dc.description.abstractABSTRACT: A novel, inexpensive strategy was used to valorize fish canning industry by-products, aiming at ω-3 compounds and biodiesel production. Winterization and urea complexation methods were used to fraction the oil extracted from fish canning industry wastes. Urea complexation was the most efficient method, producing a liquid fraction with 99.99% (w/w) of polyunsaturated fatty acid methyl esters (FAME) when methanol was used as solvent, and a solid fraction with 79.94% (w/w) of saturated and monosaturated FAME when ethanol was used as solvent, which was considered a potential feedstock for biodiesel production. The liquid fraction was further analysed by preparative HPLC analysis, producing an oil fraction with 99.44% (w/w) ω-3 compounds, containing 89.25% eicosapentaenoic acid (EPA) (w/w). The method here described has an enormous potential for fish canning industry waste valorization as it is easily scale-up, foreseeing an environmentally sustainable society.pt_PT
