Kugadzirwa kwemaindasitiri erythritol kunonyanya kutora microbial fermentation nzira, pane kutora zvakananga kubva kumiti yechisikigo. Izvi zvinodaro nekuti erythritol ine yakaderera yemukati muzvarirwo, uye kudhirowa kwakananga kunodhura uye kusashanda. Aya anotevera maitiro epakati uye tekinoroji mapoinzi ekugadzirwa kwemaindasitiri erythritol:

Mainstream kugadzira nzira: Microbial fermentation nzira
Kusarudzwa kwehutachiwana hwebhakitiriya

Core strains: Yeast inoburitsa erythritol yakawanda (yakadai seMoniliella pollinis, Yarrowia lipolytica) kana mold (yakadai seTrichosporonoides megachiliensis).
Genetic engineering optimization: Tekinoroji yemazuva ano inosimudzira chiyero chekushandurwa kweshuga uye yakakwira osmotic kudzvinyirirwa kwehutachiona hwehutachiona kuburikidza nekuchinja kwemajini.
Raw material processing

Carbon source: Shandisa glucose kana sucrose solution (ine kuungana kunosvika 30-35%, kugadzira nzvimbo yakakwirira yeosmotic kukurudzira erythritol synthesis).
Pre treatment: Zvigadzirwa zvakachipa zvakaita sechibage starch zvinoda kushandurwa kuita glucose kuburikidza ne enzymatic hydrolysis (α - amylase + amylase).
Fermentation process

Kuvirisa kunodzorwa neokisijeni: Ita kuvirisa kwakadzika mumatangi makuru ekuvirisa, nyatso kudzora pH (5.0-6.0), tembiricha (28-34 ℃), uye mwero weokisijeni wakanyungudika.
High osmotic pressure induction: Pasi pehuwandu hweglucose, ma microorganisms anoshandura imwe glucose kuita erythritol kuenzanisa cell osmotic pressure.
Matanho akakosha ekuparadzana nekucheneswa

Unyanzvi hwematanho
Sterilization filtration, microfiltration kana centrifugation kubvisa mabhakitiriya maseru uye kusvibiswa kwakakura kwema molecular.
Decolorization desalination activated carbon adsorbs pigments, ion exchange resin inobvisa inorganic salt.
Concentrated crystallization vacuum evaporation concentration kune supersaturation → kutonhora crystallization (kutonga kuwedzera kwembeu uye kutonhora kwemazinga)
Centrifugal drying, centrifugal kupatsanurwa kwemakristasi → fluidized bed drying kuwana makristasi machena nekuchena kukuru kupfuura 99.5%
Kuvapo kwechisikigo uye kudhirowa chiyero (kwete maindasitiri)
Kunyangwe kugadzirwa kwemaindasitiri kuchitsamira pakuvirisa, erythritol inongowanikwa mu:

Zvibereko: mazambiringa, mapeya, watermelon (zviri mukati 0.005-0.1%)
Zvokudya zvakaviriswa: soy muto, sake
Kutora nzira yekuyedza (yezvinangwa zvesainzi chete):

Zvakaipa: Goho rakaderera zvakanyanya (Kuenzanisa zvakanakira nemamwe shuga doro kugadzirwa
Hunhu erythritol xylitol/sorbitol
Fermentation substrate glucose/sucrose hemicellulose hydrolyzate (xylose)
Kuomerwa kweCrystallization: Nyore kupenya (solubility ye37g/100g pa25 ℃). Sorbitol inoda kupenya zvishoma nezvishoma kudzivirira kugwamba
Metabolic nzira: Muviri wemunhu haugadzike (Kufambira mberi kwehunyanzvi
Kushandiswa kwemarara: Kuedza kutsiva glucose yakanatswa ne lignocellulose hydrolyzate kuderedza mari yemidziyo neinodarika 30%.
Kuenderera mberi kuvirisa: Iyo itsva membrane bioreactor inowana inoenderera kugadzirwa, ichipfupisa kuvirisa kutenderera kusvika kumaawa makumi mana nemasere.
Green crystallization: Ultrasonic inobatsira crystallization teknolojia inovandudza crystal kuchena (> 99.9%) uye inoderedza kushandiswa kwesimba.
Mhedziso
"Kutorwa" kwe erythritol kunoreva chaizvo maindasitiri ekuvirisa kupatsanurwa maitiro, uye kubviswa kwechisikigo kunongoreva kukosha kwedzidziso. Tekinoroji yemazuva ano inoshandisa marara akagadzirwa nemajini, kuvirisa kwakanyanya, uye nzira dzakawanda dzekunatsa kuti uwane kugadzirwa kwakachipa kwemamiriyoni ematani pagore, zvichizadzisa kudiwa kwezero yehuga chikafu. Kana maparamendi chaiwo emaitiro kana ruzivo rwepatent ruchidikanwa, rumwe rubatsiro rwemabhuku runogona kupihwa.
