Integrated metabolite analysis and health-relevant functionality of white, red, and orange maize ( L.) from the Peruvian Andean race at different maturity stages.

The high maize () diversity in Peru has been recognized worldwide, but the investigation focused on its integral health-relevant and bioactive characterization is limited. Therefore, this research aimed at studying the variability of the primary and the secondary (free and dietary fiber-bound phenolic, and carotenoid compounds) metabolites of three maize types (white, red, and orange) from the Peruvian Andean race at different maturity stages (milk-S1, dough-S2, and mature-S3) using targeted and untargeted methods. In addition, their antioxidant potential, and α-amylase and α-glucosidase inhibitory activities relevant for hyperglycemia management were investigated using models.

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.
