Characteristic Squalene compounds Shark Liver Oil of home industry product in Pelabuhan Ratu
AbstractOmega-3, omega-6, omega-9 fatty acids and Squalene are active components of fish oil that are
beneficial to human health. Squalene is mostly contained in shark liver oil (Centrophorus sp.). The aim
of this research was to determine the quality and characteristics of shark fish oil of household production
in Pelabuhan Ratu. The analyses performed were to determine fatty acid profile, primary and secondary
oxidation and characteristics of squalene contained in the shark liver oil. The fatty acid profile showed
that the dominant fatty acids of shark liver oil were oleic acid (28.22%), Eicosapentaenoic Acid (1.54%)
and Docosahexaenoic Acid (4.78%). The results of primary and secondary oxidation measurement showed
shark liver oil contained a high oxidation value of PV (17.73 mEg/kg), p-AV (29.32 mEg/kg), TOTOX
(64.78 mEg/kg) and FFA (4.65%). The values of density and viscosity of the shark liver oil 0.91 g/cm3 and
38.18 cPs. Clarity of shark liver oil at a wavelength of 450 nm was 84.98%. GC-MS chromatogram showed
that squalene peak appears at the retention time of 23.357 with a total area of 12.49% and its molecular
weight was 410.391 g/mol.
