On the Compositions of the Horse-mackerel, Mackerel, Sea-eel (Astroconger myriaster;Muraenesox cinereus), Sillago sihama, Sciana schlegellii, Bass, Surf-fish, Gilthead and Red-porgy Oils

Abstract

The oils were obtained from the above mentioned fish by the ether extraction.
The properties of the oils (Table-2) and the components of the fatty acids (Table-37) were examined.
Iodine value of the above mentioned oils had, in general, 120160. From the result of the gas chromatography of the methyl esters of the fatty acids obtained from those oils, there were not distinct differences on the compositions among the body, internal organs and liver oils.
The fatty acids were composed of C₁₀C₂₂ saturated and C₁₂C₂₂ unsaturated (higher unsaturated C₂₀ and C₁₂) acids.
