Statistical analysis was performed using the SAS statistical software. Meanwhile, the analysis
of variance (ANOVA) was used to compare the mean values of the sample hues at different
treatment factors (treatment days and temperature). Then, the mean comparison test using
Least Significant Difference (LSD) was conducted to compare the treatment group means after
the ANOVA results had been shown to be significant. Finally, a correlation analysis between
the hue and visual assessment values was conducted to find the relationship between them.
