In this brief guide, we will answer the question, “how to tell if potatoes are bad” and discuss when does potato go bad, and what are the tips to store potatoes for a long time?

How to tell if potatoes are bad?

Here are a few ways to tell if potatoes are bad:

If you’re wondering how to tell if potatoes are bad, you might be suspicious of the smell. If your potatoes smell like rotten eggs or other unpleasant odors, they may have gone bad. To test for this, cut off a small piece and smell it. If the potato smells strongly of ammonia, it’s probably bad.

If you see green or black spots on your potatoes, they’re spoiled. The green and black spots are usually caused by a fungus called Aspergillus, which can be found in soil and water. The fungus can also be present in other foods. If you see these spots on potatoes or any other produce, toss them out immediately.

You should also avoid potatoes that have brown or wrinkly skin because it could mean the potatoes were damaged at some point during processing. For example, if the skin around your potato’s eyes is wrinkled or discolored, it may have been damaged during harvest or storage. 

If it has turned brown, it’s probably beyond its prime. Potatoes will brown if they’re exposed to air for too long or don’t have enough moisture in them. If you cut into a potato and the flesh has turned brown, throw it out and go get another one!

If you have a hard time slicing through the potato without getting a chunk of skin stuck on the blade, then that means that your potato is no longer fresh. It should be easy enough to slice through with just a little pressure and effort. If this doesn’t happen easily or at all, then it’s time to ditch that potato!

When does potato go bad?

Potatoes go bad when they start to show signs of decay: sprouting, rot, or mold.

If you see any of these signs, toss it out! Potatoes will last well up to six months in your pantry if kept at room temperature, but they won’t taste as good after they’ve gone bad.

Potatoes can be stored at cool temperatures (32-45 degrees Fahrenheit), but they’ll stay fresh for longer if refrigerated. They’re best kept in an airtight container with a humidity-proof lid so that moisture doesn’t get trapped inside the package and cause your potatoes to spoil. It’s also a good idea to inspect your potatoes before you use them, if you find any cracks or holes in them, throw them out immediately!

How long do potatoes last at room temperature?

Potatoes can last for at least 14 days at room temperature before starting to lose flavor and nutrients.

Potato products that are sold in grocery stores usually have a label that tells you how long it will take for the product to lose its crispiness and become soggy. The key thing to remember is that potato products are best eaten within 2 weeks of when they were purchased.

What are the tips to store potatoes for a long time?

If you’re looking to store potatoes for a long time, you have a few options. You can freeze them, you can keep them in the fridge, or you can dry them out and keep them in an airtight container.

Freezing works best for large-sized potatoes that are less than 1 inch thick and have a hard skin. The best way to freeze them is to put them in a freezer bag and seal it tightly, making sure that none of the air is able to get in through any holes or cracks. You can also put a layer of wax paper between the bag and the potatoes if they’re particularly large or heavy.

If you want to keep your potatoes in the fridge, it’s best if they’re cut into pieces no larger than an inch thick, otherwise they’ll end up getting mushy after being stored too long. Store those pieces on a plate lined with paper towels so they don’t stick together with moisture from condensation from other foods nearby!

Finally, if you’re not planning on using any of your potatoes right away, try drying out your potatoes so there will be no moisture to spoil them. Then store the potatoes at room temperature.
