Sweet potatoes are a delicious and nutritious addition to any meal. But if you’re not careful, they can be spoiled before you’ve even had a chance to eat them. Here are some signs of a bad sweet potato:

1. Feels soft or mushy

If your sweet potatoes feel soft or mushy, it’s probably time to toss them out. This can be a sign that they have been stored improperly. Make sure you keep your sweet potatoes in a cool, dark place and away from direct sunlight.

2. Spotty appearance

If you find that your sweet potato has spots or blemishes, it may have been exposed to too much light. This can cause the sweet potatoes to turn brown, even if they are still edible.

3. Unpleasant smell

The smell of a sweet potato is one of its most important features, so it’s important to know what a bad smell means. A bad sweet potato will have an unpleasant smell that could be caused by several different factors.

If your sweet potatoes have a rotten smell, then it’s likely that they’ve been stored in too warm of conditions for too long. Sweet potatoes are best stored in a cool, dry place with plenty of ventilation to prevent them from spoiling.

If you’re having trouble identifying whether or not your sweet potatoes have gone bad, you can test their firmness by pressing them with your finger. If they feel soft and squishy, then they’re probably past their prime.

4. Bitter or sour

One of the signs of a bad sweet potato is a bitter or sour taste. If your sweet potato tastes like it has gone bad, do not eat it. The taste of a sour-sweet potato indicates that the tuber has been sitting around for too long, and it will not be very nutritious for you.

5. Dark spots on the skin

If your sweet potatoes have dark spots on their skin, it could mean a few different things. The first is that the sweet potato has been exposed to too much light, which can cause them to go bad. The second is that the sweet potato has been exposed to too much heat, which can also cause them to go bad.

6. Skins are cracked

Cracked skins are a sign that the sweet potatoes have been exposed to too much heat. This can happen in the store or at home, and it’s not a big deal. Just cut away the bad parts and use the rest.

7. The skin is wrinkled.

Wrinkled skin is one of the most common signs of a bad sweet potato. The skin should be smooth and shiny. If you see wrinkles, it’s best to just put the sweet potato back in the bin.

Is it safe to eat old sweet potatoes?

How to tell if sweet potatoes are bad

You can eat old sweet potatoes, but they might not be very good. If you have a lot of old sweet potatoes and don’t know what to do with them, don’t panic. Just because they’re old doesn’t mean they’re bad for you as they just won’t taste as good.

If the sweet potatoes are still in good shape, you can still use them to make some delicious dishes. But if you have a bunch of old ones, you may want to consider composting them instead of throwing them out.

What does expired sweet potato look like?

Expired sweet potato looks like a normal sweet potato, but it may be a bit darker in color and smell slightly off. If you’re still unsure whether your sweet potatoes are expired, cut one open to make sure there’s nothing strange inside (like mold).

If you suspect that your sweet potato has gone bad, you need to know what it looks like so you can throw it away before it gets any worse.

If your sweet potato is black on the outside and white in the middle, then it is still edible and safe to eat. However, if it turns brown with some dark spots on the side, then it should be thrown out immediately because this indicates that there could be harmful bacteria growing inside of it.

What happens if you eat a rotten sweet potato?

If you eat a rotten sweet potato, it will probably make you sick. Rotten sweet potatoes taste terrible, so that’s one reason not to eat them, but they also can cause food poisoning.

That’s because when a potato is in the ground, it is exposed to air and moisture, which causes bacteria to grow on it. That bacteria can be harmful if you eat it.

Is it safe to eat sweet potatoes with black spots?

It’s safe to eat sweet potatoes with black spots. The black spots are simply natural discoloration that occurs in sweet potatoes after they’re harvested.

You can tell when your sweet potatoes have reached their prime by looking for the color change; once they’re orange-ish, they’ve lost their vitamins and nutrients. So you’ll want to avoid those, but you can still eat those with black spots.

Can you cut off the moldy part of the sweet potato?

You can cut off the moldy part of a sweet potato. Mold is a fungus that grows on food and causes it to decay. Mold is usually a greenish-brown color and has a fuzzy texture.

You should not eat any part of the sweet potato that has mold on it. You should also throw away any food that has been contaminated with mold. This includes other fruits, vegetables, pieces of bread, grains, herbs, and spices.

Mold can cause allergic reactions in people with respiratory problems such as asthma or allergies to hay fever. If you have any of these conditions, make sure to wash your hands after handling the food as well as any utensils used in its preparation so as not to transfer any spores onto your skin or into your lungs via inhalation (breathing).

How To Choose Good Sweet Potatoes

Here are some tips to help you pick out the best sweet potatoes at your supermarket:

  1. Choose a potato that feels heavy for its size. Sweet potatoes should be dense, not light and fluffy. A heavy potato will be more likely to have more flesh and less water content than a lighter one.
  2. Look for smooth skin with no blemishes or bruises. Bruises or cuts in the skin can harbor bacteria that may cause food poisoning.
  3. Make sure the skin is firm and shows no signs of shriveling or softness, which could mean it’s been sitting around too long (and thus isn’t as fresh).
  4. Avoid sprouted sweet potatoes as they may be moldy inside and can cause digestive upset in some people.

How To Store Sweet Potatoes?

Sweet potatoes are a delicious and healthy part of any diet. They’re also easy to store and use throughout the year.

  1. Store in a cool, dark place that’s not too humid.
  2. Keep them unwashed and unpeeled until you’re ready to eat them.
  3. Don’t put them in plastic bags because this will cause them to rot faster than if they were kept out of the bag in a paper bag or basket.
  4. If you have more than one sweet potato, cut one up into pieces and store each piece separately, so they don’t start to rot before you get around to eating them.
