When buying pork, press it by hand. Normal fresh pork will have good elasticity and will return to its original state immediately after being crushed. If you click it, you will feel that the meat is soft and inelastic, indicating that the pork is not fresh. Fresh pork smells normal and tasteless, if it is toxic, sour or rancid. Then it's probably dead pork, or pork that has been rotting for a long time.
Matters needing attention in pork storage
If you want to keep the pork for longer, you can cook it with soy sauce. Boil the soy sauce, pour the boiled soy sauce into the pork, cover it and keep it for about half a month.
It is also a good method to suggest users to air-dry pork. Air-dried pork has less water, is not easy to produce bacteria, and will be stored for a longer time. You can cut the pork into strips, then tie it with rope and put it in a bigger container to dry. When drying, it needs to be placed in a cool and ventilated place, not in a humid place, so pork is prone to long hair.
