Carboxymethylcellulose (CMC) ndi wowuma onse ndi ma polysaccharides, koma ali ndi mawonekedwe, katundu ndi ntchito zosiyanasiyana.
Mapangidwe a mamolekyu:
1. Carboxymethylcellulose (CMC):
Carboxymethylcellulose ndi chochokera ku cellulose, polima linear yopangidwa ndi mayunitsi a shuga olumikizidwa ndi β-1,4-glycosidic bond.Kusintha kwa cellulose kumaphatikizapo kuyambitsa magulu a carboxymethyl kudzera mu etherification, kupanga carboxymethylcellulose.Gulu la carboxymethyl limapangitsa CMC kusungunuka m'madzi ndikupatsanso ma polima apadera.
2. Wowuma:
Wowuma ndi kagayidwe kachakudya kopangidwa ndi mayunitsi a glucose olumikizidwa ndi α-1,4-glycosidic bond.Ndi polima yachilengedwe yomwe imapezeka muzomera zomwe zimagwiritsidwa ntchito ngati chosungira mphamvu.Mamolekyu owuma nthawi zambiri amapangidwa ndi mitundu iwiri ya ma polima a shuga: amylose (unyolo wowongoka) ndi amylopectin (magawo anthambi).
Zakuthupi:
1. Carboxymethylcellulose (CMC):
Kusungunuka: CMC imasungunuka m'madzi chifukwa cha kukhalapo kwa magulu a carboxymethyl.
Viscosity: Imawonetsa kukhuthala kwakukulu mu yankho, ndikupangitsa kuti ikhale yofunikira pazinthu zosiyanasiyana monga kukonza chakudya ndi mankhwala.
Kuwonekera: Mayankho a CMC nthawi zambiri amakhala owonekera.
2. Wowuma:
Kusungunuka: Wowuma wamba sasungunuka m'madzi.Imafunika gelatinization (kutentha m'madzi) kuti isungunuke.
Viscosity: Phala la wowuma lili ndi kukhuthala, koma nthawi zambiri limakhala lotsika kuposa CMC.
Kuwonekera: Miyala yowuma imakhala yosawoneka bwino, ndipo kuchuluka kwa kuwala kumatha kusiyanasiyana malinga ndi mtundu wa wowuma.
gwero:
1. Carboxymethylcellulose (CMC):
CMC imapangidwa kuchokera ku cellulose kuchokera ku zomera monga zamkati kapena thonje.
2. Wowuma:
Zomera monga chimanga, tirigu, mbatata ndi mpunga zili ndi wowuma wambiri.Ndilo gawo lalikulu muzakudya zambiri zokhazikika.
Ndondomeko Yopanga:
1. Carboxymethylcellulose (CMC):
Kupanga kwa CMC kumakhudzanso etherification ya cellulose ndi chloroacetic acid mu sing'anga yamchere.Izi zimapangitsa kuti magulu a hydroxyl alowe m'malo mwa cellulose ndi magulu a carboxymethyl.
2. Wowuma:
Kuchotsa wowuma kumaphatikizapo kuphwanya maselo a zomera ndikupatula ma granules owuma.Wowuma wochotsedwa amatha kutsata njira zosiyanasiyana, kuphatikiza kusinthidwa ndi gelatinization, kuti mupeze zomwe mukufuna.
Cholinga ndi kugwiritsa ntchito:
1. Carboxymethylcellulose (CMC):
Makampani azakudya: CMC imagwiritsidwa ntchito ngati thickener, stabilizer ndi emulsifier muzakudya zosiyanasiyana.
Mankhwala: Chifukwa cha kumangiriza kwake ndi kusweka, amagwiritsidwa ntchito m'mapangidwe amankhwala.
Kubowola Mafuta: CMC imagwiritsidwa ntchito pobowola mafuta kuwongolera rheology.
2. Wowuma:
Makampani azakudya: Wowuma ndiye gawo lalikulu lazakudya zambiri ndipo amagwiritsidwa ntchito ngati thickening, gelling agent ndi stabilizer.
Makampani opanga nsalu: Wowuma amagwiritsidwa ntchito popanga nsalu kuti apange kuuma kwa nsalu.
Makampani opanga mapepala: Wowuma amagwiritsidwa ntchito popanga mapepala kuti awonjezere mphamvu zamapepala komanso kukonza zinthu zapamtunda.
Ngakhale CMC ndi wowuma onse ndi ma polysaccharides, ali ndi kusiyana kwa mamolekyulu, katundu wakuthupi, magwero, njira zopangira ndi kugwiritsa ntchito.CMC ndiyosungunuka m'madzi komanso yowoneka bwino kwambiri ndipo nthawi zambiri imakonda kugwiritsa ntchito zinthu zomwe zimafunikira izi, pomwe wowuma ndi polysaccharide yosunthika yomwe imagwiritsidwa ntchito kwambiri m'makampani azakudya, nsalu ndi mapepala.Kumvetsetsa kusiyana kumeneku ndikofunikira pakusankha polima yoyenera pazinthu zina zamakampani ndi zamalonda.
