RESUMO

This study aimed to determine centesimal composition, cholesterol content, fatty acid profile, and caloric content of some commonly commercialized fish species from two environments in Alagoas State, Brazil. Samples of 80 fish fillets of four species. carapeba-listrada (Eugerres plumieri Cuvier, 1830) and mackerel (Scomberomorus cavala Cuvier, 1829) from Alagoas coast; and mullet (Mugil cephalus Linnaeus, 1758) and camurim (Centropomus undecimalis Bloch, 1792) from the Mundaú Lagoon Estuary Complex, a marine-estuarine environment, were analyzed. The samples analyzed presented high moisture for camurim and carapeba-listrada. The mackerel and mullet presented the largest protein percent content. The total lipid contents of all samples were similar. As to ash content, the mackerel and camurim presented the largest values. The largest caloric contents were found for mackerel and mullet. In relation to cholesterol contents the mullet and camurim had the eminence. Fatty acid contents, saturated (palmitic acid, pentadecanoic acid, heptadecanoic acid, tetradecanoic acid, dodecanoic acid, and stearic acid), monounsaturated (heptadecenoic acid, oleic acid, and 9-hexadecenoic acid), and polyunsaturated (linoleic acid, α-linolenic acid, arachidonic acid, eicosapentaenoic acid, docosapentaenoic acid, and docosaexaenoic acid) were analyzed. Marine mackerel and estuarine mullet are the most indicated fish in nutritional terms due to their content lipid-protein and eicosapentaenoic and docosaexaenoic acid contents. This information will be valuable for later inclusion in the Regional/National Food Composition Table.
