Before the 1900s eggplant consumption was thought to cause insanity and was called the “mad apple,” by Europeans.
High society ladies of China used eggplant skins to make black dye and stained their teeth for fashionable cosmetic use.
The color found in eggplant skin, results from anthocyanin, a water-soluble falvonoid pigment. This pigment also creates the red, blue, and purple coloring in other vegetables, fruits, and flowers.
