Considering
the polyunsaturated EPA and DHA fatty acids, all
brands showed high levels of EPA, and this is possibly
due to retroconversions of DHA to EPA (Aubourg,
Sotelo, & Gallardo, 1990). By analyzing only the EPA
values of the brand P (5.39%), significant differences
(P < 0:05) in comparison to the other brands were observed.
However, the DHA values, varying from 3.89%
to 6.64%, were the same (P < 0:05) among the brands.
