I-Soy protein isolate (SPI) iyisithako esisebenza ngezindlela eziningi futhi esisebenzayo esithole ukuduma embonini yokudla ngenxa yezinzuzo zayo eziningi kanye nokusetshenziswa kwayo. Isuselwa ekudleni kukabhontshisi wesoya oncishisiwe onezinga eliphansi lokushisa, i-soy protein isolate idlula uchungechunge lwezinqubo zokukhipha kanye nokuhlukanisa ukuze kukhishwe izingxenye ezingezona amaprotheni, okuholela ekuqukethe amaprotheni angaphezu kwama-90%. Lokhu kuyenza ibe umthombo omuhle kakhulu wamaprotheni ekhwalithi ephezulu, i-cholesterol ephansi futhi ingabi namafutha, okwenza kube inketho enempilo kubathengi. Ngamandla ayo okusiza ekunciphiseni isisindo, ukunciphisa i-lipids yegazi, ukunciphisa ukulahleka kwamathambo, nokuvimbela izifo zenhliziyo nemithambo yegazi, i-soy protein isolate isibe isithako esibalulekile emikhiqizweni ehlukahlukene yokudla.
Esinye sezici ezibalulekile ze-soy protein isolate ukusebenza kwayo ekusetshenzisweni kokudla. Inezinto eziningi ezisebenzayo, ezihlanganisa i-gelling, i-hydration, i-emulsifying, ukumunca uwoyela, ukuncibilika, ukugwaza, ukuvuvukala, ukuhlela, nokuhlanganisa. Lezi zakhiwo zikwenza kube isithako esisebenza ngezindlela eziningi esingasetshenziswa emikhiqizweni yokudla eyahlukene ezimbonini ezahlukene. Kusukela emikhiqizweni yenyama kuya emikhiqizweni kafulawa, imikhiqizo yasemanzini, nemikhiqizo yemifino, i-soy protein isolate inikeza inqwaba yezinzuzo zokusebenza, okwenza kube yingxenye ebalulekile ekwakhiweni kwezinto ezihlukahlukene zokudla.
Kunezindlela eziningi zokusebenzisa i-soy protein isolate, njenge:
(1) Ukwengeza okomile: Engeza iphrotheni ye-soy isolate ezithakweni ngendlela yempushana eyomile bese uzixuba. Isamba esengeziwe esijwayelekile singaba ngu-2% -6%;
(2) Engeza ngendlela ye-hydrated colloid: Hlanganisa i-soy protein isolate nengxenye ethile yamanzi ukuze wenze i-slurry bese uyengeza. Ngokuvamile, i-10% -30% ye-colloid yengezwa kumkhiqizo;
(3) Engeza ngesimo sezinhlayiya zamaprotheni: Hlanganisa iphrotheni ye-soy isolate namanzi bese wengeza i-glutamine transaminase ukuze unqamule iphrotheni ukuze wenze inyama yamaprotheni. Uma kunesidingo, ukulungiswa kombala kungenziwa, bese kwakhiwa nge-grinder yenyama. Izinhlayiya zamaprotheni, ngokuvamile zengezwe ngenani elingaba ngu-5% -15%;
(4) Engeza ngendlela ye-emulsion: hlanganisa i-soy protein isolate ngamanzi namafutha (amafutha ezilwane noma amafutha emifino) bese unquma. Isilinganiso sokuxuba silungiswa ngendlela efanele ngokwezidingo ezahlukene, amaprotheni: amanzi: amafutha = 1:5:1-2/1:4:1-2/1:6:1-2, njll., kanye nesilinganiso sokwengeza esijwayelekile cishe 10% -30%;
(5) Engeza ngendlela yomjovo: hlanganisa iphrotheni yesoya ihlukanise namanzi, isinongo, i-marinade, njll., bese uyijova enyameni ngomshini womjovo ukuze ubambe iqhaza ekugcineni amanzi kanye nokuthambisa. Ngokuvamile, inani lamaprotheni elifakwe emjovweni lilinganiselwa ku-3% -5%.
Sengiphetha, i-soy protein isolate inikezela ngezinhlelo eziningi zokusebenza nezinhlelo zokusebenza embonini yokudla. Okuqukethwe kwayo kwamaprotheni amaningi, okuhambisana nezici zayo zokusebenza, kuyenza ibe isithako esiyigugu kubakhiqizi bokudla abafuna ukuthuthukisa iphrofayili yokudla okunempilo kanye nezici zokusebenza zemikhiqizo yabo. Kungakhathaliseki ukuthi ukuthuthukisa ukuthungwa, ukuthuthukisa ukugcinwa komswakama, noma ukunikeza umthombo wephrotheni yekhwalithi ephezulu, i-soy protein isolate iyaqhubeka nokubamba iqhaza elibalulekile ekuthuthukisweni kwemikhiqizo yokudla emisha futhi enomsoco. Njengoba isidingo sabathengi sezinketho zokudla okunempilo nokusimeme sikhula, i-soy protein isolate isilungele ukuhlala isithako esibalulekile ekwakhiweni kwezinhlobonhlobo zemikhiqizo yokudla.
