Some people put the pork they bought directly into the refrigerator. The temperature in the refrigerator is usually 0-5 degrees Celsius, so keeping fresh pork for 3 days is no problem, but after 3 days it will spoil. Some pathogens that are active on the surface of the pork will begin to multiply in large numbers, decomposing the protein and fat of the pork, causing the pork to smell bad and become stale and inedible. Therefore, if you cannot finish the piece of meat you just bought within 3 days, you need to store it in the freezer!
Putting meat in the freezer also has a shelf life. In general, fresh pork can be stored in the freezer for up to 6 months. You should not eat it after this time. Because the meat is frozen for too long, the bad smell in the refrigerator will penetrate the meat, making the meat tasteless, and the protein and fat in the meat will denature if frozen for too long. The nutritional value of pork stored for a long time is also relatively low. Every time you store pork, you must remember the expiration date. There are also tricks to preserve pork in the freezer, you not only need to put pork directly in the freezer but also need to know how to preserve pork properly so that the flavor does not change after 6 months.
