The high concentrations of both fatty acids, when compared to
uncanned sardines, show the migration of fatty acids
from the coating-oil to the sardines. Significant differences
(P < 0:05) between the brands P (32.9%), C
(16.3%) and G (19.6%), for C18:2n ) 6 were observed,
while this did not occur between the brands P and B
(26.2%). The values of the C18:3n ) 3 fatty acid did not
significantly differ (P < 0:05) between the brands, except
for the brand P. The arachidonic acid (C20:4n ) 6), an
important precursor of prostaglandins, showed variations
(0.55–2.31%) among whole brands.
