Different studies have found highly significant correlation between carotenoid content and color parameters in different food samples ( Onwude et al., 2017 ; Arias et al., 2002 ; Melendez-Martinez et al., 2003 ; Andreu-Sevilla et al., 2008 ; Ruiz et al., 2008 ; Itle and Kabelka, 2009 ; Amenya and Wilson, 1997 ) suggesting that use of color parameters could be useful in estimating carotenoid content in maize grains especially in resource poor settings targeted for biofortification.

Total color change (Δ<i>E∗)</i> is a poor estimator of total carotenoids lost during post-harvest storage of biofortified maize grains.
