Hauv cov ntawv thov zaub mov, sodium carboxymethyl cellulose (CMC) yog siv los ua cov khoom noj ntxiv nrog ntau lub zog, suav nrog kev ua kom tuab, ruaj khov, emulsifying, thiab tswj cov dej noo. Txhawm rau kom muaj kev nyab xeeb thiab zoo ntawm cov khoom noj khoom haus, muaj cov cai tshwj xeeb thiab cov cai tswj kev siv CMC. Nov yog qee qhov tseem ceeb rau CMC hauv cov ntawv thov zaub mov:

1. Txoj Cai Pom Zoo:
   • CMC siv rau hauv daim ntawv thov zaub mov yuav tsum ua raws li cov qauv kev cai thiab tau txais kev pom zoo los ntawm cov tub ceev xwm, xws li US Food and Drug Administration (FDA), European Food Safety Authority (EFSA), thiab lwm lub koom haum tswj hwm hauv ntau lub teb chaws.
   • CMC yuav tsum raug lees paub raws li Kev Pom Zoo Raws Li Kev Nyab Xeeb (GRAS) lossis pom zoo siv los ua cov khoom noj ntxiv hauv cov kev txwv tshwj xeeb thiab raws li cov xwm txheej tshwj xeeb.
2. Purity thiab Quality:
   • CMC siv nyob rau hauv daim ntawv thov zaub mov yuav tsum tau raws li nruj purity thiab zoo cov qauv los xyuas kom meej nws kev nyab xeeb thiab ua tau zoo.
   • Nws yuav tsum tsis txhob muaj cov kab mob sib kis, xws li cov hlau hnyav, cov kab mob microbial, thiab lwm yam khoom tsis zoo, thiab ua raws li cov kev txwv siab tshaj plaws uas tau teev tseg los ntawm cov cai tswj hwm.
   • Qhov degree ntawm kev hloov pauv (DS) thiab viscosity ntawm CMC tuaj yeem sib txawv nyob ntawm qhov xav tau ntawm daim ntawv thov thiab kev tswj hwm.
3. Labeling Requirements:
   • Cov khoom noj khoom haus uas muaj CMC ua cov khoom xyaw yuav tsum yog daim ntawv lo nws muaj thiab ua haujlwm hauv cov khoom.
   • Daim ntawv lo yuav tsum suav nrog lub npe "carboxymethyl cellulose" lossis "sodium carboxymethyl cellulose" hauv cov npe khoom, nrog rau nws cov haujlwm tshwj xeeb (xws li, thickener, stabilizer).
4. Kev siv qib:
   • CMC yuav tsum tau siv nyob rau hauv daim ntawv thov zaub mov nyob rau hauv cov kev siv theem thiab raws li Good Manufacturing Practices (GMP).
   • Cov koom haum tswj hwm muab cov lus qhia thiab kev txwv siab tshaj plaws rau kev siv CMC hauv ntau yam khoom noj khoom haus raws li nws qhov kev npaj ua haujlwm thiab kev saib xyuas kev nyab xeeb.
5. Kev soj ntsuam kev nyab xeeb:
   • Ua ntej CMC tuaj yeem siv rau hauv cov khoom noj khoom haus, nws txoj kev nyab xeeb yuav tsum raug soj ntsuam los ntawm kev soj ntsuam kev tshawb fawb nruj, suav nrog kev tshawb fawb txog tshuaj lom neeg thiab kev ntsuam xyuas raug.
   • Cov cai tswjfwm saib xyuas cov ntaub ntawv kev nyab xeeb thiab ua cov kev ntsuas kev pheej hmoo kom ntseeg tau tias kev siv CMC hauv cov ntawv thov zaub mov tsis ua rau muaj kev phom sij rau cov neeg siv khoom.
6. Daim ntawv tshaj tawm Allergen:
   • Txawm hais tias CMC tsis paub tias yog ib qho kev ua xua, cov khw muag khoom noj yuav tsum tshaj tawm nws qhov muaj nyob rau hauv cov khoom noj kom qhia rau cov neeg siv khoom muaj kev fab tshuaj lossis rhiab heev rau cellulose derivatives.
7. Cia thiab tuav:
   • Cov chaw tsim khoom noj khoom haus yuav tsum khaws thiab tswj CMC raws li kev pom zoo khaws cia kom muaj kev ruaj ntseg thiab zoo.
   • Kev sau npe kom raug thiab cov ntaub ntawv ntawm CMC batch yog tsim nyog los xyuas kom meej traceability thiab ua raws li cov cai tswj.

Kev ua raws li cov qauv kev tswj hwm, kev ua kom huv huv thiab kev ua tau zoo, kev sau npe kom raug, qib kev siv tsim nyog, kev ntsuas kev nyab xeeb, thiab kev khaws cia thiab kev coj ua kom zoo yog qhov tseem ceeb rau kev siv CMC hauv cov ntawv thov zaub mov. Los ntawm ua tau raws li cov cai no, cov tuam txhab khoom noj tuaj yeem ua kom muaj kev nyab xeeb, zoo, thiab ua raws li cov khoom noj khoom haus uas muaj CMC ua cov khoom xyaw.
