Abstract

Fish and fish oil is the major source of polyunsaturated fatty acids (PUFA). These PUFA are variously important for human health. In this experiment, the most cheap and fatty fish species was used for the extraction and identification of PUFA using soxhlet extraction method and gas chromatography (GC) analysis revealed that 0.80%, 2.48% EPA and DHA were present in the test sample, respectively. The level of different fatty acid content range between 0.03% to 22.6%. Therefore, the objective of this study was to extraction and identification of PUFA from the cheaply available catfish waste part (skin) for the rural poor Bangladeshi.
