What is Solanine

Solanine is a poisonous substance naturally occurring in potatoes and other members of the nightshade family, like tomatoes and eggplants. Solanine can be toxic even in small amounts, and in very large doses, it can also be fatal.

The Solanine poison is found throughout the potato plant, especially in green potatoes and the new sprouts. Potatoes produce small amounts of solanine as a natural defense against insects, disease and predators. But as the levels increase with prolonged exposure to light and warm or cold temperatures, it turns the potatoes green and makes them poisonous for consumption. This green color is actually the result of increased levels of chlorophyll, which by itself is harmless. But it is also a sign of increased solanine in the tuber, as it is produced at the same time as chlorophyll.

Symptoms of Potato Poisoning

Although potato poisoning is rare, it does happen from time to time. There are few reports of poisoning because of eating green potatoes or drinking potato leaf tea. Mentioned below are signs and symptoms of potato poisoning that can turn fatal in large doses:

  • Delirium (sudden severe confusion and rapid changes in brain function).
  • Diarrhea
  • Dilated pupils
  • Fever
  • Hallucinations
  • Headache
  • Loss of sensation
  • Lower than normal body temperature (hypothermia)
  • Paralysis
  • Shock
  • Slow pulse
  • Slowed breathing
  • Stomach or abdominal pain
  • Vision changes
  • Vomiting

How to Prevent Solanine Poisoning

Exposing the potatoes to light, especially the fluorescent light triggers the production of solanine. This can also happen in very cold or warm temperatures. So it is always best to store them in cool, dim, or dark place, preferably between 50°F and 65°F. If they must be stored in a lighted place, they can be kept in a brown paper bag which is loosely closed for air circulation.

So remember:

  • Not to eat potatoes that are spoiled or green below the skin.
  • Potatoes that are not green and have had any sprouts removed are safe to eat.
  • If the taste of a potato is found to be bitter, then it is better not to consume it.
