Abstract:
:The aim of this study was to characterize and to evaluate the lipidic composition of mexican marine fishes with special emphasis in n-3 fatty acids as nutraceuticals. The edible portion of 25 species: humidity (H), crude protein (CP), total lipids (TL) and fatty acids (FA). The average content (g/100g edible portion) of H was 75.20, PC was 18.40, TL was 3.60. Four n-3 FA were identified in all the samples and they were found in the next abundance order (mg/100g edible portion): C22:6n-3 (DHA)(229.60), C20:5 n-3 (EPA)(52.10), C18:3 n-3 (ALA)(11.80) and C20:3 n-3 (2.25). By their origin and climate there were no difference. By their biologycal classification, n-3 FA content was higher in bony fishes than cartilaginous fishes. It was detected a proportional relation with the n-3 FA concentration and total lipid content. According to their ecotic distribution there were numerical differences in DHA content (mg/100g edible portion) between pelagics (420.70), benthopelagics (125.30) and demersals fishes (225.40). Fatty fishes had higher content of EPA and DHA (mg/100g edible portion) (109.27 and 552.72) than semifatty fishes (56.12 and 226.29) and leanness (15.95 and 96.52), respectively. Bony, fatty and pelagic fishes had a higher content of EPA+DHA. According with the international recommendation values (200 to 600 mg EPA+DHA/day) the 44% of the analyzed species could be considered as functional foods due to their high content of EPA + DHA in a range of 220 to 1300 mg/100g.
