If you keep them in the refrigerator at 0~4 degrees, they can be kept for about 3 days. If you store prunes in a refrigerator below 0 degrees, they will last longer, but the longer you store them, the less flavorful they will be. Therefore, it is best not to keep prunes for more than 3 days if they are kept in the refrigerator.
