How to keep vegetables in cold storage for a long time?

1, dry the surface moisture: the moisture content of green leafy vegetables is relatively high, and many times vegetables sold in the market will be sprayed with water in order to sell well. If you put wet vegetables in the refrigerator, it will increase the overall humidity of the refrigerator. Low temperature and high humidity are more likely to breed bacteria and cause spoilage of ingredients. Therefore, if you want to prolong its storage time, it is best to spin, dry and dry the vegetables before putting them in the refrigerator.

2, clever use of absorbent paper/paper towels: the surface moisture should not be too much, and the moisture of the vegetables themselves needs to be locked. Using fresh-keeping bagged vegetables can not only isolate odor, but also slow down water evaporation and prevent air drying. We can also put two pieces of absorbent paper in the fresh-keeping bag. If you don't have absorbent paper, you can also use a paper towel with good absorbent effect, which can keep the vegetables in the refrigerator longer. The main component of absorbent paper is cellulose. The cellulose in the paper is interlaced into a network with many gaps and can contain water.

3, don't be busy washing vegetables: Some people are used to washing vegetables before putting them in the refrigerator, but this operation will actually make vegetables rot faster! Because there is a layer of wax on the surface of fruits and vegetables, you will see it when washing vegetables. Because of the wax, water droplets condense on the surface of vegetables. This layer of wax can protect them from microorganisms. The wax layer will be destroyed after cleaning, but it is easy to deteriorate and rot.

4. Avoid the low temperature area: Generally speaking, the temperature inside the refrigerator is lower than that outside. Vegetables and fruits are relatively afraid of freezing. If it is stored in an environment with low temperature for a long time, it is easy to be "frostbitten" and the surface will become yellowish brown, withered and soft. Therefore, it is best not to store fruits and vegetables on the inner wall. Bean products and leftovers are not afraid of freezing, so they can be put inside.
