What are the storage methods of vegetables?

1, vacuum preservation method: vegetables and fruits have been picked, transported and bought home for a long time. Coupled with the high temperature weather, even if it is put into the refrigerator, the vegetables will be dehydrated and dried up within two days. In fact, in order to keep vegetables fresh, in addition to the appropriate refrigeration temperature, the most important thing is to isolate the air. First put a handful of vegetables into the fresh-keeping bag, don't fill it too full, and leave a 1/3 position at the mouth of the bag! Then prepare a basin of water and sink the fresh-keeping bag with vegetables into the water. Remember to leave the bag mouth outside, and don't let the water drown the bag mouth. Then, with the help of water pressure, the air in the bag is squeezed out, the vegetables are pressed, gently rotated, and the air in the bag is completely emptied, and then the bag mouth is tied tightly. In this way, vegetables can be stored in the refrigerator for more than three days, and the leaves are still tender green when they are taken out.

2, water absorption and preservation method: bought flowers can be inserted in vases and kept in water for many days. In fact, vegetables can also be kept fresh in this way. This method is suitable for root vegetables such as asparagus, spinach, celery and Chinese cabbage. Just tie these vegetables into a bundle, put them in a bottle, and pour some water so that the roots of the vegetables can absorb water. Vegetables so preserved can be stored for 1-2 weeks even if they are not put in the refrigerator, as long as the temperature is appropriate. Of course, the temperature is high in summer In order to keep vegetables fresh, you can put them in a small water bottle and put them in the refrigerator. Vegetables can be eaten for a long time once.
