How long can sweet potatoes last out of the fridge?
Sweet potatoes can last for several weeks to a few months when stored properly out of the fridge. The exact duration depends on various factors, including the variety, maturity, and storage conditions. Generally, sweet potatoes can be stored at room temperature for about 2-4 weeks. However, if you store them in a cooler, darker place with good ventilation, they can last for 2-3 months.
It’s essential to check on the sweet potatoes regularly for any signs of spoilage, such as soft spots, mold, or a sour smell. If you notice any of these signs, it’s best to use the sweet potatoes immediately or discard them. Proper storage and handling can help extend the shelf life of sweet potatoes, making them a convenient and nutritious addition to your meals.
What is the ideal storage condition for sweet potatoes?
The ideal storage condition for sweet potatoes is a cool, dark place with good ventilation. The temperature should be between 55°F and 60°F (13°C and 15°C), and the humidity level should be around 80-90%. This environment helps to slow down the respiration process, which can cause the sweet potatoes to spoil faster. You can store sweet potatoes in a paper bag, breathable container, or a root cellar to maintain the optimal storage conditions.
Avoid storing sweet potatoes in direct sunlight, near a heat source, or in a humid environment, as these conditions can cause them to spoil quickly.
