How To Tell if Cantaloupe is Bad?

Cantaloupe is one of the most popular fruits. Its strong rind protects it and makes it much more durable than soft fruit like raspberries.

Those qualities and its distinctive sweet taste make it standby in many home kitchens. Because of its ubiquitousness questions abound about the fruit. How do you know when cantaloupe is bad?

The first sign of bad cantaloupe is moldy spots. If the cantaloupe is not moldy but has large discolored areas, it is also bad. In addition to that, the cantaloupe will also feel soft and may feel hollow. Generally speaking, it is best to throw out any cantaloupe that feels soft and mushy.

How to Tell When Cantaloupe is Ripe

Many people who have never tasted good, ripe cantaloupe think the fruit is bland and tasteless.

But if you know what signs to look for, you don’t have to settle for bland cantaloupe.

White spots on cantaloupe can indicate a common fungal infection known as powdery mildew, which affects various parts of the melon plant. These spots start as small white patches and can develop into larger areas of powdery white growth. While this primarily affects leaves and stems, it can also impact the fruit’s rind, potentially affecting its quality and taste. It’s important to inspect cantaloupes for these spots before purchase, as they can signify the early stages of spoilage or poor quality.

What Does Spoiled Cantaloupe Taste Like?

The best way to determine whether or not a cantaloupe has spoiled is to know what good cantaloupe should test like.

Ripe cantaloupe, also known as musk melon or a rock melon, should have a distinctly sweet flavor and pleasing consistency.

Spoiled melon will often have an off sour or unpleasant bitter taste. The texture of the fruit will be soft, mushy, and mealy.

Small mold spots can be removed by simply cutting them away.

You should always wash your knife after you cut away mold spots before moving on and cutting the rest of the cantaloupe.

The larger the mold spot is, the more likely the flavor of the rest of the melon will be affected by the mold.

What Does the Inside of a Bad Cantaloupe Look Like?

When you cut a healthy ripe cantaloupe in half you will see a well of seeds surrounded by a ring of a distinct kind of orange.

The seeds will be in a mesh-like bed in the center well of the melon.

Any color other than orange, is sign that the cantaloupe is bad. If the color is green, the cantaloupe is likely very under-ripe. Any black spots on the melon’s flesh are more than likely mold that has come into the fruit through the skin.

These moldy spots should be carefully removed.

Sometimes, part of the cantaloupe, especially near the stem can be white if the melon is under-ripe.

The parts aren’t necessarily bad for you, but they will not taste like good, ripe cantaloupe.

What Do the White Spots in Cantaloupe Mean

Occasionally a ripe cantaloup will have white spots in the orange flesh. These kinds of white spots are usually an indication of mold and are usually a sign that the melon should not be eaten.

You will not necessarily get sick if you eat a very small amount mold.

If there are only one or two white spots of mold on the cantaloupe, you will be perfectly safe cutting away the mold, washing your knife and eating the rest. If the melon shows any other signs of spoilage, it is best to discard the fruit.

Questions on Storing Cantaloupe

If your cantaloupe is not yet ripe, leave it out on the counter a few days to let it ripen. Enclosing the melon in a paper bag can help it ripen a little bit faster.
It is also important to remember to wash the melon before cutting it up.
\While the rind is not edible, it will have bacteria or dirt on it and washing it will keep most of it off the fruit that you do it.

How Long Does Whole Cantaloupe Last?

Factors that impact how long a whole cantaloupe can last are the temperature where it is being stored, how ripe the cantaloupe was when it was purchased and what other fruit are in proximity to the melon.

In the summertime, when temperatures are higher, cantaloupe will ripen faster.

Cantaloupes are also more likely to picked when they are already ripe in the summertime and can be picked closer to most grocery eliminating the need for long travel times.

Some fruit, like apples will emit a gas called ethylene as they ripen. Ethylene gas will cause other fruit near it to ripen more quickly.

Bearing those factors in mind, whole cantaloupe can typically last on a countertop for three to five days. If stored in a refrigerator, cantaloupe can last much longer, up to three weeks.

Can Overripe Cantaloupe Make Sick?

Listeria can sometimes be carried on the outer rind of the melon and a thorough washing will typically get ride of any risk of infection.

There is an important distinction between getting sick from a bacteria like listeria and getting sick from a ripe cantaloupe.

Listeria and other bugs live on the skin of the melon and are introduced to the fruit when the skin or rind is not properly cleaned.

If the cantaloupe is properly cleaned, and stored, and the only concern is eating an overripe cantaloupe then you cannot get seriously sick.

The taste and texture of the fruit will be off putting and will hopefully deter most people from eating too much of it, but outside of a bad taste in the mouth and possibly a slightly upset stomach, over ripe cantaloupe does not pose a serious health threat.
