Mokhoa o tloaelehileng oa tlhahiso ea inositol ke khatello ea hydrolysis. Ka lebaka la lilemo tsa boiphihlelo ba tlhahiso ea indasteri, mokhoa oa khatello ea hydrolysis ke mokhoa o ka sehloohong oa ts'ebetso o amohetsoeng ke bahlahisi ba malapeng mme o ntse o ntlafatsoa khafetsa tlhahisong. Mokhoa o akaretsang oa mokhoa oa khatello ea hydrolysis ke o latelang: phytin (hydrolysis) → tharollo ea hydrolysis (neutralization, filtration) → tharollo ea inositol (ho tlosa lit?ila le mahloriso, crystallization centrifugation) → crude inositol (ho qhibiliha le ho tlosoa ha lit?ila, crystallization centrifugation) → sehlahisoa se setle. Har'a tsona, hydrolysis le ho hloekisa ke mehato e 'meli ea bohlokoa.
Sodium phytate hydrolysis
Ho sebelisa metsi a kolobisitsoeng ka poone e le lintho tse tala, sodium phytate e hlahisoa ke mokhoa oa adsorption oa ion exchange resin, ebe o tlas'a khatello ea hydrolysis reaction ho hlahisa inositol. Ka nako e ts'oanang le ho hlahisa inositol, tlhahiso e kopanetsoeng ea disodium hydrogen phosphate (tlhahiso ea disodium hydrogen phosphate e ka bang makhetlo a 12 ho feta inositol) ka katleho e khutlisa phosphorus ea tlhaho ho tloha lijong, ho bula tsela e ncha ea ho hlaphoheloa ha phosphorus ea tlhaho lihlahisoa tsa temo le tse ka thōko.
Tlhaloso ea ts'ebetso ea tlhahiso: Metsi a kolobisang poone a khabisitsoe ka resin ea ion ho fumana motsoako o itseng oa sodium phytate solution, e tlas'a khatello ea hydrolysis reaction ho hlahisa inositol le disodium hydrogen phosphate. Kamora nako e itseng ea karabelo, thepa e ea nt?oa, ea tlhotluoa, ea phopholetsoa, ??'me ea khabisoa, e bakang pula ea likristale tsa disodium hydrogen phosphate. Tharollo ea karabelo ea hydrolysis ea likristale tsa sodium dihydrogen phosphate e hloekisoa ka tatellano ka li-anion le li-resin tsa cation ho fihlela mahloriso a li-anion le cations tharollong ea hydrolysis e fihla maemong a boletsoeng. Tharollo e hloekisitsoeng ea hydrolysis reaction e ka tsepamisoa le ho khabisoa ho fumana sehlahisoa se felileng sa inositol. Sehlahisoa sa inositol se angoa haholo ke lintlha tse tharo: nako ea hydrolysis reaction, hydrolysis reaction pressure, le concentration ea sodium phytate solution. Ka liteko tsa orthogonal, maemo a nepahetseng a karabelo ea hydrolysis a fumanoe ka tsela e latelang: nako ea hydrolysis ea lihora tse 7-8, mahloriso a sodium phytate ea 20%, khatello ea hydrolysis ea 1.5 MPa, le chai e tloaelehileng ea inositol ho tloha ho 0.1544% ho ea ho 0.1722%. Bakeng sa ho bona phello ea matlafatso ea hydrolysis reactor, ho koaloa ha bethe ka har'a tora ea phapanyetsano ea ion ea indasteri, liphetoho tsa matla a phapanyetsano, le ho etsisa maemo a maholo a ts'ebetso ea potoloho a sebelisoang mothating oa nchafatso ea lisebelisoa tsa indasteri, tlhahlobo ea sefofane e ile ea etsoa sesebelisoa se nang le matla a ho sebetsa a 600m / a tlasa maemo a kaholimo a karabelo. Kakaretso ea lihlahisoa tsa inositol ke 0.1601% (ka makhetlo a fetang 2,5 ho feta mokhoa oa calcium phytate, 'me boleng ba sehlahisoa bo kopana le mat?oao a sa t?oaneng a boletsoeng ho National Pharmacopoeia), e lumellanang le lintlha tse nyenyane tsa tlhahlobo.
Atmospheric pressure catalytic method
The atmospheric pressure catalytic method ke mokhoa o mocha oa ho hlahisa inositol e sa tsoa hlahisoa le ho kenngoa tlhahiso ea indasteri Chaena lilemong tsa morao tjena. Hydrolysis ea eona le ho e hloekisa li na le lit?obotsi tse ikhethang. Lintlha tsa bohlokoa:
(1) Ho fokotsa haholo matsete a nako e le 'ngoe ho thepa,' me e ka boloka chelete e fetang 50% ea matsete a thepa ha tekanyo e lekana;
(2) T?ebeliso ea phytin hydrolysis catalyst e khutsufatsa potoloho ea tlhahiso le ho ntlafatsa sekhahla sa t?ebeliso ea lihlahisoa tse tala;
(3) Mokhoa oa ho hloekisa o ntlafalitsoe, o fella ka keketseho ea boleng ba sehlahisoa le lihlahisoa.
Atmospheric pressure catalytic process: Karolo e itseng ea catalyst (e entsoeng ka glycerol, urea, le calcium carbonate) e eketsoa motsoakong o itseng oa tharollo ea phytin khatellong ea sepakapaka, ebe e futhumatsoa bakeng sa hydrolysis. Kamora hydrolysis, filtration, crystallization, ho omisa le lits'ebetso tse ling, inositol e ka fumanoa. Ka lebaka la lit?oaneleho tsa tlhaho tsa catalyst, inositol e ka khabisoa ka nako e le 'ngoe, ea fella ka lihlahisoa tse felileng tsa boleng bo holimo le ho nolofatsa ts'ebetso. Li-catalyst li ka sebelisoa hape.
