Soy protein cais (SPI) yog ib qho khoom siv muaj txiaj ntsig thiab cov khoom noj muaj nuj nqi uas tau muaj cov muaj suab nrov hauv kev lag luam khoom noj khoom haus vim nws cov txiaj ntsig ntau ntau thiab kev siv. Muab tau los ntawm tsawg-kub sib cais ua noj suybean, Soy protein cais tawm hauv cov txheej txheem tsis yog cov ntsiab lus uas tsis muaj protein ntau dua 90%. Qhov no ua rau nws zoo tshaj plaws ntawm cov protein zoo, tsawg hauv cov roj cholesterol thiab tsis muaj rog, ua rau nws muaj kev noj qab haus huv rau cov neeg siv khoom. Nrog nws lub peev xwm pab tau poob qis, txo cov ntshav plab, thiab tiv thaiv cov kab mob plawv, thiab cov tshuaj tiv thaiv kab mob colabrias, thiab cov protein cais tau dhau los ua cov khoom noj muaj txiaj ntsig.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov protein cais tawm yog nws txoj haujlwm hauv cov ntawv thov zaub mov. Nws muaj ntau ntau yam ntawm cov khoom muaj nuj nqi, suav nrog gelling, rydration, ras nqus, solubility, ua npuas ncauj, kev teeb tsa, thiab clumping. Cov khoom no ua rau nws muaj ntau yam khoom noj uas tuaj yeem siv tau nyob rau hauv ntau yam khoom noj khoom haus thoob plaws kev lag luam. Los ntawm cov khoom lag luam rau hmoov nplej, cov khoom noj nqaij, ua rau cov neeg tsis noj nqaij, ua rau nws cov khoom tseem ceeb hauv kev tsim cov khoom noj ntawm ntau yam khoom noj.
Muaj ntau txoj hauv kev los siv kua protein cais tawm, xws li:
(1) Qhov kev sib ntxiv kom qhuav: Ntxiv cov protein cais tawm hauv cov khoom xyaw rau hauv daim ntawv ntawm cov hmoov qhuav thiab sib tov lawv. Cov nyiaj ntxiv yog li 2% -6%;
(2) Ntxiv rau hauv daim ntawv ntawm hydr Feem ntau, 10% -30% ntawm collegoid tau ntxiv rau cov khoom;
(3) Ntxiv rau hauv daim ntawv ntawm cov protein proty: sib tov cov protein cais nrog dej thiab ntxiv cov protein los ua cov nqaij protein. Yog tias tsim nyog, xim hloov kho tau tuaj yeem ua, thiab tom qab ntawd nws yog tsim los ntawm nqaij grinder. Cov khoom protein, feem ntau ntxiv rau hauv ib qho nyiaj ntawm 5% -15%;
(4) Ntxiv rau hauv daim ntawv ntawm ib qho emulsion: sib tov protein cais nrog dej thiab roj (roj roj los yog roj zaub) thiab chop. Qhov sib xyaw sib xyaw yog kho kom haum raws li cov kev xav tau sib txawv, cov protein: 1-2 / 1: 6: 1: 1-2, thiab lwm yam piv txwv yog li 10% -30%;
(5) Ntxiv rau hauv daim ntawv ntawm kev txhaj tshuaj: sib xyaw ua kom muaj protein cais nrog dej, thiab lwm yam, thiab tom qab ntawd, thiab tom qab ntawd, thiab tom qab ntawd, thiab tom qab ntawd, thiab tom qab ntawd, thiab tom qab ntawd, thiab tom qab ntawd, thiab tom qab ntawd, thiab tom qab ntawd, thiab tom qab ntawd, thiab tom qab ntawd, thiab tom qab ntawd, thiab tom qab ntawd, thiab tom qab ntawd, thiab tom qab ntawd, thiab tom qab ntawd, thiab tom qab ntawd thiab lwm yam. Feem ntau, tus nqi ntawm cov protein ntxiv rau kev txhaj tshuaj yog li 3% -5%.
Hauv kev xaus, kua protein cais tawm muaj ntau yam ntawm kev ua haujlwm thiab kev siv hauv kev lag luam khoom noj. Nws cov ntsiab lus muaj protein ntau, txuas nrog nws cov khoom muaj nuj nqis, ua rau nws muaj cov khoom xyaw infaluable rau cov khoom noj khoom haus thiab cov yam ntxwv ua haujlwm ntawm lawv cov khoom. Txawm hais tias nws tau txhim kho kev ntxhib los mos, lossis muab cov protein zoo tshaj plaws hauv kev txhim kho tshiab thiab cov khoom noj khoom haus khoom noj muaj txiaj ntsig. Raws li cov neeg siv khoom thov kom muaj kev noj qab haus huv thiab muaj cov zaub mov muaj zog ntxiv, yog cov khoom noj tseem ceeb hauv kev tsim cov khoom noj ntau yam khoom noj.
