Pork is frozen in the refrigerator. If it is not sealed and frozen in a bag, it will be tasteless for two or three months. If you put pork in a food bag, fill it with water and then freeze it, it will taste like pork for half a year. Because when pork is frozen, it will also reproduce bacteria, but it will reproduce slowly. If there is no food bag outside, the appearance of pork will change color for a long time and the meat will have no taste. But on the whole, it can still be eaten for a year.
