thaiv coalescence thiab ua kom ruaj khov mus ntev.

Moisture Retention: CMC muaj cov khoom hygroscopic, txhais tau tias nws tuaj yeem nyiam thiab khaws cov dej noo. Hauv cov khoom ci, nws pab ua kom lub neej tshiab thiab txee lub neej los ntawm kev txo qis thiab tswj cov dej noo. Tsis tas li ntawd, hauv cov khoom noj nqaij thiab nqaij qaib, CMC tuaj yeem txhim kho cov kua dej thiab tiv thaiv kom tsis txhob ya raws thaum ua noj thiab khaws cia.

Zaj duab xis-Forming: CMC tuaj yeem tsim cov yeeb yaj kiab hloov tau yooj yim thiab pob tshab thaum ziab, ua rau nws tsim nyog rau cov ntawv thov xws li cov txheej txheem edible thiab encapsulation ntawm cov khoom xyaw. Cov yeeb yaj kiab no muab kev tiv thaiv kev tiv thaiv kev ya raws, oxygen, thiab lwm yam sab nraud, ua rau lub neej txee ntawm cov khoom puas tsuaj.

Daim ntawv thov

CMC pom kev siv dav hauv ntau yam khoom noj khoom haus thoob plaws ntau pawg:

Cov Khoom Siv Bakery: Cov khob cij, ncuav mog qab zib, pastries, thiab biscuits tau txais txiaj ntsig los ntawm CMC muaj peev xwm los txhim kho cov khob noom cookie, kev ntxhib los mos, thiab txee lub neej.
Khoom noj khoom haus thiab khoom qab zib: Ice cream, yogurt, custards, thiab puddings siv SCMC rau nws stabilizing thiab thickening zog.
Dej Haus: Cov dej qab zib, kua txiv hmab txiv ntoo, thiab cov dej cawv siv CMC los tiv thaiv theem kev sib cais thiab tswj cov khoom sib xws.
Sauces thiab Dressings: Salad dressings, gravy, sauces, thiab condiments cia siab rau CMC rau viscosity tswj thiab stability.
Nqaij thiab nqaij qaib cov khoom: Cov nqaij ua tiav, hnyuv ntxwm, thiab cov nqaij analogs siv CMC los txhim kho cov dej noo thiab kev ntxhib los mos.
Confections: Candies, gummies, thiab marshmallows tau txais txiaj ntsig los ntawm CMC lub luag haujlwm hauv kev hloov kho kev ntxhib los mos thiab kev tswj dej noo.

Kev tswj hwm raws li txoj cai thiab kev nyab xeeb
CMC tau pom zoo siv los ua zaub mov ntxiv los ntawm cov cai tswj hwm xws li US Food and Drug Administration (FDA) thiab European Food Safety Authority (EFSA). Nws feem ntau lees paub tias muaj kev nyab xeeb (GRAS) thaum siv raws li kev tsim khoom zoo thiab tsis pub dhau qhov txwv. Txawm li cas los xij, kev noj ntau dhau ntawm SCMC tuaj yeem ua rau plab hnyuv tsis xis nyob hauv cov tib neeg rhiab heev.

sodium carboxymethyl cellulose yog cov khoom noj muaj txiaj ntsig zoo uas ua rau muaj txiaj ntsig zoo, ruaj khov, thiab ua haujlwm ntawm ntau yam khoom noj. Nws lub luag haujlwm ntau yam ua cov thickener, stabilizer, emulsifier, thiab tus neeg saib xyuas cov dej noo ua rau nws tseem ceeb hauv kev tsim khoom noj niaj hnub no, ua kom muaj ntau yam khoom noj uas muaj txiaj ntsig zoo thiab lub neej ntev.
