How to Store Potatoes to Prevent Them from Turning Green

Definition: Storing potatoes properly is essential to prevent them from turning green. When potatoes are exposed to light, they produce chlorophyll, which causes them to turn green. This green color indicates the presence of solanine, a toxic compound that can make potatoes taste bitter and potentially harmful if consumed in large quantities.

Why Do Potatoes Turn Green?

Potatoes turn green due to the presence of light. When potatoes are exposed to light, they undergo a process called phototropism, where they start producing chlorophyll to aid in photosynthesis. The chlorophyll gives the potatoes a green color, indicating that they have started to produce solanine.

How to Store Potatoes Properly

Follow these steps to store potatoes correctly and prevent them from turning green:

Choose the right storage location: Find a cool, dark, and well-ventilated area to store your potatoes. A temperature range of 45-50°F (7-10°C) is ideal for long-term storage.

Avoid exposure to light: Potatoes should be stored in a completely dark environment. Light can penetrate through thin plastic bags or containers, so it’s best to store them in a paper bag or a breathable container that blocks out light.

Keep them dry: Moisture can cause potatoes to rot quickly. Make sure the storage area is dry and free from any dampness. Avoid washing potatoes before storing them, as moisture can promote sprouting and spoilage.

Inspect regularly: Check your stored potatoes regularly for any signs of sprouting, rot, or green coloration. Remove any damaged or green potatoes to prevent the spread of solanine to the rest of the batch.

Additional Tips

Here are some additional tips to help you store potatoes effectively:

• Avoid storing potatoes near onions: Onions release gases that can cause potatoes to spoil quickly. Keep them separate to prevent premature spoilage.
• Do not refrigerate: Potatoes should not be stored in the refrigerator, as the cold temperature can convert the potato starches into sugars, resulting in a sweeter taste and a darker color when cooked.
• Use within a reasonable time: Even when stored properly, potatoes will eventually start to sprout or lose their quality. It’s best to use them within a few months of storage.
