Have you ever cut into a sweet potato and found white areas inside that look dry and stringy? This common issue has left many home cooks wondering are pithy sweet potatoes safe to eat?
Pithy sweet potatoes are generally safe to eat, as pithiness is a texture change caused by age or improper storage rather than harmful bacteria or toxins.
While the pithy parts may taste less flavorful and have a dry, stringy texture, they pose no health risk and can be consumed, though many people prefer to cut away the affected areas for better taste and texture.
Sweet potatoes are a staple food in many households across North America. These versatile root vegetables can be prepared in a variety of dishes from sweet potato fries to sweet potato casserole.
When stored properly in a dry place, whole sweet potatoes can last a long time – often a couple of weeks or more. But sometimes, even seemingly fresh sweet potatoes develop a condition called “pithiness.”
The white substance or dry areas inside might look concerning, especially when you’re planning to cook sweet potato recipes for your family. Many people immediately worry about food poisoning and toss the affected areas.
But let’s explore what causes pithy sweet potatoes, how to prevent it, and how to get the maximum shelf life out of your root vegetables.
What does a pithy sweet potato look like?
A pithy sweet potato looks dry, stringy, and sometimes hollow inside.
Instead of the smooth, moist flesh we expect from good sweet potatoes, it can seem rough and shriveled. You might see gaps or tiny holes called hollow heart.
This happens when sweet potato roots grow in high temperatures or the wrong conditions. It’s more common in orange sweet potatoes and purple sweet potatoes grown outside ideal conditions like a cool, dry place.
When buying at the grocery store or checking your vegetable garden harvest, look for signs of spoilage of sweet potatoes like brown spots, soft skin of sweet potatoes, or a weird white sap.
Whole sweet potatoes stored the right way — in a root cellar or a dry place around 55 degrees Fahrenheit and the right relative humidity — can last a couple of weeks.
If you see any of these signs, it may indicate that the sweet potato is no longer safe to eat.
How long do sweet potatoes last?
Whole sweet potatoes can last a long time if stored correctly. In a dry place around 55-60 degrees Fahrenheit, they stay fresh for a couple of weeks to even a few months. A root cellar offers ideal conditions for storage.
If you leave orange sweet potatoes or purple sweet potatoes at high temperatures, they spoil much faster. Spoilage of sweet potatoes often shows through white sap, brown spots, or wrinkled skin of sweet potatoes.
Raw sweet potatoes should feel firm, just like regular potatoes. Fresh sweet potatoes from the grocery store or vegetable garden are a great option for making sweet potato fries, sweet potato casserole, or various dishes like savory dishes with black beans.
Bad sweet potato signs include hollow heart and odd smells. To keep good sweet potatoes safe, avoid storing them in the fridge. Following the easy way suggested by the online community helps protect this versatile root vegetable!
How do you properly store sweet potatoes?
To store whole sweet potatoes the right way, you need a cool, dry place. A root cellar is the best, but a pantry works if it stays around 55 degrees Fahrenheit.
Avoid putting raw sweet potatoes in the fridge because cold temperatures mess with the sweet potato tastes and create a weird white sap. The easy way to store them is loose in a basket or open container where air can move around.
Fresh sweet potatoes kept in ideal conditions can last a couple of weeks. Good sweet potatoes will feel firm with healthy sweet potato skin and no brown spots or signs of spoilage.
In the United States, storing orange sweet potatoes, purple sweet potatoes, and true yams properly means fewer spoiled sweet potatoes. Whether you’re making sweet potato fries, savory dishes, or sweet potato casserole, starting with good root vegetables is a great option for healthy eating!
How can you tell if a sweet potato has gone bad?
The easiest way to tell if a sweet potato has gone bad is by checking the skin of the sweet potato for brown spots, mold, or shriveling. A spoiled sweet potato might leak white sap or smell sour.
If you notice hollow heart, mushy areas, or black patches, it’s time to toss it. Good sweet potatoes should feel firm, like regular potatoes. Spoilage of sweet potatoes can happen faster if they aren’t stored in a dry place under the right conditions.
Fresh sweet potatoes, whether orange sweet potatoes or purple sweet potatoes, should be used within a couple of weeks. High temperatures or too much moisture can ruin your staple food fast.
Keeping whole sweet potatoes on a baking sheet in a cool spot is a good idea. Whether you’re planning sweet potato fries, savory dishes, or sweet potato casserole, using only fresh root vegetables ensures better flavor and safety!
Conclusion
So, what’s the verdict on pithy sweet potatoes? They’re safe to eat, though they might not taste as good as fresh sweet potatoes from your grocery store or vegetable garden.
When stored in ideal conditions – a cool, dry place with the right relative humidity – whole sweet potatoes can last a long time. But even with perfect storage, these versatile root vegetables eventually develop pithiness.
The white substance found in pithy areas doesn’t indicate spoilage of sweet potatoes or risk of food poisoning. It’s simply a texture change that happens naturally over time, similar to how regular potatoes develop hollow heart.
If you find affected areas in your orange sweet potatoes or purple sweet potatoes, you have options. Cutting away the pithy sections is a common way to preserve the better-tasting parts for your sweet potato recipes.
Sweet potatoes remain a staple food across the United States and North America because they’re nutritious and delicious. Their rich beta carotene content and ability to stabilize blood sugar make them a great option for many diets.
Whether you’re making sweet potato casserole, savory dishes, or crunchy sweet potato fries in your air fryer, don’t let a little pithiness discourage you from enjoying these remarkable starchy vegetables.
