Diversity of the Peruvian Andean maize ( L.) race : Polyphenols, carotenoids, antioxidant capacity, and physical characteristics.

The high diversity of the Peruvian Andean maize ( L.) represents a biological and genetic heritage relevant for food security, but few studies are targeted toward its characterization and consequent valorization and preservation. The objective of this study was to evaluate the potential of the Peruvian Andean maize race with respect to its bioactive profiles (free and bound phenolic and carotenoid composition), physical characteristics, and antioxidant properties.
