However, for peeled sweet potatoes, refrigeration becomes a more critical component of storage.
The Process of Storing Peeled Sweet Potatoes in the Fridge
If you decide to peel your sweet potatoes before storing them in the fridge, there are several steps you can follow to maximize their shelf life.
First, after peeling, make sure to remove any eyes or soft spots, as these areas can quickly become infected with bacteria. Next, submerge the peeled sweet potatoes in cold water to prevent them from turning brown due to oxidation. You can add a bit of lemon juice or vinegar to the water to further prevent browning.
After this step, pat the sweet potatoes dry with a paper towel to remove excess moisture. This is crucial because moisture can lead to mold and bacterial growth.
Finally, wrap the sweet potatoes tightly in plastic wrap or aluminum foil and store them in the refrigerator. Make sure they are kept away from strong-smelling foods, as sweet potatoes can absorb odors easily.
Considerations for Storing Peeled Sweet Potatoes
When storing peeled sweet potatoes in the fridge, it’s essential to consider a few key factors. The storage life of peeled sweet potatoes is generally shorter than that of whole, unpeeled sweet potatoes. They can typically last for a few days to a week when stored properly in the refrigerator.
Another consideration is food safety. Peeled sweet potatoes are more prone to contamination. Always check for signs of spoilage before consumption, such as mold, sliminess, or an off smell.
Tips for Extending Shelf Life
To extend the shelf life of your peeled and refrigerated sweet potatoes, consider the following:
- Store them at a consistent refrigerator temperature below 40°F (4°C).
- Minimize exposure to air by sealing them properly.
- Keep them away from direct contact with moisture.
