CMC (carboxymethyl cellulose) ndi thickener, stabilizer ndi emulsifier amagwiritsidwa ntchito kwambiri. Ndi mankhwala opangidwa ndi cellulose opangidwa ndi mankhwala, omwe nthawi zambiri amachokera ku ulusi wa zomera monga thonje kapena zamkati zamatabwa. CMC imagwiritsidwa ntchito kwambiri m'makampani azakudya chifukwa imatha kusintha mawonekedwe, kukoma ndi kukhazikika kwa chakudya.
1. Malamulo ndi ziphaso
Malamulo apadziko lonse lapansi
CMC yavomerezedwa kuti igwiritsidwe ntchito ngati chowonjezera chazakudya ndi mabungwe ambiri oteteza zakudya padziko lonse lapansi. Mwachitsanzo, bungwe la US Food and Drug Administration (FDA) limachilemba ngati chinthu Chodziwika Monga Chotetezedwa (GRAS), zomwe zikutanthauza kuti CMC imawonedwa ngati yopanda vuto m'thupi la munthu pakagwiritsidwe ntchito pafupipafupi. European Food Safety Authority (EFSA) imavomerezanso kugwiritsidwa ntchito kwake ngati chowonjezera cha chakudya pansi pa nambala E466.
Malamulo achi China
Ku China, CMC ndiwowonjezeranso chakudya chovomerezeka. Muyezo wapadziko lonse wachitetezo chazakudya "Standard for Use of Food Additives" (GB 2760) umafotokoza momveka bwino kugwiritsa ntchito CMC pazakudya zosiyanasiyana. Mwachitsanzo, amagwiritsidwa ntchito mu zakumwa, mkaka, zophikidwa ndi zokometsera, ndipo kagwiritsidwe kake kamakhala kotetezedwa.
2. Maphunziro a Toxicology
Zoyeserera zanyama
Zoyeserera zingapo zanyama zawonetsa kuti CMC siyambitsa zochitika zapoizoni pamilingo wamba. Mwachitsanzo, kudyetsa kwanthawi yayitali kwa chakudya chokhala ndi CMC sikunapangitse zotupa zachilendo mu nyama. Kudya kwambiri kungayambitse vuto linalake la m'mimba, koma izi ndizosowa pogwiritsira ntchito tsiku ndi tsiku.
Maphunziro a anthu
Kafukufuku wochepa wa anthu awonetsa kuti CMC ilibe vuto lililonse pazakudya zabwinobwino. Nthawi zina, kumwa kwambiri kungayambitse kusapeza bwino m'mimba, monga kutupa kapena kutsekula m'mimba, koma zizindikirozi nthawi zambiri zimakhala zosakhalitsa ndipo sizingawononge thupi kwa nthawi yaitali.
3. Ntchito ndi ntchito
CMC ili ndi madzi abwino kusungunuka komanso kukhuthala, zomwe zimapangitsa kuti zigwiritsidwe ntchito kwambiri pamakampani azakudya. Mwachitsanzo:
Zakumwa: CMC imatha kusintha kukoma kwa zakumwa ndikupangitsa kuti zikhale zosalala.
Zamkaka: Mu yogati ndi ayisikilimu, CMC imatha kuletsa kulekanitsa kwamadzi ndikuwongolera kukhazikika kwazinthu.
Zophika buledi: CMC imatha kusintha mawonekedwe a mtanda ndikuwonjezera kukoma kwazinthu.
Zokometsera: CMC imatha kuthandizira ma sosi kuti azikhala ndi mawonekedwe ofanana komanso kupewa kukhazikika.
4. Matupi awo sagwirizana ndi zotsatira zake
Thupi lawo siligwirizana
Ngakhale CMC imadziwika kuti ndi yotetezeka, anthu ochepa amatha kukhala ndi vuto lawo. Izi sizichitikachitika kawirikawiri ndipo zizindikiro zake zimakhala zotupa, kuyabwa, komanso kupuma movutikira. Ngati zizindikirozi zichitika, siyani kudya ndipo funsani thandizo lachipatala mwamsanga.
Zotsatira zake
Kwa anthu ambiri, kudya pang'ono kwa CMC sikumayambitsa mavuto. Komabe, kudya kwambiri kungayambitse kusapeza bwino m'mimba monga kutupa, kutsegula m'mimba, kapena kudzimbidwa. Zotsatira zoyipazi nthawi zambiri zimakhala zosakhalitsa ndipo zimakhazikika paokha pambuyo pochepetsa kudya.
CMC ndi yotetezeka ngati chowonjezera cha chakudya. Kugwiritsa ntchito kwake kwakukulu komanso kafukufuku wambiri wawonetsa kuti CMC sichivulaza thanzi la anthu malinga ndi kugwiritsidwa ntchito mololedwa ndi malamulo. Komabe, monga zowonjezera zakudya zonse, kugwiritsa ntchito moyenera ndikofunikira. Ogula akamasankha chakudya, ayenera kulabadira mndandanda wazinthuzo kuti amvetsetse mtundu ndi kuchuluka kwa zowonjezera zomwe zili. Ngati muli ndi nkhawa, ndi bwino kukaonana ndi akatswiri azakudya kapena azachipatala.
