Ho lahleheloa ke livithamine nakong ea ts'ebetso ea lijo tsa liphoofolo tse ruuoang lapeng
Bakeng sa liprotheine, lik'habohaedreite, mafura le liminerale, ts'ebetso e na le phello e batlang e fokola ho bioavailability ea bona, athe livithamine tse ngata ha li tsitsitse ebile li na le oxidized habonolo, li bola, li senngoa kapa li lahleheloa, kahoo ts'ebetso e tla ama lihlahisoa tsa bona.E na le tšusumetso e kholoanyane;'me ts'ebetsong ea ho boloka lijo, tahlehelo ea livithamine e amana le ho tiisoa ha setshelo sa liphutheloana, bophelo ba sethala, le mocheso o potolohileng.
Nakong ea extrusion le ho ikhohomosa, ho se sebetse ha livithamine ho tla etsahala, tahlehelo ea vithamine E e qhibilihang ka mafura e ka fihla ho 70%, 'me tahlehelo ea vithamine K e ka fihla ho 60%;tahlehelo ea vithamine ea lijo tsa liphoofolo tse ruuoang lapeng le eona e batla e le kholo nakong ea polokelo, 'me tahlehelo ea livithamine tse qhibilihang ka mafura e kholo ho feta ea sehlopha sa B Livithamini, vithamine A le vithamine D3 li lahleheloa ke hoo e ka bang 8% le 4% ka khoeli;'me li-vithamine tsa B li lahleheloa ke hoo e ka bang 2% ho ea ho 4% ka khoeli.
Nakong ea ts'ebetso ea extrusion, 10% ~ 15% ea livithamine le li-pigments li lahleheloa ka karolelano.Ho boloka vithamine ho itšetlehile ka tlhahiso ea thepa e tala, ho lokisetsa le ho atolosa mocheso, mongobo, nako ea ho boloka, joalo-joalo Hangata, ho phaella ho feteletseng ho sebelisetsoa ho lefella, 'me mofuta o tsitsitseng oa vithamine C o ka boela oa sebelisoa, ho fokotsa tahlehelo ea vithamine nakong ea ho sebetsa le ho boloka. .
Joang ho fokotsa tahlehelo ea livithamine nakong ea ts'ebetso?
1. Fetola sebopeho sa lik'hemik'hale tsa livithamine tse itseng ho etsa hore e be metsoako e tsitsitseng haholoanyane;joalo ka thiamine mononitrate ho e-na le sebopeho sa eona sa mahala sa motheo, li-esters tsa retinol (acetate kapa palmitate), tocopherol Phapanyetsano ea joala le ascorbic acid phosphate sebakeng sa ascorbic acid.
2. Li-vithamine li entsoe ka microcapsules e le mokhoa o le mong.Ka tsela ena, vithamine e na le botsitso bo betere mme e ka ntlafatsa ho senyeha ha vithamine lijong tse tsoakiloeng.Li-vithamine li ka tšeloa ka gelatin, starch le glycerin (li-antioxidants li sebelisoa hangata) kapa tsa fafatsoa ka har'a li-microcapsules, 'me li lateloa ke ho roala ha starch.Tšireletso ea vithamine nakong ea ts'ebetso e ka matlafatsoa le ho feta ka ho qhekella ha li-microcapsules, mohlala, ka ho futhumatsa ho thatafatsa li-microcapsules (tseo hangata li bitsoang li-microcapsules tse amanang le sefapano).Ho hokahanya ho ka finyelloa ka karabelo ea Maillard kapa mekhoa e meng ea lik'hemik'hale.Boholo ba vithamine A e sebelisoang ke baetsi ba lijo tsa liphoofolo tsa lapeng tsa Amerika ke li-microcapsules tse amanang le sefapano.Bakeng sa livithamini tsa B tse ngata, ho omisa ho sebelisoa ho matlafatsa botsitso ba tsona le ho etsa liphofshoana tse phallang mahala.
3. Ho se sebetse ha hoo e batlang e le livithamine tsohle ho etsahala nakong ea extrusion ea lijo tsa liphoofolo tsa lapeng, 'me tahlehelo ea livithamine lijong tse entsoeng ka makotikoting e bakoa ka ho toba ke mocheso le ts'ebetso le nako ea li-ion tsa tšepe tsa mahala.Tahlehelo ka ho omisa le ho roala (ho eketsa mafura kapa ho qoelisa bokaholimo ba sehlahisoa se omisitsoeng) le tsona li itšetlehile ka nako le mocheso.
Nakong ea polokelo, mongobo, mocheso, pH le li-ion tsa tšepe tse sebetsang li ama sekhahla sa tahlehelo ea livithamine.Ho na le mefuta e sa sebetseng ea liminerale joalo ka chelates, oxides kapa carbonates ho ka fokotsa tahlehelo ea livithamini tse ngata ha li bapisoa le liminerale tse sulfate kapa mofuta oa mahala..Iron, koporo le zinki li hlahella ka ho khetheha ho ntlafatseng maikutlo a Fenton le ho hlahisa li-radicals tsa mahala.Metsoako ena e ka senya li-radicals tsa mahala ho fokotsa tahlehelo ea vithamine.Ho sireletsa mafura a lijo ho tsoa ho oxidation ke ntlha ea bohlokoa ho fokotsa tlhahiso ea li-radicals tsa mahala lijong.Ho eketsoa ha li-chelating agents tse kang ethylenediaminetetraacetic acid (EDTA), phosphoric acid, kapa synthetic antioxidants tse kang di-tert-butyl-p-cresol ho mafura li ka fokotsa moloko oa li-radicals tsa mahala.
