The invention discloses a method for extracting micro-endosperm ultra-high oil corn cake protein. The method includes four steps of crushing, alkali-soluble acid precipitation, dialysis, vacuum freeze drying and the like. After the micro-endosperm ultra-high oil corn is pressed into oil, the remaining pressed cake is taken as a raw material, and the high-quality micro-endosperm ultra-high oil corn cake protein powder is obtained after the steps of crushing, alkali-soluble acid precipitation, dialysis and vacuum freeze drying in sequence, so that the comprehensive utilization rate of the micro-endosperm ultra-high oil corn is effectively improved; and moreover, the method is easy to operate, simple in process, low in waste water treatment cost and less in environmental damage, and is suitable for industrial production of large-scale recovery of micro-endosperm ultra-high oil corn cake protein. 本发明公开了一种提取微胚乳超高油玉米饼蛋白的方法，其包括破碎、碱溶酸沉、透析、真空冷冻干燥等四个步骤，在微胚乳超高油玉米经过压榨制油之后，取剩下的压榨饼作为原料，依次经过破碎、碱溶酸沉、透析和真空冷冻干燥步骤后得到高品质的微胚乳超高油玉
