Solanine is an alkaloid found in plants of the nightshade family (Solanaceae), specifically tomatoes, eggplant, and most significantly, potatoes.
Which potatoes have more solanine?
Solanine levels are highest in the skin of a potato. For this reason, peeling a green potato will help significantly reduce its levels. Studies have estimated that peeling a potato at home removes at least 30% of its toxic plant compounds. However, that still leaves up to 70% of the compounds in the flesh ( 4 ).
Do all potatoes contain solanine?
Solanine is naturally present in all potatoes, generally in the upper one-eighth of the skin. It is a colorless alkaloid with a bitter taste. Usually, a person will not keep eating a bitter potato because of the taste.
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.
Which potatoes are toxic?
You're better off tossing potatoes that have turned green or grown sprouts. Eating them puts you at risk for potential toxicity from solanine and chaconine, two natural toxins found in green or sprouted potatoes.
