Abstract

The oil yield from liver of the trash fish Odonus niger was asessed by four different
methods : Soxhlet, Bligh and Dyer, direct steaming and solar extraction.
The percentage of oil yielded by Soxhlet method was maximum (67.78%), followed
by direct steaming (42.58%), Bligh and Dyer (54.3%) and solar extraction
method (32.08%). The physico-chemical parameters such as solidification point,
specific gravity, refractive index, cholesterol level and fatty acid profile of extracted
oils were estimated separately. The solidification point was 29.0 ± 0.5°C.
The specific gravity ranged between 0.9519 to 0.9581. The refractive index was
also almost similar in all the four oils (1.426 to 1.483μ). The cholesterol contents
of the oil extracted by Bligh and Dyer, direct steaming extraction methods
were highest (1950 and 2059 mg 100-1ml) and it was nearly 50% less in other
two methods. The percentage of PUFA in the total fatty acids of the oils were
13.78, 20.46, 19.07 and 22.54% (by weight) in solar extraction, direct steaming,
Soxhlet and Bligh and Dyer methods respectively.
