Samar da masana'antu na erythritol galibi yana ?aukar hanyar fermentation na ?wayoyin cuta, maimakon cirewa kai tsaye daga tsire-tsire na halitta. Wannan shi ne saboda erythritol yana da ?ananan abun ciki a cikin yanayi, kuma hakar kai tsaye yana da tsada da rashin inganci. Wadannan su ne ainihin matakai da wuraren fasaha don samar da masana'antu na erythritol:

Hanyar samarwa na yau da kullun: Hanyar ha?ewar ?wayoyin cuta
Za?in nau'ikan ?wayoyin cuta

Matsakaicin mahimmanci: Yisti mai yawan samar da erythritol (kamar Moniliella pollinis, Yarrowia lipolytica) ko mold (irin su Trichosporonoides megachiliensis).
Ha?aka aikin injiniyan kwayoyin halitta: Fasahar zamani tana ha?aka ?imar canjin barasa mai sukari da babban juriya na osmotic na ?wayoyin cuta ta hanyar gyare-gyaren kwayoyin halitta.
sarrafa albarkatun kasa

Tushen Carbon: Yi amfani da glucose ko maganin sucrose (tare da maida hankali har zuwa 30-35%, ?ir?irar yanayi mai girma na osmotic don ha?aka ha?in erythritol).
Kafin magani: Kayan albarkatun mai arha kamar sitacin masara suna bu?atar canzawa zuwa glucose ta hanyar enzymatic hydrolysis (α-amylase+amylase).
Tsarin hadi

Oxygen sarrafawa fermentation: Gudanar da zurfin aeration fermentation a cikin manyan fermentation tankuna, tsananin iko pH (5.0-6.0), zazzabi (28-34 ℃), da kuma narkar da oxygen matakin.
Babban shigar da matsa lamba na osmotic: A ?ar?ashin babban taro na glucose, ?ananan ?wayoyin cuta suna canza wasu glucose zuwa erythritol don daidaita ma'aunin osmotic cell.
Mabu?in matakai don rabuwa da tsarkakewa

Bayanan fasaha na matakai
Filtration na haifuwa, microfiltration ko centrifugation don cire ?wayoyin ?wayoyin cuta da ?azantattun ?wayoyin cuta.
Decolorization desalination kunna carbon adsorbs pigments, ion musayar guduro yana cire inorganic salts
Matsakaicin ?wan?wasa injin ?an?ara mai ?yalli zuwa supersaturation → sanyaya crystallization (samar da ?ari iri da ?imar sanyaya)
Centrifugal bushewa, centrifugal rabuwa na lu'ulu'u → ruwan gado bushewa don samun farin lu'ulu'u tare da tsarki fiye da 99.5%
Kasancewar dabi'a da ?ananan sikelin hakar (ba masana'antu ba)
Kodayake samar da masana'antu ya dogara da fermentation, erythritol a dabi'a yana wanzu a:

'Ya'yan it?cen marmari: inabi, pears, kankana (abun ciki kamar 0.005-0.1%)
Abinci mai gina jiki: soya miya, sake
Hanyar gwajin hakar (don dalilai na binciken kimiyya kawai):
budurwa
Kwafi Code
Farashin LR
A [Sample Nika] --> B [Hadin Ruwa mai zafi]
B -> C [Ethanol hazo polysaccharides]
C --> D [ion musayar chromatography tsarkakewa]
D --> E [HPLC rabuwa na erythritol]
Hasara: Matsakaicin yawan amfanin ?asa (Fa'idodin kwatancen tare da sauran samar da barasa na sukari
Halayen erythritol xylitol/sorbitol
Sucrose hemicellulose hydrolyzate (xylose)
Wahalar crystallization: Sau?i don crystallize (slubility na 37g/100g a 25 ℃). Sorbitol yana bu?atar crystallize a hankali don hana kumbura
Hanyar Metabolic: Jikin ?an adam baya ha?aka (Ci gaban fasaha
Yin amfani da sharar gida: ?o?arin maye gurbin glucose mai ladabi tare da lignocellulose hydrolyzate don rage farashin albarkatun ?asa da fiye da 30%.
Ci gaba da fermentation: Sabon membrane bioreactor yana samun ci gaba da samarwa, yana rage zagayowar fermentation zuwa awanni 48.
Green crystallization: Ultrasonic taimaka crystallization fasahar inganta crystal tsarki (> 99.9%) da kuma rage makamashi amfani.
Kammalawa
"hadin" na erythritol a zahiri yana nufin tsarin rabuwar fermentation na masana'antu, kuma hakar halitta kawai yana da mahimmancin ka'ida. Fasahar zamani tana amfani da nau'ikan injina na kwayoyin halitta, ha?akar mai da hankali sosai, da dabarun tacewa da yawa don cimma samar da ?arancin farashi na miliyoyin ton a kowace shekara, tare da biyan bu?atun abinci na sifiri. Idan ana bu?atar takamaiman sigogi na tsari ko kuma bayanan ha??in mallaka, ana iya ba da ?arin tallafin adabi.
