How do you reduce solanine in potatoes?

Alkaloids like solanine have been shown to start decomposing and degrading at approximately 170 °C (338 °F), and deep-frying potatoes at 210 °C (410 °F) for 10 minutes causes a loss of ∼40% of the solanine. However, microwaving potatoes only reduces the alkaloid content by 15%.

How do you make green potatoes safe?

You can prevent potatoes from turning green by storing them in a cool, dark area with good air circulation and high humidity. The ideal environment for storing potato tubers for long periods is 45 to 50 F with 90 to 95 percent relative humidity and darkness.

What foods contain glycoalkaloids?

Glycoalkaloids are a group of nitrogen-containing compounds that are naturally produced in various cultivated and ornamental plant species of the Solanaceae family. This large family of plants includes commonly consumed vegetables such as potatoes, tomatoes, eggplants, and peppers.

Are sprouted potatoes toxic?

Sprouted potatoes contain higher levels of glycoalkaloids, which can be toxic to humans when eaten in excess. Health problems linked to eating sprouted potatoes range from stomach upset to heart and nervous system problems, and, in severe cases, even death. They may also increase the risk of birth defects.
