Have you ever come across a potato with those small growths called “eyes” and wondered if it’s safe to eat? Let’s delve into the topic and separate fact from fiction.
Sprouted potatoes can be a cause for concern due to the presence of compounds called glycoalkaloids, including solanine. These compounds can cause a bitter taste and, in larger quantities, can be toxic. However, the concentration of these compounds is usually low, and eating negligible amounts is unlikely to cause harm. While it’s best to remove small sprouts with a paring knife or potato peeler before using the rest of the potato, large sprouts and extensive growths should be avoided.
Key Takeaways:
- Sprouted potatoes can contain glycoalkaloids, including solanine, which may cause bitterness and toxicity in excessive amounts.
- Removing small sprouts and avoiding potatoes with large sprouts or extensive growths is advisable.
- Potatoes with dark spots can be cut out, while green potatoes should be peeled to remove the green parts.
- It’s recommended to discard severely sprouted or blighted potatoes.
- Eating small amounts of sprouted potatoes is generally safe, as glycoalkaloids are also present in other nightshade plants.
Are Sprouted Potatoes Safe to Eat?
Sprouted potatoes are generally safe to eat, although caution should be exercised. The sprouts contain glycoalkaloids, including solanine, which can be toxic in large quantities. However, the concentration of these compounds is highest in the sprouts, eyes, and bumps of the potato.

Why Do Potatoes Sprout?
Potatoes sprout due to their natural growth mechanisms. Unlike other plants and foods that require soil for growth, potatoes only need darkness and moisture. Even when stored in a dark and moist place, such as a kitchen pantry, potatoes can sprout because they have an innate belief that they are in the ground.
This growth response is a natural process of potatoes trying to grow into potato plants. Understanding the conditions that lead to sprouting can help in proper potato storage and minimizing sprouting. By controlling the factors that trigger sprouting, you can extend the shelf life of your potatoes and prevent them from going to waste.
What Causes Potatoes to Sprout?
“Potatoes have developed a unique growth response that allows them to grow into potato plants even in the absence of soil. This remarkable mechanism is driven by the presence of long-day conditions, moisture, and the natural hormones present in the potato.”
The sprouting process begins when a potato detects the right combination of environmental cues. Exposure to light, even in small amounts, can trigger the production of chlorophyll and initiate sprouting. Darkness, on the other hand, suppresses sprouting, which is why potatoes stored in well-ventilated, dark areas are less likely to sprout.
Moisture is another important factor in potato sprouting. Potatoes contain moisture, and when they sense the presence of water, they activate their growth mechanisms. This is why potatoes stored in damp environments, such as a damp paper bag or a damp cellar, are prone to sprouting.
In addition to light and moisture, hormones also play a role in potato sprouting. Potatoes naturally produce hormones such as gibberellins and auxins, which promote cell elongation and root growth. These hormones, along with other factors, create an internal biological signal that triggers sprouting.
Minimizing Sprouting Through Proper Storage
To minimize sprouting and extend the shelf life of your potatoes, follow these storage guidelines:
- Store potatoes in a cool, dark place with good ventilation.
- Avoid exposing potatoes to direct sunlight.
- Keep potatoes away from moisture, as excess dampness can promote sprouting.
- Ensure potatoes are stored in a dry environment, as excessive humidity can lead to spoilage.
- Do not store potatoes near fruits that release ethylene gas, such as bananas, as this can accelerate sprouting.
By storing potatoes in optimal conditions, you can help prevent sprouting and ensure that your potatoes stay fresh and usable for a longer period of time.
How to Prevent Potatoes from Sprouting
Although potatoes will eventually sprout, there are steps you can take to prevent or delay sprouting. By following these techniques, you can extend the shelf life of your potatoes and keep them fresh for longer.
Storing Potatoes
Proper storage plays a crucial role in preventing potato sprouting. Here’s how you can store your potatoes effectively:
- Choose a cool and dark location for storing potatoes, such as a pantry, brown bag, or cardboard box. This helps maintain an optimal temperature and reduces exposure to light.
