Sodium carboxymethyl cellulose e nọmba

Okwu mmalite

Sodium carboxymethyl cellulose (CMC) bụ ihe mgbakwunye nri a na-ejikarị nwere nọmba E466. Ọ bụ ihe na-acha ọcha, enweghị isi, ntụ ntụ na-enweghị ụtọ nke a na-eji dị ka ihe na-eme ka ọ dị arọ na ihe nkwụnye n'ọtụtụ ngwaahịa nri. CMC bụ ihe sitere na cellulose, polysaccharide na-emekarị nke a na-ahụ na osisi. A na-emepụta ya site na mmeghachi omume cellulose na sodium hydroxide na monochloroacetic acid. A na-eji CMC eme ihe n'ụdị nri dị iche iche, gụnyere ice cream, mgbakwasa salad, sauces, na ngwaahịa esi nri. A na-ejikwa ya na ọgwụ, ihe ịchọ mma, na ncha.

Ọdịdị Chemical

Sodium carboxymethyl cellulose bụ anionic polysaccharide nke mejupụtara nkeji ugboro nke D-glucose na D-mannose. E gosipụtara usoro kemịkalụ nke CMC na eserese 1. A na-ejikọta nkeji ugboro ugboro site na njikọ glycosidic ọnụ. Otu carboxymethyl jikọtara ya na otu hydroxyl nke glucose na nkeji mannose. Nke a na-enye molekul ahụ ụgwọ na-adịghị mma, nke na-ahụ maka ihe ndị nwere ike ime mmiri.
