The invention provides DHA algae oil microcapsule powder and a preparation method thereof. The preparation method comprises the following steps of blending DHA algae oil with vegetable fat in proportion to prepare mixed fat in which the mass ratio of saturated fatty acids to monounsaturated fatty acids to polyunsaturated fatty acids is 1 to (1-1.5) to (1-1.5), using the mixed fat as a core material, and performing microcapsule entrapping treatment to prepare microcapsule powder, wherein the DHA is 4-10% of total weight of microcapsules. An emulsifying agent and an antioxidant are added to themicrocapsule powder, wherein protein and a carbohydrate wall material are 60-78.8% of the total weight of the microcapsules, the mixed fat is 20-35% of the total weight of the microcapsules, the emulsifying agent is 1-3% of the total weight of the microcapsules, and the antioxidant is 0.2-2.0% of the total weight of the microcapsules. Through a microcapsule entrapping technique, various fat components required by human bo
