Summary

The evolution of perioxide value (PV), fluorescent compounds, diene, triene and polyene indices as well as the level of alpha-tocopherol during 15 days is studied. A significant linear increase (P lower than 0.001) of PV, diene, triene, and fluorescent compounds with storage up to 6 days was obtained. Simultaneously, a fast reduction of the level of alpha-tocopherol was registered being not detected at the 4th day. On the other hand, only a slight decrease of the polyene index was observed. Triene seems to be the most adequate to follow sardine freshness due to its fastest rate of formation and the high coefficient of correlation obtained.
