Tips: Discard potatoes that are too soft, slimy, or excessively wrinkled.
4. Strong, Offensive Odor
Meaning: A foul odor from raw potatoes suggests spoilage or the production of harmful compounds.
Tips: Trust your sense of smell: if the smell is unpleasant, discard it.
5. Bitter Taste
Meaning: Solanine and chaconine impart a bitter taste to potatoes. If your cooked potatoes have an abnormally bitter taste, it could indicate a high concentration of toxins.
Tips: Stop consuming immediately and discard the dish.
How to prevent potatoes from becoming toxic?
1. Proper Storage
Store potatoes in a cool, dark, and well-ventilated place (ideally between 7 and 13°C). Avoid direct sunlight, which stimulates the production of chlorophyll and solanine.
Do not store potatoes in the refrigerator, as the cold can convert starch to sugars, altering the taste and texture.
2. Inspect before use
Always check potatoes before cooking for green spots, sprouts, or signs of spoilage. Trim away any suspect areas generously.
3. Cook thoroughly
Cooking slightly reduces the concentration of solanine, but does not eliminate it completely. Never rely on cooking alone to make unsafe potatoes edible.
4. Use fresh potatoes
Older potatoes are more likely to develop sprouts or green spots. For optimal quality and safety, try to consume them within a few weeks of purchase.
What happens if you eat toxic potatoes?
Eating potatoes high in solanine can lead to solanine poisoning, which typically causes mild to moderate symptoms such as:
Nausea and vomiting
Diarrhea or stomach cramps
Headache or dizziness
Fatigue or confusion
In rare, extreme cases (usually in large amounts), solanine poisoning can lead to more serious effects such as fever, hallucinations, or seizures. However, most people experience only mild discomfort if they accidentally ingest small amounts of solanine.
Conclusion
With proper storage and careful inspection, the risk of consuming toxic potatoes is minimal. By learning to identify green spots, sprouts, and other warning signs, you can safely enjoy this versatile vegetable. Remember: when in doubt, always err on the side of caution and throw out any questionable potatoes. After all, your health is worth more than a potato!
