How Long Can You Store Sweet Potatoes?

How Do You Know When Sweet Potatoes Go Bad?

  • Green Spots and Shoots: Sweet potatoes do not stay completely dormant after harvesting, and they often produce small sprouts known as eyes. This is especially true with organically grown or farm-stand potatoes, as many mass-produced retail potatoes are treated with a chemical that suppresses sprouting. Remove the small sprouts before boiling the potato if it otherwise looks and smells fresh. Long-sprouting potatoes should be avoided, as should those with other signs of aging. Green specks occur just before sprouts form. Small spots should be clipped away, but large patches of green should be removed, due to the moderate toxicity of these spots.
  • Spoilage smell: Fresh sweet potatoes have an earthy, starchy odor. As they degrade, the aroma changes, becoming harsh and rotten. Sweet potatoes may appear fine on the outside, but they are rotten on the inside. If you see a sweet potato that appears to be fine but smells wrong in the grocery store, don’t buy it. If this happens at home, simply cut the potato open to see if the spoiled section is small enough to remove and discard, or if the entire potato must be thrown away. If there are no black stains, one blemished place does not entail throwing the entire potato; it is quite acceptable to consume the undamaged section. Simply split the sweet potato into tiny pieces to inspect the interior for the first symptoms of deterioration.
  • Aging Signs: In the same manner that human skin ages, sags, and develops spots, sweet potato skin ages, sags, and develops spots. While they are signs of a happy life in people, they are warning signs in the case of bad sweet potatoes. Although a little age won’t spoil the taste of sweet potatoes, any with wrinkled, sagging skin or a mushy feel, or if they’re damp in the bag, should be tossed out.

How Long Do Sweet Potatoes Last At Room Temperature?

Whole, uncooked potatoes can last for 2-3 weeks at room temperature. They can last up to a month if the temperature is lower than the room temperature. You’ll have to settle for room temperature unless you have an unheated cellar. Store them loosely covered in a paper bag, mesh bag, or cardboard box to keep them fresh. Potatoes can be stored for up to two weeks at room temperature.

How Long Do Sweet Potatoes Last In The Fridge?

While we’ve already established that keeping potatoes in the fridge isn’t ideal, there are times when you don’t have a choice. Due to a shortage of cupboard space or hot/humid conditions, you may wish to keep your potatoes in the refrigerator. If you choose to keep your potatoes in the fridge for any reason, they will last three to four weeks. They will develop a sweet flavor when cooked.

Can You Freeze Sweet Potatoes?

Yes, you can freeze sweet potatoes, and you should do so if you have a lot of them. One thing to keep in mind is that, because raw sweet potatoes contain a lot of water, you should only freeze cooked or partially cooked sweet potatoes. When the water freezes, the sweet potatoes become mushy and gritty when they are thawed. Cut raw sweet potatoes should be kept chilled in a dish of cold water. They will last another 24 hours. Finally, cooked potatoes, as well as any leftovers, will keep in the fridge for three to four days.

How To Freeze Sweet Potatoes?

  • Peel: Although this step is optional, it is highly recommended because blanching is most effective when the skin is removed. If you plan to mash your potatoes after they’ve thawed, it’s a good idea to cube them now.
  • Blanching: Half-fill a kettle with water and salt it. In a large pot over high heat, bring the water to a boil. After the water has come to a boil, add the potatoes. Once the water is boiling, add the potatoes. The time it takes to blanch potatoes or potato pieces varies depending on their size, ranging from three minutes for baby potatoes or little cubes to 10 minutes for large russets. Remove the potatoes from the boiling water and swiftly plunge them into an ice bath to stop the cooking process.
  • Drain the potatoes in a colander after they have completely cooled. When they’ve drained, lay them out in a single layer on a kitchen towel. Paper towels can be used to absorb excess moisture.
  • To flash freeze the potatoes, arrange them in a single layer on a parchment-lined cookie sheet. Freeze for at least 6 to 12 hours, or overnight in the freezer.
  • Freeze: Once the potatoes are frozen, place them in freezer-safe storage containers and label them with the date.

How Long Does It Take To Freeze Sweet Potatoes?

It takes at least 6 to 12 hours to freeze sweet potatoes in the freezer.

How Long Do Sweet Potatoes Last In The Freezer?

Cooked sweet potatoes freeze well, but raw sweet potatoes do not, so it is recommended to cook them before freezing. If cooked potatoes are placed in a freezer-safe bag or airtight container, they will last 10 to 12 months in the freezer.

How Long Do Sweet Potatoes Last In Cold Storage?

Sweet potatoes can be kept in cold storage for up to 8 months. Sweet potatoes are chilled by lowering the temperature by 0.5°C per day. Seed potatoes should be maintained at 2-4°C in the refrigerator, while other types should be kept at 4-10°C. Controlling carbon dioxide, on the other hand, is just as critical in cold storage as controlling cold room temperature and humidity. The amount of carbon dioxide in the atmosphere should be kept under control and within a specified range.

Best Way To Store Sweet Potatoes?

Raw sweet potatoes should be kept in a cool, dark, and relatively dry environment while not in use. This will prevent them from sprouting for as long as possible, as well as inhibit mold growth. Refrigerating or freezing raw potatoes is not a good idea. Browning, softening, and a rise in the sugar content of the potatoes might all result from this.
