Cellulose:
Cellulose ke macromolecular polysaccharide e entsoeng ka tsoekere 'me ke karolo ea mantlha ea sebopeho sa marako a lisele tsa semela. Mochesong oa kamore, selulose ha e qhibilihe ka metsing kapa ka har'a lihlapolli tse tloaelehileng. Likahare tsa cellulose tsa k'hothone li haufi le 100%, e leng se etsang hore e be mohloli o hloekileng oa tlhaho oa cellulose. Ka kakaretso lehong, selulose e etsa 40-50%, 'me ho na le 10-30% ea hemicellulose le 20-30% lignin.
Phapang pakeng tsa cellulose (ka ho le letona) le starch (ka ho le letšehali):
Ka kakaretso, starch le cellulose ke macromolecular polysaccharides, 'me mokhoa oa molek'hule o ka hlalosoa e le (C6H10O5) n. Boima ba limolek'hule ba selulose bo boholo ho feta ba starch, 'me cellulose e ka bola ho hlahisa starch. Cellulose ke D-glucose le β-1,4 glycoside Macromolecular polysaccharides e entsoeng ka litlamo, ha starch e thehoa ke α-1,4 glycosidic bonds. Cellulose ka kakaretso ha e na makala, empa starch e na le makala a 1,6 a glycosidic. Cellulose ha e qhibilihe hantle ka metsing, athe starch eona e qhibiliha metsing a chesang. Cellulose ha e utloe ho amylase 'me ha e fetohe putsoa ha e pepesehetse iodine.
Cellulose Ether:
Lebitso la Senyesemane lacellulose etherke cellulose ether, e leng motsoako oa polymer o nang le sebopeho sa ether se entsoeng ka selulose. Ke sehlahisoa sa karabelo ea lik'hemik'hale ea cellulose (semela) e nang le etherification agent. Ho ea ka sebopeho sa lik'hemik'hale tsa motsoako ka mor'a etherification, e ka aroloa ka anionic, cationic le nonionic ethers. Ho itšetlehile ka etherification agent e sebelisitsoeng, ho na le methyl cellulose, hydroxyethyl methyl cellulose, carboxymethyl cellulose, ethyl cellulose, benzyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, cyanoethyl cellulose, benzyl cyanoethyl cellulose, carboxymethyl cellulose, carboxymethyl cellulose, carboxymethyl cellulose joalo-joalo. Indastering ea kaho, cellulose ether e boetse e bitsoa cellulose, e leng lebitso le sa tloaelehang, 'me e bitsoa cellulose (kapa ether) ka nepo.
Mokhoa o tiileng oa Cellulose Ether Thickener:
Li-cellulose ether thickeners ke li-non-ionic thickeners tse teteaneng haholo-holo ka ho kenngoa ha metsi le ho kena lipakeng tsa limolek'hule.
