Abstract

Fish oil was extracted from two types of fish waste samples obtained from surimi processing plant i.e. fish waste FW consisting mainly of scales bones fins and tails and leaching fish waste LFW samples containing soluble proteins enzymes pigments blood and lipids. Three extraction methods were used namely Bligh Dyer method wet reduction method and acetone extraction method. In wet reduction method FW and LFW was subjected to four different conditions of heating temperatures and time in which the optimum condition was found to be at 85C for 50 min. The Bligh Dyer method gave the highest fish oil yield of 8.5 and 57.2 from FW and LFW respectively. From wet reduction method yields obtained were 3.6 from FW and 46.6 from LFW whereas from acetone extraction method yields were 1.4 from FW and 38.2 from LFW. Gas chromatography GC analysis fOf fatty acid composition showed that fish oil obtained from FW was abundant in C16:0 C18:1n9 C22:5n3 C22:6n3 and C20:5n3 while LFW was mostly rich in C20: 1n9. Fish oil from FW extracted by acetone extraction method had the highest eicosapentaenoic acid EPA content 1.67 and docosahexaenoic acid DHA 3.15. Quality indices of the fish oil including free fatty acid FFA acid value AV and peroxide value PV. This study indicated that fish wastes from the surimi processing industry normally considered as waste materials could be utilized to obtain fish oils. This would enhance the value added application of these fish by-products.
