E466 Chakudya Chowonjezera - Sodium Carboxymethyl cellulose

Sodium Carboxymethyl cellulose(SCMC) ndi chowonjezera chazakudya chomwe chimagwiritsidwa ntchito muzakudya zambiri, kuphatikiza zophika, mkaka, zakumwa, ndi sosi.Amagwiritsidwanso ntchito m'mafakitale ena, monga opanga mankhwala, zodzoladzola, ndi kupanga mapepala.M'nkhaniyi, tiyang'anitsitsa SCMC, katundu wake, ntchito, chitetezo, ndi zoopsa zomwe zingatheke.

Katundu ndi Kupanga kwa SCMC

Sodium Carboxymethyl Cellulose ndi chochokera ku cellulose, chomwe ndi polima wopangidwa mwachilengedwe wopangidwa ndi mayunitsi a shuga.SCMC imapangidwa pochiza cellulose ndi mankhwala otchedwa monochloroacetic acid, omwe amachititsa kuti cellulose ikhale carboxymethylated.Izi zikutanthauza kuti magulu a carboxymethyl (-CH2-COOH) amawonjezedwa ku msana wa cellulose, womwe umapatsa zinthu zatsopano monga kusungunuka kwamadzi m'madzi komanso luso lomangirira ndi kukhuthala.

SCMC ndi ufa woyera mpaka woyera wopanda fungo komanso wosakoma.Ndiwosungunuka kwambiri m'madzi, koma osasungunuka m'ma organic solvents.Ili ndi mamasukidwe apamwamba, zomwe zikutanthauza kuti imatha kulimbitsa zakumwa, ndipo imapanga ma gels pamaso pa ayoni ena, monga calcium.Ma viscosity ndi gel-forming properties a SCMC akhoza kusinthidwa mwa kusintha mlingo wa carboxymethylation, zomwe zimakhudza kuchuluka kwa magulu a carboxymethyl pamsana wa cellulose.

Kugwiritsa ntchito SCMC mu Chakudya

SCMC imagwiritsidwa ntchito kwambiri m'makampani azakudya monga chowonjezera chazakudya, makamaka ngati chowonjezera, chokhazikika, ndi emulsifier.Nthawi zambiri amagwiritsidwa ntchito pophika monga buledi, makeke, ndi makeke, kuti asinthe mawonekedwe awo, awonjezere nthawi yawo ya alumali, komanso kuti asatayike.M’za mkaka monga yogati, ayisikilimu, ndi tchizi, amagwiritsidwa ntchito kuwongolera kaonekedwe kawo, kupeŵa kulekana, ndi kukulitsa kukhazikika kwake.Muzakumwa monga zakumwa zoziziritsa kukhosi ndi timadziti, amagwiritsidwa ntchito kukhazikika kwamadzimadzi ndikuletsa kulekana.

SCMC imagwiritsidwanso ntchito mu sauces, mavalidwe, ndi zokometsera monga ketchup, mayonesi, ndi mpiru, kuti zikhwime ndikuwongolera mawonekedwe awo.Amagwiritsidwa ntchito pazakudya za nyama monga soseji ndi ma meatballs, kuti apititse patsogolo zomwe zimamangiriza ndikuletsa kugwa pakuphika.Amagwiritsidwanso ntchito muzakudya zokhala ndi mafuta ochepa komanso ochepetsa ma calorie, m'malo mwa mafuta ndikuwongolera mawonekedwe.

SCMC nthawi zambiri imakhala yotetezeka kuti igwiritsidwe ntchito pazakudya ndi mabungwe olamulira padziko lonse lapansi, kuphatikiza US Food and Drug Administration (FDA) ndi European Food Safety Authority (EFSA).

Chitetezo cha SCMC mu Chakudya

SCMC yaphunziridwa mozama chifukwa cha chitetezo chake pazakudya, ndipo yapezeka kuti ndiyotetezeka kuti anthu adye pamlingo wogwiritsidwa ntchito muzakudya.The Joint FAO/WHO Expert Committee on Food Additives (JECFA) yakhazikitsa kudya kovomerezeka kwa tsiku ndi tsiku (ADI) kwa 0-25 mg/kg kulemera kwa thupi kwa SCMC, komwe kuli kuchuluka kwa SCMC komwe kumatha kudyedwa tsiku lililonse kwa moyo wonse popanda chilichonse. zotsatira zoyipa.

Kafukufuku wasonyeza kuti SCMC sipoizoni, carcinogenic, mutagenic, kapena teratogenic, ndipo sichimayambitsa vuto lililonse paubereki kapena chitukuko.Sizimapangidwa ndi thupi ndipo zimatulutsidwa mosasinthika mu ndowe, kotero sizimawunjikana m'thupi.

Komabe, anthu ena amatha kukhala ndi vuto la SCMC, zomwe zingayambitse zizindikiro monga ming'oma, kuyabwa, kutupa, komanso kupuma movutikira.Izi zimachitika kawirikawiri koma zimakhala zovuta nthawi zina.Ngati mukukumana ndi chimodzi mwazizindikirozi mutatha kudya chakudya chokhala ndi SCMC, inu kwa dokotala wanu nthawi yomweyo.

Zowopsa Zomwe Zingatheke za SCMC

Ngakhale SCMC nthawi zambiri imawonedwa ngati yotetezeka kuti anthu amwe, pali zoopsa zina zomwe zingagwirizane ndi kugwiritsidwa ntchito kwake.Chimodzi mwazinthu zomwe zimadetsa nkhawa kwambiri ndi momwe zimakhudzira kugaya chakudya.SCMC ndi ulusi wosungunuka, zomwe zikutanthauza kuti imatha kuyamwa madzi ndikupanga chinthu chonga gel m'matumbo.Izi zitha kuyambitsa vuto la kugaya chakudya monga kutupa, mpweya, ndi kutsekula m'mimba mwa anthu ena, makamaka ngati amamwa mochuluka.

Chiwopsezo china chomwe chingakhalepo ndi momwe zimakhudzira kuyamwa kwa michere.Chifukwa SCMC ikhoza kupanga gel-ngati gel m'matumbo, ikhoza kusokoneza kuyamwa kwa zakudya zina, makamaka mavitamini osungunuka ndi mafuta monga A, D, E, ndi K. Izi zikhoza kutsogolera kuperewera kwa zakudya m'kupita kwa nthawi, makamaka ngati amadyedwa mochuluka pafupipafupi.

Ndizofunikiranso kudziwa kuti kafukufuku wina wasonyeza kuti SCMC ikhoza kukhala ndi vuto pa thanzi lamatumbo.Kafukufuku yemwe adasindikizidwa mu nyuzipepala ya Nature Communications mu 2018 adapeza kuti SCMC ikhoza kusokoneza kuchuluka kwa mabakiteriya am'matumbo mu mbewa, zomwe zitha kubweretsa kutupa ndi zovuta zina zaumoyo.Ngakhale kafukufuku wochulukirapo akufunika kuti amvetsetse momwe SCMC imakhudzira thanzi lamatumbo mwa anthu, ili ndi gawo lodetsa nkhawa lomwe liyenera kuyang'aniridwa.

Mapeto

Sodium Carboxymethyl Cellulose ndi chowonjezera chazakudya chomwe chimawonedwa kuti ndi chotetezeka kuti anthu adye.Amagwiritsidwa ntchito makamaka ngati thickener, stabilizer, ndi emulsifier mu zakudya zosiyanasiyana, kuphatikizapo zophika, mkaka, zakumwa, ndi sauces.Ngakhale pali zoopsa zina zomwe zingagwirizane ndi kugwiritsidwa ntchito kwake, makamaka mochuluka, chitetezo chonse cha SCMC chakhazikitsidwa ndi mabungwe olamulira padziko lonse lapansi.

Monga chowonjezera chilichonse chazakudya, ndikofunikira kugwiritsa ntchito SCMC pang'onopang'ono komanso kudziwa zovuta zilizonse zomwe zingachitike.Ngati muli ndi nkhawa zokhudzana ndi kugwiritsa ntchito SCMC muzakudya, funsani dokotala wanu kapena katswiri wazakudya wolembetsa.
