What Happens When Potatoes Sprout?

When a potato begins to sprout, it is essentially transitioning into a new growth phase. This process involves the potato using its stored nutrients to produce new shoots, which are the sprouts you see. The presence of sprouts indicates that the potato has been exposed to certain conditions like light or warmth, which trigger this natural growth process.

• Chemical Changes: As a potato sprouts, certain chemical compounds, such as solanine and chaconine, may increase. These are naturally occurring toxins that can be harmful when consumed in large quantities.
• Visible Changes: You will typically notice small, greenish-white shoots emerging from the potato, along with potential changes like a green tint on the skin.

Can You Eat Sprouting Potatoes?

Eating sprouting potatoes can be a gray area and largely depends on the extent of the sprouting. If only small sprouts are present and the potato remains firm, it is generally safe to consume after removing the sprouts and any green spots.

• When It’s Unsafe: If the potato is shriveled, soft, or heavily sprouted, it indicates significant solanine levels, making it unsafe to eat. Solanine is toxic and can cause symptoms like nausea, headaches, and digestive issues.

Ensure safety by:
– Walking through any potato with visible sprouts and discarding those with large growths.
– Thoroughly cooking the potatoes, as heat can help reduce solanine levels.

Nutritional Impact of Sprouting

The nutritional content of potatoes begins to change once they start sprouting. Here’s how:

• Loss of Nutrients: As potatoes sprout, they deplete stored nutrients, leading to lower caloric and vitamin content.
• Increase in Sugars: The sprouting process converts starches into sugars, thereby altering the taste and potentially boosting calorie content.

How to Safe-proof Your Potatoes?

Preventing potatoes from sprouting can help maintain their edibility and nutritional value. Here are some effective tips:

• Proper Storage: Store potatoes in a cool, dark, and well-ventilated place, ideally at temperatures between 45 and 50°F (7 to 10°C).
• Avoid Light Exposure: Light can trigger sprouting and greening, so consider using breathable paper bags or burlap sacks.
• Use After Purchase: Try to consume potatoes within a few weeks of purchase to prevent sprouting.
• Natural Inhibitors: Place an apple with your potatoes to help slow down sprouting due to ethylene gas production.

Environmental and Health Considerations

Beyond personal consumption, managing sprouting potatoes involves broader considerations.

• Environmental Impact: Discarding potatoes unnecessarily contributes to food waste, which has environmental repercussions.
• Health Awareness: Public awareness of the risks of consuming sprouted potatoes can help reduce health issues associated with solanine poisoning.

Organizations like World Health Organization offer valuable resources on food safety and minimizing waste.

FAQ

1. Are sprouted potatoes poisonous?
Sprouted potatoes can contain high levels of solanine, which can be toxic. It’s best to remove sprouts and green areas before consumption and avoid eating if the potato is soft or shriveled.

2. Can eating sprouted potatoes make you sick?
Yes, consuming sprouted potatoes, especially in large quantities, can lead to solanine poisoning causing symptoms like nausea and headaches.

3. How many times can I cut off sprouts before the potato is unsafe?
It’s generally safe to cut off small sprouts a couple of times, but if sprouting persists and the potato becomes soft, it’s best to discard it.

4. Do sweet potatoes sprout the same as regular potatoes?
Yes, sweet potatoes can also sprout when stored improperly, though they contain different compounds than regular potatoes.

5. Should I throw away green potatoes?
Yes, green potatoes likely have high levels of solanine and should be discarded to avoid toxicity issues.
