Abstract :During enzymatic hydrolysis of trout insert ignore into journalissuearticles values(Onchorhunchus mykiss); by-products four lipid containing fractions were generated: oil, emulsion, fish protein hydrolysates and sludge. The raw material consisted of combinations of viscera, backbone and digestive tract and was hydrolysed with Alcalase enzyme at different time and temperature and determined fatty acid compositions of extracted oil from these waste. As a result of study, highest amount of fatty acids detected in the oil fractions extracted from trout waste by using alkali protease enzyme for all temperature were total mono-unsaturated fatty acids insert ignore into journalissuearticles values(44,05%-46,46%); followed by total polyunsaturated fatty acids insert ignore into journalissuearticles values(23,12%-24,41%); and total saturated fatty acids insert ignore into journalissuearticles values(21.94%- 23.74%);. The highest total saturated fatty acids insert ignore into journalissuearticles values(ƩSFA);, total polyunsaturated fatty acids insert ignore into journalissuearticles values(ƩPUFA);, total n6 fatty acids insert ignore into journalissuearticles values(Ʃn6); of the trout wastes hydrolyzed at 40 C and 50 C were obtained after 4 hours of hydrolysis insert ignore into journalissuearticles values(p <0.05);. The reaction time had significant effects on the fatty acid compositions of extracted oil fraction. It can be recommended that the waste can be an important additive that can meet the fatty acid requirement of human and the cultivated species.
