Superficial color was measured for all strawberries samples, employing the parameter of CIRG = (180 − h)/(C + L) (Carreno˜ et al., 1995) with a Minolta CR-410 colorimeter, using the CIELAB color system. L is the lightness and corresponds to a black–white scale, h is the hue angle on the color wheel, and C is the chroma, a measure of the intensity of color.
