Soy protein isolate (SPI) ndi chinthu chosunthika komanso chogwira ntchito chomwe chadziwika bwino m'makampani azakudya chifukwa cha zabwino zambiri komanso kugwiritsa ntchito kwake. Kuchokera ku chakudya chochepa cha soya chopanda kutentha, soya protein isolate imadutsa njira zingapo zochotsa ndi kupatukana kuchotsa zinthu zopanda mapuloteni, zomwe zimapangitsa kuti pakhale mapuloteni oposa 90%. Izi zimapangitsa kukhala gwero labwino kwambiri la mapuloteni apamwamba kwambiri, otsika mu cholesterol komanso opanda mafuta, zomwe zimapangitsa kukhala njira yathanzi kwa ogula. Ndi kuthekera kwake kuthandizira kuwonda, kutsitsa lipids m'magazi, kuchepetsa kuchepa kwa mafupa, komanso kupewa matenda amtima ndi cerebrovascular, kudzipatula kwa soya kwakhala chinthu chofunikira pazakudya zosiyanasiyana.
Chimodzi mwazinthu zazikulu za kudzipatula kwa protein ya soya ndikugwira ntchito pazakudya. Lili ndi zinthu zambiri zogwira ntchito, kuphatikizapo gelling, hydration, emulsifying, kuyamwa mafuta, kusungunuka, kupanga thovu, kutupa, kukonzekera, ndi kugwa. Izi zimapangitsa kuti zikhale zosunthika zomwe zitha kugwiritsidwa ntchito muzakudya zosiyanasiyana m'mafakitale osiyanasiyana. Kuchokera ku nyama kupita ku ufa, zam'madzi, ndi zamasamba, puloteni ya soya yodzipatula imapereka maubwino ambiri, ndikupangitsa kuti ikhale yofunika kwambiri popanga zakudya zosiyanasiyana.
Pali njira zambiri zogwiritsira ntchito soya protein isolate, monga:
(1) Kuwumitsa: Onjezani mapuloteni a soya odzipatula ku zosakaniza ngati ufa wouma ndikusakaniza. Kuchulukitsa kwachulukidwe kuli pafupifupi 2% -6%;
(2) Onjezani mu mawonekedwe a hydrated colloid: Sakanizani mapuloteni a soya amadzipatula ndi gawo lina la madzi kuti mupange slurry ndikuwonjezera. Nthawi zambiri, 10% -30% ya colloid imawonjezeredwa kuzinthu;
(3) Onjezani ngati tinthu tating'onoting'ono tomwe timapanga mapuloteni: Sakanizani mapuloteni a soya ndi madzi ndikuwonjezera glutamine transaminase kuti mulumikizane ndi mapuloteni kuti mupange mapuloteni a nyama. Ngati ndi kotheka, kusintha mtundu kungathe kuchitidwa, ndiyeno kumapangidwa ndi chopukusira nyama. Mapuloteni particles, ambiri anawonjezera mu kuchuluka kwa pafupifupi 5% -15%;
(4) Onjezani mu mawonekedwe a emulsion: kusakaniza soya mapuloteni kudzipatula ndi madzi ndi mafuta (nyama mafuta kapena masamba mafuta) ndi kuwaza. Chiŵerengero chosakanikirana chimasinthidwa moyenera malinga ndi zosowa zosiyanasiyana, mapuloteni: madzi: mafuta = 1: 5: 1-2 / 1: 4: 1-2 / 1: 6: 1-2, etc. pafupifupi 10-30%;
(5) Onjezani mu mawonekedwe a jekeseni: sakanizani mapuloteni a soya odzipatula ndi madzi, zokometsera, marinade, ndi zina zotero, ndiyeno muyike mu nyama ndi makina a jakisoni kuti mutengepo gawo posungira madzi ndi kutentha. Nthawi zambiri, kuchuluka kwa mapuloteni omwe amawonjezeredwa ku jakisoni ndi pafupifupi 3% -5%.
Pomaliza, kudzipatula kwa soya kumapereka magwiridwe antchito osiyanasiyana ndikugwiritsa ntchito pamakampani azakudya. Mapuloteni ake ochuluka, komanso momwe amagwirira ntchito, amapangitsa kuti ikhale yofunika kwambiri kwa opanga zakudya omwe akufuna kupititsa patsogolo kadyedwe kake komanso magwiridwe antchito azinthu zawo. Kaya ndikukonza kapangidwe kake, kusunga chinyezi, kapena kupereka gwero la mapuloteni apamwamba kwambiri, soya protein isolate imathandizira kwambiri pakupanga zakudya zatsopano komanso zopatsa thanzi. Pomwe kufunikira kwa ogula zakudya zathanzi komanso zokhazikika kukukulirakulira, kudzipatula kwa soya kwatsala pang'ono kukhala chinthu chofunikira kwambiri popanga zakudya zosiyanasiyana.
