Solid concentrated cow milk and preparation method thereof

The invention provides a solid concentrated cow milk and a preparation method thereof, and belongs to the technical field of dairy product processing. The preparation method includes the following steps: freezing concentrated cow milk to a center temperature of -15 DEG C to -20 DEG C to obtain the solid concentrated milk, wherein the solid content of the concentrated cow milk is 14%-18%, the freezing manner includes plate freezing at the condition of -28 DEG C to -32 DEG C, and the volume of the solid concentrated milk is 800-1200 cm . During the storage of the cow milk, due to the action ofmicroorganisms and lipase and protease in the milk, the stability of the cow milk can be reduced, the freezing of the concentrated cow milk provided by the invention can inhibit the reproduction of the microorganisms in the cow milk and reduce the activity of the lipase and the protease, so that the stability of the cow milk can be maintained, the shelf life of the concentrated cow milk can be prolonged, and the solid conc
