E466 Khoom noj khoom haus ntxiv - Sodium Carboxymethyl Cellulose

Sodium Carboxymethyl Cellulose(SCMC) yog ib qho khoom noj khoom haus uas siv ntau yam khoom noj, nrog rau cov khoom ci, khoom noj siv mis, dej haus, thiab kua ntses. Nws kuj yog siv nyob rau hauv lwm yam kev lag luam, xws li tshuaj, tshuaj pleev ib ce, thiab ntawv ntau lawm. Hauv tsab xov xwm no, peb yuav ua tib zoo saib ntawm SCMC, nws cov khoom, kev siv, kev nyab xeeb, thiab kev pheej hmoo.

Cov khoom thiab kev tsim khoom ntawm SCMC

Sodium Carboxymethyl Cellulose yog derivative ntawm cellulose, uas yog ib txwm tshwm sim polymer ua los ntawm cov piam thaj units. SCMC yog tsim los ntawm kev kho cellulose nrog tshuaj hu ua monochloroacetic acid, uas ua rau cov cellulose ua carboxymethylated. Qhov no txhais tau hais tias carboxymethyl pawg (-CH2-COOH) tau ntxiv rau hauv cov pob txha cellulose, uas muab nws cov khoom tshiab xws li nce solubility hauv dej thiab txhim kho kev sib khi thiab ua kom tuab.

SCMC yog cov hmoov dawb mus rau dawb uas tsis muaj ntxhiab thiab tsis qab. Nws yog heev soluble nyob rau hauv dej, tab sis insoluble nyob rau hauv feem ntau cov organic solvents. Nws muaj viscosity siab, uas txhais tau hais tias nws muaj peev xwm ua kom cov kua dej tuab, thiab nws tsim cov gels nyob rau hauv muaj qee yam ions, xws li calcium. Lub viscosity thiab gel-forming zog ntawm SCMC tuaj yeem hloov kho los ntawm kev hloov cov qib ntawm carboxymethylation, uas cuam tshuam rau cov carboxymethyl pawg ntawm cov pob txha cellulose.

Kev siv SCMC hauv Khoom Noj

SCMC yog dav siv hauv kev lag luam khoom noj khoom haus raws li cov khoom noj khoom haus ntxiv, feem ntau yog cov thickener, stabilizer, thiab emulsifier. Nws yog feem ntau siv hauv cov khoom ci xws li qhob cij, khoom qab zib, thiab pastries, los txhim kho lawv cov kev ntxhib los mos, ua kom lawv cov txee lub neej, thiab tiv thaiv lawv los ntawm staling. Hauv cov khoom siv mis nyuj xws li yogurt, ice cream, thiab cheese, nws yog siv los txhim kho lawv cov kev ntxhib los mos, tiv thaiv kev sib cais, thiab ua kom lawv ruaj khov. Hauv cov dej haus xws li cov dej qab zib thiab cov kua txiv hmab txiv ntoo, nws yog siv los ua kom cov kua dej ruaj khov thiab tiv thaiv kev sib cais.

SCMC kuj tseem siv rau hauv cov kua ntses, hnav khaub ncaws, thiab cov khoom noj xws li ketchup, mayonnaise, thiab mustard, kom tuab lawv thiab txhim kho lawv cov kev ntxhib los mos. Nws yog siv rau hauv cov khoom siv nqaij xws li hnyuv ntxwm thiab nqaij npuas, txhawm rau txhim kho lawv cov khoom sib txuas thiab tiv thaiv kom tsis txhob poob thaum ua noj. Nws kuj yog siv rau hauv cov khoom noj muaj roj tsawg thiab txo cov calories, los hloov cov rog thiab txhim kho kev ntxhib los mos.

SCMC feem ntau suav tias muaj kev nyab xeeb rau kev siv khoom noj los ntawm cov koom haum tswj hwm thoob ntiaj teb, suav nrog US Food and Drug Administration (FDA) thiab European Food Safety Authority (EFSA).

Kev nyab xeeb ntawm SCMC hauv Khoom Noj

SCMC tau kawm ntau ntxiv txog nws txoj kev nyab xeeb hauv cov zaub mov, thiab nws tau pom tias muaj kev nyab xeeb rau tib neeg noj ntawm cov qib siv hauv cov khoom noj. Lub Koom Haum Koom Tes FAO/WHO Cov Kws Tshaj Lij Tshaj Lij rau Cov Khoom Noj Ntxiv (JECFA) tau tsim kom muaj kev noj qab haus huv txhua hnub (ADI) ntawm 0-25 mg / kg lub cev qhov hnyav rau SCMC, uas yog tus nqi ntawm SCMC uas tuaj yeem noj txhua hnub hauv lub neej yam tsis muaj cuam ​​tshuam.

Cov kev tshawb fawb tau pom tias SCMC tsis muaj tshuaj lom, carcinogenic, mutagenic, lossis teratogenic, thiab nws tsis ua rau muaj kev cuam tshuam rau kev ua me nyuam los yog kev loj hlob. Nws tsis yog metabolized los ntawm lub cev thiab raug tshem tawm tsis hloov pauv hauv cov quav, yog li nws tsis khaws cia hauv lub cev.

Txawm li cas los xij, qee tus neeg yuav muaj kev fab tshuaj rau SCMC, uas tuaj yeem ua rau cov tsos mob xws li khaus khaus, khaus, o, thiab ua pa nyuaj. Cov tshuaj tiv thaiv no tsis tshua muaj tab sis tuaj yeem hnyav rau qee kis. Yog tias koj muaj cov tsos mob no tom qab noj cov khoom noj uas muaj SCMC, koj mus ntsib koj tus kws kho mob tam sim ntawd.

Muaj peev xwm txaus ntshai ntawm SCMC

Thaum SCMC feem ntau suav hais tias muaj kev nyab xeeb rau tib neeg noj, muaj qee qhov kev pheej hmoo cuam tshuam nrog nws siv. Ib qho kev txhawj xeeb tseem ceeb yog nws cov txiaj ntsig ntawm lub plab zom mov. SCMC yog ib qho fiber ntau soluble, uas txhais tau hais tias nws tuaj yeem nqus dej thiab tsim cov gel zoo li hauv cov hnyuv. Qhov no tuaj yeem ua rau muaj teeb meem digestive xws li tsam plab, roj, thiab raws plab hauv qee tus neeg, tshwj xeeb yog noj ntau heev.

Lwm qhov kev pheej hmoo yog nws cov txiaj ntsig ntawm kev nqus cov as-ham. Vim tias SCMC tuaj yeem tsim cov gel zoo li hauv cov hnyuv, nws tuaj yeem cuam tshuam nrog kev nqus ntawm cov as-ham, tshwj xeeb tshaj yog cov vitamins muaj roj xws li A, D, E, thiab K. tshwj xeeb tshaj yog tias noj ntau npaum li niaj zaus.

Nws tseem tsim nyog sau cia tias qee qhov kev tshawb fawb tau qhia tias SCMC tuaj yeem cuam tshuam tsis zoo rau lub plab noj qab haus huv. Ib txoj kev tshawb fawb luam tawm nyob rau hauv phau ntawv Journal Nature Communications hauv 2018 pom tias SCMC tuaj yeem cuam tshuam qhov sib npaug ntawm cov kab mob plab hauv cov nas, uas ua rau muaj mob thiab lwm yam teeb meem kev noj qab haus huv. Thaum xav tau kev tshawb fawb ntxiv kom nkag siab txog qhov cuam tshuam ntawm SCMC rau lub plab noj qab haus huv hauv tib neeg, qhov no yog ib qho kev txhawj xeeb uas yuav tsum tau saib xyuas.

Sodium Carboxymethyl Cellulose yog ib qho khoom noj khoom haus uas tau siv dav uas pom tau tias muaj kev nyab xeeb rau tib neeg noj. Nws yog siv feem ntau ua cov thickener, stabilizer, thiab emulsifier hauv ntau yam khoom noj, nrog rau cov khoom ci, khoom noj siv mis, dej haus, thiab kua ntses. Txawm hais tias muaj qee qhov kev pheej hmoo uas cuam tshuam nrog nws txoj kev siv, tshwj xeeb tshaj yog nyob rau hauv loj, tag nrho kev nyab xeeb ntawm SCMC tau tsim los ntawm cov koom haum tswj hwm thoob ntiaj teb.

Raws li nrog rau cov khoom noj ntxiv, nws yog ib qho tseem ceeb uas yuav tsum tau siv SCMC hauv kev sib haum xeeb thiab kom paub txog tej yam muaj peev xwm rhiab lossis ua xua. Yog tias koj muaj kev txhawj xeeb txog kev siv SCMC hauv cov khoom noj, sab laj nrog koj tus kws kho mob lossis tus kws kho mob sau npe.
