Sodium carboxymethyl cellulose e tooj

Taw qhia

Sodium carboxymethyl cellulose (CMC) yog cov khoom noj khoom haus dav siv nrog E tus lej E466.Nws yog cov hmoov dawb, tsis muaj ntxhiab, tsis qab, uas yog siv los ua cov thickener thiab stabilizer hauv ntau cov khoom noj.CMC yog ib qho derivative ntawm cellulose, ib txwm tshwm sim polysaccharide pom nyob rau hauv cov nroj tsuag.Nws yog tsim los ntawm reacting cellulose nrog sodium hydroxide thiab monochloroacetic acid.CMC yog siv rau hauv ntau yam khoom noj khoom haus, xws li ice cream, zaub nyoos hnav khaub ncaws, kua ntses, thiab khoom ci.Nws kuj tseem siv rau hauv cov tshuaj, tshuaj pleev ib ce, thiab tshuaj detergents.

Chemical Structure

Sodium carboxymethyl cellulose yog anionic polysaccharide tsim los ntawm kev rov ua dua ntawm D-glucose thiab D-mannose.Cov qauv tshuaj lom neeg ntawm CMC tau qhia hauv daim duab 1. Cov chav ua haujlwm rov ua dua yog txuas ua ke los ntawm glycosidic bonds.Cov pawg carboxymethyl txuas nrog rau pawg hydroxyl ntawm cov piam thaj thiab mannose units.Qhov no muab cov molecule ib tug tsis zoo nqi, uas yog lub luag hauj lwm rau nws cov dej-soluble zog.

Cov khoom

Sodium carboxymethyl cellulose muaj ntau yam khoom tshwj xeeb uas ua rau nws muaj txiaj ntsig zoo hauv cov khoom noj.Nws yog ib qho tsis muaj tshuaj lom, tsis ua rau khaus, thiab tsis ua xua.Nws kuj yog ib qho zoo heev thickener thiab stabilizer, uas ua rau nws zoo tagnrho rau siv hauv cov kua ntses thiab hnav khaub ncaws.CMC kuj yog ib qho zoo emulsifier, uas yuav pab kom cov roj thiab dej-raws li cov khoom sib cais.Nws kuj tseem tiv taus cua sov, kua qaub, thiab alkali, uas ua rau nws haum rau siv ntau yam khoom noj.

Siv

Sodium carboxymethyl cellulose yog siv nyob rau hauv ntau yam khoom noj khoom haus, xws li ice cream, salad dressings, sauces, thiab ci.Nws kuj tseem siv rau hauv cov tshuaj, tshuaj pleev ib ce, thiab tshuaj ntxuav tes.Hauv cov khoom noj khoom haus, CMC yog siv los ua cov thickener, stabilizer, thiab emulsifier.Nws pab kom cov khoom sib cais los ntawm kev sib cais thiab txhim kho kev ntxhib los mos thiab sib xws ntawm cov khoom.Hauv kev siv tshuaj, CMC yog siv los ua ib qho kev sib khi thiab disintegrant.Hauv cov tshuaj pleev ib ce, nws yog siv los ua cov thickener thiab stabilizer.Hauv detergents, nws yog siv los ua ib qho dispersant thiab emulsifier.

Kev nyab xeeb

Sodium carboxymethyl cellulose feem ntau lees paub tias muaj kev nyab xeeb (GRAS) los ntawm US Food and Drug Administration (FDA).Nws kuj tau pom zoo siv rau hauv cov khoom noj khoom haus hauv European Union.CMC tsis muaj tshuaj lom thiab tsis ua xua, thiab nws tau siv rau hauv cov khoom noj rau ntau tshaj 50 xyoo.Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias CMC tuaj yeem nqus dej, uas tuaj yeem ua rau nws o thiab ua kom khov.Qhov no tuaj yeem ua rau txhaws yog tias cov khoom noj tsis zoo.
