Solanine is a glycoalkaloid poison created by various plants in the genus Solanum, such as the potato plant. When the plant's stem, tubers, or leaves are exposed to sunlight, it stimulates the biosynthesis of solanine and other glycoalkaloids as a defense mechanism so it is not eaten.
Why are potatoes slightly toxic?
Potatoes contain two kinds of glycoalkaloids, both natural toxins, called solanine and chaconine. Exposure to light greatly increases the formation of chlorophyll and glycoalkaloids.
Can potatoes become toxic?
Most commercial varieties of potatoes are screened for solanine, but any potato will build up the toxin to dangerous levels if exposed to light or stored improperly.
How do you remove solanine from potatoes?
CONSTITUTION: Solanin is removed from potatoes by dipping the potatoes in vinegar of 30-60 deg. C, containing 0.3-1.0 vol% of acetic acid, for 2-5 minutes.
Do raw potatoes have toxins?
That's because raw potatoes contain a toxic compound called solanine, which could make you very sick. Most potatoes don't have enough solanine to kill a human, but green potatoes or any that are starting to sprout have high solanine content, which can cause symptoms including stomach pain, headache, and paralysis.
