Sodium carboxymethyl cellulose ndi nambala

Mawu Oyamba

Sodium carboxymethyl cellulose (CMC) ndi chowonjezera chogwiritsidwa ntchito kwambiri ndi E466. Ndi ufa woyera, wopanda fungo, wopanda kukoma womwe umagwiritsidwa ntchito ngati thickener ndi stabilizer mu zakudya zambiri. CMC ndi yochokera ku cellulose, polysaccharide yopezeka mwachilengedwe yomwe imapezeka muzomera. Amapangidwa ndikuchita cellulose ndi sodium hydroxide ndi monochloroacetic acid. CMC imagwiritsidwa ntchito muzakudya zosiyanasiyana, kuphatikiza ayisikilimu, mavalidwe a saladi, sosi, ndi zinthu zophika. Amagwiritsidwanso ntchito mu mankhwala, zodzoladzola, ndi zotsukira.

Kapangidwe ka Chemical

Sodium carboxymethyl cellulose ndi anionic polysaccharide yopangidwa ndi mayunitsi obwereza a D-glucose ndi D-mannose. Mapangidwe a mankhwala a CMC akuwonetsedwa mu Chithunzi 1. Magawo obwerezabwereza amalumikizidwa pamodzi ndi ma glycosidic bond. Magulu a carboxymethyl amalumikizidwa ndi magulu a hydroxyl a glucose ndi mannose unit. Izi zimapangitsa molekyu kukhala ndi mlandu woyipa, womwe umayambitsa zinthu zake zosungunuka m'madzi.

Chithunzi 1. Mapangidwe a mankhwala a sodium carboxymethyl cellulose

Katundu

Sodium carboxymethyl cellulose ili ndi zinthu zingapo zapadera zomwe zimapangitsa kuti zikhale zothandiza pazakudya. Ndi chinthu chopanda poizoni, chosakwiyitsa, komanso chopanda allergenic. Ndiwowonjezera kwambiri komanso wokhazikika, womwe umapangitsa kuti ukhale wabwino kugwiritsa ntchito sosi ndi mavalidwe. CMC ndi emulsifier yogwira mtima, yomwe imathandiza kuti mafuta ndi madzi asalekanitse. Zimalimbananso ndi kutentha, asidi, ndi alkali, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pazakudya zosiyanasiyana.

Ntchito

Sodium carboxymethyl cellulose amagwiritsidwa ntchito muzakudya zosiyanasiyana, kuphatikiza ayisikilimu, mavalidwe a saladi, sosi, ndi zinthu zophika. Amagwiritsidwanso ntchito mu mankhwala, zodzoladzola, ndi zotsukira. Pazakudya, CMC imagwiritsidwa ntchito ngati thickener, stabilizer, ndi emulsifier. Zimathandizira kuti zosakaniza zisalekanitse ndikuwongolera mawonekedwe ndi kusasinthika kwa chinthucho. Pazamankhwala, CMC imagwiritsidwa ntchito ngati chomangira komanso chosokoneza. Mu zodzoladzola, amagwiritsidwa ntchito ngati thickener ndi stabilizer. Mu detergents, amagwiritsidwa ntchito ngati dispersant ndi emulsifier.

Chitetezo

Sodium carboxymethyl cellulose imadziwika kuti ndi yotetezeka (GRAS) ndi US Food and Drug Administration (FDA). Imavomerezedwanso kuti igwiritsidwe ntchito muzakudya ku European Union. CMC ndi yopanda poizoni komanso si allergenic, ndipo yakhala ikugwiritsidwa ntchito muzakudya kwazaka zopitilira 50. Komabe, ndikofunikira kudziwa kuti CMC imatha kuyamwa madzi, zomwe zingayambitse kutupa ndikukhala viscous. Izi zingayambitse kutsamwitsidwa ngati mankhwalawo sagwiritsidwa ntchito moyenera.
