Mean ± SD (n = 3).

Statistical analysis was carried out by using mutivariate analysis and Tukey's HSD test.

^abcdeValues with different superscripts letter within a row in each oil are significantly different (p < 0.05; one-way ANOVA and Tukey's HSD test).

L*: lightness of oil sample (black = 0 and white = 100).

a*: +ve = redness and –ve = greenness.

b*: +ve = yellowness and –ve = blueness.
