Can you eat mango after it has been cut and left for a long time to change color

Slightly oxidized and blackened can be eaten.

The pulp of mango contains polyphenol oxidase, once the cell tissue is damaged after peeling, the phenolic substances in the mango will be oxidized to brown quinones when they contact the air, and the black appearance will be released on the pulp, but it will not produce any toxic substances, just cut off the blackened part to continue to eat, but if the blackening is more serious, then do not eat, indicating that the time is too long, the mango has been rotten and deteriorated, and eating it is not good for health. Usually, the mango that was cut the day before is no problem to eat the next day. The mango should not be more than 2 days after it is cut.

It's best not to eat it, if you want to eat it, cut off the black one on the outside, it's oxidized, and I personally think it's better not to eat it.

If it is normal yellow when it is cut, and now the epidermis is a little black, it should be oxidized, you can smell it, if there is no odor, it should be okay.

It may be that it will be more ripe before it will become this color, and as long as the taste remains the same, it should not be a big problem.

After peeling apples, pears and other fruits, their color will change quickly due to contact with air, and they can be made up if they are eaten alone, but if they are used to entertain guests, they are not very beautiful, and the discoloration of fruits is due to the action of enzymes. This can be changed by dipping freshly peeled fruit in brine.

Under normal circumstances, the green mango will begin to turn yellow after about half a month.

If it has not turned yellow for a month, it will gradually start to deteriorate, and if it is stored in a low temperature environment, after a month, it will also begin to gradually decay.

Green mango is different from other varieties of mango, not only is it larger, but the color of the ripe green mango is also green, and it will not turn into a golden mango, so judging whether the green mango is ripe mainly depends on the hardness of the mango.

How to ripen green mango:

1. We can buy one or two ripe bananas, put the ripe bananas and green mangoes together in a plastic bag, and then tie the plastic bag tightly and put it indoors, so that it can be put for a day or two.

2. You can put it in a rice bowl, bury it with rice, cover it with a rice bowl, and the mango will be ripe in a few days. Because rice also contains ethylene.

I didn't know if the blackened mango could be eaten before, but today I will give you the correct answer.

Generally speaking, if you cut a mango, the flesh of the mango will produce some oxidation reaction after contact with the air, and the oxidation reaction will cause the flesh of the mango to turn black, so if you want the mango you consume is not easy to turn black, you have to do a certain amount of effort in isolating the air, you can put it in the crisper box and it will not be easy to turn black.

1. No discoloration in a short period of time (half a day): Clear water preservation method: Place the peeled mango in clean water to isolate the pulp from the air. Appropriate capacity bowl inverted method: If the peeled mango is expected to be eaten in the short term, pick.

2. No discoloration during the general period (about a day): Put on plastic wrap and put it in the refrigerator for refrigeration, and the internal temperature environment of the refrigerator should not be too low.

1. How to preserve the cut mango.

Cut the flesh of the mango into cubes, put it in a bowl, and rub some icing sugar in it, it won't be so sour.

How to preserve green mango:

1.Put it in a rice bucket, bury it with rice, cover the rice jar, and the mangoes will be ripe in a few days.

2.Pickle unripe mangoes, the whole pickle needs to wash the mango, put it in cold boiling water, add an appropriate amount of white vinegar or rice vinegar, salt or sugar to seal it, and you can eat it after a week. You can also wash the mango and cut it into pieces, sprinkle it with salt or sugar, marinate it for a day and you can eat it, it is very crisp, and you can also add chili powder if you like to eat spicy.

3. If the general raw mango only needs to be placed naturally, and it doesn't even need to be sunburned, the mango is obvious to ripen.

4.Put the raw mango in a paper bag, put two more bananas or ripe apples, and then tie the mouth of the paper bag tightly, and the raw mango will ripen the next day, because the ethylene released by the ripe fruit can ripen the raw fruit.

In addition, it should be noted that when the mango is not ripe, there will be white juice oozing from the fruit pedicle, which is estimated to be the cause of allergies. Eating too much mango can cause allergies, and in severe cases, it may damage the kidneys. Do not eat mango after a full meal.

Mango should not be eaten with spicy substances such as garlic, otherwise it may cause yellowing disease.

2. Contraindications for mango consumption 1. Mango and garlic and other spices cannot be eaten together Mango contains fruit acids, amino acids, proteins, etc2. Mango and pineapple should not be eaten together These two fruits are not eaten together.

Cultivate a calm heart. When people reach a certain age, they will become peaceful, and they will no longer be the nine cows that lost their temper in the past.

And through the hot post and he one.

How do you save it without discoloration after helping me cut it? I feel like this is washed with clean water so that it doesn't change color again. It's a nice little knock.

If you want to eat it in a short period of time, you can use the water preservation method: the peeled mango is placed in clean water to isolate the pulp from the air.

Cover with plastic wrap and refrigerate in the refrigerator, and the temperature in the refrigerator should not be too low.

Hello, you can put plastic wrap on the cut and put it in the refrigerator.

To achieve great achievements, you must obtain some small achievements every day, because big achievements are small achievements.

I'm sorry, we can't do this question, you can ask the people around you or go to the relevant unit, I wish you a happy life.

When the mango turns black after being cut, it is a browning reaction.

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 phenols and quinones), 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 quinones occur to form black.

Mango is a tropical fruit, so you have to eat it quickly after cutting it, and it will become moldy and black after a long time. I can't eat it at all.

Mango contains an enzyme that undergoes an oxidation reaction when dissolved in water, so it turns black. Therefore, fresh fruits are best handled in time, or refrigerated to keep them fresh.

Let's see what others have to say.

Because it's been a long time, mango and air. You can't eat it.

It may be spoiled, and it is better not to eat it.

If it is too long, it is impossible to eat.
