Sodium carboxymethyl cellulose na nri

Okwu mmalite

Sodium carboxymethyl cellulose (CMC) bụ ihe mgbakwunye nri a na-ejikarị eme ihe nke a na-eji mee ka udidi, nkwụsi ike, na ndụ nchekwa nke ngwaahịa nri dị iche iche. CMC bụ ọcha, enweghị isi, ntụ ntụ na-enweghị ụtọ nke sitere na cellulose, bụ isi akụkụ nke mgbidi cell osisi. Ọ bụ polysaccharide, nke pụtara na ọ nwere ọtụtụ mkpụrụ ndụ shuga jikọtara ọnụ. A na-eji CMC eme ihe n'ụdị nri dị iche iche, gụnyere ice cream, sauces, uwe, na ngwaahịa esi nri.

Akụkọ ihe mere eme

Ebu ụzọ mepụta CMC na mmalite 1900 site n'aka onye German chemist, Dr. Karl Schardinger. Ọ chọpụtara na site n'ịgwọ cellulose na ngwakọta nke sodium hydroxide na monochloroacetic acid, ọ nwere ike ịmepụta ihe ọhụrụ nke na-agbaze na mmiri karịa cellulose. Akpọrọ aha ogige ọhụrụ a carboxymethyl cellulose, ma ọ bụ CMC.

Na 1950s, CMC bu ụzọ jiri dị ka mgbakwunye nri. A na-eji ya mee ka ọ sie ike ma mee ka nri, akwa na ngwaahịa nri ndị ọzọ kwụsie ike. Kemgbe ahụ, CMC abụrụla ihe mgbakwunye nri na-ewu ewu n'ihi ikike ya imeziwanye udidi, nkwụsi ike, na ndụ nchekwa nke ngwaahịa nri.

Chemistry

CMC bụ polysaccharide, nke pụtara na ọ bụ ọtụtụ mkpụrụ ndụ shuga jikọtara ọnụ. Akụkụ bụ isi nke CMC bụ cellulose, nke bụ ogologo agbụ nke molekul glucose. Mgbe a na-agwọ cellulose na ngwakọta nke sodium hydroxide na monochloroacetic acid, ọ na-etolite carboxymethyl cellulose. A maara usoro a dị ka carboxymethylation.

CMC bụ ọcha, enweghị isi, ntụ ntụ na-enweghị ụtọ nke na-agbaze na mmiri oyi na mmiri ọkụ. Ọ bụ ihe na-adịghị egbu egbu, nke na-adịghị egbu egbu, na nke na-adịghị ewe iwe nke dị mma maka oriri mmadụ.

Ọrụ

A na-eji CMC n'ụdị ngwaahịa nri dị iche iche iji meziwanye ọdịdị ha, nkwụsi ike, na ndụ nchekwa. A na-eji ya dị ka ihe na-akpụ akpụ iji nye ngwaahịa nri ụdị ude na-eme ka ọ kwụsie ike ka ha ghara ikewapụ ma ọ bụ mebie ya. A na-ejikwa CMC dị ka emulsifier iji nyere mmanụ na mmiri aka ịgwakọta ọnụ.

Na mgbakwunye, a na-eji CMC egbochi imepụta kristal ice na desserts oyi kpọnwụrụ, dị ka ice cream. A na-ejikwa ya na-emeziwanye ọdịdị nke ihe ndị a na-eme achịcha, dị ka achịcha na kuki.

Iwu

Ndị nchịkwa nri na ọgwụ ọjọọ (FDA) na-achịkwa CMC na United States. FDA ewepụtala oke ojiji maka CMC na ngwaahịa nri. Oke kachasị nke ojiji bụ 0.5% site na ibu.

Mmechi

Sodium carboxymethyl cellulose (CMC) bụ ihe mgbakwunye nri a na-ejikarị eme ihe nke a na-eji mee ka udidi, nkwụsi ike, na ndụ nchekwa nke ngwaahịa nri dị iche iche. CMC bụ ọcha, enweghị isi, ntụ ntụ na-enweghị ụtọ nke sitere na cellulose, bụ isi akụkụ nke mgbidi cell osisi. Ọ bụ polysaccharide, nke pụtara na ọ nwere ọtụtụ mkpụrụ ndụ shuga jikọtara ọnụ. A na-eji CMC eme ihe dị ka ihe na-eme ka ọ sie ike, emulsifier, yana igbochi nguzobe kristal na desserts oyi kpọnwụrụ. Ọ bụ FDA na United States na-ahazi ya, yana oke ojiji nke 0.5% site na ịdị arọ.
