When buying Chinese cabbage, not all varieties of Chinese cabbage are suitable for long-term preservation. If you want Chinese cabbage to be preserved for a long time, you must choose Chinese cabbage with green leaves to buy. If the leaves of the cabbage you meet are yellow, then such cabbage is not suitable for long-term preservation.
2. Remove rotten leaves, yellow leaves and smear white wine on the roots.
After buying the cabbage, we have to pick it first, and pick all the rotten leaves and yellow leaves on the surface of the cabbage. Because these parts belong to the place where the cabbage has deteriorated, if they continue to be preserved, the cabbage will be infected and the whole cabbage will deteriorate. Secondly, we should remember to smear the roots of Chinese cabbage with white wine, because the roots of Chinese cabbage are the most susceptible places. After a simple smear with white wine, it can be well sterilized, so as to avoid infection of the roots of Chinese cabbage.
3, the temperature control
When preserving Chinese cabbage, it is also very important to control the temperature. Whether the temperature is too high or too low, Chinese cabbage will go bad during the preservation process. Therefore, when preserving Chinese cabbage, we must create a constant temperature environment and control the temperature at 3~8 degrees.
4, bask in the sun
We'd better dry the cabbage before it is preserved. When drying Chinese cabbage, instead of directly drying it in the sun, put it in a ventilated place and blow it for a few days to dry the moisture on the surface of Chinese cabbage. Because Chinese cabbage will be squeezed in the process of preservation, if its surface is not kept dry, Chinese cabbage will rot due to long-term squeezing. Therefore, when preserving Chinese cabbage, we must ensure that its outer layer is dry, and don't let it always be moist.
5, wrapped in plastic wrap
It is best to cover the surface of cabbage with a layer of plastic wrap, so as to prevent the loss of water during the preservation of cabbage. Cabbage wrapped with plastic wrap can be stored at room temperature, and we can also put it in the refrigerator for cold storage. However, when Chinese cabbage is being preserved, we must check it at any time. Once it is found to be spoiled, we must eat it as soon as possible.
