However, when potato tubers turn green there is usually an increase in a glycoalkoloid compound called solanine. Consequently, it is important to store potatoes in the absence of light to prevent greening. Tubers with a high concentration of solanine will taste bitter, and can be harmful if eaten in large quantities.
