Chikafu Chinowedzera Sodium Carboxymethyl Cellulose

Sodium carboxymethyl cellulose (CMC), inowanzonzi carboxymethyl cellulose (CMC) kana cellulose chingamu, inogonesa chikafu chekuwedzera chine huwandu hwakasiyana hwekushandisa muindasitiri yechikafu. Iyo inotorwa kubva ku cellulose, inowanzoitika inowanzoitika polysaccharide inowanikwa mumasero emadziro emiti. CMC inowanzoshandiswa seyakakora, stabilizer, emulsifier, uye mumiriri wekuchengeta mwando mune zvakasiyana zvigadzirwa zvekudya. Hunhu hwayo hwakasiyana hunoita kuti ive yakakosha mukugadzirwa kwezvinhu zvakawanda zvekudya.

Kemikari Mamiriro uye Zvivakwa

CMC inogadzirwa nekurapa cellulose ine sodium hydroxide uye monochloroacetic acid, zvichikonzera kutsiviwa kwemapoka ehydroxyl nemapoka ecarboxymethyl. Uku kugadziridzwa kunopa kunyungudika kwemvura kune cellulose molecule, ichibvumira kuti ishande nemazvo sekuwedzera kwechikafu. Iyo dhigirii yekutsiva (DS) inosarudza mwero wekutsiviwa kwemapoka ecarboxymethyl pane anhydroglucose unit mucheni ye cellulose, ichipesvedzera kunyungudika kwayo, viscosity, uye zvimwe zvinoshanda.

CMC iripo mumhando dzakasiyana siyana, kusanganisira hupfu, magranules, uye mhinduro, zvichienderana nekwakada kushandiswa. Haina hwema, haina kunaka, uye kazhinji ichena kusvika kure-chena muruvara. Iyo viscosity yeSCMC mhinduro inogona kugadziridzwa nezvinhu zvakasiyana senge kusungirirwa kwemhinduro, dhigirii rekutsiva, uye pH yepakati.

Mabasa muChikafu

Kukora: Rimwe remabasa ekutanga eCMC mune zvigadzirwa zvechikafu kuwedzera viscosity uye kupa mameseji. Inonatsiridza muromo wesoso, madhirezi, uye zvigadzirwa zvemukaka, zvichiita kuti zvive nyore uye zvinokwezva kuenderana. Muzvinhu zvakabikwa, CMC inobatsira kuvandudza hupfu hwekubata zvivakwa uye inopa chimiro kune yekupedzisira chigadzirwa.

Kudzikamisa: CMC inoita seyakagadzika nekudzivirira kupatsanurwa kwezvinhu mukugadzira chikafu. Inobatsira kumisa zvimedu zvimedu muzvinwiwa, semichero yemichero uye zvinwiwa zvinyoro, kudzivirira kudonha uye kuchengetedza kufanana kwechigadzirwa muhupenyu hwesherufu. Muaizikirimu uye madhiri akaomeswa nechando, CMC inhibits crystallization uye inovandudza kunaka kwechigadzirwa.

Emulsifying: Senge emulsifier, CMC inofambisa kuparadzirwa kwezvinhu zvisingagoneke, semafuta nemvura, mumasisitimu echikafu. Inodzikamisa emulsions, senge saladhi yekupfeka uye mayonnaise, nekugadzira firimu rinodzivirira rakatenderedza madonhwe, kudzivirira kubatana uye kuvimbisa kugadzikana kwenguva refu.

Kuchengeta Hunyoro: CMC ine hygroscopic zvivakwa, zvichireva kuti inogona kukwezva uye kuchengetedza hunyoro. Muzvinhu zvakabikwa, zvinobatsira kurebesa kutsva uye hupenyu hwesherufu nekudzikisira kudzika uye kuchengetedza hunyoro. Pamusoro pezvo, muzvigadzirwa zvenyama nehuku, CMC inogona kuwedzera juiciness uye kudzivirira kurasikirwa nehunyoro panguva yekubika nekuchengetedza.

Firimu-Kugadzira: CMC inogona kuumba anochinjika uye akajeka mafirimu kana akaomeswa, ichiita kuti ive yakakodzera kune maapplication akadai semachira anodyiwa uye encapsulation yezvikafu zvinongedzo. Aya mafirimu anopa chipingamupinyi pakurasikirwa nekunyorova, okisijeni, uye zvimwe zvinhu zvekunze, zvichiwedzera hupenyu hwesherufu yezvigadzirwa zvinoparara.

Applications

CMC inowana kushandiswa kwakapararira muzvigadzirwa zvekudya zvakasiyana mumapoka akasiyana:

Bakery Products: Chingwa, makeke, makeke, uye mabhisikiti anobatsirwa kubva kuCMC kugona kugadzirisa mabatiro ehupfu, magadzirirwo, uye hupenyu hwesherufu.
Dairy uye Desserts: Ice cream, yogati, custards, uye puddings anoshandisa SCMC pakudzikamisa uye kukora zvivakwa.
Zvinwiwa: Zvinwiwa zvinyoro, zvinwiwa zvemichero, uye zvinwiwa zvinodhaka zvinoshandisa CMC kudzivirira kupatsanurwa kwechikamu uye kuchengetedza kuenderana kwechigadzirwa.
Sauces uye Kupfeka: Salad dressings, gravies, sosi, uye condiments vanovimba CMC nokuda viscosity kudzora uye kugadzikana.
Nyama uye Zvigadzirwa zvehuku: Nyama dzakagadzirwa, masoseji, uye nyama analogs anoshandisa CMC kuwedzera hunyoro kuchengetedza uye magadzirirwo.
Confections: Candies, gummies, uye marshmallows anobatsirwa nebasa reCMC mukugadziriswa kwemavara uye kudzora mwando.

Regulatory Status uye Kuchengetedza
CMC inotenderwa kushandiswa sechikafu chekuwedzera nevakuru vane hutongi seUS Food and Drug Administration (FDA) neEuropean Food Safety Authority (EFSA). Inowanzo zivikanwa seyakachengeteka (GRAS) kana ichishandiswa zvinoenderana nemaitiro akanaka ekugadzira uye mukati memiganhu yakatarwa. Nekudaro, kunyanyisa kunwa kweSCMC kunogona kukonzera kusagadzikana kwemudumbu muvanhu vane hanya.

sodium carboxymethyl cellulose chinhu chakakosha chekuwedzera chikafu chinopa kunaka, kugadzikana, uye kushanda kwezvizhinji zvigadzirwa zvekudya. Basa rayo rakasiyana-siyana seyakakora, stabilizer, emulsifier, uye mumiriri wekuchengetedza hunyoro inoita kuti ive yakakosha mukugadzira chikafu chemazuva ano, ichigonesa kugadzirwa kwemhando dzakasiyana dzezvikafu zvine hunhu hunodiwa uye hupenyu hwakareba hwesherufu.
