How to Store Potatoes

Preservation Technique

So you can best how to store potatoes while still ensuring their quality. After buying or harvesting potatoes, take a few minutes to sift through them. Discard tubers that are peeled, bruised, or show any signs of damage. These bulbs need to be used early as they will spoil faster than regular bulbs and can damage other normal potatoes.

Potatoes should be stored in a dry and dark place (e.g. basement, under kitchen cabinets), away from light and moisture – conditions that can cause potatoes to sprout or rot.

You also need to let the potatoes air out. Most supermarkets pack potatoes in mesh bags, which is a great way to preserve them, so don’t be fooled into transferring the potatoes to another sealed bag. If the potatoes you buy do not come in mesh bags, you can put them in a vented box, and a newspaper should be placed between the layers of potatoes. Then cover the box with a newspaper.

Potatoes should be kept cool. The best temperature to store potatoes is below 10 degrees Celsius (6-10 degrees Celsius). At this temperature, potatoes can stay fresh for several months if stored properly. At a temperature of 10-15 degrees Celsius, stored in a dark, dry and airy place, potatoes remain delicious for 2 weeks to a month. Keep in mind that the refrigerator is often too cold to store potatoes and can damage the taste and color of the potatoes (causing the starch in the potato to turn into sugar, making it taste too sweet and turning dark when cooked). up).

During storage, potatoes should be checked weekly for signs of spoilage, because one spoiled potato can infect other potatoes, so you need to remove it soon.

Take Notes to Store Potatoes

Do not wash potatoes before storing: because washing with water can easily damage potatoes. Keep the potatoes as dry as possible. If the potato has a lot of sandy soil, wait for the soil to dry and then use a toothbrush to gently scrub away the soil. You should only wash it before taking it out for processing.

If storing potatoes in the fridge, warm them to room temperature before cooking.

If the potato has been cut, it should be cooked as soon as possible. If it cannot be cooked immediately, you can put the potato in cold water. This way you can preserve the potato for 2-3 days.

Do not put potatoes near the fruit. Many fruits like apples, pears, and bananas release a chemical called ethylene. This gas encourages fruit ripening (you may notice that fruits tend to ripen faster when you keep them side by side) causing the potatoes to sprout early.

However, if you are going to save the potatoes to make french fries, you can preliminarily prepare them: wash them, cut them into small pieces, boil them with a little salt, and put them in a pot of water right from the start. When the pot of water is just boiling, pour the potatoes into the basket to drain, then store them in a box, put in the freezer compartment of the refrigerator. Defrost the potatoes for about 10 minutes before frying, and you will have crisp, crispy fries.
