Glycoalkaloids occur naturally in potatoes and are toxic to humans at high levels. Glycoalkaloids are concentrated in the peel and prolonged exposure of tubers to light will stimulate the formation of glycoalkaloids near the surface of the potato tuber. Glycoalkaloids are not broken down by cooking or frying.
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.
How do you get rid of glycoalkaloids?
Store potatoes in a cool, dry, dark environment to minimize glycoalkaloid formation. Cut away any parts of a potato that show signs of greening, physical damage (cuts or bruises), rotting, or sprouting. In severe cases, discard the entire potato. Peel the skin from potatoes to reduce glycoalkaloid levels.
How does solanine affect the body?
Solanine poisoning is primarily displayed by gastrointestinal and neurological disorders. Symptoms include nausea, diarrhea, vomiting, stomach cramps, burning of the throat, cardiac dysrhythmia, nightmares, headache, dizziness, itching, eczema, thyroid problems, and inflammation and pain in the joints.
Does potato starch contain glycoalkaloids?
Potatoes are a source of glycoalkaloids (GAs) represented primarily by alpha-solanine and alpha-chaconine (about 95%). Content of GAs in tubers is usually 10-100 mg/kg and maximum levels do not exceed 200 mg/kg. GAs can be hazardous for human health.
