Soaking in white wine is a method to keep fried peanuts crisp, which is used by many families. The specific method is: when the fried peanuts are just out of the pot, put them in the plate, add high-concentration white wine while it is hot, and mix well quickly. The amount of high-concentration liquor should not be too large, just enough to mix all peanuts; When the peanuts have just cooled, sprinkle some salt and stir well. The fried peanuts soaked in this way can basically maintain a crisp taste if they are left for a few days at will. This method can't be used for people who don't like salted peanuts or wine.

The refrigerator is almost a necessary household appliance in urban and rural areas. So peanuts can be hidden in the freezer of the refrigerator, which can keep crisp for a long time. It should be noted that there is also water vapor in the freezer of the refrigerator, which should not be exposed for too long, otherwise peanuts will absorb water and regain moisture; After freezing, once it is thawed and absorbs water quickly, it should be taken out with the limit. If you eat too much at a time, you will get wet soon after eating. Once the refrigerator is cut off for a long time, the frost in the freezer will begin to melt and peanuts will regain their moisture quickly.

oil seal preservation of peanuts is a unique method. After the peanuts are cooled in the pot, immediately put them into a container for storing peanuts, then spread them out, pour them into vegetable oil such as sesame oil, olive oil or camellia oil until the oil level is just below the peanuts, and then cover the container. Peanuts stored in this way can remain crisp for a long time, and there is no problem when stored for two years. Even if the containers are open, they can remain crisp for ten and a half months. Moreover, the stored peanuts have a unique oil flavor, and the vegetable oil stored with fried peanuts will also have a unique flavor when used for frying in the future.

note: peanuts must be cooled before they can be stored with oil seal. Peanut oil is ok, try not to use peanut oil. The fresh-keeping effect of peanut oil is not as good as other vegetable oils.

It is also a common preservation method for many people to put fried peanuts into plastic bags and then tie the bag tightly. Everyone knows how to do it. It should be noted that food-grade plastic bags must be used instead of common black and red plastic rucksacks. This plastic bag contains substances harmful to human body, which can penetrate into peanuts through oil; In addition, peanuts should be cooled in a pot and bagged for preservation; When storing, it is best to press the bag mouth down.

some people like to put fried peanuts in jars or bottles. When choosing a bottle, it is best to use a glass bottle. If there is no glass bottle, use the empty bottle accumulated by buying oil at home. Try not to use simple beverage bottles or non-food grade bottles. Peanuts should be cooled before they can be put into bottles.

For cooked food stalls or restaurants, the above method is not feasible, because it needs to be put in an open container for customers to taste and sell. In order to prevent the moisture regain from being too fast, most peanuts can be covered with flat flannel or cotton towel, and only a small part is exposed for customers to choose. If the goods left over from the day are wet, fry them in the next oil pan for a while, and then they will be crisp.
