01. Njirimara nke microcrystalline cellulose
Microcrystalline cellulose bụ ihe na-enweghị isi, ezigbo mma na-acha ọcha mkpụmkpụ mkpirisi porous urughuru, nha ya bụ n'ozuzu 20-80 μm (microcrystalline cellulose na a kristal urughuru size nke 0.2-2 μm bụ a colloidal ọkwa), na njedebe ogo nke polymerization (LODP). ) n'etiti 15-375;na-abụghị fibrous ma oke mmiri mmiri;mmiri na-adịghị ahụkebe na mmiri, itughari acids, organic solvents na mmanụ, akụkụ ụfọdụ etisasịwo na swelled na itughari alkali ngwọta.Ọ nwere nnukwu reactivity na usoro nke carboxymethylation, acetylation na esterification.Ọ bara ezigbo uru maka mgbanwe kemịkalụ na itinye n'ọrụ.
Microcrystalline cellulose nwere njirimara atọ:

02. Ngwa nke microcrystalline cellulose na nri
2.1 Debe nkwụsi ike nke emulsification na ụfụfụ
Nkwụsi ike emulsion bụ ọrụ kachasị mkpa nke microcrystalline cellulose.Microcrystalline cellulose ahụ na-agbasasị na emulsion ka thicken na jel mmiri na-adọ na mmanụ-mmiri emulsion, si otú na-egbochi mmanụ ụmụ irighiri mmiri si nso ibe ha na ọbụna aggregating.
Dịka ọmụmaatụ, obere pH nke yogọt nwere ike ime ka ihe ndị siri ike dị na mmiri ara ehi na-agbakọta ngwa ngwa, na-eme ka whey kewapụ na ngwakọta.Ịgbakwunye microcrystalline cellulose na yogọt nwere ike hụ na nkwụsi ike nke ngwaahịa mmiri ara ehi nke ọma.Mgbe agbakwunyere microcrystalline cellulose stabilizer na ice cream, nkwụsi ike emulsification ya, nkwụsi ike ụfụfụ na ikike mgbochi ice kristal na-akawanye mma, ma e jiri ya tụnyere mmiri na-eme ka polymer compound stabilizers, ice cream dị nro ma na-enye ume ọhụrụ.
2.2 Jikwaa nkwụsi ike dị elu
N'oge nhazi nri aseptic, enwere ma elu okpomọkụ na elu viscosity.Starch ga-ere ere n'okpuru ọnọdụ ndị dị otú ahụ, na ịgbakwunye microcrystalline cellulose na nri aseptic nwere ike ịnọgide na-enwe àgwà ya magburu onwe ya.Dịka ọmụmaatụ, emulsion na ngwaahịa anụ mkpọ nwere ike ịnọgide na-enwe otu àgwà ahụ mgbe ọ na-ekpo ọkụ na 116 Celsius maka awa 3.
2.3 Melite nkwụsi ike nke mmiri mmiri, ma mee ihe dị ka onye na-ahụ maka gelling na onye na-akwụsịtụ
Mgbe a na-ekesa ihe ọṅụṅụ ozugbo na mmiri, mgbasa na-enweghị isi ma ọ bụ nkwụsi ike dị ala na-emekarị.Ịgbakwunye ụfọdụ cellulose colloidal nwere ike ịmepụta ngwọta colloidal kwụsiri ike ngwa ngwa, na mgbasawanye na nkwụsi ike na-akawanye mma.Ịgbakwunye stabilizer nke mejupụtara colloidal microcrystalline cellulose, starch na maltodextrin na ngwa ngwa chocolate ma ọ bụ ihe ọṅụṅụ koko nwere ike ọ bụghị nanị igbochi ntụ ntụ nke ihe ọṅụṅụ na-egbu egbu ka ọ bụrụ mmiri na agglomerated, ma na-eme ka ihe ọṅụṅụ ndị a kwadebere na mmiri nwere nnukwu nkwụsi ike na mmekọahụ gbasaa.
2.4 Dị ka ihe na-enweghị nri na-edozi ahụ na onye na-esi nri, kwalite nhazi nri
A na-eji ihe ndochi ntụ ọka a na-enweta site na ịgwakọta microcrystalline cellulose, xanthan gum, na lecithin n'ime ngwaahịa esiri esi.Mgbe ego ngbanwe anaghị agafe 50% nke ntụ ọka mbụ ejiri mee ihe, ọ nwere ike ịnọgide na-enwe uto mbụ na ire anaghị emetụta ya.Oke kachasị nke ụmụ irighiri ihe a na-egwu bụ 40 μm, ya mere, 80% nke microcrystalline cellulose particle size ka achọrọ ka ọ bụrụ <20 μm.
2.5 mgbakwunye na desserts oyi kpọnwụrụ iji chịkwaa nhazi kristal ice
N'ihi ọnụnọ nke microcrystalline cellulose na usoro nkwụsịtụ na-emekarị, ọ na-arụ ọrụ dị ka ihe mgbochi anụ ahụ, nke nwere ike igbochi mkpụrụ kristal ka ọ ghara ịba ụba n'ime nnukwu kristal.Dịka ọmụmaatụ, ọ bụrụhaala na 0.4-0.6% microcrystalline cellulose na-agbakwunye na ice cream, ọ ga-ezuru iji gbochie mkpụrụ osisi kristal nke ice ka ọ ghara ịba ụba n'oge oyi na-agbaze ugboro ugboro, na iji hụ na ọdịdị ya na nhazi ya adịghị agbanwe, na microcrystalline. Mkpụrụ ndụ cellulose dị oke mma, nwere ike ịbawanye uto.Na-agbakwunye 0.3%, 0.55%, na 0.80% microcrystalline cellulose na ice cream nke a kwadebere site na usoro British nkịtị, viscosity nke ice cream dị ntakịrị elu karịa nke ahụ na-agbakwunyeghị microcrystalline cellulose, ọ dịghịkwa enwe mmetụta na ego nke ịwụfu, na nwere ike melite udidi.
2.6 Microcrystalline cellulose na-ejikwa belata calorie
Ọ bụrụ na ejiri ya na mgbakwasa salad, belata calorie ma mụbaa cellulose iji meziwanye ihe oriri.Mgbe ị na-eme mmanụ esi nri dị iche iche, ịgbakwunye microcrystalline cellulose nwere ike igbochi mmanụ ahụ ikewapụ na ihendori mgbe ọ dị ọkụ ma ọ bụ sie ya.
