What are the little black dots on Chinese cabbage and can you eat them?

Winter is the season to eat cabbage. This year's cabbage ** is also not cheap, but compared to his vegetables, it is acceptable. Cabbage is cheap, but the nutritional value of cabbage is not low at all.

Because cabbage is rich in vitamins, dietary fiber and protein, there is a folk saying that it is better to eat cabbage than cabbage. When buying cabbage, there are sometimes small black spots on the leaves of cabbage, and many people don't know why there are small black spots on cabbage, and whether this kind of cabbage can be eaten?

The small black spots on the cabbage are called cabbage black spot or cabbage sesame spot and are usually located on the inside of the petiole of the cabbage, mainly on the epidermal cells, and are about 1 2 mm in size. In this case, it is essentially caused by the distortion of the cell wall of the diseased cabbage petiole cells, which accumulates a large amount of black substance. It is likely that the excessive use of nitrogen fertilizer in the process of cabbage cultivation will destroy the cell membrane structure, and the higher the nitrogen concentration, the more serious the black spot disease.

It may be an aphid infestation. Cabbage can be harmed by aphids during its growth. Aphids eating cabbage leaves leave aphid secretions.

As the cabbage grows little by little, it forms dense black spots. Cabbage is not properly transported and stored during transportation, and cabbage that is not otherwise sick may have black spots.

Judging from the number of small black spots, if the number is not particularly large and there is no decay and deterioration, you can dig out the small black dots and eat them. Small black dots are physiological diseases, which generally have no bad effects on the human body, but will only cause cell membrane rupture, not caused by foreign pathological harmful factors, so a small part can continue to eat, but if there is a large area, it is not recommended to eat. Please note that the situation of black spots is more severe.

The broken part becomes an invasion point for bacteria, causing the phenomenon of rotting and deterioration, so it is best not to eat it.

To sum up, if there are few small black spots on the cabbage, you can dig out the small black spots and eat them later, if the small black spots are more serious, it is best not to eat them.

The small black dots on the Chinese cabbage are actually caused by the distortion of the plant cells of the stem cells of the Chinese cabbage leaves of some patients, and the accumulation of many gray-black chemicals in the distorted deformation. The degree of small black spots is light and does not harm the take, and the Chinese cabbage with more serious small black spots is not recommended to take.

The small black spots on the Chinese cabbage are because the cabbage is sick and there is a problem, if it is only a small black spot, you can eat it, if the black spot is particularly large and has rotted, you can not continue to eat it.

I think the little black dots on the bok choy are mold, so I don't think I can eat it.

If the cabbage is attacked by aphids, it may leave a black powdery substance on the cabbage leaves, which is the secretion of the aphids, which is rinsed with water before consumption, and will not have adverse effects on the human body. Chinese cabbage, also known as "yellow sprouts" and "cabbage", belongs to the biennial herbaceous plant of the cruciferous family, which can be used as a vegetable cooking, pickling, cold dressing, and can also be used as feed. In order to prevent and control Chinese cabbage black spot disease, the first thing is to disinfect Chinese cabbage seeds.

First, put the Chinese cabbage seeds in the sun for 1-2 days, then soak the seeds in warm water at 55 for 20 minutes, and then transfer them to cold water to soak the seeds, promote germination, and after the seeds germinate, use carbendazim wettable powder for seed dressing.

If the black spots on the leaves are large, it is mildew due to improper storage, and it is recommended not to use it. Sometimes the black dots of cabbage will be in several layers of the leaves, so you need to pay more attention when picking them. For vegetable farmers, the hard-working planting of Chinese cabbage, the black spots greatly reduce the appearance of the cabbage, affecting the quality of the sale, for the friends who do the vegetables, in the face of the cabbage with black spots, it is a pity that the leaf veins have not been damaged, but the old leaves absorb water nutrients and other functions, resistance is not as good as before, when the Chinese cabbage leaves are affected by various external factors, the performance of the old leaves is also more obvious.

There are many reasons for this phenomenon, such as insufficient nutrients in the land, or the cabbage does not get enough water, and the influence of temperature and light can also cause many small black spots to grow on the cabbage. 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.

The number of small black dots is not large, and the petiole does not show changes such as light yellow and oozing except for the small black dot area, that is, there are no signs of decay, so you can consider eating, and at the same time dig out the small black dots before eating.

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.

Chinese cabbage is a common vegetable in our lives.

But after a long time of storage, there will be a lot of small black spots on the cabbage, how can a good Chinese cabbage suddenly grow a lot of small black spots? Is the cabbage sick?

The scientific name of this small black spot on Chinese cabbage is "Chinese cabbage small black spot disease" or "Chinese cabbage sesame spot disease".

The small black dots on the Chinese cabbage are actually caused by the distortion of the cell wall of some diseased Chinese cabbage petiole cells, and the accumulation of a lot of black matter in the distorted place.

One possible cause of the small black dots on Chinese cabbage is excessive nitrogen fertilizer, because excessive nitrogen fertilizer will directly lead to the destruction of cell membrane structure.

These black spots on the cabbage may also be related to the following factors:

First, the storage and transportation process.

Chinese cabbage small black spot disease can also be aggravated during storage, and even Chinese cabbage without symptoms at harvest can occur during storage and transportation.

Second, it is related to Chinese cabbage varieties.

There are differences among different genotypes of Chinese cabbage, which provides a basis for breeding resistant varieties.

Can Chinese cabbage with black spots still be edible?

The degree of small black spots is light and does not affect the edible, the number is not much, except for the small black spot area, there is no change in color and exudate in the petiole area, that is, there are no signs of corruption, you can consider eating, and at the same time dig out the small black spots before eating.

Small black spot disease is a physiological disease, which is not caused by foreign pathological harmful factors, and generally has no adverse effects on the human body.

However, it should be noted that when the small black dots are severe, the cell membrane ruptures, and these ruptures can become the invasion point of bacteria, resulting in rot and deterioration, so it is not recommended to eat them.

1. Black spots on cabbage can generally be eaten, but the specific needs to be analyzed according to the actual situation. In the process of growth, cabbage will be attacked by aphids, resulting in black spots, in this case, it is usually only necessary to use water to wash off the black spots, and it can be eaten normally, and generally does not affect health.

2. At the same time, in the process of cultivating cabbage, because of the intrinsic genetics of the variety, excessive fertilization or environmental conditions, etc., it may lead to more black spots on the leaves and roots of cabbage, and grow inside the fiber, which cannot be washed off.

3. However, if the black spots are relatively dense, and the edges are discolored, dehydrated, etc., this kind of cabbage is generally not recommended to eat, because it may have rotted inside, it is easy to breed a large number of bacteria, and it may induce gastrointestinal discomfort symptoms such as diarrhea, nausea and vomiting after eating, which is not conducive to physical health.
