Abbreviations: SFA, saturated fatty acids; MUFA, monounsaturated fatty acids; PUFA, polyunsaturated fatty acids. Oil analysis was performed in quadruplicate, and all data are expressed as mean values ± standard deviations (SD); (n = 4). Evaluation of the statistical significance of differences between the two groups was performed using the Student's unpaired t-test with Welch's correction; ap < 0.01; bp < 0.05.
