Cochineal is a dye Made from dried and ground female bodies of the scale insect and cochineal extract is the concentrated solution obtained after removing the alcohol from an aqueous-alcoholic extract of cochineal. Carmine is the aluminum or calciumaluminum lake formed by precipitating carminic acid onto an aluminium hydroxide substrate using aluminum or calcium cation as the precipitant. The carminic acid used to make the lake is obtained by an aqueous extraction of cochineal.
