01. Katundu wa cellulose ya microcrystalline
Microcrystalline mapadi ndi odorless, zabwino kwambiri woyera yochepa ndodo porous tinthu, tinthu kukula zambiri 20-80 μm (microcrystalline mapadi ndi galasi tinthu kukula 0.2-2 μm ndi colloidal kalasi), ndi malire digiri polymerization (LODP). ) pakati pa 15-375;zopanda fibrous koma zamadzimadzi kwambiri;zosasungunuka m'madzi, zidulo zosungunuka, zosungunulira organic ndi mafuta, zimasungunuka pang'ono ndikufufutira munjira za alkali.Ili ndi reactivity yayikulu mumayendedwe a carboxymethylation, acetylation ndi esterification.Ndizopindulitsa kwambiri pakusintha kwamankhwala ndikugwiritsa ntchito.
Ma cellulose a Microcrystalline ali ndi zinthu zitatu zofunika:
1) Digiri yapakati ya polymerization imafika pamlingo wa digiri ya polymerization
2) Mlingo wa crystallinity ndi wapamwamba kuposa wa cellulose yaiwisi
3 imakhala ndi mayamwidwe amphamvu amadzi, ndipo imatha kupanga guluu pambuyo pometa mwamphamvu m'madzi
02. Kugwiritsa ntchito cellulose ya microcrystalline muzakudya
2.1 Pitirizani kukhazikika kwa emulsification ndi thovu
Kukhazikika kwa emulsion ndi ntchito yofunika kwambiri ya cellcrystalline cellulose.Microcrystalline mapadi particles omwazika mu emulsion kuti thicken ndi gel osakaniza madzi gawo mu mafuta-madzi emulsion, potero kuteteza mafuta m'malovu kuyandikira wina ndi mzake ndipo ngakhale aggregating.
Mwachitsanzo, kutsika kwa pH ya yoghurt kungapangitse kuti zinthu zolimba za mkaka zigwirizane, zomwe zimapangitsa kuti whey asiyane ndi kusakaniza.Kuonjezera cellulose ya microcrystalline ku yogurt kungathe kutsimikizira kukhazikika kwa mkaka.Pambuyo powonjezera microcrystalline cellulose stabilizer ku ayisikilimu, kukhazikika kwake kwa emulsification, kukhazikika kwa thovu ndi luso lopewera kristalo kumakhala bwino kwambiri, ndipo poyerekeza ndi ma stabilizer osungunuka a polima pawiri, ayisikilimu ndi osalala komanso otsitsimula.
2.2 Sungani kutentha kwakukulu
Pa processing wa chakudya aseptic, pali onse kutentha ndi mkulu mamasukidwe akayendedwe.Wowuma amawola mumikhalidwe yotere, ndipo kuwonjezera cellulose ya microcrystalline ku chakudya cha aseptic kumatha kukhalabe ndi mawonekedwe ake abwino.Mwachitsanzo, emulsion mu nyama zamzitini amatha kukhalabe chimodzimodzi akatenthedwa pa 116 ° C kwa maola atatu.
2.3 Konzani kukhazikika kwamadzimadzi, ndikuchita ngati gwero komanso kuyimitsa
Pamene zakumwa zapompopompo zimabalalitsidwanso m'madzi, kubalalikana kosafanana kapena kusakhazikika pang'ono kumachitika nthawi zambiri.Kuonjezera kuchuluka kwa colloidal cellulose kumatha kupanga njira yokhazikika ya colloidal, ndipo dispersibility ndi bata zimakula bwino.Kuonjezera stabilizer yopangidwa ndi colloidal microcrystalline cellulose, wowuma ndi maltodextrin ku chokoleti pompopompo kapena zakumwa za cocoa sizingalepheretse ufa wa zakumwa zapompopompo kukhala zonyowa komanso zosakanikirana, komanso zimapangitsa kuti zakumwa zokonzedwa ndi madzi zikhale zokhazikika komanso zobalalika zogonana.
2.4 Monga chowonjezera chosapatsa thanzi komanso chokhuthala, konzani kapangidwe ka chakudya
Cholowa m'malo mwa ufa chomwe chimapezedwa posakaniza cellulose ya microcrystalline, xanthan chingamu, ndi lecithin amagwiritsidwa ntchito pophika.Pamene kuchuluka kwa m'malo sikudutsa 50% ya ufa woyambirira womwe umagwiritsidwa ntchito, ukhoza kusunga kukoma koyambirira ndipo nthawi zambiri sikukhudzidwa ndi lilime.Kukula kwakukulu kwa particles zoimbidwa ndi 40 μm, choncho, 80% ya microcrystalline cellulose particle size imayenera kukhala <20 μm.
2.5 Kuwonjezera pa zokometsera zoziziritsa kukhosi kuwongolera mapangidwe a ice crystal
Chifukwa cha kukhalapo kwa cellulose ya microcrystalline mumayendedwe oundana pafupipafupi, imakhala ngati chotchinga chakuthupi, chomwe chingalepheretse njere za kristalo kuti zisagwirizane kukhala makhiristo akulu.Mwachitsanzo, bola ngati 0.4-0.6% microcrystalline mapadi akuwonjezeredwa ayisikilimu, ndi zokwanira kuteteza ayezi galasi njere kuchulukira pa kuzizira pafupipafupi ndi thawing, ndi kuonetsetsa kuti kapangidwe ndi kapangidwe ake sizisintha, ndi microcrystalline. cellulose particles ndi zabwino kwambiri, Ikhoza kuonjezera kukoma.Powonjezera 0,3%, 0.55%, ndi 0,80% microcrystalline mapadi ku ayisikilimu okonzedwa ndi mmene British chilinganizo, kukhuthala kwa ayisikilimu ndi apamwamba pang'ono kuposa popanda kuwonjezera microcrystalline mapadi, ndipo alibe mphamvu pa kuchuluka kwa kutayikira, ndi akhoza Kupititsa patsogolo kapangidwe kake.
2.6 Microcrystalline cellulose imagwiritsidwanso ntchito kuchepetsa zopatsa mphamvu
Ngati mugwiritsa ntchito kuvala saladi, chepetsani zopatsa mphamvu ndikuwonjezera ma cellulose kuti muwonjezere zodyedwa.Popanga zokometsera zosiyanasiyana zamafuta ophikira, kuwonjezera pa cellulose ya microcrystalline kumatha kulepheretsa mafuta kulekana ndi msuzi akatenthedwa kapena kuwiritsa.
2.7 Ena
Chifukwa cha ma adsorption a cellulose ya microcrystalline, zakudya zomwe zimakhala ndi mchere wambiri zimatha kupezeka kudzera mu ma adsorption a ayoni achitsulo.
