Carboxymethyl cellulose (sodium carboxyme thyl cellulose, CMC) wani carboxymethylated samu daga cellulose, kuma aka sani da cellulose danko, kuma shi ne mafi muhimmanci ionic cellulose danko.
CMC galibi wani fili ne na polymer anionic wanda aka shirya ta hanyar amsa cellulose na halitta tare da caustic alkali da monochloroacetic acid. Nauyin kwayoyin halitta na fili ya bambanta daga dubu da yawa zuwa miliyan daya.
CMC na cikin gyare-gyaren cellulose na halitta, kuma Hukumar Abinci da Aikin Noma ta Majalisar Dinkin Duniya (FAO) da Hukumar Lafiya ta Duniya (WHO) sun kira shi a hukumance "cellulose da aka gyara". Hanyar hada sinadarin sodium carboxymethyl cellulose ta Jamus E. Jansen ne ya ƙirƙira a shekarar 1918, kuma an ba da haƙƙin mallaka a cikin 1921 kuma ya zama sananne ga duniya, sannan aka yi ciniki da shi a Turai.
Ana amfani da CMC sosai a cikin man fetur, ilimin ƙasa, sinadarai na yau da kullun, abinci, magunguna da sauran masana'antu, waɗanda aka sani da "monosodium glutamate masana'antu".
※Kaddarorin tsarin CMC
CMC fari ne ko haske rawaya foda, granular ko fibrous m. Wani sinadari ne na macromolecular wanda zai iya sha ruwa ya kumbura. Lokacin da ya kumbura cikin ruwa, zai iya samar da manne mai haske. Matsakaicin pH na dakatarwar ruwa shine 6.5-8.5. Abun ba shi da narkewa a cikin kaushi na halitta kamar ethanol, ether, acetone da chloroform.
CMC mai ƙarfi yana da ɗan kwanciyar hankali ga haske da zafin jiki, kuma ana iya adana shi na dogon lokaci a cikin busasshiyar wuri. CMC wani nau'i ne na ether cellulose, yawanci ana yin shi da gajeren auduga linters ( abun ciki na cellulose har zuwa 98%) ko ɓangaren litattafan almara na itace, wanda aka bi da shi tare da sodium hydroxide sannan kuma ya amsa tare da sodium monochloroacetate, nauyin kwayoyin halitta na fili shine 6400 (± 1000). Yawancin hanyoyin shirye-shirye guda biyu ne: hanyar ruwa-kwal da hanyar ƙarfi. Akwai kuma wasu filayen shuka da ake amfani da su don shirya CMC.
※Siffofin da aikace-aikace
CMC ba kawai mai kyau emulsification stabilizer da thickener a cikin aikace-aikace na abinci, amma kuma yana da kyau kwarai daskarewa da narkewa da kwanciyar hankali, kuma zai iya inganta dandano na samfurin da kuma tsawanta lokacin ajiya.
A cikin 1974, Hukumar Abinci da Aikin Noma ta Majalisar Dinkin Duniya (FAO) da Hukumar Lafiya ta Duniya (WHO) sun amince da amfani da CMC mai tsafta a cikin abinci bayan tsauraran bincike da gwaje-gwajen halittu da guba. Amintaccen ci (ADI) na ma'aunin duniya shine 25mg/kg nauyin jiki/rana.
※Thickening da emulsion kwanciyar hankali
Cin CMC na iya kwaikwaya da daidaita abubuwan sha masu ɗauke da mai da furotin. Wannan shi ne saboda CMC ya zama colloid mai ƙarfi a fili bayan an narkar da shi a cikin ruwa, kuma ƙwayoyin sunadaran suna zama barbashi tare da caji iri ɗaya a ƙarƙashin kariya na colloidal membrane, wanda zai iya sa kwayoyin sunadaran suna cikin kwanciyar hankali. Yana da wani sakamako na emulsifying, don haka zai iya rage tashin hankali tsakanin mai da ruwa a lokaci guda, don haka mai zai iya zama cikakke emulsified.
CMC na iya inganta kwanciyar hankali na samfurin, saboda lokacin da ƙimar pH na samfurin ya ɓace daga ma'anar isoelectric na furotin, sodium carboxymethyl cellulose zai iya samar da tsari mai hade tare da furotin, wanda zai iya inganta kwanciyar hankali na samfurin.
※Ƙara girma
Yin amfani da CMC a cikin kirim na ice cream na iya kara girman girman girman ice cream, inganta saurin narkewa, ba da siffar mai kyau da dandano, da kuma sarrafa girman da girma na lu'ulu'u na kankara a lokacin sufuri da ajiya. Adadin da aka yi amfani da shi shine 0.5% na jimlar Ƙididdigar Ƙididdigar.
Wannan saboda CMC yana da kyakkyawar riƙewar ruwa da tarwatsewa, kuma a zahiri yana haɗa nau'ikan furotin, fat globules, da kwayoyin ruwa a cikin colloid don samar da tsari mai daidaituwa da kwanciyar hankali.
※Hydrophilicity da Rehydration
Wannan kayan aiki na CMC ana amfani dashi gabaɗaya wajen samar da burodi, wanda zai iya sanya saƙar zuma ta zama daidai, ƙara ƙara, rage ɗigon ruwa, kuma yana da tasirin adana zafi da sabo; noodles da aka ƙara tare da CMC suna da ƙarfin riƙe ruwa mai kyau, juriya na dafa abinci, da dandano mai kyau.
An ƙaddara wannan ta hanyar tsarin kwayoyin halitta na CMC, wanda shine samfurin cellulose kuma yana da adadi mai yawa na kungiyoyin hydrophilic a cikin sarkar kwayoyin: -OH kungiyar, -COONa kungiyar, don haka CMC yana da mafi kyawun hydrophilicity fiye da cellulose da ikon rike ruwa.
※ Gelation
Thixotropic CMC yana nufin cewa sarƙoƙi na macromolecular suna da ƙayyadaddun hulɗar hulɗar juna kuma sukan haifar da tsari mai girma uku. Bayan an kafa tsari mai girma uku, dankon maganin yana ƙaruwa, kuma bayan an karya tsarin mai girma uku, danko yana raguwa. Abin mamaki na thixotropy shine cewa canji na danko na fili ya dogara da lokaci.
Thixotropic CMC yana taka muhimmiyar rawa a cikin tsarin gelling kuma ana iya amfani dashi don yin jelly, jam da sauran abinci.
Ana iya amfani da shi azaman mai bayyanawa, mai daidaita kumfa, ƙara jin daɗin baki
Ana iya amfani da CMC a cikin samar da ruwan inabi don yin dandano mai laushi da wadata tare da dogon lokaci; ana iya amfani da shi azaman mai tabbatar da kumfa a cikin samar da giya don yin kumfa mai wadata da tsayi da kuma inganta dandano.
CMC wani nau'i ne na polyelectrolyte, wanda zai iya shiga cikin halayen daban-daban a cikin ruwan inabi don kula da ma'auni na jikin ruwan inabi. A lokaci guda kuma, yana haɗuwa tare da lu'ulu'u waɗanda suka kafa, canza tsarin lu'ulu'u, canza yanayin wanzuwar lu'ulu'u a cikin giya, da haifar da hazo. Tarin abubuwa.
