Can I still eat lotus cabbage leaves when they turn yellow?

Vegetables are one of the most common foods we eat in our daily life, and now when we go to the market to buy vegetables, we will find that there are a variety of vegetables for us to choose from. But in winter, Chinese cabbage is still the favorite vegetable of every household, and many people will buy some cabbage to store at home in winter, so can Chinese cabbage leaves be yellowed and eaten? How do we store the Chinese cabbage we bought?

Can you still eat Chinese cabbage leaves when they are yellowed? How do you store Chinese cabbage?

1. Can you eat Chinese cabbage leaves when they are yellowed?

In winter, Chinese cabbage can be said to be a must-have vegetable for every household, and the nutritional value of Chinese cabbage is very high, so people will buy more in winter and put it back, but it is easy to have yellowing of the leaves after a long time, so can you still eat it if this situation occurs? In fact, if the leaves of Chinese cabbage do not turn yellow very much, then you can still eat it, and the yellow leaves are because of the chlorophyll in Chinese cabbage.

It is lost and eventually becomes lutein.

As a result, the leaves have turned yellow, so you can still eat it, but the taste of the cabbage is not as good as at the beginning, so if you find that the cabbage has turned yellow, you can still continue to eat.

Chinese cabbage leaves are yellowed.

Second, how to preserve Chinese cabbage.

If we buy back more cabbage, we still have to pay attention to the preservation method, we can buy back the cabbage to a dry and ventilated place for preservation, do not put the cabbage in a relatively high temperature and not ventilated place, and pay attention to the cabbage to pour it after a few days to prevent long-term placement of rot, and we = in the process of turning the cabbage, if there is yellowing or rotting, to take it out in time, so as to prevent the rotten pollution of other good cabbage.

1.Turning yellow proves that it has gone bad, like cabbage, and other large leafy vegetables, when the leaves are broken, they will also produce harmful substances such as nitrite, and eating too much will hurt the body.

2.It is recommended that when storing vegetable leaves, they can be placed in a cold place for a short time, or soaked in water, which is not easy to turn yellow.

3.Many people think that nitrite can only be found in leftovers and pickled vegetables, but food experts point out that fresh leafy greens in summer can also produce disease-causing nitrite if left for a long time.

Although it's the season when fresh greens are on the market in abundance, there are still busy people who like to buy large quantities of leafy greens at once and store them in the refrigerator. Experts point out that green leafy vegetables are prone to oxidation, even in the refrigerator for a long time, the original fresh leaves turn yellow, wilt and even begin to rot, and nitrite is easy to be produced. Not only are these vegetables inedible, but they can also contaminate other foods in the refrigerator.

After eating nitrite-containing food, people feel dizzy, headache, fatigue, chest tightness, nausea, vomiting, cyanosis of the lips, ears, nails and **; In severe cases, cyanosis will occur in the conjunctiva, face and whole body, and the patient's heart rate is rapid, irritability, dyspnea, and even coma, convulsions, incontinence, respiratory failure and other symptoms.

Abstract There are five cases of yellowing of lotus leaves. First, the light is insufficient, so you should bask in the sun too much. Second, the fertilizer is insufficient, and some nutrients are missing, so nitrogen and phosphorus fertilizers need to be supplemented.

Third, the soil or water quality is alkaline, and some ferrous sulfate can be added. The fourth is frost damage, which should be moved to a place with a suitable temperature. Fifthly, if you are affected by the disease, you can use carbendazim.

What to do if the leaves of the lotus flower are yellow1, bask in the sun more (1) Specific reasons: The lotus likes the sun, and if the light is insufficient, it cannot fully photosynthesize, and the leaves may turn yellow. (2) Solution:

Get plenty of sun. Plants raised at home can be placed in a sunny place, not too shady. 2. Supplementary fertilizer (1) Specific reasons:

It is mostly manifested in the color of the young leaves that have just grown yellow, and the old leaves will be relatively normal. This phenomenon is more common during the growth period. Most of the types of fertilizers that are lacking are nitrogen and phosphate fertilizers.

2) Solution: Supplement nitrogen and phosphorus fertilizers in an appropriate amount, the concentration should not be too high, and the amount should not be too large. Lotus 3, add some ferrous sulfate (1) specific reasons:

If it is a water-fed plant, the water quality may be alkaline; If it is a soil-raised plant, it may be alkaline soil. Either way, it affects the plant's ability to absorb trace elements, causing the leaves to turn yellow. (2) Solution:

You can change to soil and water, or you can add some ferrous sulfate. 4. Put it in a warm place (1) Specific reasons: the plant is not very cold-tolerant, the temperature drops sharply, and the leaves are easy to turn yellow after being damaged by frost, or the temperature difference is too large.

2) Solution: Keep in a warm place. In addition, we must also pay attention to regulating the temperature difference, not too large.

Lotus 5, prevention and control of diseases (1) specific reasons: more threatened by fungal diseases, large macula will appear. Workaround:

Carbendazim can be sprayed, but not too much, otherwise it will be counterproductive.

It's okay to eat, but it doesn't taste good. Yellowing of cabbage indicates a loss of chlorophyll and conversion to lutein. The cabbage begins to react with dehydration, and the vegetables begin to grow old, and the taste is not good, but it is not toxic and can be eaten.

The reasons for the yellowing of cabbage leaves may be:

One is yellow, that is, too much water causes the soil to accumulate water for a long time, poor air permeability and even some fibrous roots rot. It shows that the young leaves are dark yellow and dull, and the new shoots are shriveled.

The second is fat yellow, that is, fat, which is manifested as the tip of the old leaves turning yellow and falling off, and the new leaves are thick and shiny, but generally uneven and unstretched. You can sprinkle a layer of radish seeds and pull them out after a few days of emergence to consume nutrients.

The third is dry yellow, due to long-term lack of watering or dehydration, although the new leaves are normal in color, the lower leaves gradually dry up and fall off and age.

It won't be poisoned, it's just not delicious.

1. Too much water in the field, poor soil permeability and drainage, resulting in rot of cabbage roots, at this time the cabbage leaves will lose their luster, fade green, and gradually shrink.

2. Excessive fertilization will cause fertilizer damage, resulting in fat yellow cabbage leaves.

3. There is a lack of water in the field, and there is no timely replenishment of water, and the cabbage is dehydrated, and the leaves gradually age and turn yellow. The fourth is that due to the lack of fertilizer, the effects are not good, resulting in no vitality of the leaves, but the color is not really yellow, which can be described as thin yellow muscles.

4. Because the soil is alkaline or the water quality is alkaline, it has an impact on the growth of cabbage. The last thing we should pay attention to is that the cabbage leaves are yellow, and it may also be caused by pests and diseases.

Cabbage leaves yellow, can really eat, 60 years of yellow cabbage leaves, people are also eaten as vegetables, now people's living conditions are good, just eat the white heart yellow inside do not eat, in fact, yellow can also eat.

The cabbage leaves are yellow and cannot be eaten.

Because yellowed cabbage also has nitrite, nitrite can cause cancer.

In fact, the yellowing of the leaves is due to the loss of chlorophyll in the cabbage and finally turns into lutein, resulting in the yellowing of the leaves. In this case, the yellowed cabbage is edible, but the taste of the yellowed cabbage is not as good as before, and the nutritional value is not as good as when it was freshest at the beginning. We can remove the yellowed cabbage leaves and cook again.

The nutritional value of cabbage is very high, if the cabbage leaves turn yellow, it proves that the cabbage has some quality changes, so the cabbage leaves will produce nitrite harmful substances when they are bad, and eating it will have an impact on health, so we generally have to go out of the yellow leaves when eating cabbage before we can eat it. Usually, vegetables should not be stored for a long time, so be sure to pay attention to the time of freshness.

It is best not to eat cabbage leaves when they are yellow, because they have gone bad and will hurt your stomach.

The cabbage has yellow leaves, and it is better not to eat the yellow leaves. Yellow leaves are thrown away.

Don't, the good leaves are green, and the yellowing is bad, and the stomach is diarrhea.

If the white shirt is yellow, it cannot be eaten, and there are toxins in it, which cause harm to human health.
