ʻO ka Cellulose, kahi polysaccharide i haku ʻia me nā monomers glucose i hoʻopili ʻia e nā pilina β-1,4-glycosidic, ʻo ia ka polymer organik nui loa ma ka Honua. Loaʻa nui ʻia i loko o nā paia cell o nā mea kanu, hāʻawi ia i ka paʻa o ke ʻano, e hiki ai i nā lāʻau ke piʻi i nā kiʻekiʻe nui a me nā lau e mālama i ko lākou ʻano. ʻO ka pulupulu, ke kumu kūlohelohe maʻemaʻe loa o ka cellulose, aia a hiki i ka 90% o kēia polymer, ʻoiai ʻo ka lāʻau maʻamau he 40-50% cellulose, me ka lignin a me ka hemicellulose. Hoʻopuka pū ka algae a me kekahi mau bacteria i ka cellulose, e hoʻonui ana i kona hoʻolaha kūlohelohe.

ʻO ka unuhi ʻana o ka cellulose e pili ana i ka hoʻokaʻawale ʻana iā ia mai nā ʻāpana mea kanu ʻē aʻe. I loko o ka ʻoihana pulp a me ka pepa, hana ʻia nā ʻāpana lāʻau i ka pulping kemika (me ka hoʻohana ʻana i nā sulfates a i ʻole sulfites) a i ʻole ka wili mechanical e wehe i ka lignin a hoʻokaʻawale i nā olonā cellulose. No nā noi maʻemaʻe kiʻekiʻe, e like me nā huahana lāʻau lapaʻau a me nā huahana meaʻai, hoʻohana ʻia nā ʻanuʻu hoʻomaʻemaʻe hou e like me ka bleaching a me ka mālama enzymatic. ʻO Nanocellulose, i loaʻa mai ka cellulose ma o ka hydrolysis acid a i ʻole ka fibrillation mechanical, ua puka mai ma ke ʻano he mea waiwai nui ma muli o kona mau waiwai kū hoʻokahi ma ka nanoscale.

ʻO ka versatility o ka Cellulose e hoʻokele i kona hoʻohana nui ʻana ma nā ʻoihana.hana pepa, ʻo nā olonā cellulose ka mea maka mua, e hāʻawi ana i ka ikaika a me ka maʻalahi i nā huahana pepa. I loko o kaʻoihana lole, ua milo ʻia ka pulupulu cellulose i loko o nā olonā a ulana ʻia i loko o nā lole, i mahalo ʻia no ko lākou hanu ʻana a me ka ʻoluʻolu.nā noi meaʻai, lawelawe ka cellulose ma ke ʻano he fiber dietary, e paipai ana i ke olakino ʻōpū, a hana ma ke ʻano he mea hoʻomānoanoa, mea hoʻopaʻa, a i ʻole emulsifier i nā huahana e like me ka ice cream a me nā ʻaʻahu salakeke.
