Abstract Chemical composition viz., fatty acids, amino
acids and minerals of yellowfin tuna (Thunnus albacares)
eye were analyzed for better utilization of fish processing
discards. Analysis of fatty acids composition by gas chromatography–
mass spectrometry revealed the presence of
polyunsaturated fatty acids namely docosahexaenoic acid,
eicosapentaenoic acid, arachidonic acid and linoleic acid at
the levels of 37.8, 7.1, 3.6 and 1.4%, respectively. The
major available monounsaturated fatty acids, palmitoleic
acid and oleic acid were present at the level of 17.9 and
18.3% respectively. Myristic acid was the dominant saturated
fatty acid and occupied 2% of the total fatty acids.
Amino acid analysis by high-performance liquid chromatography
showed that the tuna eye has a high concentration
of glycine (19.24 mg/100 g) followed by glutamic
acid (16 mg/100 g) and aspartic acid (12.76 mg/100 g).
Analysis of mineral content of tuna eye showed the presence
of higher sodium and lower copper content. The
results revealed that yellowfin tuna eye could be used as a
potential source of x-3 fatty acids and essential amino
acids.
