Soy protein isolate (SPI) ke motsoako o feto-fetohang le o sebetsang o fumaneng botumo indastering ea lijo ka lebaka la melemo le lits'ebetso tse ngata. Ho tsoa lijong tsa soya tse nang le mocheso o tlase oa mocheso o tlase, protheine ea soya isolate e feta letoto la lits'ebetso tsa ho ntšoa le karohano ho tlosa likarolo tse seng tsa protheine, e leng se bakang protheine e fetang 90%. Sena se etsa hore e be mohloli o babatsehang oa protheine ea boleng bo holimo, e tlaase ka k'holeseterole 'me e se na mafura, e leng se etsang hore e be khetho e ntle ho bareki. Ka bokhoni ba eona ba ho thusa ho theola boima ba 'mele, ho theola lipids maling, ho fokotsa tahlehelo ea masapo, le ho thibela mafu a pelo le methapo ea pelo, protheine ea soya e itšehla thajana e fetohile motsoako oa bohlokoa lihlahisoa tse fapaneng tsa lijo.
E 'ngoe ea likarolo tsa bohlokoa tsa protheine ea soya ke ts'ebetso ea eona lits'ebetsong tsa lijo. E na le mefuta e mengata e fapaneng ea ts'ebetso, ho kenyelletsa le gelling, hydration, emulsifying, ho monya oli, ho qhibiliha, ho phophoma, ho ruruha, ho hlophisa le ho bokellana. Mehaho ena e etsa hore e be motsoako o fapaneng o ka sebelisoang lihlahisoa tse fapaneng tsa lijo liindastering tse fapaneng. Ho tloha lihlahisoa tsa nama ho ea ho lihlahisoa tsa phofo, lihlahisoa tsa metsing, le lihlahisoa tsa meroho, protheine ea soya e itšehla thajana e fana ka melemo e mengata ea ts'ebetso, e etsang hore e be karolo ea bohlokoa ha ho etsoa lijo tse fapa-fapaneng.
Ho na le mekhoa e mengata ea ho sebelisa soy protein isolate, joalo ka:
(1) Tlatsetso e omileng: Eketsa protheine ea soya e arohaneng le metsoako ka mokhoa oa phofo e omileng ebe o e kopanya. Kakaretso ea kakaretso ea chelete e ka bang 2% -6%;
(2) Eketsa ka mokhoa oa hydrated colloid: Kopanya soy protein isolate le karolo e itseng ea metsi ho etsa slurry ebe u e eketsa. Ka kakaretso, 10% -30% ea colloid e kenngoa sehlahisoa;
(3) Eketsa ka sebopeho sa likaroloana tsa protheine: Kopanya protheine ea soya e arohaneng le metsi 'me u kenye glutamine transaminase ho hokahanya protheine ho theha nama ea protheine. Haeba ho hlokahala, ho ka etsoa phetoho ea mebala, ebe e thehoa ke grinder ea nama. Likaroloana tsa protheine, ka kakaretso li eketsoa ka bongata bo ka bang 5% -15%;
(4) Eketsa ka mokhoa oa emulsion: kopanya protheine ea soya e itšehla thajana ka metsi le oli (oli ea liphoofolo kapa oli ea meroho) le ho khaola. Karolelano ea ho kopanya e lokisoa ka nepo ho latela litlhoko tse fapaneng, protheine: metsi: oli = 1: 5: 1-2 / 1: 4: 1-2 / 1: 6: 1-2, joalo-joalo, 'me karolelano ea kakaretso ke hoo e ka bang 10% -30%;
(5) Eketsa ka mokhoa oa ente: kopanya protheine ea soya e itšehla thajana le metsi, li-seasoning, marinade, joalo-joalo, ebe u e kenya ka har'a nama ka mochini oa ente ho bapala karolo ea ho boloka metsi le ho nolofatsa. Ka kakaretso, palo ea protheine e kentsoeng enteng e ka ba 3% -5%.
Qetellong, soy protein isolate e fana ka mefuta e mengata ea ts'ebetso le lits'ebetso indastering ea lijo. Likahare tsa eona tse phahameng tsa protheine, hammoho le ts'ebetso ea eona, li e etsa motsoako oa bohlokoa bakeng sa baetsi ba lijo ba batlang ho ntlafatsa boemo ba phepo e nepahetseng le litšobotsi tsa ts'ebetso ea lihlahisoa tsa bona. Ebang ke ho ntlafatsa sebopeho, ho boloka mongobo, kapa ho fana ka mohloli oa protheine ea boleng bo holimo, soy protein isolate e tsoela pele ho bapala karolo ea bohlokoa ho nts'etsopele ea lihlahisoa tsa lijo tse nang le phepo e nepahetseng. Ha tlhoko ea bareki ea lijo tse phetseng hantle le tse tšoarellang e ntse e hola, protheine ea soya e itšehla thajana e ikemiselitse ho lula e le motsoako oa bohlokoa tlhahisong ea mefuta e fapaneng ea lihlahisoa tsa lijo.
