NOVELTY - Utilization of soybean residue involves removing protein from soybean residue, drying, adding ethanol to dry soybean residue, performing alkali catalytic decomposition reaction, separating, obtaining precipitate and mother liquid, drying the precipitate, obtaining dietary fiber, aging mother liquor, rinsing oil phase with water, adding ethanol and styrene macroporous strong acid cation exchange resin catalyst, esterifying, filtering, distilling, obtaining biodiesel, adding ethyl acetate to remaining liquid, crystallizing, adding crude phytosterol to ethanol, and recrystallizing.    USE - Utilization of soybean residue for producing dietary fiber, biodiesel and phytosterol.    ADVANTAGE - The method provides phytosterol, dietary fiber and biodiesel with high purity and yield, using soybean residue.    DETAILED DESCRIPTION - Utilization of soybean residue involves removing water from wet soybean residue, crushing, removing protein from the residue by hydrolysis, drying, obtaining dry soybean residue having water content of 5-12%, adding ethanol to dry soybean residue, performing alkali catalytic decomposition reaction using alkali solution, adjusting pH of the reaction mixture to 3-5, performing solid-liquid separation, obtaining precipitate and mother liquid, drying the precipitate, obtaining dietary fiber, aging mother liquor, rinsing oil phase with water to neutral, removing excess water by distillation, adding ethanol and styrene macroporous strong acid cation exchange resin catalyst, for esterification, esterifying, filtering reaction solution, recovering catalyst, distilling a 250 degrees C, obtaining biodiesel, adding ethyl acetate, acetone and/or ethanol solvent solution to remaining liquid, crystallizing, obtaining crude phytosterol, distilling mother liquid to recover solvent, adding crude phytosterol to ethanol or ethyl acetate, recrystallizing, centrifuging, obtaining fine phytosterol, and distilling mother liquid to recover solvent. The mass ratio of esterification reaction feed solution, ethanol and catalyst is 1:0.5-6:0.05-0.5.
