Data represent the means of triplicate analysis for each sample ± standard deviations;

2

T is storage time in months. SFA is saturated fatty acids. PUFA is polyunsaturated fatty acids. MUFA is monounsaturated fatty acids;

3

means with the same capital letters within a column are not significantly different according to Tukey’s multiple test (p < 0.05);

4

means with the same small letter within a row are not significantly different according to Tukey’s multiple test (p < 0.05).
