title: Nutritional and lipid profiles in marine fish species from Brazil.
abstract: Centesimal composition and lipid profiles were evaluated in muscle tissue of four species of Brazilian fish using the Kjeldahl and Bligh & Dyer gravimetric methods and gas chromatography, respectively. The moisture, protein, total lipid, and ash values (g/100g) ranged from 71.13 to 78.39; 18.10 to 19.87; 1.05 to 9.03; and 1.03 to 1.73, respectively. Palmitic acid was prevalent among the saturated fatty acids (10.89-20.38%) and oleic acid was the main monounsaturated acid identified (4.26-15.77%). The eicosapentaenoic-EPA (6.41-10.66%) and docosahexaenoic-DHA (9.12-30.20%) acids were the most prevalent polyunsaturated acids. The average values, which are indicative of nutritional quality, were: Polyunsaturated/saturated (P/S) (1.11-1.47), ω6/ω3 (0.08-0.21), hypocholesterolemic/hypercholesterolemic acid ratios (HH) (0.87-2.43), atherogenicity index (IA) (0.26-0.60), and thrombogenicity index (IT) (0.20-0.44). These results demonstrated that the lipid profiles of the studied species are of nutritional quality.
