ʻO ka microcrystalline cellulose he hua'ōlelo no ka pulp lāʻau i hoʻomaʻemaʻeʻia a hoʻohanaʻia ma keʻano he texturizer, he anti-caking agent, he momona momona, he emulsifier, he extender, a he bulking agent i ka hana meaʻai. nā papa. Hoʻohana ʻia ia i nā hoʻokolohua plaque no ka helu ʻana i nā maʻi maʻi, ma ke ʻano he mea ʻokoʻa i ka carboxymethylcellulose. He polymer maoli, ua haku ʻia me nā ʻāpana glucose i hoʻopili ʻia e kahi paʻa 1-4 beta glycosidic. Hoʻopili pū ʻia kēia mau kaulahao cellulose linear e like me ka microfibril i hoʻopili pū ʻia i loko o nā paia o nā mea kanu. Hōʻike kēlā me kēia microfibril i kahi kiʻekiʻe kiʻekiʻe o ka hoʻopaʻa ʻana i loko ʻekolu-dimensional i loaʻa i kahi ʻano crystalline i hiki ʻole ke hoʻoheheʻe ʻia i ka wai a kū i nā reagents. Aia nō naʻe nā ʻāpana nāwaliwali o ka microfibril me ka nawaliwali o ka paʻa kūloko. Ua kapa ʻia kēia mau ʻāina amorphous akā ua kapa ʻia ʻo ia he dislocations mai ka microfibril i loaʻa i ka hoʻolālā hoʻokahi. Hoʻokaʻawale ʻia ka ʻāina crystalline e hana i ka microcrystalline cellulose.
