Sheep placenta extract freeze-dried powder and preparation method thereof

The invention provides sheep placenta extract freeze-dried powder and a preparation method thereof, and belongs to the technical field of freeze-dried powder preparation. The freeze-dried powder comprises an A-phase component and a B-phase component, wherein the A-phase component comprises oat beta-glucan, cordyceps militaris extract and sodium hyaluronate; and the B-phase component comprises oligopeptide-1, oligopeptide-3, hydrolyzed sheep placenta extract and serum albumin. In a preparation process, by strictly controlling the temperature and time of each step and various components, especially the oligopeptide-1, the oligopeptide-3, the hydrolyzed placenta (sheep) extract and other components, and by controlling the content and proportions of the components, the wall hanging phenomenonof the freeze-dried powder in the preparation process is reduced to be within 2%, the production loss of a product is greatly reduced, the quality of the freeze-dried powder is improved, and the prepared freeze-dried powder o
