Mwepụta cellulose dị ka ihe mgbakwunye nri

Ruo ogologo oge, a na-eji ihe ndị sitere na cellulose eme ihe na ụlọ ọrụ nri. Mgbanwe nke anụ ahụ nke cellulose nwere ike ịhazigharị akụrụngwa rheological, hydration na anụ ahụ nke sistem. Ọrụ ise dị mkpa nke cellulose emezigharịrị kemịkalụ na nri bụ: rheology, emulsification, nkwụsi ike ụfụfụ, ịchịkwa nhazi kristal ice na uto, na ike ijikọta mmiri.

Microcrystalline cellulose dị ka ihe mgbakwunye nri ekwenyela na Kọmitii Na-ahụ Maka Nri nri nke International Health Organisation na 1971. N'ụlọ ọrụ nri, a na-ejikarị microcrystalline cellulose eme ihe dị ka emulsifier, foam stabilizer, nnukwu okpomọkụ stabilizer, onye na-adịghị edozi nri, thickener. , onye nkwusioru, onye na-ejigide ọdịdị na onye na-emepụta ice crystal. Na mba ụwa, enweela ngwa nke microcrystalline cellulose iji rụpụta nri kpọnwụrụ akpọnwụ, desserts ihe ọṅụṅụ oyi, na nri nri; iji microcrystalline cellulose na ngwaahịa carboxylated ya dị ka ihe mgbakwunye maka imepụta mmanụ salad, abụba mmiri ara ehi, na dextrin sizinin; Ngwa emetụtara nke nutraceuticals na ọgwụ maka ndị ọrịa mamịrị.

Microcrystalline cellulose nwere urughuru kristal nke 0.1-2 μm bụ ọkwa colloidal. Colloidal microcrystalline cellulose bụ stabilizer nke si mba ofesi ebubata maka mmepụta mmiri ara ehi. N'ihi nkwụsi ike ya dị mma na uto ya, ọ na-aghọwanye ewu ewu. A na-ejikarị ya eme ihe na-emepụta ihe ọṅụṅụ dị elu, karịsịa na mmepụta nke mmiri ara ehi calcium dị elu, mmiri ara ehi koko, mmiri ara ehi ukpa, mmiri ara ehi ahụekere, wdg Mgbe a na-eji colloidal microcrystalline cellulose na-ejikọta ya na carrageenan, ọ nwere ike dozie nkwụsi ike. nsogbu nke ọtụtụ ihe ọṅụṅụ mmiri ara ehi na-anọpụ iche.

Methyl cellulose (MC) ma ọ bụ gbanwetụrụ akwukwo nri chịngọm na hydroxyprolyl methyl cellulose (HPMC) na-ma gbaara dị ka nri mgbakwunye, ma nwere elu ọrụ, nwere ike hydrolyzed na mmiri na mfe Film-akpụ, thermally decomposed n'ime hydroxyprolyl methylcellulose methoxyl na hydroxyprolyl components. Methylcellulose na hydroxyprolylmethylcellulose nwere uto mmanụ, nwere ike kechie ọtụtụ afụ ikuku, ma nwee ọrụ nke idebe mmiri. A na-eji ya na ngwaahịa bred, nri kpọnwụrụ akpọnwụ, ofe (dị ka ngwugwu noodle ozugbo), sauces na nri ụlọ. Hydroxypropyl methylcellulose nwere ezigbo solubility mmiri na ahụ mmadụ anaghị agbaze ya ma ọ bụ fermented site na microorganisms na eriri afọ. Ọ nwere ike ibelata ọkwa cholesterol ma nwee mmetụta nke igbochi ọbara mgbali elu mgbe ejiri ya ogologo oge.

CMC bụ carboxymethyl cellulose, na United States etinyela CMC na United States Code of Federal Regulations, nke a ghọtara dị ka ihe dị mma. Òtù Na-ahụ Maka Nri na Ọrụ Ugbo nke United Nations na Òtù Ahụ Ike Ụwa ghọtara na CMC adịghị mma, na ihe oriri a na-enye kwa ụbọchị maka ụmụ mmadụ bụ 30 mg / kg. CMC nwere ọrụ pụrụ iche nke ịdị n'otu, ịdị arọ, nkwusioru, nkwụsi ike, mgbasa, njigide mmiri na gelling. Ya mere, CMC nwere ike iji dị ka thickener, stabilizer, suspending, dispersant, emulsifier, wetting agent, gelling agent na ihe oriri ndị ọzọ na ụlọ ọrụ nri, ma jiri ya mee ihe na mba dị iche iche.
