Abstract

CIAPPINI, María C.; GATTI, María B.; CHAIN, Priscilla N.  and  CABRERISO, María S.. Lipid profile of three species of freshwater fish: Boga (Leporínus obtusidens), Dorado (Salminus brasiliensis) and Surubí (Pseudoplatystoma coruscans). Rev. cienc. tecnol. [online]. 2019, n.32, pp.1-10. ISSN 1851-7587.

The knowledge of the lipid composition of freshwater fish is scarce, despite contributing to the diet with beneficial fatty acids for health. In this work the fat, moisture, proteins, ashes and fatty acid profile of Boga, Dorado and Surubí were determined. The protein content ranged between 15 and 18 g/100 g for the three species. Dorado can be considered as lean fish (2.8 g/100 g), while Boga (8.6 g/100 g) and Surubí (16.9 g/100 g) as fatty; the saturated AG / unsaturated AG ratio approached 1:2, with n-6-AG predominating. Surubí had the highest content of eicosapentaenoic (EPA) and docosahexaenoic (DHA) per edible portion. Due to its predominance of unsaturated fatty acids, the consumption of these species can be recommended, as part of a healthy diet.

Keywords : Boga; Surubí; Dorado; Lipids; Fish.
