Abstract
In the present study, fatty acid profile of yellowfin
tuna eye (YFTE) was investigated. Proximate analysis
of YFTE revealed the presence of high fat content
(12.0%) and moderate protein content (10.2%). A
comparison was made between the fatty acid
composition of YFTE and sardine oil. Higher poly
unsaturated fatty acid content was found in YFTE
(48.8%) compared to oil sardine (30.0%). Ratio of
docosahexaenoic acid (DHA) content to the total
fatty acids of YFTE was 36.72% which was higher
compared to oil sardine (8.67%). However, EPA
content of oil sardine was higher (16.8%) than YFTE
(7.07%). DHA/EPA ratio and n-3/n-6 ratio of YFTE
were 5.25 and 8.97 respectively. Palmitoleic acid was
the principal mono unsaturated fatty acid (MUFA)
present in YFTE and oil sardine. The present study
revealed that yellow fin tuna eye could be a
potential source of omega-3 fatty acids.
