The invention belongs to the technical field of production of dairy products, and in particular, relates to an efficient-absorption oligopeptide formula goat milk powder and a preparation method thereof. The oligopeptide formula goat milk powder is composed of the components in parts by weight: 500-800 parts of raw goat milk, 5-20 parts of corn oligopeptide, 7-25 parts of wheat oligopeptide, 8-24 parts of soybean peptide, 0.5-7 parts of phytosterol, 0.5-8 parts of inulin, 0.05-0.2 part of calcium carbonate, 0.05-0.15 part of ferrous sulfate, 0.05-0.1 part of zinc sulfate, 0.05-0.1 part of VA, 0.01-0.05 part of VB, 0.05-0.15 part of VC, 0.05-0.15 part of VD, and 0.05-0.1 part of VE. The oligopeptides, minerals, vitamins and inulin are added based on the pure goat milk, so the prepared goat milk powder has more comprehensive nutrition, and is more in line with the digestion and absorption characteristics of middle-aged and aged people; the nutrients can be absorbed and used efficiently; the nutritional value is higher than that of ordinary goat milk powder, and the biological utilization rate of the nutrient substances in the goat milk powder formula is increased. The goat milk powder helps the middle-aged and aged people enhance the body immune functions, resists hypertension, hyperlipidemia and hyperglycemia and prevents senile chronic diseases.
