How long do peeled and cut potatoes last in the fridge?
Peeled and cut potatoes can last for about 24 hours in the fridge. However, it’s essential to store them properly to maintain their freshness and safety. Place the peeled and cut potatoes in a bowl or airtight container, cover them with cold water, and refrigerate at a temperature of 40°F (4°C) or below. Change the water every 8-12 hours to prevent bacterial growth.
It’s crucial to note that peeled and cut potatoes are more prone to spoilage than whole potatoes. This is because the cutting process exposes the potato’s flesh to oxygen, which can lead to enzymatic browning and the growth of bacteria. If you don’t plan to use the peeled and cut potatoes within 24 hours, consider freezing them to extend their shelf life.
Can I store peeled and cut potatoes in the fridge without water?
It’s not recommended to store peeled and cut potatoes in the fridge without water. When exposed to air, the cut surfaces of the potatoes will oxidize, leading to browning and the formation of off-flavors. Additionally, bacteria can multiply rapidly on the cut surfaces, increasing the risk of foodborne illness.
If you must store peeled and cut potatoes without water, make sure to cover them tightly with plastic wrap or aluminum foil to minimize exposure to oxygen. However, this method is not recommended, and it’s best to store them in cold water to maintain their freshness and safety.
