Carboxymethylcellulose (CMC) ndi starch zonse ndi ma polysaccharide, koma ali ndi kapangidwe, makhalidwe ndi ntchito zosiyana.
Kapangidwe ka maselo:
1. Carboxymethylcellulose (CMC):
Carboxymethylcellulose ndi chinthu chochokera ku cellulose, polima yolunjika yopangidwa ndi mayunitsi a shuga olumikizidwa ndi ma bond a β-1,4-glycosidic. Kusintha kwa cellulose kumaphatikizapo kuyambitsa magulu a carboxymethyl kudzera mu etherification, ndikupanga carboxymethylcellulose. Gulu la carboxymethyl limapangitsa CMC kusungunuka m'madzi ndipo limapereka mphamvu zapadera kwa polima.
2. Wowuma:
Wowuma ndi chakudya chopangidwa ndi mayunitsi a shuga olumikizidwa ndi ma bond a α-1,4-glycosidic. Ndi polima wachilengedwe womwe umapezeka m'zomera zomwe zimagwiritsidwa ntchito ngati chosungira mphamvu. Mamolekyu a wowuma nthawi zambiri amakhala ndi mitundu iwiri ya ma polima a shuga: amylose (maunyolo owongoka) ndi amylopectin (maumbidwe a unyolo wolumikizidwa).
Kapangidwe ka thupi:
1. Carboxymethylcellulose (CMC):
Kusungunuka: CMC imasungunuka m'madzi chifukwa cha kukhalapo kwa magulu a carboxymethyl.
Kukhuthala: Imakhala ndi kukhuthala kwakukulu mu yankho, zomwe zimapangitsa kuti ikhale yothandiza pa ntchito zosiyanasiyana monga kukonza chakudya ndi mankhwala.
Kuwonekera: Mayankho a CMC nthawi zambiri amakhala owonekera.
2. Wowuma:
Kusungunuka: Wowuma wachilengedwe susungunuka m'madzi. Umafunika kutenthedwa m'madzi kuti usungunuke.
Kukhuthala: Ufa wa starch uli ndi kukhuthala, koma nthawi zambiri umakhala wochepa kuposa CMC.
Kuwonekera: Ma phala a sitachi nthawi zambiri sawonekera bwino, ndipo kuchuluka kwa kuonekera bwino kumatha kusiyana kutengera mtundu wa sitachi.
gwero:
1. Carboxymethylcellulose (CMC):
CMC nthawi zambiri imapangidwa kuchokera ku cellulose kuchokera ku zomera monga matabwa kapena thonje.
2. Wowuma:
Zomera monga chimanga, tirigu, mbatata ndi mpunga zili ndi starch yambiri. Ndi chinthu chachikulu chomwe chimapezeka muzakudya zambiri zofunika.
Njira Yopangira:
1. Carboxymethylcellulose (CMC):
Kupanga kwa CMC kumaphatikizapo etherification reaction ya cellulose ndi chloroacetic acid mu alkaline medium. Izi zimapangitsa kuti magulu a hydroxyl alowe m'malo mwa magulu a cellulose ndi magulu a carboxymethyl.
2. Wowuma:
Kuchotsa sitachi kumaphatikizapo kuswa maselo a zomera ndi kupatula timadontho ta sitachi. Sitachi wochotsedwayo amatha kuchitidwa zinthu zosiyanasiyana, kuphatikizapo kusintha ndi kuyika gelatin, kuti apeze zinthu zomwe akufuna.
Cholinga ndi kagwiritsidwe ntchito:
1. Carboxymethylcellulose (CMC):
Makampani Ogulitsa Chakudya: CMC imagwiritsidwa ntchito ngati chokhuthala, chokhazikika komanso chosakaniza mu zakudya zosiyanasiyana.
Mankhwala: Chifukwa cha mphamvu zake zomangirira ndi kusweka, amagwiritsidwa ntchito popanga mankhwala.
Kuboola Mafuta: CMC imagwiritsidwa ntchito mumadzi oboola mafuta kuti ilamulire rheology.
2. Wowuma:
Makampani Ogulitsa Chakudya: Wowuma ndiye gawo lalikulu la zakudya zambiri ndipo amagwiritsidwa ntchito ngati chowonjezera kukhuthala, chowonjezera kukhuthala komanso chokhazikika.
Makampani opanga nsalu: Wowuma amagwiritsidwa ntchito popanga kukula kwa nsalu kuti nsalu zikhale zolimba.
Makampani opanga mapepala: Wowuma amagwiritsidwa ntchito popanga mapepala kuti awonjezere mphamvu ya mapepala ndikuwonjezera mawonekedwe a pamwamba.
Ngakhale kuti CMC ndi starch zonse ndi ma polysaccharide, zimasiyana mu kapangidwe ka mamolekyulu, mawonekedwe a thupi, magwero, njira zopangira ndi kugwiritsa ntchito. CMC imasungunuka m'madzi ndipo ndi yokhuthala kwambiri ndipo nthawi zambiri imakondedwa mu ntchito zomwe zimafuna makhalidwe amenewa, pomwe starch ndi polysaccharide yogwiritsidwa ntchito kwambiri m'mafakitale azakudya, nsalu ndi mapepala. Kumvetsetsa kusiyana kumeneku ndikofunikira kwambiri posankha polima yoyenera ntchito zinazake zamafakitale ndi zamalonda.
