Carboxymethyl cellulose (CMC) ndi polima wosungunuka m'madzi womwe umagwiritsidwa ntchito mosiyanasiyana pazakudya. Ndi chowonjezera cha chakudya chomwe chimapangidwa kuchokera ku cellulose, yomwe imachokera ku nkhuni, thonje, kapena zomera zina. CMC imagwiritsidwa ntchito kwambiri m'makampani azakudya monga thickener, stabilizer, ndi emulsifier chifukwa cha mawonekedwe ake apadera. M'nkhaniyi, tikambirana za katundu, ntchito, ndi ubwino wa CMC chakudya kalasi.

Katundu wa CMC Food Grade

CMC ndi ufa wamitundu yoyera mpaka wa kirimu wopanda kukoma, wopanda fungo, komanso kukoma kowawa pang'ono. Imasungunuka m'madzi ndipo imapanga yankho lomveka bwino, lowoneka bwino likasungunuka m'madzi. CMC ili ndi kulemera kwakukulu kwa maselo ndipo imapangidwa ndi unyolo wautali wa ma cellulose. Maunyolowa ali ndi magulu a carboxymethyl omwe amawaphatikiza, omwe amapatsa CMC mawonekedwe ake apadera.

Chimodzi mwazinthu zofunika kwambiri za CMC ndikutha kupanga gel osakaniza ndi madzi. Mphamvu ya gel ya CMC imadalira kuchuluka kwa yankho ndi kulemera kwa ma polima. CMC ilinso ndi kukhuthala kwakukulu, komwe kumapangitsa kuti ikhale yogwira ntchito yowonjezereka. Kukhuthala kwa mayankho a CMC kumatha kusinthidwa posintha kuchuluka kwa yankho.

Chinthu china chofunikira cha CMC ndikutha kupanga ma emulsions okhazikika. CMC imatha kukhazikika emulsions yamafuta m'madzi mwa kupanga filimu yoteteza kuzungulira madontho amafuta. Firimuyi imalepheretsa kuti madonthowo asagwirizane ndipo amathandizira kukhazikika kwa emulsion.

Mapulogalamu a CMC Food Grade

CMC imagwiritsidwa ntchito pazakudya zosiyanasiyana chifukwa cha mawonekedwe ake apadera. Zina mwazomwe zimagwiritsidwa ntchito kwambiri pagulu lazakudya za CMC ndi monga:

1. Thickener: CMC imagwiritsidwa ntchito ngati chowonjezera pazakudya monga sosi, mavalidwe, ndi ma gravies. Zimathandizira kuwongolera kapangidwe kake ndi kamvekedwe ka zinthu izi powonjezera kukhuthala kwawo.
2. Stabilizer: CMC imagwiritsidwa ntchito ngati stabilizer mu ayisikilimu ndi zowonda zina zachisanu. Zimathandiza kupewa mapangidwe a ayezi makhiristo ndi bwino kusalala kwa mankhwala omaliza.
3. Emulsifier: CMC imagwiritsidwa ntchito ngati emulsifier muzinthu monga mavalidwe a saladi ndi mayonesi. Zimathandizira kukhazikika kwa emulsion yamafuta m'madzi ndikuletsa kupatukana kwa zinthuzo.
4. Binder: CMC imagwiritsidwa ntchito ngati chomangira pazinthu monga nyama, zophika, ndi tchizi. Zimathandizira kukonza kapangidwe kake komanso kumangirira kwazinthu izi.
5. Filimu-yakale: CMC imagwiritsidwa ntchito ngati filimu-yoyamba muzinthu monga magalasi ophika mkate ndi zokutira. Zimathandiza kukonza maonekedwe ndi moyo wa alumali wazinthuzi.

Ubwino wa CMC Food Grade

1. Zotsika mtengo: CMC ndi chakudya chotsika mtengo chomwe chimagwiritsidwa ntchito kwambiri m'makampani azakudya. Ndiwotsika mtengo poyerekeza ndi zokhuthala zina, zolimbitsa thupi, ndi emulsifiers.
2. Otetezeka: CMC imawonedwa kuti ndi yotetezeka kuti igwiritsidwe ntchito ndi mabungwe olamulira monga Food and Drug Administration (FDA) ndi European Food Safety Authority (EFSA). Zayesedwa kwambiri kuti zitetezeke ndipo zavomerezedwa kuti zigwiritsidwe ntchito muzakudya.
3. Zosiyanasiyana: CMC ndi chowonjezera chazakudya chomwe chitha kugwiritsidwa ntchito pazakudya zosiyanasiyana. Itha kugwiritsidwa ntchito ngati thickener, stabilizer, emulsifier, binder, ndi filimu-yakale, ndikupangitsa kuti ikhale yothandiza pazakudya zambiri.
4. Zopanda Poizoni: CMC ndi chakudya chopanda poizoni chomwe chili chotetezeka kuti munthu amwe. Sichimatengedwa ndi thupi ndipo chimadutsa m'matumbo osasinthika.
