aFatty acid composition, total fat, and cholesterol of SRM are presented as mean and recovery. The recovery was calculated with respect to certified/standard mass fraction results of each parameter of SRM. bThe phytosterol were spiked in three levels/concentrations (L1, L2, and L3), and % spiked recovery is presented as .
