Data are expressed as the mean and standard deviation (± SD), n = 12. Results in the same column followed by different letters indicate significant differences according to Duncan’s test at p < 0.05 between different flesh colors and varieties (small letters), and between time (big letters), as determined and via one-way ANOVA. LSD—least significant difference.
