  1. Note: “Temp” represents temperature. L* is lightness, a* is redness, b* is yellowness, and E*ab is color difference. Data are presented as mean ± std. “*” indicates significant difference (P ≤ 0.05). “**” indicates a highly significant difference (P ≤ 0.01). 65 °C shows highly significant differences compared to other temperatures (P ≤ 0.01), while other temperatures exhibit significant differences among themselves (P ≤ 0.05). Data presented as mean ± std (n = 3).
