RESUMO
Numerous investigations have pointed out the importance that the fatty acids have in the process health-illness, and that the marine resources are excellent sources of the series omega 3 and omega 6. In Mexico, the sardine is a product of marine origin of wide consumption due to its high readiness and low cost. The objective of the present study was to determine the fatty acids profile (FA) in sardine canned in tomato sauce coming from different fishing areas (A) of the Mexican Pacific. There were randomly obtained 8 commercial mark (5 cans of each mark) of sardine canned in tomato sauce; they were classified in sardine of South Baja California Sur (A1), Sonora (A2) and Sinaloa (A3). The samples without draining were liquified and thereafter were obtained the methyl esters of fatty acids that were analyzed by gas chromatography with a flame ionization detector. In all the areas they were identified and quantified as 3 FA omega 3 (linolenic, EPA and DHA) and 2 AG omega 6 (linoleic and arachidonic); this source is rich in FA monounsaturated and also presents a considerable quantity of trans FA (181n9t and 182n6t). The DHA was the most abundant AG in all the areas (3064-4704 mg/100 g); finally, the relationships omega 3/omega 6 were from 3.5 (A1) up to 8.9 (A3). In conclusion, sardine canned in tomato sauce of the mexican Pacific is a rich food in omega-3 and omega-6 FA, independently of the processing area.
