Data are presented as mean ± SD (n = 3). Values in the same row with different superscripts are significantly different (p < 0.05). Some fatty acids, of which the contents are minor, trace amount or not detected, such as 12 : 0, 20 : 0, 22 : 0, 24 : 0, 22:1n-9, 22:1n-11, 20:2n-6, 20:3n-6, 22:4n-6, 20:5n-6, and 20:3n-3, were not listed in this table. ^aSFA: saturated fatty acids; ^bMUFA: monounsaturated fatty acids; ^cn-6 PUFA: n-6 polyunsaturated fatty acids; ^dn-3 PUFA: n-3 polyunsaturated fatty acids; ^en-3 LC-PUFA: n-3 long chain poly-unsaturated fatty acid; ^fARA/EPA, the ratio of ARA to EPA; and ^gARA/DHA, the ratio of ARA to DHA.
