Indlela yokukhiqiza yendabuko ye-inositol i-pressure hydrolysis. Ngenxa yesipiliyoni seminyaka yokukhiqiza kwezimboni, indlela ye-pressure hydrolysis iwubuchwepheshe benqubo eyinhloko eyamukelwa abakhiqizi basekhaya futhi ithuthukiswe ngokuqhubekayo ekukhiqizeni. Inqubo evamile yendlela yokucindezela i-hydrolysis imi kanje: i-phytin (i-hydrolysis) → isisombululo se-hydrolysis (i-neutralization, filtration) → isisombululo se-inositol (ukususwa kokungcola nokugxila, i-crystallization centrifugation) → i-inositol eluhlaza (ukuchithwa nokususwa kokungcola, i-crystallization centrifugation) → umkhiqizo omuhle. Phakathi kwazo, i-hydrolysis nokucwengwa yizinyathelo ezimbili ezibalulekile.
I-sodium phytate hydrolysis
Ukusebenzisa amanzi afakwe ummbila njengempahla eluhlaza, i-sodium phytate ikhiqizwa indlela ye-ion exchange resin adsorption, bese ingaphansi kwengcindezi ye-hydrolysis reaction ukukhiqiza i-inositol. Ngesikhathi esifanayo nokukhiqizwa kwe-inositol, ukukhiqizwa ngokubambisana kwe-disodium hydrogen phosphate (ukukhiqizwa kwe-disodium hydrogen phosphate cishe izikhathi ezingu-12 kune-inositol) kubuyisela ngempumelelo i-organic phosphorus ezinhlamvu, okuvula indlela entsha yokubuyiselwa kwe-organic phosphorus emikhiqizweni yezolimo kanye ne-sideline.
Incazelo yenqubo yokukhiqiza: Amanzi acwiliswa ummbila akhangiswa nge-ion exchange resin ukuze kutholwe ingxube ethile yesisombululo se-sodium phytate, esingaphansi kwengcindezi ye-hydrolysis reaction ukuze kukhiqizwe inositol ne-disodium hydrogen phosphate. Ngemva kwesikhathi esithile sokusabela, impahla iyakhishwa, ihlungwe, ipholiswe, futhi ifakwe ikristalu, okuholela emvuleni yamakristalu e-disodium hydrogen phosphate. Isixazululo se-hydrolysis reaction samakristalu e-sodium dihydrogen phosphate sicwengwa ngokulandelana nge-anion kanye nezinhlaka zokushintshisana ze-cation kuze kube yilapho ukuhlangana kwama-anion nama-cations kusixazululo se-hydrolysis kufinyelela ezingeni elishiwo. Isixazululo sokuphendula se-hydrolysis esicwengekile singagxiliswa futhi sifakwe amakristalu ukuze kutholwe umkhiqizo ophelile we-inositol. Isivuno se-inositol sithinteka kakhulu yizici ezintathu: isikhathi sokuphendula i-hydrolysis, ingcindezi yokusabela nge-hydrolysis, kanye nokuhlushwa kwesisombululo se-sodium phytate. Ngokuhlolwa kwe-orthogonal, izimo zokusabela ezilungile zokusabela kwe-hydrolysis zitholwe ngale ndlela elandelayo: isikhathi se-hydrolysis samahora angu-7-8, ukuhlushwa kwe-sodium phytate ka-20%, ukucindezela kwe-hydrolysis kwe-1.5 MPa, kanye nesilinganiso sesivuno se-inositol esivela ku-0.1544% kuya ku-0.1722%. Ukuze kubhekwe umphumela wokukhulisa i-hydrolysis reactor, ukuvinjelwa kombhede embhoshongweni wokushintshana we-ion wezimboni, izinguquko kumthamo wokushintshisana, futhi kulingisa izimo zokusebenza ezinkulu zokujikeleza ezisetshenziswa esigabeni sokuvuselela imishini yezimboni, ukuhlolwa komshayeli kwenziwa kudivayisi enamandla okucubungula angu-600m/a ngaphansi kwezimo zokusabela ezingenhla. Isilinganiso sesivuno se-inositol singu-0.1601% (izikhathi ezingaphezu kuka-2.5 ngaphezu kwendlela ye-calcium phytate, futhi ikhwalithi yomkhiqizo ihlangabezana nezinkomba ezihlukahlukene ezichazwe ku-National Pharmacopoeia), ehambisana nedatha yokuhlola encane.
Indlela ye-Atmospheric pressure catalytic
I-atmospheric pressure catalytic method iyindlela entsha yokukhiqiza i-inositol esanda kuthuthukiswa futhi yafakwa ekukhiqizweni kwezimboni eShayina eminyakeni yamuva nje. I-hydrolysis yayo kanye nokucwengisiswa kwayo kunezici ezihlukile. Izici ezibalulekile:
(1) Yehlisa ngokuphawulekayo ukutshalwa kwezimali kwesikhathi esisodwa kumishini, futhi ingalondoloza ngaphezu kuka-50% wotshalomali lwempahla uma isikali silingana;
(2) Ukusetshenziswa kwe-phytin hydrolysis catalyst kufinyeza umjikelezo wokukhiqiza futhi kuthuthukise izinga lokusetshenziswa kwezinto ezingavuthiwe;
(3) Inqubo yokucwenga isithuthukisiwe, okubangele ukwanda kwekhwalithi yomkhiqizo kanye nesivuno.
Inqubo ye-Atmospheric catalytic process: Ingxenye ethile ye-catalyst (eyakhiwa i-glycerol, urea, ne-calcium carbonate) yengezwa ekuhlanganiseni okuthile kwesisombululo se-phytin kungcindezi yasemkhathini, futhi kushiselwe i-hydrolysis. Ngemuva kwe-hydrolysis, filtration, crystallization, drying, nezinye izinqubo, i-inositol ingatholakala. Ngenxa yezici zemvelo ze-catalyst, i-inositol ingenziwa ikristalu ngesikhathi esisodwa, okuholela emikhiqizweni eqediwe ephezulu futhi kube lula inqubo. Ama-Catalysts angaphinda asetshenziswe.
