Valorization of Marine Coproducts for the Production of Food Supplement

The main aim of this study is the extraction of oil from fish by-products through a conventional method, namely wet pressing, followed by a refining process aimed to lower a compounds that impair the oil’s stability, quality, and acceptability without losing the PUFAs. Furthermore, we discussed characterization of oil, who revealed a good organoleptic and nutritional quality, a high percentage of omegas, an acceptable antioxidant activity and without any antibacterial activity. The results show that the by-product generated from Xiphias gladius co-products can be used as a dietary supplement.
