The invention provides a making method for natural fructosan fruit and vegetable soybean milk powder. The method comprises the following steps: (1) grinding soybeans into pulp, namely drying and dehulling soybeans at a low temperature, adding water, heating, performing enzyme deactivation, regulating the pH value to be 6.8-7.0, grinding soybeans into pulp and separating residues, and deodorizing the soybean milk stock solution, thereby obtaining soybean milk; (2) making concentrated carrot juice, namely taking and washing carrots, draining water, adding purified water for pulping, performing accurate grinding, filtering, concentrating, sterilizing, thereby obtaining the concentrated carrot juice for later use; (3) taking 80-87 mass parts of the soybean milk in the step (1), 1-8 mass parts of inulin, 1-3 mass parts of the concentrated carrot juice in the step (2), 1-5 mass parts of concentrated papaya juice, 3-10 mass parts of white granulated sugar and 5-15 mass parts of malt syrup, uniformly mixing, filtering and homogenizing; and (4) concentrating and sterilizing the mixed solution homogenized in the step (3), and then performing spray drying, thereby obtaining the natural fructosan fruit and vegetable soybean milk powder. According to the invention, fine and smooth taste of the soybean milk powder is guaranteed, and the inulin is added to effectively supplement soluble dietary fibers.
