1, salt coagulation If it is fresh pig blood, you can put a little bit of fine salt in the pig blood, and then let the pig blood settle for about 30 minutes, so the solidified pig blood is more conducive to preservation. Coagulated pig blood can be stored in cold water or light salt water, preferably uncooked water, so that it can be stored for up to one day.

2. Refrigeration If you want to keep pig blood for a longer time, you can put it in a fresh-keeping box, soak it in some cold water and put it in the refrigerator for refrigeration. Generally, it can be kept for about 3-5 days. It is recommended to change the water once a day. It should be noted that pig blood should not be stored in the refrigerator, and the taste and color of frozen pig blood will be much worse.
