Data are presented as mean ± SE (n = 2). Values within the same row with different letters mean significant difference. Fatty acids contents < 0.5% are not listed in this table. ∑SFA: total saturated fatty acids; ∑MUFA: total monounsaturated fatty acids; ∑PUFA: total polyunsaturated fatty acids; ∑LC-PUFA: total long chain polyunsaturated fatty acids.
