Values are expressed as μg/g f.w. and represent the mean ± standard deviation of three independent replicates ( = 3). Data were submitted to one-way analysis of variance (ANOVA); values marked with different letters indicate statistically significant difference between samples for a given carotenoid (Holm-Sidak post hoc test, < 0.05).
