The invention relates to the technical field of production of agricultural products, in particular to instant health-care anti-aging soybean milk powder. During production, the following steps are carried out: carefully selecting soybeans, cleaning, proportionally uniformly mixing thearubigin, maltitol and water as sprinkling liquid, sprinkling the surface layers of the soybeans by adopting a high-pressure spray gun till the soybeans grow hypocotyls, pulping, inflating oxygen into soybean milk till a saturated state at high pressure, fully dissolving out protein in soybean residues, centrifuging to remove the residues to obtain soybean milk, adding seaweed gel, controlling the pressure of a stirring kettle to be 60-65MPa and the temperature to be 100 DEG C, stirring at high speed, performing vacuum freezing and spray drying on the soybean milk, sterilizing, and bagging to obtain the soybean milk powder. The soybean milk powder provided by the invention is light orange, and is free of a beany flavor, strong in beany fragrance, good in solubility and free of a precipitating phenomenon.
