Winter is a good time to eat Chinese cabbage, especially in northern Chinese cabbage, which is bought in bags. Chinese cabbage is nutritious and delicious. But I don’t know if you find black spots on it when you buy Chinese cabbage? What is the reason for this? Can such Chinese cabbage still be eaten?
In addition to the cabbage with small black spots on the market, this phenomenon may also occur in the cabbage without black spots in our daily storage. If you encounter such cabbage, don't throw it away or feed it to small animals. Small black spots like
are actually symptoms of Chinese cabbage. It has a scientific name called Chinese cabbage black spot disease, and another theory is Chinese cabbage sesame spot disease. The most common place is the Chinese cabbage stalk, and some are inside the cabbage cells, which is difficult to see through our naked eyes.
In addition, the black spots on the cabbage may also be related to the chemical fertilizer used. The nitrogen fertilizer in the fertilizer will easily damage the cabbage cells under excessive use, thus increasing the probability of the cabbage growing black spots.
For this kind of cabbage, you can observe the small black spots. If there are more small black spots, it is not recommended to eat the cabbage. It is not because Chinese cabbage black spot disease is bad for health, but because cabbage is prone to rot after this condition occurs, and there may be food safety problems when eating.
Cabbage with fewer black spots can be eaten without rot. For the storage of cabbage, in order to reduce the probability of black spots in cabbage, the storage temperature of cabbage is usually 4 degrees to 8 degrees, which can extend the shelf life of food.
Eat some cabbage in winter. Cabbage has a lot of water and is rich in vitamins and minerals. When eating, even cabbage leaves and cabbage petioles are eaten together, so as not to waste, the nutrients of both can be absorbed and utilized. It is beneficial to protect skin and gastrointestinal health in winter, prevent constipation, and supplement calcium.
