Sodium carboxymethyl cellulose muzakudya

Mawu Oyamba

Sodium carboxymethyl cellulose (CMC) ndi chowonjezera chogwiritsidwa ntchito kwambiri chomwe chimagwiritsidwa ntchito kukonza mawonekedwe, kukhazikika, komanso moyo wa alumali wazakudya zosiyanasiyana. CMC ndi ufa woyera, wopanda fungo, wopanda kukoma womwe umachokera ku cellulose, chigawo chachikulu cha makoma a maselo a zomera. Ndi polysaccharide, kutanthauza kuti imapangidwa ndi mamolekyu ambiri a shuga olumikizidwa palimodzi. CMC imagwiritsidwa ntchito muzakudya zosiyanasiyana, kuphatikiza ayisikilimu, sosi, mavalidwe, ndi zinthu zophika.

Mbiri

CMC idapangidwa koyamba kumayambiriro kwa zaka za m'ma 1900 ndi katswiri wa zamankhwala waku Germany, Dr. Karl Schardinger. Anapeza kuti popereka mankhwala a cellulose ndi sodium hydroxide ndi monochloroacetic acid, amatha kupanga chinthu chatsopano chomwe chimasungunuka m'madzi kuposa cellulose. Gulu latsopanoli linatchedwa carboxymethyl cellulose, kapena CMC.

M'zaka za m'ma 1950, CMC idagwiritsidwa ntchito koyamba ngati chowonjezera cha chakudya. Anagwiritsidwa ntchito kulimbitsa ndi kukhazikika masukisi, mavalidwe, ndi zakudya zina. Kuyambira pamenepo, CMC yakhala chowonjezera chodziwika bwino chazakudya chifukwa chakutha kukonza mawonekedwe, kukhazikika, komanso moyo wa alumali wazakudya.

Chemistry

CMC ndi polysaccharide, kutanthauza kuti imapangidwa ndi mamolekyu ambiri a shuga olumikizidwa palimodzi. Chigawo chachikulu cha CMC ndi cellulose, womwe ndi unyolo wautali wa mamolekyu a glucose. Ma cellulose akathandizidwa ndi kuphatikiza kwa sodium hydroxide ndi monochloroacetic acid, amapanga carboxymethyl cellulose. Njira imeneyi imadziwika kuti carboxymethylation.

CMC ndi ufa woyera, wopanda fungo, wopanda kukoma womwe umasungunuka m'madzi ozizira komanso otentha. Ndizinthu zopanda poizoni, zopanda allergenic, komanso zosakwiyitsa zomwe zimakhala zotetezeka kuti anthu azidya.

Ntchito

CMC imagwiritsidwa ntchito pazinthu zosiyanasiyana zazakudya kuti zisinthe mawonekedwe, kukhazikika, komanso moyo wa alumali. Amagwiritsidwa ntchito ngati thickening wothandizira kuti zakudya zizikhala zofewa komanso kuti zikhazikike kuti zisapatuke kapena kuwonongeka. CMC amagwiritsidwanso ntchito ngati emulsifier kuthandiza mafuta ndi madzi kusakaniza pamodzi.

Kuphatikiza apo, CMC imagwiritsidwa ntchito poletsa mapangidwe a ayezi muzakudya zoziziritsa kukhosi, monga ayisikilimu. Amagwiritsidwanso ntchito kuwongolera kapangidwe kazinthu zowotcha, monga makeke ndi makeke.

Malamulo

CMC imayendetsedwa ndi Food and Drug Administration (FDA) ku United States. A FDA akhazikitsa kuchuluka kwa kugwiritsidwa ntchito kwa CMC muzakudya. Mlingo waukulu wogwiritsidwa ntchito ndi 0.5% polemera.

Mapeto

Sodium carboxymethyl cellulose (CMC) ndi chowonjezera chogwiritsidwa ntchito kwambiri chomwe chimagwiritsidwa ntchito kukonza mawonekedwe, kukhazikika, komanso moyo wa alumali wazakudya zosiyanasiyana. CMC ndi ufa woyera, wopanda fungo, wopanda kukoma womwe umachokera ku cellulose, chigawo chachikulu cha makoma a zomera. Ndi polysaccharide, kutanthauza kuti imapangidwa ndi mamolekyu ambiri a shuga olumikizidwa palimodzi. CMC imagwiritsidwa ntchito ngati thickening agent, emulsifier, komanso kupewa mapangidwe a ice crystal muzakudya zoziziritsa kukhosi. Imayendetsedwa ndi FDA ku United States, ndi mlingo waukulu wogwiritsira ntchito 0.5% kulemera kwake.
