1. Freezing preservation: clean the bacon, drain the water, wrap it with plastic wrap and freeze it in the freezer of the refrigerator. This preservation method is suitable for all bacon, and it lasts for the longest time. Even if you keep it for three to five years, it will be no problem. If you seal it again, the effect will be better. You can also store bacon in the freezer, which will last for at least a year without spoilage.

2. Hanging for storage. If your local room temperature is lower than 2 degrees Celsius and the humidity in the indoor air is lower than 6%, you can hang the bacon indoors in a cool and ventilated place without sunlight, so it can be stored for about 3 months. The lower the room temperature and humidity, the longer it will last. This method of preserving bacon has a disadvantage, that is, it is easy to ooze oil for a long time, which will make bacon turn into firewood and affect the taste, so it is only suitable for short-term preservation of bacon when it is cold.

3. Buried preservation: after the bacon is cleaned and drained, it is wrapped tightly with food-grade plastic film, preferably with several more layers of plastic film, and then wrapped with a thick layer of sticky yellow mud, and finally buried in the ground for preservation. This preservation method can last for three years, and it will taste more delicious after being taken out. In fact, this method of preserving bacon is very popular in Yunnan, and the locals call it fragrant meat.

4. Seal the jar for preservation, chop the cleaned and drained bacon into small pieces, and then put it into a ceramic jar. Then put the cooking oil into the jar after it is cooked and cooled, and the amount of oil should be enough to immerse the bacon. Finally, just seal the jar mouth. This method of preserving bacon can last for one year.
