The invention relates to the technical field of food, in particular to high-
protein milk and a preparation method thereof.The preparation method comprises the steps that
raw milk is sequentially subjected to milk purification, fat
standardization, primary homogenization,
pasteurization, concentration, secondary homogenization,
protein maintenance, ultrahigh-temperature sterilization and sterile filling; the fat
standardization comprises the step of adjusting the ratio of fat to
protein in the
raw milk to 1.11: 1-1.17: 1; the concentration comprises the step of concentrating the
protein content of the pasteurized milk to 3.6 g / 100g or above. According to the invention, the proportion of fat and protein in the
raw milk is adjusted in the purified milk
separation process, so that the proportion is controlled within a specific range, and the problem of inconsistent product stability and taste of the high-protein milk can be effectively solved; by optimizing technological parameters such as primary homogenization, secondary homogenization and ultra-high-temperature sterilization, the use of food additives can be avoided, and meanwhile, the uniform taste of the product and the
stable system can be effectively ensured.
