Carboxymethylcellulose (CMC) yog qhov kev lag luam ntau ntxiv, tshwj xeeb hauv kev lag luam khoom noj uas nws suav hais tias yog cov khoom noj khoom noj ntxiv. Qhov no sib xyaw no tau muab los ntawm cellulose, lub ntuj polymer pom hauv tsob ntoo cell phab ntsa. Los ntawm cov tshuaj lom neeg cov tshuaj lom neeg, carboxymethyl cellulose tsim tawm, muab nws cov khoom tshwj xeeb thiab ua rau nws muaj nuj nqis rau ntau yam kev siv.
Cov qauv thiab kev tsim khoom:
Cellulose yog cov carbohydrate ntau thiab yog qhov tseem ceeb ntawm CMC. Cellulose feem ntau yog muab los ntawm ntoo pulp lossis paj rwb fibers. Cov txheej txheem ntau lawm koom nrog kho cellulose nrog sodium hydroxide los tsim alkali cellulose. Tom qab, CarnoKethyl pawg yog qhia rau hauv lub cellulose backulose uas siv chloroacetic acid. Cov degree ntawm lub txiaj ntsig carboxymethyl cellulose tuaj yeem sib txawv thiab yog hais txog pes tsawg tus carboxymethyl pab pawg ntxiv rau chav dej hauv lub cellulose.
Cov yam ntxwv:
CMC muaj ob peb key Properties uas pab txhawb rau nws cov kev siv:
Dej Solubility: CMC yog dej-soluble thiab ua ib pob tshab thiab khov kho hauv dej. Cov cuab yeej no yog qhov tseem ceeb rau nws siv nyob rau ntau yam kua formulations.
Thickeners: Raws li cov tuab dua, cmc feem ntau siv los ua kom cov viscosity ntawm cov zaub mov noj. Cov cuab yeej no yog tau txais txiaj ntsig tshwj xeeb rau kev txhim kho kev ntxhib los mos thiab qhov ncauj ntawm cov kua ntses, hnav khaub ncaws thiab lwm yam zaub noj kua.
Stabilizer: CMC ua raws li lub stabilizer nyob rau ntau cov zaub mov, tiv thaiv cov khoom xyaw los ntawm kev sib cais lossis kev sib cais thaum lub sijhawm cia. Qhov no yog qhov tseem ceeb los tswj kev sib dhos ntawm daim ntawv qhia.
Zaj duab xis-tsim: CMC muaj zaj duab xis-ua yeeb yaj kiab ua yeeb yaj kiab thiab tuaj yeem siv ua txheej txheej rau confectiony cov khoom xws li Candies thiab Chocolates. Zaj duab xis tsim pab tswj kom zoo thiab pom ntawm cov khoom.
Kev siv tus neeg sawv cev: Txog kev haus dej haus thiab qee cov zaub mov, cmc yog siv los ua cov neeg sawv cev ncua los tiv thaiv cov lus los tiv thaiv. Qhov no ua kom muaj kev faib tawm cov khoom xyaw tsis sib xws.
Kev kho: CMC ua raws li phau ntawv nyob hauv cov khoom noj khoom noj, pab rau khi cov khoom xyaw ua ke thiab txhim kho cov qauv txheej txheem ntawm cov khoom kawg.
Tsis-toxic thiab inert: Cov Khoom Noj-Cov Khoom Noj CMC yog suav tias yog muaj kev noj khoom haus tsis muaj txiaj ntsig vim tias nws tsis yog tshuaj lom thiab inert. Nws tsis ua los ntawm cov qab tsw lossis xim rau cov zaub mov uas nws siv.
Cov ntawv thov hauv cov zaub mov hauvUSTRY:
Carboxymetylcellulose yog dav siv nyob rau hauv kev lag luam khoom noj khoom haus thiab pab txhim kho qhov zoo thiab muaj kev sib cav sib zog 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 thiab cov ncuav los txhim kho kev ntxhib los mos, noo noo khaws thiab txee lub neej.
Cov khoom noj siv mis: hauv cov khoom noj siv mis xws li cov mis nyuj khov thiab yogurt, cmc ua raws li lub stabilizer thiab pab tiv thaiv cov muaju hauv kev sib sau.
Cov kua thiab hnav khaub ncaws: CMC yog siv los ua tuab thiab ruaj khov, hnav khaub ncaws thiab cov khoom nyiam, txhim kho lawv cov khoom zoo tag nrho.
Haus: Siv rau hauv kev haus dej los tiv thaiv sedimentation thiab txhim kho partlete kev ncua, ua kom muaj txiaj ntsig cov khoom lag luam.
Confectionery: CMC yog siv rau hauv kev lag luam confectionery rau lub khob noom khoom qab zib thiab chocolates, muab cov txheej txheem tiv thaiv thiab txhim kho txheej txheem.
GLAZES thiab freshings: CMC pab txhim kho cov qauv thiab ruaj khov ntawm glazes thiab frostings siv hauv pastries thiab cov khoom qab zib.
Cov nqaij ntshiv: CMC ntxiv rau cov nqaij ua tiav los txhim kho cov dej khaws cia, kev ntxhib los mos thiab khicov khoom.
Kev tswj hwm cov xwm txheej thiab kev nyab xeeb:
Khoom Noj Khoom Noj Qib CMC yog tswj los ntawm cov chaw ua haujlwm nyab xeeb khoom noj thoob ntiaj teb. Nws yog feem ntau pom tau tias muaj kev nyab xeeb (gras) los ntawm Asmeskas Cov Khoom Noj thiab Tshuaj (FDA) thiab pom zoo rau kev siv ntau yam khoom noj khoom haus. Qhov sib koom ua ke FAO / WHo Sact Pawg Thawj Coj ntawm Cov Khoom Noj Ntxiv (Jecfa) thiab lwm lub koom haum kev cai tau raug ntsuas thiab txiav txim siab ntawm CMC rau kev siv khoom noj.
Carboxymetylcelleculose (CMC) yog ib qho tseem ceeb noj-qib ntxiv nrog ntau yam kev siv hauv kev lag luam khoom noj. Nws cov khoom muaj txiaj ntsig, xws li cov dej solubility, thickening muaj peev xwm thiab ua yeeb yaj kiab ua ke nyob rau hauv ntau yam khoom noj khoom noj khoom haus. Kev cai tswj nyeem thiab kev ntsuas kev nyab xeeb ntxiv qhia txog qhov nws haum rau cov khoom noj thiab dej haus kev lag luam.
