Why Do Sweet Potatoes Go Bad?
Sweet potatoes go bad due to their high water content, making them perishable. When you store them in a warm room, it speeds up the rotting process. To prevent this, buy the freshest sweet potatoes possible and keep them away from heat or moisture. Whole and untouched sweet potatoes last longer than peeled or cooked ones, so consider factors like cooking, baking, and reheating when dealing with their shelf life. Also, be aware of ethylene gas, which can further promote spoilage, by keeping them away from other ethylene-producing fruits and vegetables
How To Tell if a Sweet Potato is Bad
To identify a bad sweet potato, keep an eye out for the following signs:
- Softening or squishiness: This results from the high water content, and as sweet potatoes age, they will become softer.
- Dark spots or discoloration: Brown and black spots on the skin indicate spoilage.
- Sprouting: Sprouts on a sweet potato are signs of it being past its prime, and it’s best to avoid eating it to prevent illness.
- Mold: Mold on the surface is a clear indication of spoilage. If mold is present, do not eat the sweet potato.
Always remember to prioritize your health. If you have any doubts about the freshness of a sweet potato, it’s better to throw it away than risk getting sick. When assessing cooked sweet potatoes, be watchful for molds – discard them immediately if mold is present. Avoid eating old or bad sweet potatoes to prevent food poisoning and other health risks. To choose good sweet potatoes, look for ones without black spots, weird growths, or signs of spoilage. Lastly, enjoy your fresh, delicious, and healthy sweet potatoes!
How to Store Sweet Potatoes
To properly store sweet potatoes and prolong their shelf life, follow these storage tips:
- Choose the right location: Store sweet potatoes in a cool, dark place, preferably a pantry. Ensure that sunlight and moisture cannot reach them, as both can cause spoilage more quickly.
- Create the right environment: Make sure your pantry is dry and dark to ensure the best storage conditions for your sweet potatoes.
- Shelf life: When stored correctly, sweet potatoes can last for a month or two before they begin to go bad.
It’s important to note that storing sweet potatoes in the refrigerator is not recommended. Although they should be kept in a cool area, the fridge is too cold and can lead to hardness and moisture-related issues.
Once you’ve cooked your sweet potatoes, however, any leftovers should be stored in the refrigerator. This is because leaving cooked sweet potatoes at room temperature can cause bacteria buildup, increasing the risk of illness. By storing them properly in the fridge, your cooked sweet potatoes can last for about five days.
Can You Freeze Sweet Potatoes?
Yes, you can absolutely freeze sweet potatoes to prolong their shelf life! Frozen sweet potatoes can be either cooked or uncooked, but cooked ones tend to last longer. To freeze them, simply place the sweet potatoes in a freezer bag or an airtight container.
These frozen sweet potatoes can last in your freezer for up to 12 months. Make sure to thoroughly defrost them before cooking and serving, especially for your kids. Keep in mind that the texture might become slightly mushy after thawing, so they might be better suited for a sweet potato pie rather than roasted sweet potatoes. To get creative with your thawed sweet potatoes, consider trying an instant pot sweet potato recipe as well.
Sweet potatoes offer a variety of health benefits, such as being rich in fiber, iron, vitamins, and minerals. They provide antioxidants, aid in digestion, and help regulate blood sugar levels. Enjoy their versatility while maintaining freshness and safety.
