The data were subjected to analysis of variance using the SPSS
statistical package (ver. 14.0, SPSS Inc., Chicago, IL, USA). Differences
among means were established using the Duncan’s multiple
range test (P < 0.05). Pearson’s test was also conducted to determine
the correlation coefficient between sensory test and each colour
values using image analysis and colorimeter. Experimental
results are presented as means ± SD.
