The wheat germ solid granules are characterized by being prepared by taking wheat germ supernatant as a raw material, adding okra pectin, milk powder, white granulated sugar, sucrose fatty acid ester, Arabic gum and gelatin as auxiliary materials, uniformly mixing and carrying out high-pressure homogenization, spraying and drying, wherein the wheat germ supernatant is obtained by carrying out wheat germ enzyme inactivation, ultrafine pulverization, enzymolysis and slurry-dreg separation. The wheat germ solid granules prepared by the preparation method have a powdery appearance and are milk white; and the wheat germ solid granules have a wheat germ flavor, a smooth mouthfeel and moderate sweetness and have the characteristics of abundant nutrients, convenience for drinking, relatively long shelf life and the like.
