It is a well known fact that the lipid (oil) extracted from various fish species can be of industrial benefit if properly extracted and processed. In this study herring fish oil was analyzed using quantitative and qualitative analysis in other to provide an assessment of the quality of the oil for industrial purposes. This work focuses on the production of oil from frozen herring fish (Clupea harengus) as the raw material readily available on the market, by evaluating by the oil using chemical and physical analysis and refining the oil by degumming, neutralizing, drying, and decolorizing. The experimental results revealed that the rate of extraction increases with time until maximum extraction took place using an average size of 780 p.m. Every 10.64 g of dried sample used has about 4.34 g of oil extracted for five hours. The extracted herring fish oil contains two essential unsaturated fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which could be of great industrial importance.
