From the solvent comparison test, single factor test and orthogonal test, the optimum extracting solvent and conditions were obtained to extract soybean isoflavone from defatted soybean meal.
In the condition of industrial production, orthogonal test and slab rolling comparison test were had by adding different rare earth element and alloying element.
