How to keep vegetables fresh in the offshore area?

If the temperature is low and the weather is cold, tie the fresh vegetables tightly with a convenient bag or wrap them with plastic wrap, and don't let air in. If you don't let air in, vegetables will turn yellow and rot easily. This is my personal opinion. If you have different opinions, put the fresh-keeping bag in the refrigerator to keep it fresh, and remember that the most important thing is not to touch the air with the fresh-keeping bag. If it enters the air, it will oxidize and the color will get old. It's that simple.

Squeeze out the air inside and seal it. Prepare a new pot, fill it with half water, put the vegetables in the pot, and don't soak it. Finally, squeeze out the air by hand, seal it quickly, and put the vegetables in the refrigerator after it is completely sealed. However, people with life experience should have found a phenomenon. Even if the vegetables bought are kept in the refrigerator for 3 days, they are not fresh, even wrinkled and the leaves are rotten. While other vegetables are still lying in the refrigerator intact.

Plastic bag preservation method. You can put vegetables in plastic bags, tie the bags tightly and put them in a cool and dry place. In this way, vegetables can be kept fresh for 10- 15 days. There is usually a lot of water on the vegetables you just bought. Let the vegetables dry in a dry place for half an hour, so that the water drops on the surface of the leaves are dry thoroughly. Put it directly in a fresh-keeping bag without washing, or prepare a paper box with potatoes in it when the temperature on the balcony is low. Wash and dry before storage, and later find that it will last longer without washing or in the refrigerator. Potatoes must not be dried; They germinate when heated.

The picked plants are still alive for a period of time, and the respiration continues. If the package is tight, it is difficult for the evaporated water to decompose things easily. In addition, don't put it with ripe fruit. As we all know, ethylene is the best ripening agent, but don't leave it too dry; If you buy food in the supermarket, the food itself will be very dry, so you must order some water for it. Don't order too much water, it will go bad easily.
