Is there a light colored part of the mango cut that is different from the flesh?

When the mango is cut inside, there is a light-colored thing that is different from the flesh, which is its core, and there are kernels in the core, that is, the seeds of the mango. But in fact, most mango cores have no kernels in them! You can't be a seed.

1. After the mango is cut, the pulp is placed on the surface, which is easy to be polluted by microorganisms and contaminated with bacteria, and low temperature can inhibit the growth and reproduction of microorganisms and prolong the preservation time of mangoes, so the cut mangoes can be sealed with plastic wrap or a crisper box and placed in the refrigerator for refrigeration or freezing. 2. The pickling environment is not conducive to the growth of microorganisms, and honey also has a certain preservative function, so mango can be marinated with honey to make mango jam for storage. 3. After slicing the mango, put it in a dryer and dry it, which can reduce the moisture on the surface and inhibit the growth of microorganisms.

If you don't have a dryer at home, it is recommended to dry it naturally and use a mesh cover to cover the dirt.

It means that this mango has rotted, and the meat inside has begun to deteriorate, if you eat it, the taste will be weird, there is no sweet fragrance of mango, this kind of throw it away, you can't eat it.

This is because this mango is ripe, and some of it is not fully ripe, so there will be different colors.

It means that this mango is no longer fresh, and it should be the whole piece of light-colored parts, and the dark ones are overripe after a long time.

Summary. Kiss, find a way to choose mangoes for you: when buying mangoes, you can choose the fruit shape, delicate skin and dark color, smell a strong mango fragrance, gently press with your hands, you will also feel the elasticity, this kind of mango is not only relatively fresh but also ripe, it is not recommended to choose mangoes with many black spots on the surface.

What is the white lump in the mango when it is cut? What is the reason?

Hello dear, the mango is cut and there is a white floc inside, which is fiber and can be eaten. If there is a deterioration such as black or black lines in the mango, it is not edible, and there are black threads in the mango that indicate that it has been placed for too long, resulting in oxidation, and the rich cellulose in the mango is also destroyed. The blackening of mango indicates that it has begun to mildew, and it is not recommended to eat it.

Concealment. Kiss, find a way to choose mangoes for you: when buying mangoes, you can choose the fruit shape is full, the skin is delicate and the color is relatively dark, it smells a strong mango fragrance, gently press it with your hands, and you will feel the elasticity, this kind of mango limb fruit is not only fresh but also ripe, it is not recommended to choose a mango with many black spots on the surface.

What is the cause of this?

Kiss, is the white one soft or hard?

It's soft or flocculent, it doesn't matter if it's edible, but if it's hard, it's not fully cooked.

It's not bad.

It's not a kiss, as long as it's not moldy and spotty, it doesn't matter.

Can't eat. The dark color of the middle of the mango proves that the inside of the mango has deteriorated, breeding a large number of bacteria and aflatoxin, after ingestion into the body, these bacteria will destroy the stability of the intestinal flora, easy to cause abdominal pain, diarrhea and other phenomena, and aflatoxin is a carcinogen, ingested into the body is not conducive to health. <

The mango is dark in color and cannot be eaten. The dark color of the middle of the mango proves that the inside of the mango has deteriorated, breeding a large number of bacteria and aflatoxin, after ingestion into the body, these bacteria will destroy the stability of the intestinal flora, easy to cause abdominal pain, diarrhea and other phenomena, and aflatoxin is a carcinogen, ingested into the body is not conducive to health.

It is advisable to eat fresh mangoes. In this way, it can effectively absorb the fiber and vitamins in it, which can enhance the body's immunity and promote intestinal peristalsis.

How to cut mango:

1. Rinse the mango simply, put it upright on the sticky board, cut it off with a knife close to the mango core. On the other side too, the knife is pressed against the mango pit. When all the mangoes are cut, they are divided into three parts: two slices of mango pulp and one piece of mango pit.

2. Draw a few knives longitudinally on the mango pulp, and the knife should not be too heavy, and it is better to cut the flesh without breaking the skin. A few more horizontal cuts. Once everything is drawn, gently top the middle with your hand, and the mango opens like a flower.

3. If you eat mango raw, it's good to eat it directly. The mango is small and easy to eat, and it doesn't get juicy all over the place. If you want to take the pulp, just cut it off with a fruit knife directly along the gap between the mango flowers.

Mango is a widely loved fruit that is loved by consumers for its sweet taste and rich nutrition. However, have you ever noticed that sometimes when you buy a mango, you will find a small hole or hole in the flesh, but the skin is intact? This is because mangoes are attacked by a common pest called the mango fruit fly.

Hazards of the mango fruit fly.

The mango fruit fly is a small flying insect that mainly harms fruit trees such as mangoes, guavas, and persimmons, and attacks by making holes in the skin of the fruit and laying eggs in it. After the fruit's parasitic larvae hatch inside the fruit, they can cause severe damage to the fruit and leave small holes or holes in the mango's outer skin.

The damage of this pest is not only to destroy the fruit, but also to affect the quality and taste of the fruit, making the mango flesh lose its freshness and sweetness, and reduce the market value of the mango.

How to prevent the harm of the mango fruit fly.

In order to prevent the harm of the mango fruit fly, we can adopt the following measures:

First, remove fallen fruits in time. If the fruit on the fruit tree is not picked in time after ripening, it is easy to become a place for mango fruit fly to lay eggs, so it is necessary to clean up and deal with the rotten fruit in time.

Second, strengthen the sanitation and cleaning of the park. It is necessary to keep the orchard clean and hygienic, and clean up the remaining fruits and fallen leaves in time to reduce the reproduction and harm of pests.

Third, the use of prevention and control agents. The application of control agents during fruit ripening and before and after harvest can effectively control the damage of mango fruit flies. When using pesticides, it is necessary to pay attention to the fact that pesticides cannot be applied during the ripening period, so as not to cause potential safety hazards to the fruit and human health.

What is the impact of the harm of the mango fruit fly on humans.

In daily life, if the control of mango fruit fly is not carried out, the number of insect pests in the fruit will increase, the market value of mango will be reduced, and at the same time, it will pose a potential threat to the health of mango consumers.

Because the mango fruit fly is active on the fruit, which affects the quality and taste of the mango. If you eat mango parasitized by fruit flies, not only will the taste be greatly reduced, but it may also cause food poisoning and allergies.

Conclusion When buying mangoes, be sure to pay attention to whether there are small holes or holes on the surface of the fruit, which may be a sign that the mango fruit fly has placed eggs on it. In order to improve the quality and taste of mangoes, we also need to take the harm of mango fruit flies seriously, and take measures such as cleaning and prevention to avoid bringing such food to our tables.

Because at this time the mango undergoes a browning reaction. So it turns from yellow to black. The instructions for untying the pants are as follows:

1. Browning is a common discoloration phenomenon in food, especially when fresh fruit and vegetable raw materials are processed or stored or damaged by machinery, the original color of food becomes darker, and these changes belong to browning.

2. Enzymatic browning mostly occurs in fresh plant foods such as fruits and vegetables, which is the result of phenolases-catalyzed phenolic substances to form quinones and their polymers. Plant tissues contain phenolic substances, which are used as respiratory transport substances in intact cells, and under normal circumstances, the dynamic equilibrium is maintained between redox reactions (the interchange of phenol and quinone), and when the tissue is destroyed, oxygen invades in large quantities, breaking the balance of redox reactions, so the accumulation of oxidation products and further polymerization and oxidation of quinone occur to form black.

The blackening of the mango is caused by oxidation, and the blackening of the fruit is caused by the rupture of the skin of the cut fruit and the membrane that acts as a "protective wall" inside, allowing oxygen to enter the inner part of the fruit. Oxygen reacts with (usually embedded in) some compounds in the fruit, oxidizing them. And there are many compounds that are brownish-black after being oxidized, so that the cross-section of the fruit is also blackened.

Mango weevil larvae eat the flesh of the fruit and leave behind faeces and black powder.

Introduction] The mango weevil is a coleoptera in the family Weevilidae. The larvae eat the pulp, the moths are criss-crossed, and the mango is full of insect feces and black powder, which is inedible.

Morphological characteristics] Adult body is 6 mm long, 3 mm wide, oblong, black-brown. The head is short, the compound eyes are dark black and shiny, and the beak is millimeter long, black-brown, and curved downward. The antennae are 11-segmented, the first segment is long, the third to seventh segment is rounded, and after the eighth segment is enlarged and spindle-shaped.

There are dark black notches on each side of the elytra forming 10 longitudinal grooves, and there is a macula in the anterior region of the breech, which is inverted in the shape of a figure-eight. The eggs are oblong and creamy white. The larvae have yellowish-brown heads, milky white carcasses, thorax and feet degenerate into small protrusions, no toes, only a bristle-like substance, a total of 5 instars.

The pupae are milky white, later beige, with 1 pair of tail spines at the end of the abdomen.

Life habits] occurs in Yunnan in 1 year and 1 generation. Adults overwinter in lichens, forks, cracks, etc. in tree trunks. In March of the following year, the overwintering adults are active and enter the copulating oviposition period, and in the first half of April, they lay eggs under the young mango peel, with 2-3 eggs and an egg period of 4-6 days.

The larvae feed on the pulp after hatching. When the fruit is ripe, the larvae have completed the pupal stage and crawled out of the emergent holes, first live on the fruit branches, and then gradually sneak into the overwintering site for overwintering.

Prevention and control methods] 1. Quarantine fruits, seeds, seedlings and vegetative propagation materials.

2. Clean the countryside, pick up the fallen fruits and leaves on the ground in time, and deal with them in a centralized manner.

3. Remove the weeds under the forest and plough the land, and destroy the pupal chamber of the weevil.

4. Within one to one and a half months after flowering, or when the tender shoots grow to 5 cm, spray pyrethroids, trichlorfon or dimethoate.

In the process of growing, mangoes are pested
