Total color density (TCD) was expressed as total absorbance values of the brown compounds, which show maximum absorbance at 420 nm and absorbance of juice that gives its maximum at 533 nm (Alper, Bahçeci, & Acar, 2005). The pomegranate juices were diluted with distilled water for each test in order to obtain an absorbance below 1.0 measured at 533 nm. TCD was estimated by Eq. (1), where DF was the dilution factor.
