Can black spots on mango be eaten?

Mango is rich in nutrition, tender and sweet, and is known as the "tropical king". Right now is the season of mango fragrance. Recently, the topic of "what is the leopard mango" appeared on the hot search, causing heated discussion among netizens. Network videos show that some people are selling "leopard mango" at a price of 2 yuan per catty. The reporter noticed that there are a lot of black spots on the mango sold. In the video comment area, some netizens said that the so -called "leopard mango" is not fresh mango.

How about mango wearing "leopard print"? Do you still have some knowledge if you eat mango? May wish to listen to how experts in the field of tropical fruit research say.

Mango wears "leopard print"?

It's because "sick"

The golden peel is "embellished" with large and small black spots. At first glance, the leopard prints of the "wild domineering" are indeed a bit similar. Recently, a fruit shop in Nanning, Guangxi, sold 2 yuan a pound of "leopard mango", which really harvested a wave of traffic.

Mango wearing "leopard print" is actually because it is ill. In an interview with reporters, Wu Jingbo, a South Asian Tropical Academy of Tropical Agricultural Sciences, analyzed that there are many reasons for the occurrence of "leopard print". Important diseases of mango before and after mining. It is a "destruction home" that can endanger mango leaves, inflorescences, fruits and branches, causing a revenue before mining; it is also a "latent". Small brown spots appear on the peel, yellow halo around, and after several lesions are fused to form large spots, the "leopard mango" on the market appears.

However, mango anthracnose and human anthracnose are completely different. This kind of germs that only invade plants are not harmful to the safety of people's lives. For tropical fruits, "anthracnose" is common. For example, the cooked banana has a lot of dark brown spots on the epidermis, which is also related to the "lurking" anthrax bacteria on the peel.

Can the "Leopard Earline Mango" be eaten?

Expert reminder: The reason is unknown, eat carefully

In addition to the pathogenic disease of anthracnose bacteria can cause mango dark spots, some physiological diseases can also cause similar "symptoms". The most common is the cold damage or squeezed scars caused by low temperature storage. Mango is a jumping fruit, which is very cold -sensitivity. At the same time, mango peel contains polyphenol oxidase. After the above two cases are encountered, the cells in the peel will be damaged. The phenols in the cells will be released by oxidized into brown pyrine, forming small dark spots.

Therefore, "Leopard Earline Mango" is not a new variety, but a performance of mango quality level decreased or storage for a long time.

As for whether this mango can eat, Wu Jingbo believes that it should be treated differently. If it is only caused by physiological diseases, in most cases, the flesh has no deterioration, and it can be eaten with confidence after tearing off the epidermis. If the lesions caused by the germs, the black spots on the mango epidermis have the size of the nails, and the distribution is more, or the peel has cracks and the secretions exudate. It is recommended that you do not eat it anymore. Although the germ itself or the metabolites it produces does not necessarily endanger human life, it may pose a threat to human health.

Wu Jingbo reminds consumers that whether it is physiological or pathological mango diseases, the quality of mango is greatly reduced. Mistake -deteriorating mango can cause food poisoning, and symptoms such as diarrhea, abdominal pain, vomiting, and headache. Therefore, if consumers cannot distinguish the cause of the "leopard", they should eat it with caution.

How to choose

It's not enough to look at the beauty

Buying a mango, many people favor beautiful yellow appearance, and many people use the "gold standard" for judging the mature mango. So, is this common sense of reliability?

Researcher Wang Songbiao, a South Asian Tropica Institute of Tropical Agricultural Sciences, said that there are more than 2,000 mango varieties in the world, and the hereditary diversity is rich. The colors of peel are green, yellow -green, yellow -green covering red or bright red. Although most mango mature skin is golden yellow, there are also varieties that show yellow -red, yellow -green or green green. For example, Kate Mang, which is native to the United States, is mostly pale green, and the sun and the shoulders are light red; red ivory mang, the peel is light pink and green; Mang, the peel is green when it is picked, and some are green or green in the process of cooked.

Wang Song's bid further explained that the color changes of mango peel depends mainly on the degree of degradation and synthesis of chroma such as chlorophyll, flavonoids, and color of cosmetosin contained in the peel. Generally speaking, the mango is degraded during the mango cooked process, and the flavonoids and color of flavonoids are not degraded or even synthesized. Therefore, some green mangoes when they just pick up will turn yellow or yellow -red during the ripening process, and if the chlorophyll degradation is not sufficient in this process, it is green or yellow -green.

Unlike the peel, during the mango maturity, the containing material in the pulp is that starch is converted into sugar, acidic substances degraded, and aroma should be formed. Therefore, the method of observing the beauty is not reliable. To distinguish whether the mango is mature, Wang Songbiao suggests that it is best to judge by touching, smelling and other methods.

Touch: Gently push the mango shoulder with your hands. When touching, it feels that the flesh changes from hard to soft or elastic, and it is cooked after it is cooked and can be eaten. If it is still hard and unrelated, it means that the mango is not familiar after it is completely.

Wen: In addition to touching, you can also use the method of smelling to judge. The mature mango has a strong fruity aroma, especially the parts close to the fruit, the fragrance is stronger. Most of the time, consumers may buy unreasonable mangoes in the supermarket. What is going on?

Wang Songbiao explained that mango, like bananas, is a breathing leap fruit, which is not resistant to storage and transportation. If it is completely mature and softened in the orchard, some varieties will be fruitful, and some varieties will even cause rotten heart, causing losses, and completely mature picking. Mango cannot be transported long distances. Therefore, mango generally can pick it at seven or eight cities, and then concentrate on the transportation and salesplace to cooked or not cooked handling directly to the shelves. Consumers will be softened and eaten by themselves.

If the mango buying home is relatively hard and not familiar with, consumers can put it with apples, bananas, peaches, etc. into containers such as cardboard boxes and seal, and use the ethylene gas emitted by these fruits to ripen mango. Generally speaking, it can mature in about two or three days. The higher the temperature, the shorter the mango is softer. Putting directly in the room in summer can also become soft and mature.

How to eat

Mango is best cut into pieces

Mango not only has high face value and good taste, but also contains a variety of nutrients.

Wu Jingbo told reporters that mango is a food with high carotene, VC, selenium, and dietary fiber. It has health effects such as beauty, antioxidant, anti -cancer, and prevention of cardiovascular and cerebrovascular diseases. At the same time, mango contains ingredients such as mangolin, cichtinin, and has auxiliary treatment effects on cough, sputum, asthma, etc. Therefore, appropriate amounts and often eat mango are good for health.

When eating mango, many people are accustomed to bite food after peeling. However, Wu Jingbo does not recommend this kind of hearty eating method. Eating mango is best "elegant", such as cutting into small pieces to eat.

Wu Jingbo explained that mango contains a lot of substances that are likely to cause allergies, and the mango allergies are large, and those with severe allergies will cause redness and pain, pain and other phenomena. And bite mango directly, it is easy to dip the juice on the mouth or face skin. If the juice remains on the skin for a long time, it will have a irritating effect on the skin, and it is easy to cause allergic reactions. Therefore, when eating mango, it is best to cut the flesh into small pieces and send it directly into the entrance. After eating, wash your face with salt water and wash your face in time to avoid the fruit residue.

Although the mango is delicious, it should be noted:

First, don't eat too much at one time. Mango contains very rich protein and sugar. Eating too much at one time can easily cause abdominal distension.

Second, people with allergies eat with caution. Due to the more irritating substances such as fruit acids, amino acids, and various proteins contained in mango, people with allergies or allergies are prone to allergies after consumption, resulting in vomiting, diarrhea, and skin erythema.

Finally, it is recommended that people with high blood sugar eat less. The sugar content of mango is very high. Eating too much can lead to high blood sugar. People with diabetes and high blood sugar should eat less.

Tips:

Teach you 5 tricks to choose mango

Look at the fruit shape: Because the nucleus of the mango is relatively large, you should try to choose a small mango as much as possible when choosing a mango so that you can eat more flesh. From the fruit shape, the size of the fruit nucleus can be judged. Generally speaking, the fruit shape is relatively small, and the nucleus with a short and thick mango has a thick nucleus.

Look at the skin: Mango is uniform with yellow and orange in skin, smooth epidermis, no black spots around the fruit, and it feels solid when touching. If the skin is green, the epidermis is astringent, or there is black spots around the epidermis and the epparer, it is immature mango or a mature mango.

Look at the fruit: When buying, you can use the hand to pipe the fruit. If it feels hard and elastic, it is a mature mango; and the fruiting part is strong or too soft to indicate that the quality is not good.

Look at the flesh: Cut the mango. If the nucleus is found to be hard and the flesh is yellow, it means that the fruit is mature; if the nucleus is still soft, and the flesh is white, it means that the fruit is not mature.

Trying the floating: identifying the mango can also use the method of putting in the water in the water. If the mango is put into the water, it is sinking or sinking, indicating that the mango is mature; and if the mango floats on the surface, it means that the mango is not mature.
