There are black spots on the surface of my apples. Can I eat the skins? Answer:
The black spots are probably sooty blotch or flyspeck. On apples, two distinct fungal diseases called sooty blotch and flyspeck frequently coexist. On the surface of the apple, sooty blotch appears as dark brown to black, 12 inch or larger smudges. Flyspeck produces clusters of shiny, round, black dots. Individual dots are about the size of a pinhead. Late summer and early fall are prime times for disease development due to the environment’s moderate temperatures and prolonged wet periods.
Flyspeck and sooty blotch reside on the fruit’s exterior. Damage is mainly cosmetic. Apple skins can be eaten, but they don’t look very appetizing.
Fungicides and cultural practices can both aid in the management of sooty blotch and flyspeck. Pruning apple trees correctly and fruit thinning encourage drying and lessen the severity of disease. Fungicides may also be necessary. Category:

Fungal Infections Cause Brown Spots on Apples
The apple’s skin develops sunken brown spots as a result of this fungus. As the fruit ripens, the brown spots expand and darken in color.
The flesh beneath the brown spot is also impacted and develops a cone-shaped pattern of browning, with the small end pointing toward the center. As the fungus grows over time, the entire fruit will eventually turn black and shrivel up.
In the early stages of bitter rot, you can still eat parts of the apple that are unaffected. Use the apple’s remaining parts after removing the bitter rot-affected areas that are brown.
Eat or process the apple right away after picking it because the rot will continue to spread quickly throughout the fruit. Affected areas will taste bitter.
A sooty fungal infection known as flyspeck, which resembles the tiny black dots that flies leave behind, is what causes the condition.
Can you eat the apple affected by flyspeck? Yes definitely. The inner fruit is undamaged by the fungus. Even though it is safe for humans to consume, it is advised that if the infestation is severe, you peel the fruit before eating it.
A fungus called cedar apple rust causes brown spots to appear on the skin and brown, spongy flesh to develop just beneath the skin.
Cedar Apple Rust does not cause harm to humans, so you can eat an apple that has been affected by it. However, the brown areas have a mildly bitter taste, so you might want to remove them before eating or cooking the apple.
A fungus called “Apple Scab” causes hard, brown lesions or bumps to appear on the skin.
You can undoubtedly eat unaffected apple parts, but you shouldn’t eat Apple Scab-affected apples. Peeling the apple will leave you with a perfectly healthy and safe-to-eat apple because this fungus cannot penetrate the skin.
You could just skip the few lessons if there are any and eat the remaining apple skin and all.
Black Fruit Rot, which begins at the bottom of the apple where the blossom was, is a blossom end rot. It makes the fruit turn brown, first at the bottom and then eventually affecting the entire fruit.
The apple will turn black once it has completely turned brown. The fruit remains firm throughout the process. Internal rot can result from the fungus moving further into the fruit’s core.
If Black Fruit Rot has just started to develop in an apple, you could cut off the brown bottom end and eat the rest of the fruit. Unfortunately, you shouldn’t eat an apple once it has turned brown.
Dusty black or gray spots on the apple are the result of the sooty blotch fungus.
Apples with Sooty Blotch, a fungus that is harmless but unsightly, can be eaten. However, it is still advised to peel the apple before eating. The inner flesh is unaffected by the fungus.
What Causes Apples To Turn Brown Inside?
An apple’s interior color can change for a variety of reasons, and determining the cause isn’t always simple. If an apple has brown flecks or areas inside but the skin is firm and undamaged, this could be due to:
Any brown flecks on bruised skin are likely the result of oxidization, which can produce mushy flesh with an unpleasant, watery, or bland flavor. If this occurs, you might want to remove that portion of the apple.
To help you understand what causes browning and whether it’s safe to eat the fruit or not, let’s examine each of these possibilities in greater detail.
Incorrect Storage Procedure Cause Apples To Have Brown Spots
Apples kept at a very cold temperature for more than two or three months start to get brown spots. This is also known as storage scald.
You can eat apples with these brown spots on them if they have Superficial Scald. The more time they spend in storage, whether it is hot or cold, the larger the spots will get.
Long-term cold storage causes apples to lose some of their flavor and crisp texture, but they are still edible.
When apples are washed in sodium hypochlorite, food-grade bleach, before distribution, sodium burn can happen. This can also cause brown spots on the skin.
The EPA has approved the use of sodium hypochlorite in food processing, so you can eat the apple that has suffered from sodium burn. Large amounts of sodium hypochlorite exposure can result in headaches, lightheadedness, nausea, and vomiting. Therefore, it is advised that you avoid eating apples that have been harmed by excessive sodium hypochlorite use.
When stored, high CO2 concentrations cause CO2 damage. Some varieties and apples harvested later in the season are more likely to have it.
It causes the inside of the apple to turn brown. The apple appears perfect on the outside, but when it is cut open, the flesh is brown and ugly.
Can you eat an apple with CO2 damage? As an apple ripens, its starches transform into sugars, and CO2 is naturally released.
This CO2 can accumulate in a closed storage space and has been shown to delay fruit ripening. However, if the CO2 levels increase too much, the fruit may be harmed.
There is no proof that fruit can become harmful when exposed to high CO2 levels, but some studies have shown that it can reduce the fruit’s nutritional value.
As a result, eating an apple is safe, and you might only need two to get the necessary nutrients.
When apples are kept at temperatures that are too low for them to handle, soggy breakdown results. This causes browning in the cortex.
It can result in a ring of brown around the entire apple or some brown spots just below the skin. When the apple is cut open, it can be seen even though it typically does not reach the skin.
Is it safe to eat an apple that has experienced soggy breakdown? Due to cellular breakdown, the browning beneath the skin is harmless to people. Although it is unsightly, it does not seem to have an impact on the apple’s flavor or nutrition. Some of the crisp texture may be lost.
When apples are stored at temperatures below their tolerance, soft scaling, another chilling disorder, develops. It looks like a light brown blister on the skin.
With time, it will turn darker and have an impact on the flesh underneath. And it will eventually cause fungal decay.
If the soft scald is caught in the early stages, you can still eat the apple. It is safe to eat it or simply cut the blister away. When fungus decay has begun, it is best to remove the infected area by cutting. It is best to avoid the apple if a sizable portion of it has been infected.
