Zea mays Purple Corn Source & Identity
The botanical entity is Zea mays L., the maize species, which belongs to the grass family Poaceae. Purple corn is a pigmented landrace of the species, known in Peru as maiz morado, whose kernels and cob carry deep purple anthocyanins. The part used is the seed, meaning the kernel. Husk, silk and tassels are not part of this ingredient. Cob and kernel are both pigmented in the landrace, and only the kernel is used here.
Because maize is one species with many forms, the botanical name does not identify the ingredient. Yellow dent corn, sweet corn and purple corn share the binomial but differ in pigment, in starch type and in use, and the pigment of purple corn is its distinguishing property.
The color comes from anthocyanins, mainly cyanidin glycosides, which are water soluble and so move into a water extract.
