a–f superscripts are significantly (p <0.05) different within column for extrusion done at 150°C. l–q are significantly (p <0.05) different within column for extrusion done at 180°C. Subscripts denote the percentage increase (↑) and decrease (↓) from control samples for corresponding properties. L^* = darkness (0) or lightness (100); a^* = redness (+); b^* = yellowness (+), redness intensity (RI = a^*/b^*), total difference of color value (ΔE).
