I-soy protein isolate (SPI) iyisithako esisebenziseka kalula nesisebenzayo esithole ukuthandwa embonini yokudla ngenxa yezinzuzo zayo eziningi kanye nokusetshenziswa kwayo. Ithathwe ekudleni kwesoya okukhishwe amafutha okushisa okuphansi, i-soy protein isolate idlula ochungechungeni lwezinqubo zokukhipha nokuhlukanisa ukuze kususwe izingxenye ezingezona amaprotheni, okuholela ekuquketheni amaprotheni angaphezu kuka-90%. Lokhu kuyenza ibe umthombo omuhle kakhulu wamaprotheni asezingeni eliphezulu, aphansi ku-cholesterol futhi angenawo amafutha, okwenza kube inketho enempilo kubathengi. Njengoba inamandla okusiza ekunciphiseni isisindo, ukwehlisa amafutha egazini, ukunciphisa ukulahlekelwa amathambo, nokuvimbela izifo zenhliziyo nemithambo yegazi, i-soy protein isolate ibe isithako esibalulekile emikhiqizweni yokudla ehlukahlukene.
Esinye sezici ezibalulekile ze-soy protein isolate ukusebenza kwayo ekusetshenzisweni kokudla. Inezakhiwo eziningi ezisebenzayo, okuhlanganisa i-gelling, i-hydration, i-emulsifying, i-oil munc, i-solubility, i-foam, i-dumb, i-organize, kanye ne-clupping. Lezi zakhiwo zenza kube yisithako esiguquguqukayo esingasetshenziswa emikhiqizweni yokudla eyahlukahlukene ezimbonini ezahlukene. Kusukela emikhiqizweni yenyama kuya emikhiqizweni kafulawa, imikhiqizo yasemanzini, kanye nemikhiqizo yemifino, i-soy protein isolate inikeza izinzuzo eziningi zokusebenza, okwenza kube yingxenye ebalulekile ekwakhiweni kokudla okuhlukahlukene.
Kunezindlela eziningi zokusebenzisa i-soy protein isolate, njenge:
(1) Ukwengeza okomile: Faka i-soy protein isolate ezithakweni ngendlela yempuphu eyomile bese uyixuba. Inani elijwayelekile lokwengeza lingaba ngu-2%-6%;
(2) Faka ngendlela ye-colloid enamanzi: Hlanganisa i-soy protein isolate nengxenye ethile yamanzi ukuze wakhe i-slurry bese uyifaka. Ngokuvamile, i-10%-30% ye-colloid ifakwa kumkhiqizo;
(3) Faka ngendlela yezinhlayiya zamaprotheni: Hlanganisa isokhethi yamaprotheni e-soy namanzi bese ufaka i-glutamine transaminase ukuze uhlanganise iphrotheni ukuze yakhe inyama yamaprotheni. Uma kudingeka, ukulungiswa kombala kungenziwa, bese kwenziwa nge-grinder yenyama. Izinhlayiya zamaprotheni, ngokuvamile zengezwa ngenani elingaba ngu-5%-15%;
(4) Faka ngendlela ye-emulsion: hlanganisa i-soy protein isolate namanzi namafutha (amafutha ezilwane noma amafutha emifino) bese usika. Isilinganiso sokuxuba silungiswa ngokufanele ngokwezidingo ezahlukene, amaprotheni: amanzi: amafutha = 1:5:1-2/1:4:1-2/1:6:1-2, njll., kanti isilinganiso sokwengeza esijwayelekile singaba ngu-10%-30%;
(5) Faka ngendlela yomjovo: hlanganisa isokhethi ye-soy protein namanzi, izinongo, i-marinade, njll., bese uyijova enyameni ngomshini wokujova ukuze udlale indima ekugcineni amanzi kanye nokuthamba. Ngokuvamile, inani le-protein elingeziwe kumjovo lingaba ngu-3%-5%.
Ekuphetheni, i-soy protein isolate inikeza imisebenzi eminingi kanye nezicelo embonini yokudla. Okuqukethwe kwayo okuphezulu kwamaprotheni, kanye nezakhiwo zayo zokusebenza, kuyenza ibe yisithako esibalulekile kubakhiqizi bokudla abafuna ukuthuthukisa iphrofayili yokudla kanye nezici zokusebenza kwemikhiqizo yabo. Kungakhathaliseki ukuthi ukuthuthukisa ukuthungwa, ukuthuthukisa ukugcinwa komswakama, noma ukunikeza umthombo wamaprotheni asezingeni eliphezulu, i-soy protein isolate iyaqhubeka nokudlala indima ebalulekile ekuthuthukisweni kwemikhiqizo yokudla emisha nenempilo. Njengoba isidingo sabathengi sezinketho zokudla ezinempilo neziqhubekayo siqhubeka nokukhula, i-soy protein isolate ikulungele ukuhlala iyisithako esibalulekile ekwakhiweni kwemikhiqizo yokudla eyahlukahlukene.
