ifferent areas of the surface of five different slices. Color coordinates
for bleached tomato pomace were also measured to examine its effect
on the color of studied products. The L*, a* (±red − green) and b*
(±yellow − blue) color coordinates were determined according to
the ISO/CIE standard color space system proposed by Commission
Internationale de l'Eclairage (Joint ISO/CIE Standard, 2008). In addition,
hue-angle (h°) and the saturation index or chroma (C*), which
describes the hue and brightness or vividness of color, respectively,
were calculated using the following Eqs. (3) and (4):
