PROBLEM TO BE SOLVED: To provide a method for concentrating cow milk, and a method for preparing dairy products.SOLUTION: A method for concentrating cow milk includes collecting cow milk and passing through reverse osmosis membrane concentration at 0-7°C so as to obtain concentrated cow milk. The mass content of lipid in the concentrated cow milk is 0.2-10%, and the concentration temperature is 4-6°C, or the mass content of lipid is 4-9% and the mass content of a soluble solid is 12-32%. The mass content of protein in the concentrated cow milk is 3.3%. A method for preparing dairy products includes obtaining the dairy products by passing the concentrated cow milk which is obtained by adopting the concentration method, through a formulation step, a sterilization step, and a packaging step. The cow milk has only an almost physical change in a processing step through low-temperature concentration at 0-7°C, and the natural state of the cow milk is retained to maximum.SELECTED DRAWING: Figure 1 |
