Can an avocado go bad?

Avocados are a pricey fruit, and getting a good deal on them isn’t easy. But you were prepared when you saw one at the farmers’ market or your local grocery store.

You’ve acquired a lot of avos rather than the usual two or three, and you’re concerned that some won’t last long enough for you to consume them.

Can avocados go bad?

Yes. An avocado can go bad if it is exposed to air, moisture, or heat for an extended period of time.

The signs that avocado is bad to include brown spots on the skin, darkening of the flesh, and a sour smell. It is time to toss it out because the rich and creamy texture would no longer be present. 

If you notice any of these signs, do not eat the fruit.

How can you tell if an avocado is bad?

Avocados don’t ripen once they’ve been plucked from the tree, but the transformation is quick.

You have a narrow window of time — usually several days — before the fruit begins to decay after it has ripened.

Eating an avocado after the optinal consumption period probably will not give you the best texture and color, but flavor and nutrients tend to stay almost the same. 

And you may be wondering how to tell whether an avocado is rotten and no longer safe to consume.

Here are the signs that avocado is no longer safe to eat:

Mold on the outside of the fruit

Mold is an indication that the avocado has gone bad. The entire fruit should be discarded since mold may spread through the soft flesh but not be entirely visible.

If you notice mold on the skin of an avocado, don’t buy it; it might get inside and cause deterioration.

Decaying or soft flesh

When determining ripeness, use your palm to softly press the avocado. Don’t apply pressure with your fingers since this may bruise the fruit.

Unripe avocadoIf the avocado is very firm and does not give, it is underripe.

Ripe avocado – It’s probably ripe and ready to eat if it gives a little, with green skin color.

Overripe avocados – If pressing leaves an indentation, it’s probably too ripe for slicing and will taste better mashed or juiced.

Spoiled avocado – If you press fruit that leaves a large dent and the substance feels mushy, it’s probably beyond saving.

Rotten avocados – Additionally, if an avocado has signs of rot, such as a sunken area or appears deflated before you squeeze it, it’s probably past its prime.

Brown or black spots on the skin

Avocados with brown, black, or dark spots,  often called flesh discolorations, occur when the avocado has been exposed to cold temperatures for an extended period of time before it begins the ripening process.

A light-colored avocado is unripe, while a darker one indicates that the fruit is ripe.

Darker spots on the skin indicate that the avocado was stored in colder conditions, so it’s likely to be less flavorful.

Some avocados undergo distinct color changes as they ripen, particularly the Hass variety, accounting for about 80% of the world’s avocados consumed.

Flesh bruises can occur in transit or due to compression caused by excessive handling.

Never fear if you cut into a less-than-ideal avocado and notice those ugly black spots. You have to cut them out with your kitchen knife or spoon.

Late in the season, when avocados start to over-ripen due to their high oil content, they can also develop brown spots.

An off odor

Ripe avocados have a pleasant, somewhat sweet scent and flavor reminiscent of nuts. The fruit may acquire an unusual taste and fragrance as it spoils.

If the fruit has a sour taste or noxious odor, it is likely harmful bacteria spoilage and should be discarded.

The rotten chemical odor and taste might indicate that it is rancid. This rancid odor may occur when oxygen or microorganisms weaken or destroy the fruit’s unsaturated fat.

Rancidity in avocados can produce potentially deadly chemicals. If you believe an avocado is rancid, don’t eat it.

Dark, stringy flesh

A fresh avocado will smell lightly fruity inside, and be a clean, light, or medium green color. 

An avocado has light green flesh when it’s ready to eat. A decayed avocado has brown or black spots and a stringy texture throughout the flesh.

However, a brown avocado with an isolated brown spot might be caused by bruising rather than widespread spoilage, and it may be cut away.

Dark streaks in the flesh are another sign of rotting.

However, some avocados — particularly those picked from young trees — might have dark streaks even when they’re not rotten. It’s fine to consume fruit that looks perfect otherwise and does not have an abnormal taste.

How long do avocados last?

Ripe avocados can be stored in the fridge for two to four days. If you’re not going to use an avocado right away, keeping it in the refrigerator will slow down the ripening process.

If you have cut avocados, you can wrap them in plastic wrap as tight as possible or store them in an airtight container and keep them in the fridge for one to two days. It can last two or three days if you’ve squirted some lemon juice into it. 

Can you freeze avocados? How to do it?

Yes, you can freeze avocados.

To freeze them, first cut the avocado in half and remove the avocado pits. Then, place the avocado halves in a single layer on a baking sheet and freeze for two hours.

After two hours, remove the avocados from the baking sheet and place them in a freezer bag or container.

Avocados can be frozen for up to six months. When you’re ready to use them, remove them from the freezer and let them thaw at room temperature.

What if I ate a moldy avocado?

When does avocado go bad?
