Raw sweet potatoes can generally be left at room temperature for up to 3–5 days. If you plan to keep them longer than that, it’s best to refrigerate them at 40°F or lower. The starches in sweet potatoes will break down over time, leading to tougher and dryer potatoes that are not ideal for eating.
Additionally, leaving sweet potatoes out unrefrigerated for too long can also cause them to spoil, leading to a sour smell and dark spots and streaks on their skin. If you notice any signs of spoilage, it’s best to throw them out.
Do uncooked sweet potatoes need to be refrigerated?

Ideally, they should be stored in a pantry, where they remain untouched by extremes of temperature and can be quickly served. However, if the environment is too humid, it may be best to store them in the refrigerator, where they are surrounded by cool air.
Stored in this way, sweet potatoes can last between two to three weeks.
How can you tell if sweet potatoes have gone bad?

If you’ve purchased sweet potatoes from a store and plan to use them within a few days, you can leave them unwashed until you are ready to cook with them.
Washing sweet potatoes before storing them can cause them to spoil faster due to the introduction of moisture. If you plan to store the sweet potatoes for more than a week, it is a good idea to at least rub off any dirt that may be on the skins.

After blanching, allow the sweet potatoes to cool completely before placing them in an air-tight container or bag and storing in the freezer. Stored properly, frozen raw sweet potatoes can last up to 6 months.
When ready to use, either thaw the sweet potatoes in the fridge overnight or cook them without thawing.

Potatoes that are exposed to light will turn green and may become bitter in taste, so it is best to store them in a place that is away from any sources of light, such as in a paper bag or cardboard box.
When selecting potatoes, choose those that are firm and unwrinkled in texture. When storing them, make sure that they are not touching each other, as this can cause them to spoil more quickly.

This helps prevent moisture from reaching the potatoes and encourages them to last longer.
Is it safe to eat sweet potatoes with black spots?

Overall, it’s best to be cautious when consuming sweet potatoes with black spots. If the spots seem suspicious or signs of spoilage are present, it’s best to discard the sweet potato to avoid any potential illness.
Why do sweet potatoes go black when peeled?
When sweet potatoes are peeled, they may turn black due to a process known as “enzymatic browning”. This occurs when enzymes within the sweet potato come into contact with oxygen in the air, causing a reaction that results in the discoloration.
Enzymatic browning also causes other fruits and vegetables to darken as well. To avoid this, sweet potatoes can be peeled just prior to cooking and can also be treated with an antioxidant such as lemon juice or citric acid solution to reduce the time it takes for the enzymatic reaction to occur.
Additionally, it is best to store sweet potatoes in a cool, dry place and to not leave them sitting out for too long, which can also cause the potato to discolour.
Should I refrigerate my sweet potatoes?
Yes, you should refrigerate your sweet potatoes. Sweet potatoes can last up to three weeks when kept in a cool and dry area, but if you want them to last longer, storing them in the refrigerator is the best way to ensure they stay fresh.
To refrigerate your sweet potatoes, make sure they are completely cool before you put them in the refrigerator. Place your sweet potatoes in an airtight container or plastic bag with holes for ventilation.
Keep them away from any other fruits and vegetables, as the ethylene gas produced by the potatoes can cause other produce to spoil quickly. Be sure to check the potatoes often and if you spot any mold or signs of spoilage, discard the potatoes immediately.
What kind of container should I store potatoes in?
When it comes to storing potatoes, the right container can make all the difference. Potatoes should always be kept in a cool, dark place, away from sunlight, temperatures over 45 degrees Fahrenheit, and humidity levels over 95%.
The best containers to store potatoes in are those that are made out of a breathable material, like jute or fabric, which will allow airflow. It’s important to keep the potatoes at a consistent temperature, so the most suitable containers are those that are densely woven, non-toxic, and not made from any type of cardboard or plastic.
The lid or top of the bag should also be vented to allow for proper air flow. Finally, the potatoes should be inspected every few weeks, and any signs of sprouting should be removed immediately.
