Carboxymethyl Cellulose (Chingerezi: Carboxymethyl Cellulose, CMC mwachidule) ndi chowonjezera chazakudya chomwe chimagwiritsidwa ntchito kwambiri, ndipo mchere wake wa sodium (sodium carboxymethyl cellulose) umagwiritsidwa ntchito nthawi zambiri ngati chowonjezera komanso phala.
Carboxymethyl cellulose amatchedwa mafakitale monosodium glutamate, omwe amagwiritsidwa ntchito kwambiri popanga mafakitale ndipo amabweretsa phindu lalikulu pamagawo osiyanasiyana opanga.Carboxymethyl cellulose ndi zinthu zaufa, zopanda poizoni, koma ndizosavuta kusungunuka m'madzi.Imasungunuka m'madzi ozizira ndi madzi otentha, koma imasungunuka mu zosungunulira za organic.Idzakhala madzi a viscous pambuyo pa kusungunuka, koma kukhuthala kumasiyana chifukwa cha kutentha ndi kugwa.Chifukwa cha katundu wake wapadera, pali zofunikira zambiri zapadera posungira ndi kuyendetsa.
Thupi ndi mankhwala katundu
Carboxymethyl cellulose ndi chinthu choyera kapena chopepuka chachikasu, chosanunkha, chosakoma, ma hygroscopic granules, ufa kapena ulusi wabwino.
※Pkubwezera
Carboxymethylcellulose amapangidwa ndi maziko-catalyzed reaction ya cellulose ndi chloroacetic acid.Magulu a polar (organic acid) a carboxyl amapangitsa cellulose kusungunuka komanso kuchitapo kanthu pamankhwala.Pambuyo pochita koyamba, osakanizawo adapereka pafupifupi 60% CMC kuphatikiza 40% mchere (sodium chloride ndi sodium glycolate).Chogulitsacho ndi chotchedwa CMC yamakampani opanga zotsukira.Mcherewu umachotsedwa pogwiritsa ntchito njira ina yoyeretsera kuti apange CMC yoyera kuti igwiritsidwe ntchito muzakudya, mankhwala ndi dentifrices (mankhwala otsukira mano).Magiredi apakatikati a "semi-purified" amapangidwanso, omwe nthawi zambiri amagwiritsidwa ntchito pamapepala monga kubwezeretsanso zolemba zakale.Zomwe zimagwira ntchito za CMC zimadalira kuchuluka kwa m'malo mwa cellulose (ndiko kuti, ndi magulu angati a hydroxyl omwe amatenga nawo gawo polowa m'malo), komanso kutalika kwa unyolo wa cellulose msana ndi kuchuluka kwa kuphatikizika kwa cellulose msana. .Carboxymethyl m'malo.
※Akupempha
Carboxymethylcellulose amagwiritsidwa ntchito muzakudya ngati viscosity modifier kapena thickener pansi pa E466 kapena E469 (by enzymatic hydrolysis) ndikukhazikitsa ma emulsions pazinthu zosiyanasiyana, kuphatikiza ayisikilimu.Komanso ndi gawo la zinthu zambiri zomwe si za chakudya monga mankhwala otsukira mano, mankhwala ofewetsa thukuta, mapiritsi a zakudya, penti yochokera m'madzi, zotsukira, zopangira nsalu, zopakanso zotenthetsera ndi zina zamapepala.Amagwiritsidwa ntchito makamaka chifukwa ndi makulidwe apamwamba, alibe poizoni ndipo nthawi zambiri amawonedwa ngati hypoallergenic popeza ulusi waukulu ndi zamkati zamatabwa kapena thonje.Carboxymethylcellulose imagwiritsidwa ntchito kwambiri muzakudya zopanda gluteni komanso zochepetsera mafuta.M'zotsukira zovala, zimagwiritsidwa ntchito ngati dothi loyimitsa polima lopangidwa kuti liyike pa thonje ndi nsalu zina za cellulosic, kupanga chotchinga chotchinga dothi chachakumwa chochapira.Carboxymethylcellulose amagwiritsidwa ntchito ngati mafuta opangira misozi.Carboxymethylcellulose imagwiritsidwanso ntchito ngati thickening agent, mwachitsanzo, m'makampani obowola mafuta, komwe ndi gawo la matope obowola, pomwe amagwiritsidwa ntchito ngati viscosity modifier ndi kusungira madzi.Mwachitsanzo, sodium CMC (Na CMC) idagwiritsidwa ntchito ngati njira yoletsa kutayika tsitsi kwa akalulu.Nsalu zolukidwa kuchokera ku cellulose, monga thonje kapena viscose rayon, zimatha kusinthidwa kukhala CMCs ndikugwiritsidwa ntchito pazachipatala zosiyanasiyana.
