The invention discloses a bean seed germ soybean milk belonging to the technical field of processing of functional drinks in the food industry. The bean seed germ soybean milk is prepared from soybeans, black soya beans, azuki beans, mung beans, petits pois, and peas and is prepared by adopting the steps: firstly, cleaning the bean seeds, soaking, sprouting, carrying out defibrination, cooking, adding taurine capable of facilitating the development of the brain and the improvement of the vision function, and adding a sweetening agent or other flavoring agents. A human body is not capable of synthesizing vitamin C, the vitamin C has to be absorbed by means of foods, and is capable of greatly improving the resistance of the human body and preventing multiple diseases of scurvy and gingival bleeding, thereby being a nutrient substance necessary for the human body; germs of the bean seeds also contain certain special substances while containing nutrients contained in common vegetables so as to play a special health-care role. According to the germ soybean milk, the defect that a conventional bean food does not contain the natural vitamin C is overcome, and the defect that the edible bean food easily causes flatulence is overcome. Due to germination and sprouting of the seeds, the content of phytate is reduced, and iron is favorably absorbed. The content of protein is greatly increased through germination of the germinated bean seeds, and the protein becomes the active protein so as to be extremely easily absorbed and utilized by a human body.
