Carboxymethyl cellulose sodium (CMC)yog ib qho fiber ntau uas yaj tau hauv dej thiab yog ib yam khoom siv ntxiv uas siv dav hauv kev lag luam zaub mov. Nws ua rau nws tuab, ruaj khov, emulsifying, thiab khaws dej tau zoo heev. Nws txoj kev nyab xeeb thiab kev tswj xyuas zoo muaj feem cuam tshuam ncaj qha rau qhov zoo ntawm zaub mov thiab kev noj qab haus huv ntawm cov neeg siv khoom. Yog li ntawd, cov teb chaws thoob ntiaj teb tau tsim cov cai thiab cov qauv nruj rau CMC qib zaub mov.
1. Cov Cai Tswjfwm Thoob Ntiaj Teb rau CMC Qib Khoom Noj
1.1. Pawg Neeg Kws Tshaj Lij Sib Koom Tes ntawm FAO/WHO txog Cov Khoom Noj Khoom Haus Ntxiv (JECFA)
Pawg Neeg Saib Xyuas Kev Sib Koom Tes ntawm Cov Khoom Noj Khoom Haus Ntxiv (JECFA) ntawm Lub Koom Haum Khoom Noj thiab Kev Ua Liaj Ua Teb ntawm United Nations (FAO) thiab Lub Koom Haum Kev Noj Qab Haus Huv Ntiaj Teb (WHO) tau teev CMC rau hauv Daim Ntawv Teev Cov Khoom Noj Khoom Haus Zoo txij li xyoo 1963.
1.2. Tus lej INS: 466

JECFA cov kev cai zoo rau CMC qib zaub mov suav nrog kev huv, qib hloov pauv (DS 0.6-1.0), pH (6.0-8.5), thiab cov hlau hnyav (piv txwv li, txhuas ≤ 2 mg / kg).
1.4. Codex Alimentarius
Lub Codex Alimentarius Commission (CAC) txhais cov kev siv thiab cov qib siab tshaj plaws ntawm CMC hauv ntau pawg khoom noj sib txawv hauv nws Tus Txheej Txheem Dav Dav rau Cov Khoom Noj Ntxiv (GSFA). Piv txwv li:
Cov khoom noj mis nyuj (piv txwv li, ice cream, cov khoom noj mis nyuj fermented): Qib siab tshaj plaws siv 10,000 mg/kg;
Cov dej haus txiv hmab txiv ntoo, cov kua ntses, thiab cov khoom ci: Feem ntau tsis pub tshaj 5,000 mg/kg;
Feem ntau tsis pub siv cov mis mos rau menyuam yaus.
2. Tuam Tshoj txoj Kev Tswj Xyuas CMC Qib Khoom Noj
Tus Txheej Txheem Kev Nyab Xeeb Khoom Noj Hauv Tebchaws GB 1886.232-2016 "Cov Khoom Noj Ntxiv - Sodium Carboxymethyl Cellulose"
Tus qauv no ua lub hauv paus rau kev tswj xyuas zoo ntawm CMC hauv kuv lub tebchaws. Cov kev cai tseem ceeb suav nrog:
2.1. Tsos: Dawb los yog me ntsis daj hmoov;
Qib Kev Hloov Chaw (DS): 0.6-0.95;

Arsenic (Raws li): ≤1 mg/kg.
2.2. Tus Qauv Siv: GB 2760 "Tus Qauv Siv Cov Khoom Noj Khoom Haus Ntxiv"
CMC yog ib yam khoom uas ua rau tuab thiab ruaj khov thiab siv tau rau ntau yam khoom noj. Cov kev siv thiab cov kev txwv feem ntau yog raws li nram no:
Kas fes khov, jelly, pasta, kua ntses: Siv rau hauv qhov ntau thiab tsawg raws li qhov xav tau ntawm kev tsim khoom;
Dej haus: Siv ntau tshaj 0.5%;
Cov khoom noj mis nyuj: Siv ntau tshaj 0.3%;
Khoom noj rau menyuam mos thiab menyuam yaus: Txwv tsis pub noj.
2.3. Cov Cai thiab Cov Kev Cai rau Kev Sau Npe
Cov chaw tsim khoom yuav tsum muaj Daim Ntawv Tso Cai Tsim Khoom Noj Khoom Haus (SC tus lej), thiab lawv cov khoom yuav tsum tau sau npe nrog Lub Chaw Haujlwm Saib Xyuas Kev Lag Luam Hauv Xeev. Cov khoom xa tawm kuj yuav tsum ua raws li cov qauv ntawm lub tebchaws xa khoom (piv txwv li, EU E466, US FCC, thiab lwm yam).
3. Kev Txheeb Xyuas Txog Cov Qauv Hauv Tebchaws Europe, Amelikas, thiab Lwm Thaj Chaw
3.1. Tus Qauv EU (E466)
EU Txoj Cai (EU) No. 231/2012 xaiv CMC ua cov khoom noj khoom haus uas tau xaiv los ntawm E466.
Nws raug tso cai siv ua cov khoom siv tuab thiab stabilizer.
Cov kev cai rau qib kev hloov pauv, cov ntsiab lus hlau hnyav, thiab cov cim qhia txog microbiological feem ntau yog sib xws nrog cov ntawm JECFA.
Tsis pub siv rau hauv cov mis mos rau menyuam yaus.
3.2. Cov Cai ntawm FDA hauv Tebchaws Meskas (21 CFR 182.1745)
CMC yog teev raws li GRAS (Generally Recognized As Safe) tshuaj thiab siv tau rau hauv cov khoom noj.
Nws siv yog raws li Kev Ua Haujlwm Zoo (GMP).
Nws yog siv rau hauv ice cream, salad dressings, jellies, baked goodies, thiab lwm yam.
FDA xav tau cov khoom siv raw khoom zoo thiab cov txheej txheem taug qab tau.
3.3. Cov Qauv Nyiv Pooj thiab Kauslim Teb
Cov qauv ntawm ob lub tebchaws no ua raws li "Cov Qauv Khoom Noj Khoom Haus" thiab "Cov Qauv Khoom Noj Khoom Haus," raws li. CMC yuav tsum ua tau raws li cov qauv kev huv thiab cov kev txwv ntawm cov kab mob me me, thiab nws qhov kev siv zoo ib yam li EU.
4. Cov Ntsiab Lus Tseem Ceeb hauv Kev Ntsuas thiab Kev Tswj Xyuas Zoo
Kev kuaj CMC rau cov khoom noj feem ntau suav nrog cov khoom siv lub cev thiab tshuaj lom neeg, cov ntsuas kev huv, thiab cov ntsuas kev nyab xeeb:
Kev ntsuam xyuas lub cev thiab tshuaj lom neeg: viscosity, degree of substitution, pH, noo noo, tshauv cov ntsiab lus;
Kev ntsuam xyuas kev nyab xeeb: cov hlau hnyav, arsenic, txhuas, thiab tag nrho cov kab mob me me;
Kev ntsuam xyuas kev ua haujlwm: solubility, rheological properties, stability, thiab lwm yam. Cov khoom noj khoom haus zoo CMC yuav tsum muaj cov yam ntxwv xws li pob tshab siab, tsis muaj ntxhiab, solubility zoo, thiab rheological profile ruaj khov.
5. Cov Qauv Cai thiab Kev Txhim Kho Kev Lag Luam
Nrog rau kev nce ntxiv ntawm "daim ntawv lo huv" thiab kev noj qab haus huv, CMC qib zaub mov tau raug tswj hwm nruj dua:
Cov txheej txheem tsim khoom yuav tsum tsis muaj cov kuab tshuaj uas ua rau puas tsuaj (xws li isopropyl cawv);
Kev hloov mus rau "cov khoom siv los ntawm ntuj" thiab "cov fibers uas lwj tau" tab tom pib;
Cov tuam txhab yuav tsum tau txais ntau daim ntawv pov thawj, suav nrog ISO 22000, HACCP, HALAL, thiab KOSHER.
Yav tom ntej, cov cai thiab cov qauv ntawm CMC yuav sib haum nrog cov qauv thoob ntiaj teb, muab kev tsom mus rau kev nyab xeeb ntawm cov khoom siv, kev phooj ywg ib puag ncig, thiab kev cuam tshuam rau tib neeg kev noj qab haus huv.
Lub kaw lus tswj hwm thiab tus qauv rauCMC qib zaub movtab tom dhau los ua qhov dav dua, npog tag nrho cov khoom xa tuaj los ntawm cov khoom siv raw, kev tsim khoom, thiab kev siv. Cov tuam txhab yuav tsum ua raws li cov qauv hauv tebchaws xws li GB 1886.232 thiab GB 2760 thaum lub sijhawm R & D thiab xa tawm, thiab saib xyuas cov kev hloov tshiab los ntawm JECFA, EU, thiab FDA. Tsuas yog siv nws tsim nyog hauv cov txheej txheem kev cai lij choj peb tuaj yeem ua kom ntseeg tau tias kev ua haujlwm thiab kev nyab xeeb ntawm CMC hauv zaub mov tau muab qhov tseem ceeb sib npaug thiab txhawb kev txhim kho kev lag luam zaub mov.
