Brown spots inside an apple are not a reason for concern. The apple is safe to eat as long as there are no signs of mold. However, it's best to avoid fruits with bruises, skin breaks and other signs of damage, as they are prone to mold.
"Someone who is particularly sensitive or who gets sick from moldy fruit may experience nausea, vomiting or diarrhea as well as other food poisoning symptoms." She also cautions that some types of mold are more dangerous than others.
brownApples that have become rotten will be very mushy and brown in color.
Check Skin Color for Overripe Apples Mature apples usually change from their original color to another, meaning they're overripe. Green apples turn yellow, reds turn green or yellow, and yellows turn to white. This color change means they are on the verge of being old, so eat them as soon as possible.
Although not a perfect test, your senses are usually the most reliable instruments to tell if your apples have gone bad beyond the shelf life. Some common traits of bad apples are a grainy, soft interior and wrinkled skin along with discoloration and bruising. Avoid any apples with mold on the bottom.
Fresh apples have a bright, fruity aroma, shiny skin, and firm flesh. If the skin is wrinkled and the texture grainy, but otherwise everything is okay, the apple is still okay to eat. But it won't taste that great on its own.
The most common causes of apple rot are from the fungi Penicillium expansum and Monilinia fructigena. These fungi feed on and kill the cells that make up the apple. The fungi produce pectic enzymes that break down apple pectin to expose the nutrients of the cells to the fungi.
Here are a few indications that an apple has begun to go bad:soft spots or bruising.wrinkled skin.holes and brown blemishes.liquid oozing from its skin.a mushy texture.a mealy or bland and grainy taste.Feb 5, 2020
There are also brown spots inside the apple's flesh. It is caused by a calcium deficiency in the fruit and can appear while the fruit is still on the tree or appear within the first month or two of cold storage.
It's best to discard apples that are soft or show other physical signs of expiration, as moisture content under the skin can indicate contamination (5). You can usually tell whether an apple has started to go bad by examining its appearance. Apples that have gone bad should be discarded.
Moldy core (also known as dry core rot) begins to develop while the fruit is on the tree. It is caused by Alternaria and other species of fungi, which enter the fruit and grow in the seed cavity. Dry, spongy brown lesions extend from the core, but rotting symptoms do not develop.
Apples turn brown because of a chemical reaction called "oxidation", which is caused by oxygen from the air. Oxygen is one of the most reactive chemicals known, and there are many kinds of oxidation reactions. The fridge does not stop chemical reactions, so bacteria will still rot the food eventually.
Depending on the infecting fungi, some moldy core can turn into core rot, but this does not happen all of the time. If you encounter an eating apple that has moldy core and not core rot, the flesh is still eatable should you choose to eat around the core. Consequently, these apples are perfectly fine and disease-free.
Fruits like apples can rot and decay over time. Mold and fungus cause the quickest degradation, but even exposing an apple to heat can cause it to oxidize. Bruises and punctures offer the quickest route for mold and fungus to take hold. Different pathogens have different effects on rotting apples.
Moldy core (also known as dry core rot) begins to develop while the fruit is on the tree. It is caused by Alternaria and other species of fungi, which enter the fruit and grow in the seed cavity. The mite Tarsonemus confusus can carry the fungal spores into the fruit through the calyx. The spores germinate during rain.

Is there any truth to the expression, "one rotten apple spoils the whole barrel"? You bet. Because once an apple is rotten or has physical damage, (ie a bruise), it produces ethylene, which in turn leads to a slightly increased internal temperature causing a breakdown of chlorophyll and the synthesis of other pigments.
Oxidation. Apple flesh has chemical compounds known as phenolics that react with oxygen when exposed to air. Once the skin of the apple is broken, the compounds are exposed to oxygen and enzymes in the apple known as polyphenol oxidases cause the browning reaction.
This unappetizing phenomenon is actually due to a chain of biochemical reactions known as “enzymatic browning.” When an apple is injured (or cut into pieces), the plant tissue is exposed to oxygen. This triggers an enzyme known as polyphenol oxidase (PPO) to—wait for it—oxidize polyphenols in the apple's flesh.
Pectin helps control blood sugar and cholesterol levels, which means you should indulge in the forbidden fruit a lot. But once again, not at night. Why? Because pectin is hard to digest, and since you won't be exercising after dinner to help your body metabolise it, it can lead to acidity.
When an apple is cut (or bruised), oxygen is introduced into the injured plant tissue. When oxygen is present in cells, polyphenol oxidase (PPO) enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.
Unfortunately, many of the fruits rot and go mouldy even before they are fully ripened. The fruits rot from the inside, and remain in part hanging in their mouldy state on the tree.

Bananas, oranges, apples, all kinds of food and fruit do biodegrade, but you have to remember that it doesn't happen instantly.
When you are managing bot rot of apples, pruning off all dead wood is important. After pruning apple trees, consider using a fungicide as a preventative. Using fungicidal sprays is especially important in wet years.
Turns out this is a scientific truth that when one rotten apple is exposed to ones that are not it will cause the fruit to ripen faster and eventually rot. This is because as apples ripen they give off a hormone in a gaseous from called ethylene which is a catalyst for ripening fruit.

When we begin to transition to writing things sequentially, we are just learning to drop a few details along the way. Sequential order on the other hand, is ordering things in in a step in a process or events. When writing in this form it is ideal to outline a clear plan for what you are going to put together.
