Kupanga kwa erythritol m'mafakitale kumagwiritsa ntchito njira yowotchera ma tizilombo tating'onoting'ono, m'malo mochotsa mwachindunji ku zomera zachilengedwe. Izi ndichifukwa choti erythritol imakhala ndi zinthu zochepa m'chilengedwe, ndipo kuchotsa mwachindunji kumakhala kokwera mtengo komanso kosathandiza. Zotsatirazi ndizomwe zimayambira komanso mfundo zaukadaulo pakupangira mafakitale a erythritol:

Njira yayikulu yopangira: Njira yowotchera ma Microbial
Kusankha mitundu ya bakiteriya

Mitundu yapakati: Yisiti yotulutsa erythritol (monga Moniliella pollinis, Yarrowia lipolytica) kapena nkhungu (monga Trichosporonoides megachiliensis).
Kukhathamiritsa kwa uinjiniya wa ma genetic: Ukadaulo wamakono umakulitsa kuchuluka kwa kutembenuka kwa mowa wa shuga komanso kuthamanga kwamphamvu kwa osmotic kwa mitundu ya bakiteriya kudzera mukusintha kwa majini.
Yaiwisi processing

Gwero la mpweya: Gwiritsani ntchito shuga kapena sucrose solution (yokhala ndi ndende yofikira 30-35%, kupanga malo okhala ndi osmotic apamwamba kuti alimbikitse kaphatikizidwe ka erythritol).
Chithandizo chisanachitike: Zida zotsika mtengo monga wowuma wa chimanga ziyenera kusinthidwa kukhala shuga kudzera mu enzymatic hydrolysis (α - amylase+amylase).
Njira yowotchera

Kuwotchera koyendetsedwa ndi okosijeni: Yesetsani kuyatsa kwakuya kwa mpweya m'matangi akuluakulu, kuwongolera mosamalitsa pH (5.0-6.0), kutentha (28-34 ℃), ndi mulingo wa okosijeni wosungunuka.
High osmotic pressure induction: Pansi pa kuchuluka kwa glucose, tinthu tating'onoting'ono timasintha shuga kukhala erythritol kuti muchepetse kuthamanga kwa cell osmotic.
Njira zazikulu zopatukana ndi kuyeretsedwa

Tsatanetsatane waukadaulo wamasitepe
Sterilization kusefera, microfiltration kapena centrifugation kuchotsa ma cell a bakiteriya ndi zonyansa zazikulu zama cell
Decolorization desalination adamulowetsa mpweya adsorbs inki, ion kuwombola utomoni amachotsa mchere mchere
Kukhazikika kwa crystallization vacuum evaporation concentration to supersaturation → kuzirala crystallization (kulamulira kuonjezera kwa mbeu ndi kuzirala)
Kuyanika kwa centrifugal, kulekanitsa makhiristo pakatikati → kuyanika bedi kwamadzimadzi kuti mupeze makhiristo oyera ndi oyera kuposa 99.5%
Kukhalapo kwachilengedwe komanso kuchotsera pang'ono (osati mafakitale)
Ngakhale kupanga mafakitale kumadalira nayonso mphamvu, erythritol mwachilengedwe imapezeka mu:

Zipatso: mphesa, mapeyala, mavwende (zomwe zili pafupifupi 0.005-0.1%)
Zakudya zokazinga: msuzi wa soya, sake
Njira yoyesera m'zigawo (zolinga zofufuza zasayansi zokha):

A [Kugaya Zitsanzo] -->B [Kuthira Madzi Otentha]
B -> C [Ethanol precipitation polysaccharides]
C --> D [kuyeretsa chromatography ion kusinthana]
D -> E [HPLC kupatukana kwa erythritol]
Zoipa: Zokolola zotsika kwambiri (Kuyerekeza ubwino ndi zina shuga mowa mowa
Makhalidwe a erythritol xylitol/sorbitol
Kuwiritsa gawo lapansi shuga/sucrose hemicellulose hydrolyzate (xylose)
Crystallization zovuta: Easy crystallize (kusungunuka kwa 37g/100g pa 25 ℃). Sorbitol iyenera kuwunikira pang'onopang'ono kuti ipewe kugwa
Njira ya kagayidwe: Thupi la munthu silimasungunuka (Kupita patsogolo kwaukadaulo
Kugwiritsa ntchito zinyalala: Yesani kusintha shuga woyengedwa ndi lignocellulose hydrolyzate kuti muchepetse mtengo wazinthu zopangira ndi 30%.
Kuwotchera kosalekeza: The new membrane bioreactor imakwaniritsa kupanga mosalekeza, kufupikitsa nthawi ya nayonso mphamvu mpaka maola 48.
Green crystallization: Akupanga anathandiza crystallization luso bwino galasi chiyero (> 99.9%) ndi kuchepetsa mowa mphamvu.
Mapeto
"Kutulutsa" kwa erythritol kwenikweni kumatanthawuza njira yolekanitsa ya mafakitale, ndipo kutulutsa kwachilengedwe kumangokhala ndi tanthauzo longoyerekeza. Ukadaulo wamakono umagwiritsa ntchito mitundu yopangidwa ndi majini, kuthirira kwambiri, ndi njira zingapo zoyenga kuti akwaniritse kupanga zotsika mtengo zamatani mamiliyoni pachaka, kukwaniritsa kufunikira kwa chakudya cha shuga. Ngati zidziwitso zenizeni za ndondomeko kapena zovuta za patent zikufunika, thandizo lina la mabuku lingaperekedwe.
