Resumo
Fish are a healthy source of protein, providing omega-3 (n-3) the fatty acids that reduce cholesterol levels, and
reduce the incidence of heart disease and stroke. The purpose of the present study was to assess the
concentration of some micronutrients and also fatty acids profile in muscles of the most consumed fish species
from Cubatão coastal region. Cubatão carnivorous fish species analyzed were: Micropogonias furnieri
(Corvina), Macrodon ancylodon (Pescada) and Menticirrhus americanus (Perna-de-Moça), and planktivorous
species Sardinella braziliensis (Sardinha) and Mugil liza (Tainha). Micronutrients (Ca, Fe, K, Na, Se, Zn) in fish
muscle were determined by means of instrumental neutron activation analysis (INAA). Fatty acids profiles in
these muscle fish samples were performed by gas chromatography. Total saturated fatty acids ranged from
23.0% in M. ancylodon to 50.0% in M. liza. Total polyunsaturated fatty acid contents varied from 10.9% in M.
liza 38.4% in S. braziliensis. These fish species presented different proportions of polyunsaturated fatty acids of
the n-3 family and of the n-6 family. Regarding the n-6 family, M. furnieri showed the highest values (13.3%)
and M. ancylodon, the lowest ones (4.1%). On the other hand, for the n-3 family, S. braziliensis presented the
highest value (31.8%) and M. liza the lowest one (5.7%). Regarding micronutrients content, great concentration
variations between individual of the same species and between different species were observed. From the
nutritional point of view S. braziliensis is the best choice showing highest content of fatty acid n-3 family and
micronutrient concentrations.
