I-Saccharification linyathelo elibalulekileyo le-biochemical kwi-inkqubo yokwenza i-sakeIguqula istatshi esigcinwe erayisini sibe ziishukela ezivundiswayo, ikakhulu iglucose kunye nemaltose, ezisebenza njengezinto ezisetyenziswa kwimvubelo ngexesha lokuvundiswa. Olu tshintsho luqhutywa zii-enzymes eziveliswa yi-koji mold (Aspergillus oryzae) ngexesha lokwenza i-koji—inkqubo esisiseko eyandulela ukuvundiswa kwe-sake yokwenyani.
Ukuchaza iSaccharification kwiSake Brewing
- Ukwahlulwa kwe-saccharification kwenzeka xa umsebenzi we-enzymatic uqhekeza isitatshi serayisi sibe ziishukela ezilula.
- Ukulima i-Koji mold kuvelisa ii-enzymes ezibalulekileyo, ikakhulu ii-α-glucosidases (AgdA, AgdB), i-amylase, kunye ne-protease, ezenza kube lula ukwenziwa kwe-starch hydrolysis.
- Le nkqubo iqala ngexesha lokufutha irayisi kunye nokubiliswa kwekoji, iqhubekela phambili ekulungisweni kwe-moromi mash, apho i-enzymatic saccharification iqhubeka kunye nokuveliswa kotywala obuqhutywa yi-yeast.
- Uphuhliso lweencasa: I-Saccharification inefuthe ngokuthe ngqo kwiprofayili ye-aromatic kunye nencasa ye-sake. Umsebenzi we-enzyme ulawula ukuveliswa kwee-compounds eziphambili eziguquguqukayo, ezifana ne-isoamyl acetate, enika amanqaku eziqhamo. Iintlobo ze-yeast ezinezinga eliphezulu le-saccharification, okanye ii-mutants ezenziwe ngobunjineli ezifana ne-hia1, zivelisa i-isoamyl acetate engaphezulu—ukuya kuthi ga kwi-2.6 yenani lomzali, ingakumbi xa kusetyenziswa irayisi ecoliweyo kakhulu.
- Ukuphucula isivuno: Ukuqhekeka kwesitatshi okusebenzayo kwandisa i-substrates zokubilisa, okukhokelela kwimveliso ephezulu yotywala. Umlinganiselo olawulwayo weSaccharomyces cerevisiae kunye neAspergillus oryzae uphumela ekuphumeni kwe-ethanol ephuculweyo kunye nokwakheka kwencasa elinganiselayo.
- Uzinzo lweMveliso: Umgangatho kunye nokwakheka kwee-oligosaccharides kunika uzinzo kwimveliso yokugqibela. Ii-enzymes ze-saccharification ezifana ne-AgdA zivumela ukwenziwa kwee-glycosides ezintsha (umz., i-diglucopyranosylglycerol), ezinokuchaphazela uzinzo lweekhemikhali ze-sake kunye nokuvakalelwa komlomo.

Uphuculo lwetekhnoloji olufana ne-double saccharification lunokwandisa kakhulu umxholo weswekile esebenzayo (i-isomaltose), okukhokelela ekwandeni okuphinda kuvele kunye nolawulo oluphuculweyo lwenkqubo.
- Iziphumo zoMgangatho: Ukusasazwa okungaguqukiyo kuyingozi yokungavuthwa kakuhle, iincasa ezingezizo, okanye utywala obungasebenziyo. Utshintsho lwenkqubo, olufana nokujonga ngexesha langempela uxinano lwerayisi etyumkileyo kunye nolawulo lokongeza amanzi, lusetyenziswa kakhulu kulawulo lwenkqubo yokusasazwa. Ezi ndlela zinceda ukuqinisekisa ukuba umsebenzi we-enzyme kunye nokuqhekeka kwe-substrate kuqhubeka ngokufanelekileyo, kugcina i-bouquet ecetywayo, imvakalelo yomlomo, kunye nozinzo.
Imizekelo yokoyisa le mingeni ibandakanya:
- Ukusebenzisa i-multivariate spectroscopy ukulinganisa iswekile ngexesha langempela ngexesha lokwenziwa kwebhiya, okuvumela uhlengahlengiso olukhawulezileyo.
- Ukusebenzisa uhlalutyo lolawulo lwenkqubo ukulandelela i-pH kunye nobushushu, okukhokela zombini ukuvunwa kwee-enzyme kunye nexesha lokubilisa.
- Ukwamkela iiprotokholi ze-double saccharification, ezinokunyusa umxholo we-isomaltose, zongeze iimpawu zesondlo, kwaye zigcine iiprofayili zemveliso ezihambelanayo.
Ngamafutshane, i-saccharification linyathelo eliphambili elifuna iindlela ezichanekileyo zokwenziwa kwe-sake. Ukusetyenziswa kwee-enzyme eziphambili ekwenzeni i-sake, ukukhetha ngononophelo irayisi, kunye namaqhinga okuphucula imveliso ye-saccharification kwi-sake kubalulekile ukuze kufunyanwe iincasa eziphezulu, isivuno esiphezulu, kunye nomgangatho ohambelanayo. I-saccharification ephuculweyo ixhasa iindlela zemveli nezanamhlanje zokulawula inkqubo yokubilisa i-sake, iseka isiseko sesiphumo sonke sokwenza i-sake.
Ukuqonda iRice Crushed Slurry kwiNkqubo yokuBilisa iSake
Ukwakhiwa kunye nokulungiswa kweRayisi eCrushed Slurry
Irayisi ecoliweyo yimithombo esisiseko kwinkqubo yokwenza i-sake, eyenziwe ngokuxuba irayisi ye-sake egayiweyo ngokukodwa namanzi. I-slurry eqhelekileyo inemilinganiselo eyahlukeneyo ye-rayisi eqinileyo namanzi, emiselwa ngumlinganiselo werayisi namanzi kunye nendlela yokucubungula. Uhlobo lwerayisi, olufana neHakutsurunishiki, luchaphazela kakhulu indlela esebenza ngayo i-slurry. Ulwakhiwo lweenkozo zeHakutsurunishiki lubonelela ngokufunxwa kwamanzi okuphezulu kunye nokufikeleleka kwee-enzyme, okuphucula ukusebenza kakuhle kwe-saccharification kwaye kukhokelela kwi-sake esemgangathweni ophezulu. Ukutyumza kunye nokutyumza kutshintsha ubungakanani beenkozo, indawo yomphezulu, kunye nokuqina kodonga lweseli, okwenza kube lula ukufuma okungcono kunye nokusebenzisana okusebenzayo nee-enzymes ze-enzyme ngexesha le-saccharification. Inqanaba lokutyumza lichaphazela ngokuthe ngqo indlela i-starch ekhutshwa ngayo ngokukhawuleza kwaye yenziwe ifikeleleke kwii-enzymes ze-saccharification.
Iindlela zokulungiselela ziquka amaxesha aqhelekileyo okuntywila kunye namaqondo obushushu, alinganiswe ukuze kukhuthazwe i-gelatinization efanelekileyo yesitatshi. Ukungenelela koomatshini okufana nokusila okucolekileyo okanye i-homogenization yoxinzelelo oluphezulu kunokulungisa i-viscosity kwaye kuqinisekise ukusasazeka okufanayo kwamasuntswana erayisi—izinto ezibalulekileyo ekusebenzeni kwee-enzyme kunye neziphumo zemveliso.
Ubudlelwane Phakathi Komlinganiselo Werayisi Namanzi, Ubuninzi Beslurry, kunye Nokufikeleleka Kwesitatshi
Uxinano lwe-slurry, oluchazwa kukuxinana kwezinto eziqinileyo zerayisi ezixhonywe emanzini, lulawulwa ikakhulu ngumlinganiselo werayisi namanzi. Umlinganiselo ophezulu ukhokelela kwi-slurry ezixineneyo, ezigcina i-substrate engaphezulu yokuguqulwa kwe-enzyme kodwa zinciphisa ukulula kokuxuba kunye nokusasazwa kwee-enzyme. Ukusila ixesha elide kwandisa amandla erayisi okufunxa amanzi, ngelixa ukongezwa kwamanzi amaninzi kukhuthaza ukutsalwa kwe-amylose kunye neeproteni; nangona kunjalo, ayitshintshi umxholo we-amylose ongaphakathi.
Umlinganiselo ofanelekileyo wamanzi erayisi ukhethwa ngononophelo kwiindlela eziphambili zokwenziwa kwesache ukuze kulinganiswe ukufuma, i-gelatinization, kunye nokufikelela kwi-enzyme. Amanzi amaninzi ayayinyibilikisa i-substrate, nto leyo enokunciphisa ukufunxwa kwesache, ngelixa amanzi amancinci kakhulu enyusa uxinano lwe-slurry—kunye ne-viscosity—okuthintela ukudluliselwa kobunzima kunye nokuhamba kwe-enzyme. Umzekelo, unyango lwangaphambi kokuqhuma komphunga kwi-210°C imizuzu eli-10 luphucula ukufumaneka kwesitatshi kwi-enzyme hydrolysis. Unyango lweekhemikhali olufana ne-2% NaOH lukwabonisa ukwanda kwesivuno sesache (ukuya kuthi ga kwi-60.75%), nangona ezi ndlela zixhaphake kakhulu kwi-bioethanol yemizi-mveliso kunokwenza isache yobugcisa.
Impembelelo yokuguquguquka kweempawu ze-Slurry kwi-Saccharification Enzyme Action
Iienzymes ze-saccharification for sake brewing, ikakhulu i-α-amylase kunye ne-glucoamylase, zisebenza kwisitatshi serayisi esifakwe i-gelatinized ukuvelisa iiswekile ezinokubila.

Izinto ekufuneka ziqwalaselwe kwi-enzymes kwi-Enhanced Saccharification Sake
Ii-Enzymes eziphambili ezibandakanyeka kwi-Saccharification kwiMveliso yeSake
Kwinkqubo yokwenza i-sache, ukuphucula ukusebenza kakuhle kwe-saccharification kuxhomekeke ekusebenziseni ii-enzymes eziphambili ezivela kwi-Aspergillus oryzae. Ii-enzymes eziphambili ze-saccharification ze-sache brewing ziquka:
- i-α-Amylase:Le enzyme esebenza nge-endo-acting ikhawuleza i-hydrolyze i-α-1,4-glycosidic bonds yangaphakathi kwi-rice starch, iwaphule abe yi-dextrins ezincinci kunye ne-oligosaccharides.
- I-Glucoamylase:Isebenza ngaphandle, i-glucoamylase inokwahlukanisa zombini ii-α-1,4 kunye ne-α-1,6 linkages, iguqule ii-dextrins ngqo zibe yi-glucose, nto leyo ibalulekileyo ekuvuthweni kwe-yeast.
- I-Pullulanase:I-Pullulanase ijolise ngokukodwa kwiindawo zesebe ze-α-1,6-glycosidic kwi-amylopectin, nto leyo enceda ukuwohloka ngokupheleleyo kwesitatshi kwaye ivumele i-glucoamylase ukuba isebenze ngokufanelekileyo.
- ii-α-Glucosidases (umz., i-AgdA kunye ne-AgdB):Ezi enzymes zinyibilikisa iintsalela zeglucose ezisekupheleni ezivela kwi-oligosaccharides. Izifundo zakutshanje zibonise indima yazo ebalulekileyo ekumiseleni ukwakheka kwe-oligosaccharide kwi-sake mash, zichaphazela isivuno se-saccharification kunye neprofayili yencasa yokugqibela.
