What Are the Brown Lines in Mangoes?
Brown lines in mangoes may be produced by three factors. The first is heat damage, which occurs when mangoes are placed in a hot water bath to kill fruit flies, producing interior browning. Second, extreme cold storage could be to blame. Third, it could be caused by Resin Canal Discoloration, a bacterial-caused darkening of the mango’s normally flesh-colored vascular canals. Although it may seem unappealing, the mangoes in both of these examples are safe to consume.
What Causes Brown Lines in Mangoes?
Mangoes would always be juicy, luscious, and the perfect golden yellow color in an ideal world. Nevertheless, this is not always the case. Mangoes, like other fruits, are susceptible to pests and bacteria and may be affected during storage and handling.
If your mangoes have begun to appear ominous and have grown brown vein-like lines, the three explanations listed below are possible culprits.
1. Hot Water Treatment
All mangoes imported into the United States must go through a hot water treatment to guarantee that no foreign pests, such as fruit flies, are unintentionally introduced into the nation with the mangoes. This measure is required to safeguard the country’s plant and animal life. This procedure is overseen by the Animal and Plant Health Inspection Services, or APHIS.
The Process
The mangoes are transported to an approved facility in the exporting nation and immersed in hot water with temperatures of at least 115 degrees Fahrenheit. This hot water is also chlorine-treated.
The amount of time the mangoes are submerged in hot water is determined by their origin, size and weight, and cultivar. A complete procedure is available here.
Following dipping, the mangoes are allowed to cool in a controlled atmosphere before being transported to an insect-free facility where they will remain until ready for export and distribution.
The hot water treatment raises the temperature of the mango pulp and eliminates any bugs that may be hiding inside it, enabling it to last longer. It also destroys any larvae or eggs that may be hidden on the mango’s surface and causing difficulties later on.
Why It Can Cause Problems
Hot water treatments may cause internal harm to the mango, which may appear as browning of particular portions, including the vascular canals known as resin canals, if the mango is immersed for too long or if the mango is very fragile.
Browning may be caused by a disturbance in the usual flow of nutrients inside the mango as a consequence of severe temperatures, as well as by these impacted chemicals interacting with each other, resulting in a change in the mango’s color.
Mangoes with interior damage may spoil quicker, but for a limited time, they are edible and safe. If the browning isn’t too severe, you can consume them, or you may clip away the discolored sections and eat your mango as is.
2. Extremely Cold Temperatures
Mangoes are a tropical fruit that does not enjoy chilly weather. Very cold temperatures may damage the mangoes’ cell walls and internal feeding system, allowing chemicals to seep out and interact with one another, resulting in browning and various discoloration on the flesh and peel.
Although some cold is required for preservation, it is achievable, particularly if the mangoes are maintained under cold circumstances for an extended length of time.
Similar with heat damage, damage produced by intense cold will not pose a health risk, so just chop away the discolored sections and consume your mango as usual.
3. Resin Canal Discoloration
Finally, brown lines in mangoes might be induced by Resin Canal Discoloration.
The Resin Canal Discoloration is a problem in which red-brown or black vein-like lines emerge on the flesh (and occasionally the skin) of afflicted mangoes, and if severe, it might seem as if your mangoes are infected with tiny worms or are becoming wicked.
It is often seen on the flesh of mangoes, although it may also be observed on the skin.
What Are Resin Canals?
Resin canals are a network of small tubes in the mango fruit that are assumed to be part of the fruit’s defensive mechanism, storing and transferring any essential components.
Generally, they are the same color as the mango flesh, so you don’t see them. But, if the mango is infected with RCD, it may appear as brown-black lines that resemble little worms.
What Causes Resin Canal Discoloration?
For a while, experts and producers were perplexed since the source of this dreadful illness in mangoes was unclear, but it appeared to occur more often post-harvest, to harm particular cultivars more than others, and to occur more frequently as the mangoes matured.
Bacteria were revealed to be the source of the sickness a few years ago in Australia. This was excellent news for producers since precise steps to limit the spread could subsequently be implemented, and this information gave improved possibilities to preserve their harvests and sales. So, although damaged mangoes are safe to eat, they lack hunger appeal.
Are Brown Lines in Mangoes Safe to Eat?
Brown lines in mangoes are safe to consume if induced by any of the factors listed above. Seeing small vein-like things in your mangoes may not be the most pleasant thing in the world, but it won’t kill you.
If it is just a tiny area of the mango, you may cut it away or avoid eating it entirely if it has invaded the majority of the surface. I don’t blame you one bit!
How Do I Know If Mangoes Have Gone Bad
Brown lines in mangoes are not dangerous to your health, but it is a good idea to look for other signals that the mango is still safe to consume before proceeding.
The following are some warning indicators to look for to determine if your mangoes are still edible.
1. Texture
Mangoes should be tender yet firm to the touch when they are fresh and ripe. They are overripe if they are excessively soft and mushy. Overripe mangoes are acceptable to consume for a short time, but they will be sweeter than normal and the texture will be less appealing since they will become too mushy at some point.
2. Smell
When the sugars in the mango ferment over time, they may produce off scents and odours, and may even smell alcoholic. If you discover a peculiar odor on your mango, throw it away.
3. Appearance
Some discoloration is to be anticipated from mangoes as they age, as well as how they are handled and maintained, and they may not necessarily make you ill, but if you find an excess of black spots with liquid leaking out, or if you detect mold or broken skin, it is better to dump it.
If you are doubtful, I recommend that you err on the side of caution and trash it. Mangoes should always be juicy, pleasant, and tasty. What’s the purpose of eating a mango if it’s not any of these things?
How to Store Mangoes
Unripe or almost ripe mangoes may be kept at room temperature in a brown paper bag for a few days to ripen.
Mangoes may be stored in the refrigerator once ripe for a week or two if kept whole. They will only survive a few days once cut since the interior has already been exposed to oxidation.
Unripe or less-than-ripe mangoes should not be refrigerated. They may not ripen fully in the fridge, and you may wind up with a batch of mangoes that are sweet but not quite there.
If you want to keep them for a longer period of time, peel them, cut them into cubes, place them in a freezer bag, and freeze them. Keeping them in this manner makes it easy to include them into smoothies and other dishes.
Frozen mangoes may be stored in the refrigerator forever, but for the greatest quality, utilize them within 6 months. Likewise, do not anticipate them to have the same consistency as fresh mangoes when thawed, since freezing changes their texture.
Are Mangoes Healthy?
Mangoes are high in vitamin C, which boosts immunity and assists in various bodily functions such as cell development and repair. It includes vitamins and minerals that support cardiovascular health and may aid in the prevention of diabetes and some malignancies.
It is high in fiber, which promotes digestive health. It has anti-inflammatory properties, antioxidants, and may help prevent anemia and build bones.
Mangoes are not only delicious, but also nutritious.
Conclusion to Brown Lines in Mango – What is It? Safe to Eat?
It’s natural to be concerned when you see brown lines in your mangoes, but as long as there are no other indicators of food decomposition, they’re typically fine to consume.
Very hot and cold temperature fluctuations may cause internal damage to mangoes, leading in browning or darkening of the resin canals. It might potentially be caused by Resin Canal Discoloration, a bacterial-induced fruit disease.
Whatever the source, it is critical to scrutinize and check the food for any unusual looks, aromas, textures, or scents. This way, you won’t be putting yourself at danger of food illness or having the unpleasant experience of eating a rotten mango.
Frequently Asked Questions to Brown Lines in Mango
Are Mangoes Infected with Resin Canal Discoloration Safe to Eat?
If there are no other indicators of food decomposition, they are safe to consume. You may remove the afflicted pieces of the mango and eat it as is.
Are the Black Veins In Mangoes Safe to Eat?
Black veins in mangoes are most likely caused by Resin Canal Discoloration, a bacterial infection in mangoes. It is safe to consume if it is in this state, however it may not be attractive.
FAQs
Why does my mango have brown strings inside?
It’s darkened vascular channels! Toss or eat? You may cut around them if you like, but the mango is still edible.
What is the brown stuff in mango?
If the fruit has black patches on its skin, it has started to decay. The somewhat dark flesh indicates that the fruit has started to rot on the inside. If the meat still smells sweaty and “mango-like,” it’s OK to eat. It is recommended to toss it away if it smells off or like cleaning fluid.
How can you tell if a mango is safe to eat?
Indications that your mangoes should be discarded
Fresh mangos have a hard texture, however ripe mangos may develop mushy areas, according to Chefs Dream. Brown spots or mold on a mango, as well as an unpleasant odor emerging from it, are further indicators that the fruit is rotten or on its way to becoming so.
What are the black things in my mango?
It indicates that the fruit has begun to spoil. When black stains emerge on the side of a mango, it is beginning to decay. The pit, the skin, or the non-stem end of a mango may all rot. Any black threads also signal that the fruit has begun to decay, at which time it should be discarded.
Is it OK to eat mango with brown veins?
Resin canal discoloration (RCD), a mysterious condition for decades, causes odd veins to form inside the mango flesh. Mangoes affected by RCD are safe to consume, but the flaws and discoloration render the fruit almost unsellable.
Why does my mango have strings?
Stringiness in mangoes is often caused by the mango not being fully ripe. Even though the color is beautiful, if the flesh hasn’t completed ripening, it will have more texture, which might contribute to stringiness. Big mangoes may be stringy in certain situations, and some types may have more fibrous skin than others.
What are the weird spots in mango?
If the white spots on a mango worry you, remember that they are an effort to avoid something lot worse: fruit fly infestations. Female fruit flies deposit eggs in the flesh of mangoes, and when the maggots emerge, they consume the fruit from the inside out.
What are the specks in mango?
Due to a shortage of oxygen, the mango’s metabolism starts to accelerate, resulting in the production of alcohol and carbon dioxide. When the carbon dioxide has nowhere to escape, it begins to form little white pockets in the fruit’s flesh.
What to avoid when buying mangoes?
A mature mango will be solid and yield slightly to the touch, thus avoid hard, extremely soft, or damaged mangoes. Mangoes that are wrinkled or shriveled are also overripe and have an awful soured flavor.
What does a mango look like when it’s not ripe?
Answer: When the skin color changes from entirely green to yellow, a mango is ready to eat. Mangos change yellow, orange, red, and purple as they mature, or any combination of these hues.
