Purple Corn Extract

Purple corn (Zea mays) is the same species as the white and yellow corn common to the U.S. It is a native crop in the Peruvian Andes, and it gains its deep purple color from its rich content of phenolic compounds, including the dark-red and purple-colored anthocyanins. The extract is made from the cob, which is boiled to extract the active components in liquid form. The liquid is then concentrated, dried, and standardized for anthocyanin content.
