3.2. Colour of WGP and WGP fortified yogurt and salad dressings L⁄ , Hue and Chroma values of freeze dried WGP and its fortified products are presented in Table 3. The control yogurt sample without the addition of WGP received the highest L⁄ of 92.18, but the lowest Hue value of 1.26. As expected, the lightness and Hue values decreased, but the Chroma increased along with increased amount of WP added, but no significant difference (P < 0.05) between 2% WP and 3% WP (w/w yogurt) samples. Overall, LE-Y and FDF-Y samples obtained the higher (P < 0.05) L⁄ and Hue values, but lower Chroma value than those of 2% WP (w/w yogurt)
