1, fresh sheep blood can not be directly frozen treatment.

2, because sheep's blood contains a lot of water, put in the refrigerator to freeze the water inside. This is equivalent to the separation of the water in the blood, and when the water melts, the blood will become powdery without the water as a binder.

3, but don't worry, as long as you add the right amount of water and salt, stirring vigorously with your hands until a large number of bubbles, and then fish out the foam and let it stand, to be solidified into a pot of cool water and slowly heat to make it cooked.

4, sheep's blood is generally not advocated for long-term preservation. First of all, to do the culture medium of sheep blood should not add other things, such as preservation of liquid and so on, without special treatment of sheep blood would not be preserved for a long time, their own hemolysis is also inevitable. Secondly, blood cells themselves have a metabolic process, and will consume nutrients in the process of long-term preservation. Again, some of the components of the blood itself is not stable, long-term preservation will decompose and consume.
