It is best to store it with the outer leaves at the time of harvest, so that the possibility of small black spot disease is less. In addition, it is best stored at 4 degrees Celsius.

Farmers are thinking about choosing good nitrogen fertilizer to improve yield during the peak growth period of cabbage, but they don't know that this will lead to calcium deficiency and black spots in cabbage, but this kind of cabbage will not bring great damage to people's health when eaten.

Why are there small black spots on Chinese cabbage? Is it OK to eat? Tell you the answer once and for all.

After a long time, the surface is moth-eaten by insects, or because the storage environment is relatively humid, the formation of black spots. If it is not softened, it can be eaten without an off-flavor.

It may be caused by the excessive use of nitrogen fertilizer in the planting process, and the presence of aphids may also be present. Such cabbage is still edible, and there is no problem with eating it so far.

Small black spot disease is a physiological disease, which is the programmed cell death of Chinese cabbage cells themselves, which causes the rupture of the cell membrane, not caused by foreign pathological harmful factors, and generally has no adverse effects on the human body.

However, there is one caveat!

When the small black dots are severe, the cell membrane ruptures, and these ruptures can become the invasion point of bacteria, leading to decay and deterioration, so it is not recommended to eat them.

Whether the small black spots on the cabbage can be eaten depends on the situation, which may be congenital factors or mildew.

Some cabbage has small black spots, which are actually congenital factors, which need to be fertilized in the process of planting, and if excessive nitrogen fertilizer is used in the process of fertilization, it may cause damage to the tissue cell membrane of Chinese cabbage, resulting in small black spots. In addition, some cabbage has poor nutrient absorption, and is affected by the weather and soil. But if it's a congenital factor, don't worry.

If the cabbage has a lot of black spots, and the color around the black spots is yellow, and the juice is oozing out, it means that it is a moldy spot that grows after deterioration, which produces harmful substances, so in this case, you can't eat it, don't feel sorry for it if you throw it away, and you should be responsible for the body.
