Het heeft een hoog gehalte aan eiwitten en essenti\u00eble aminozuren, en de samenstelling is redelijk en evenwichtig. Het is een hoogwaardige plantaardige eiwitgrondstof in de veehouderij. Aangezien sojameel echter verschillende antinutritionele factoren bevat, vermindert het de vertering, absorptie en benutting van voedingsstoffen door vee en heeft het zelfs een negatieve invloed op de groei, ontwikkeling en gezondheid van dieren. Gefermenteerd sojameel wordt gemaakt van sojameel van hoge kwaliteit als grondstof. Het maakt gebruik van een combinatie van microbi\u00eble fermentatie en proteolytische enzymhydrolyse om veel van de antinutritionele factoren in het sojameel te verwijderen. Tegelijkertijd produceert het fermentatieproces enkele smaakstoffen zoals melkzuur en melkzuur, wat de voedingswaarde en smakelijkheid van het sojameel verbetert.<\/p>\n<p><b>1 Effect van de verhouding tussen ingredi\u00ebnten en water, temperatuur en fermentatietijd op het gehalte aan kleine peptiden in gefermenteerd sojameel<\/b><br \/>\nGefermenteerd sojameel maakt gebruik van biologische technieken zoals microbi\u00eble fermentatie en enzymtechnologie. Het gebruikt sojameel als grondstof en voegt gist, melkzuurbacteri\u00ebn, Bacillus subtilis en protease toe tijdens het fermentatieproces in vaste toestand om het gehalte aan ruwe celstof, niet-zetmeelpolysachariden en antigene eiwitten in sojameel te verminderen en zo de kwaliteit van sojameel te verbeteren.<sup>[6]<\/sup>.

Het product heeft een goede smakelijkheid en een klein peptidegehalte van 12-15%, wat kan voldoen aan de massaproductievereisten voor gefermenteerd sojameel. Na enzymatische hydrolyse met Anqi alkalische protease AP-20 heeft de gefermenteerde sojameel een gehalte aan kleine peptiden tot 16-21%, wat geschikt is voor de productie en toepassing van gefermenteerde sojameel van hoge kwaliteit met een hoog gehalte aan kleine peptiden. In dit document worden de producteigenschappen van AP-10 en AP-20 gecombineerd en toegepast op de bereiding van gefermenteerde sojameel.
