Recently, it's over 30 degrees below zero in Inner Mongolia. How are local fresh vegetables preserved?

When it comes to the preservation of vegetables in cold regions, I remember grandma always dug a cellar in the yard when she was a child, and vegetables and fruits were hidden in the cellar for preservation. Some people even cover vegetables with warm quilts or straw curtains to prevent them from freezing. This is the most common way to store vegetables in winter in Inner Mongolia. Now every family has a refrigerator, which can also keep the dishes fresh. Let me introduce some fresh-keeping methods of vegetables in Inner Mongolia.

First, it is best not to wash fresh vegetables, and wrap them roughly with paper, which can effectively prevent water evaporation, or make a few small holes in clean food plastic bags and put fresh vegetables into plastic bags to ensure ventilation and effectively prevent bacterial growth. Adjust the refrigerator temperature to 3-6? C, this is the most suitable fresh-keeping temperature, which can keep fresh for about 1 week. The principle of storing vegetables in the cellar is the same.

Second, the preservation of green leafy vegetables is mainly to ensure that its leaves do not rot. Our method is to wrap the leaves in newspaper and toilet paper, and then sprinkle some water on the surface, so that the wrapped vegetables can be placed in the refrigerator or cellar with the roots down to ensure that the leaves do not rot.

Three, leeks, shepherd's purse and other fine-leaved vegetables, wrapped in fresh Chinese cabbage leaves and placed in the cellar, can also extend the fresh time of leeks.

4. Lettuce will become soft and discolored after a long time. We usually pick the heart of this cabbage, put it in a wet tissue to make it fully absorb water, and then take out the paper ball after the vegetables fully absorb water, and then put the vegetables in a plastic bag to keep them soft for a long time.

Five, garlic, onion, ginger, pepper, these side dishes, all in the net bag. Hang it in a cellar or a dark and ventilated place at home, or put it in a jar with air holes. Most of the old ginger is buried in the sand and preserved, and now it is taken out of the sand when eating. Fresh ginger can be wrapped and stored in the cellar or refrigerator.

In a word, in such a cold area as Inner Mongolia, fresh vegetables must be wrapped well to prevent vegetables from losing water and passive heat preservation. Store underground or in a constant temperature refrigerator.
