本发明提供一种基于低温超微粉碎耦合pH法提取菜籽饼粕高蛋白的方法，该方法采用饼粕原料直接进行超微技术物理改性，在减小饼粕粒径增大其比表面积的同时、改善饼粕中纤维与蛋白的作用程度，提高纤维的溶解程度，从而降低蛋白碱溶环节所需的碱液强度并保障其溶出效果。该方法工序简易、不需进行有机溶剂脱脂、碱溶液消耗量小，菜籽饼粕的超微粉碎预处理提高蛋白质溶出率、降低碱溶环节的碱性强度，在提高蛋白质品质的同时降低有机溶剂及碱的使用量，减少生产过程中碱溶液废水的排放量，制备工艺更环保。 The invention provides a method for extracting high protein of rapeseed cake meal based on a low-temperature superfine grinding coupling pH method. According to the method, cake meal raw materials are directly subjected to physical modification by a superfine technology, the particle size of the cake meal is reduced, the specific surface area of the cake meal is increased, the action degree of fibers and protein in the cake meal is improved, and the dissolution degree of the fibers is improved, so that the strength of alkali liquor required in the protein alkali dissolution link is reduced, and the dissolution effect of the alkali liquor is guaranteed. The method is simple in process, organic solvent degreasing is not needed, the consumption of the alkali liquor is low, the diss
