There are many kinds of food for hoarding, such as rice, flour and beans, which are indispensable main foods in daily life, and also the main sources of nutrients such as carbohydrates and protein, which are relatively storable, with a shelf life of more than one year and a longer edible period. These are essential materials.

Many delicacies are related to "hoarding grain", such as pickled vegetables, bacon and sausage in winter, which are all invented by people for convenient storage, especially preserved bacon, which can be preserved for more than one year as long as it is properly preserved, and its taste is not much worse than that of fresh meat. When you go to the supermarket to "stock up", you can buy more preserved sausages and bacon to be prepared.

Foods such as flour, rice and oil are easy to store, while meat can be stuffed into the refrigerator for freezing. However, only vegetables, especially green leafy vegetables, will turn yellow, wither or even rot after two or three days of storage. However, people need some vegetables to supplement vitamins and minerals, and store some dried vegetables, such as dried fungus, dried mushrooms, dried beans and other ingredients, which are in a sealed or dry environment and hardly deteriorate and can be preserved for several years. In addition, fresh vegetables such as Chinese cabbage, radish, potatoes and onions that can be stored can also be purchased.

in special period, it is the key to strengthen nutrition and health. We should always keep some dairy products at home, but the shelf life of both fresh milk and yogurt is not long, so milk powder is a good choice. Fresh milk is used as raw material, and it is dehydrated after processing, showing a powder state, which can be stored for several years in dry environment, and its nutrition is almost the same as fresh milk.
