The invention discloses a manufacturing method of a whole-bean bean product. The method comprises the following steps of: using high-quality soybeans as raw material, cleaning, removing impurity, soaking for 8-10h at room temperature, removing hard beans and incompletely soaked beans with crimped surface, draining, blanching for 1-50min, pulping with high speed in order to form a whole-bean bean product slurry with an average grain size of lower than 40micro m, homogenizing with pressure of 20MPa to 70MPa, cooking for 2-20min at 70 DEG C-100 DEG C, rapidly cooling to 0 DEG C-20 DEG C, adding a compound coagulator, mixing uniformly, keeping temperature and standing for 30-200min at 20 DEG C-95 DEG C, so as to obtain the whole-bean bean curd. With the adoption of the manufacturing method, no bean dregs is generated in the soybean milk and bean curd production processes; the nutritive materials such as proteins, fats, dietary fibers and vitamins are remained furthest in the manufactured whole-bean bean product, and the products further has excellent shape and mouth feel.
