Why do peaches come out black when boiled?

Rotten.

Peach skin contains pigment, although it is relatively stable, even if it is washed by salt water, it is difficult to exude, but boiled in boiling water, for a long time, the cell membrane of the peel in the peach skin will be destroyed, and it will fade red, and then the peach skin will turn yellow until there is no color, which is a normal phenomenon and will not have an impact on the consumption of peaches, and the peach skin water contains certain vitamins, minerals and trace elements, and moderate consumption has certain benefits for human health.

The value of peaches.

1. Peach has the effect of nourishing qi and blood, nourishing yin and nourishing Jin, and can be used for people who are deficient in qi and blood, yellow and thin face, palpitations and shortness of breath after a serious illness.

2. Peach kernels have the effect of activating blood and removing stasis, moistening the intestines and laxative, and can be used for amenorrhea, bruising and other auxiliary **.

3. Peach kernel extract has anticoagulant effect, and can inhibit the cough center and stop coughing, and at the same time can reduce blood pressure, which can be used as an auxiliary for hypertensive patients**.

4. Peach has high iron content, high potassium content and low sodium content, which is suitable for people with iron deficiency anemia and edema patients.

This is because peaches have pigment in them, and when they are heated, they will turn black, which is a normal situation, no need to make a fuss.

Why do you want to cook it, I usually use a pot to steam. Wash and cut the peaches and steam them in a basin. The peaches I cooked turned black, so I guess you used an iron pot.

This is a normal phenomenon, and it must have a chemical reaction in a high temperature environment, which will then cause its color to change.

Steamed peaches. It comes out black, and that's because the high oxidation temperature of peaches and water has a certain oxide, which will, turn black.

Because peaches have a higher sugar content, fructose changes when exposed to heat and reacts with oxygen in the air

After the peach is heated, there will be an oxidation reaction, so it will change color, which is also very normal.

Peaches come out black because of the pot you use and the action of oxygen in the air.

It means that the peaches have gone bad and should not be eaten.

The pulp of the peach is rich in protein, fat, sugar, calcium, phosphorus, iron, vitamin B, vitamin C and a lot of water, which can play a role in nourishing yin and nourishing the lungs for dry cough, hemoptysis, chronic fever, night sweats and other symptoms such as chronic bronchitis, bronchiectasis, pulmonary fibrosis, atelectasis, silicosis, tuberculosis, etc.

Peach has the effect of nourishing qi and blood, nourishing yin and nourishing Jin. It can be used for people who are seriously ill, have qi and blood deficiency, thin yellow muscles, palpitations and shortness of breath. Peaches have a high iron content and are an ideal supplementary food for patients with iron deficiency anemia.

Peaches contain more potassium and less sodium, which is suitable for edema patients. Peach kernels have the effect of activating blood and removing stasis, moistening the intestines and laxative, and can be used for amenorrhea, bruises, etc. Peach kernel extract has an anticoagulant effect and can suppress the cough center and suppress cough.

At the same time, it can lower blood pressure and can be used as an aid for hypertensive patients**.

Peach rot is a phenomenon that inevitably occurs in the ripening process of fruits. During the growth and development of the fruit, it does not always maintain a fully enclosed system. It is very normal for mold and larvae to enter the interior and invade.

1. Larvae. The larvae are mostly bored from the calyx and the stalk, and there are insect feces discharged from the cavities of the damaged fruits in the early stage, and there is no insect feces in the late stage. The larvae penetrate directly to the heart of the fruit, and the rot around the cavity often becomes black and gradually expands under the condition of high humidity, commonly known as black plaster, and the moth eats the peach, plum and apricot are mostly harmful to the pulp near the kernel.

2. Mold. Mycelium is latent in necrotic tissues or diseased dead fruits, or spores are hidden in the scales of buds for overwintering, and the following year it is spread by spores and infiltrated from the sepal tube to invade the heart of the fruit. The occurrence of disease is most closely related to the variety, and all fruits with open calyx mouths and long calyx tubes connected with the heart of the fruit are susceptible. The spoiled part of the fruit can easily smell musty or see mold.

In a humid and rainy environment, mold is more likely to grow.

Pay attention to it, be careful to eat diarrhea.

1. When the peaches are not yet ripe, the pest larvae burrow into the peaches and eat the pulp, which looks fine on the outside, but has deteriorated on the inside.

2. Peaches are infected by germs, and gradually begin to mold and rot from the inside out, such as mildew heart disease.

3. Peaches are rich in iron, which turns black when exposed to air, especially near the core, the iron content is very rich, if there is a crack in the stem, the flesh inside will contact the air and turn black.

4. Peaches are drenched in heavy rain before picking, and they are easy to rot from the inside out if they are stored for too long after picking.

5. During the development process, the poor development of peach seeds causes rotten hearts, resulting in the blackening of the kernel.

Peaches contain iron, due to oxidation in the air, resulting in peaches turning black, and the flesh part close to the peach pit is richer in iron, so it is easier to blacken, this oxidation phenomenon is obvious on apples, apples will oxidize and change color a few minutes after peeling, for such oxidation phenomenon, the impact on health is small, it can be eaten.

There is also a possibility that the effect of microorganisms is immediate, due to the invasion of microorganisms inside peaches, due to the metabolism of bacteria, their metabolites may turn peaches black, and the taste of such peaches has changed, and they are not edible, otherwise it is not good for health.

It is recommended not to eat peaches that are black inside. The flesh of some peaches is dark in color, but the flesh is dark and generally purple, and the flesh color will not be black no matter how dark it is.

There are a large number of bacteria and bacterial metabolites in the spoiled peaches, and the nutritional value of the peaches will be consumed under the action of microorganisms and their metabolites, so the spoiled peaches have no nutritional value, and because of the large number of bacteria, there may be toxins in the spoiled peaches, and eating such peaches is very harmful to the body, and may cause abdominal pain, diarrhea, and even gastrointestinal diseases.

Once a peach is found to have an abnormal taste, it should not be eaten immediately for any reason, because such peaches may have been affected by other factors, or have gone bad, and may not be good for health after eating.

The blackening of the peaches is likely to be caused by rotting and deterioration. Due to the reproduction of bacteria and microorganisms, the nutrients inside the peaches are consumed in large quantities, and the spoiled peaches also contain a large number of microorganisms and their metabolites, eating bad peaches does not have any nutritional benefits, and, due to the metabolism of microorganisms, there may be harm to the digestive system after eating, digestive problems and diseases, peaches do not continue to eat after they turn black, it is recommended to throw them away and no longer eat.

When you take it out of the freezer, the peaches are bad from the inside out.

Can't eat. Generally speaking, the flesh of peaches is slightly yellow, some varieties of peach flesh are red, if the flesh of peaches appears black, it is likely to be caused by deterioration, such peaches have been eroded by bacteria, loss of nutritional value, not only taste change, eating will also cause a certain impact on the body, so it is not recommended to eat peach flesh black.

When a piece of fruit rots at home, it is often eaten after digging up the bad piece and eating the leftovers. And doctors recommend that in ordinary life, try not to eat rotten and moldy vegetables and fruits. Even if only one piece of fruit is rotten, don't eat it whole, because the parts that are not bad may also be infected with bacteria, fungi, etc.

This is a normal phenomenon. Because the red color of peaches is anthocyanin, which is a natural pigment. It is characterized by its red color when acidic, and usually turns blue when it is alkaline, and there may be transitional colors such as purple and green in the middle. If the color is dark, it may appear purple-black.

This discoloration is normal. Peaches are pink because they contain anthocyanins, a natural pigment. Anthocyanins are red when acidic, usually blue when alkaline, and may have transitional colors such as purple and green in between. Can be consumed normally.

Washing peach hair with alkaline water is more scientific than washing with salt water. The peach skin is rich in pectin, which is easy to decompose under alkaline conditions, making the cell wall softer, making the peach skin easier to peel off and more convenient to eat. However, the time of soaking in alkaline water should not be too long, otherwise alkaline water entering the peach will destroy the VC, affect the taste of the pulp, and cause the fruit to change color and turn yellow or brown.
