Comparison of Beta-cryptoxanthin Bioavailability From Biofortified Maize in Humans

Completed · Not applicable

Conditions studied: β-cryptoxanthin Bioavailability From Biofortified Maize in Humans

In brief

The purpose of this study is to determine how well the body absorbs the carotenoid beta-cryptoxanthin (BCX) from a type of corn that has been naturally bred (not genetically engineered) to contain higher amounts of BCX than traditional breeds of corn. Because this new type of corn contains higher amounts of BCX, it appears more orange in color than traditional types of corn. Understanding how well the body can absorb the BCX from the corn may help companies develop food products that may have improved nutritional quality.
