The Ultimate Guide to Potato Storage: Keep Them Sprout-Free for Longer

When potatoes sprout, their starches transform into toxic compounds - chaconine-alpha and solanine. This is why it's so important to store potatoes properly, ensuring they remain nutritious and safe for your family's consumption.

Compared to other vegetables, potatoes are relatively easy to store. After harvesting, take the time to sort through them, removing any damaged or bruised potatoes, and then use the following storage methods to keep your potatoes fresh for longer.

1How to Store Potatoes

Store healthy potatoes in a cool, dark place

Potatoes prefer darkness and dislike moisture. Exposure to sunlight or humid conditions can cause potatoes to sprout or rot. Therefore, store them in a sunless location, such as a basement or under the kitchen cabinet.

Keep potatoes in a well-ventilated area

Avoid storing potatoes in airtight containers. Instead, use a mesh bag, a basket, or a cardboard box with circular holes punched in the sides to allow for air circulation and regulate humidity, keeping the potatoes fresher for longer.

Maintain a cool temperature

The ideal temperature for storing potatoes is between 10-15 degrees Celsius. However, this does not mean storing them in the refrigerator, as the temperature is typically around 7 degrees Celsius, which can cause potatoes to become bruised and lose their fresh flavor.

Do not store potatoes with fruits

Fruits emit ethylene gas, which can cause potatoes to sprout prematurely and even become toxic. So, if you want to extend the shelf life of your potatoes, avoid storing them with fruits.

Regularly inspect potatoes for signs of deterioration

It is advisable to periodically check your potatoes. If you notice any signs of deterioration, remove the affected potatoes to prevent the issue from spreading to the other tubers.

2Signs That a Potato Needs to Be Discarded

Green Skin: If you notice a potato with a soft, slightly wilted texture and a green skin, it is best to discard it or, if you must cook it, remove the green portion before consumption.

Sprouted Potatoes: Potatoes that have sprouted can produce toxins. Therefore, if you see any sprouts, it is advisable to discard the potato rather than risk potential health issues.

Decayed Potatoes: If the potato flesh becomes soft and mushy, and there is an unpleasant odor, discard it immediately.

Notes on Potato Storage

Avoid washing potatoes before storing them, as moisture can lead to decay. The drier the potatoes are, the longer they will last. If you want to remove dirt or debris from the surface, use a dry cloth or brush to gently clean them.

While it is not advisable to store potatoes in the refrigerator, if you have already done so, bring them to room temperature before cooking.

If you cut potatoes and cannot cook them immediately, soak them in cold water, and they will stay fresh for up to a day.

By following these storage tips, you can not only extend the shelf life of your potatoes but also maintain their nutritional value and delicious flavor.

Frequently asked questions

To store potatoes and prevent sprouting, keep them in a cool, dark, and dry place, ideally in a paper bag or mesh bag. Avoid storing potatoes in the fridge, as the cold temperature can convert their starch into sugar, affecting their taste and texture. Ensure good air circulation and avoid stacking potatoes to prevent moisture buildup, which can lead to sprouting and rot.

Green discoloration on potatoes indicates the presence of solanine, a toxic compound. To avoid this, keep potatoes away from direct sunlight. Store them in a dark place, like a pantry or a box, and consider using a paper bag or mesh bag to allow some light to pass through while still providing sufficient darkness.

Yes, freezing is a great way to extend the shelf life of potatoes. Cut them into the desired shape, blanch them, and then freeze them in airtight containers or freezer bags. Frozen potatoes can last for several months and are perfect for frying, roasting, or mashing.

To prevent cut potatoes from turning brown, submerge them in cold water immediately after cutting. The water creates a barrier against oxygen and slows down the browning process. You can also add a bit of lemon juice or vinegar to the water for extra protection.

Yes, there are a few signs to watch for. If a potato has started to sprout, has wrinkled skin, or shows signs of mold or rot, it’s best to discard it. Additionally, if the potato has turned green, especially in bright light, it indicates the presence of solanine, and it’s best to peel or discard it.
