Enrichment test of omega-3 fatty acids from tuna canning waste oil in Bitung North Sulawesi Indonesia have been conducted. The purpose of this study was to utilize tuna canning waste oil and enriched the concentration of omega-3 fatty acids with urea crystallization. The results showed that the characteristics of fish oil quality of tuna canning waste 0.9% moisture content, free fatty acids (FFA) 3.4%, copper (Cu) 0.1 ppm, iron (Fe) 2.5 ppm and phosphorus (P) 32,5 ppm still meets IFOMA quality standards Liquid fatty acid profile contains total SFA 33.7%, 27.6% PUFA, 1.4% omega-6 fatty acids, omega-3 fatty acids 25.9%, EPA 4.2% and DHA 21.4%, MUFA 18.8%, omega-9 fatty acids 13.9%, while concentrations of omega-3 fatty acids contained a total SFA of 7.7%, PUFA 70.9%, omega-6 fatty acids 0.8%, omega-3 fatty acids 70.1%, EPA 4.2% and DHA 21.4%, MUFA 2.7%, omega-9 fatty acids 1.5%. The urea crystallization process increases the levels of polyunsaturated fatty acids (PUFAs) such as omega-3 (EPA and DHA.), the enrichment rate is 2.7 times.
