Indlela yemveli yokuvelisa i-inositol yi-pressure hydrolysis. Ngenxa yeminyaka yamava emveliso yeshishini, indlela yoxinzelelo lwe-hydrolysis yeyona nkqubo iphambili yetekhnoloji eyamkelwa ngabavelisi basekhaya kwaye iphuculwe ngokuqhubekayo kwimveliso. Inkqubo eqhelekileyo yendlela yoxinzelelo lwe-hydrolysis yile ilandelayo: i-phytin (i-hydrolysis) → isisombululo se-hydrolysis (i-neutralization, i-filtration) → isisombululo se-inositol (ukususwa kokungcola kunye nokugxininiswa, i-crystallization centrifugation) → i-inositol ekrwada (i-dissolution kunye nokukhutshwa kokungcola, i-crystallization centrifugation) → imveliso emihle. Phakathi kwazo, i-hydrolysis kunye nokucocwa ngamanyathelo amabini abalulekileyo.
I-sodium phytate hydrolysis
Ukusebenzisa amanzi ombona afakwe emanzini njengezinto eziluhlaza, i-sodium phytate iveliswa yi-ion exchange resin adsorption indlela, kwaye emva koko iphantsi koxinzelelo lwe-hydrolysis reaction ukuvelisa i-inositol. Ngexesha elifanayo nokuvelisa i-inositol, ukuveliswa kwe-disodium hydrogen phosphate (ukuveliswa kwe-disodium hydrogen phosphate malunga namaxesha angama-12 e-inositol) ibuyisela ngokufanelekileyo i-phosphorus ephilayo kwiinkozo, ivula indlela entsha yokubuyisela i-organic phosphorus kwimveliso yezolimo kunye ne-sideline.
Inkcazo yenkqubo yokuvelisa: Amanzi okufunxa umbona adsorbed nge-ion exchange resin ukuze afumane ingxinano ethile yesisombululo sesodium phytate, ephantsi koxinzelelo lwe-hydrolysis reaction ukuvelisa inositol kunye ne-disodium hydrogen phosphate. Emva kwexesha elithile lokuphendula, izinto eziphathekayo ziyakhutshwa, zihluzwe, zipholile, kwaye zenziwe ngekristali, okukhokelela kwimvula yeekristale ze-disodium hydrogen phosphate. Isisombululo se-hydrolysis reaction ye-sodium dihydrogen phosphate crystals sisulungekiswa ngokulandelelana ngokusebenzisa i-anion kunye ne-cation exchange resins de ukuxinwa kwee-anion kunye ne-cations kwisisombululo se-hydrolysis reaction sifikelela kumgangatho ochaziweyo. Isisombululo esilungisiweyo se-hydrolysis reaction sinokugxininiswa kunye ne-crystallized ukufumana imveliso egqityiweyo inositol. Isivuno se-inositol sichaphazeleka kakhulu zizinto ezintathu: ixesha lokuphendula i-hydrolysis, uxinzelelo lwe-hydrolysis reaction, kunye noxinzelelo lwesisombululo se-sodium phytate. Ngokusebenzisa iimvavanyo ze-orthogonal, iimeko ezifanelekileyo zokusabela kwi-hydrolysis reaction zafunyanwa ngolu hlobo lulandelayo: ixesha le-hydrolysis yeeyure ze-7-8, ukuxinwa kwe-sodium phytate ye-20%, uxinzelelo lwe-hydrolysis ye-1.5 MPa, kunye ne-avareji yesivuno se-inositol ukusuka kwi-0.1544% ukuya kwi-0.1722%. Ukuze kugcinwe isiphumo sokukhulisa i-hydrolysis reactor, ukuvaleka kwebhedi kwi-industrial ion exchange tower, utshintsho kumandla otshintshiselwano, kunye nokulinganisa iimeko zokusebenza zokujikeleza okukhulu ezisetyenziswa kwisigaba sokuhlaziywa kwezixhobo zoshishino, uvavanyo lokulinga lwenziwa kwisixhobo esinomthamo wokucubungula we-600m / a phantsi kweemeko zokusabela ezingentla. Umyinge wesivuno se-inositol ngu-0.1601% (ngaphezu kwama-2.5 amaxesha aphezulu kunendlela ye-calcium phytate, kwaye umgangatho wemveliso udibana nezalathisi ezahlukahlukeneyo ezichazwe kwi-National Pharmacopoeia), ehambelana nedatha yovavanyo oluncinci.
Uxinzelelo lwe-atmospheric catalytic method
Uxinzelelo lwe-atmospheric catalytic method yindlela entsha yokuvelisa i-inositol esanda kuphuhliswa kwaye ifakwe kwimveliso yezoshishino e-China kwiminyaka yamuva. I-hydrolysis yayo kunye nokucocwa kuneempawu ezizodwa. Iimpawu ezibalulekileyo:
(1) Ukunciphisa ngokuphawulekayo utyalo-mali lwexesha elinye kwizixhobo, kwaye kunokonga ngaphezu kwe-50% yotyalo-mali lwezixhobo xa isikali sinye;
(2) Ukusetyenziswa kwe-phytin hydrolysis catalyst kunciphisa umjikelezo wemveliso kunye nokuphucula izinga lokusetyenziswa kwezinto eziluhlaza;
(3) Inkqubo yokucoca iphuculwe, ibangele ukwanda komgangatho wemveliso kunye nesivuno.
Inkqubo ye-Atmospheric catalytic process: Inxalenye ethile ye-catalyst (ehlanganiswe ne-glycerol, urea, kunye ne-calcium carbonate) yongezwa kwi-concentration ethile yesisombululo se-phytin kuxinzelelo lwe-atmospheric, kwaye ishushu kwi-hydrolysis. Emva kwe-hydrolysis, i-filtration, i-crystallization, ukomisa, kunye nezinye iinkqubo, i-inositol inokufumaneka. Ngenxa yeempawu zendalo ze-catalyst, i-inositol inokubonakaliswa ngexesha elinye, okukhokelela kwimveliso ephezulu egqityiweyo kunye nokwenza lula inkqubo. IiCatalysts zinokuphinda zisetyenziswe.
