RANCIDITY DEVELOPMENT DURING FROZEN STORAGE OF FILLETS FROM GILTHEAD SEABREAM (Sparus aurata) REARED IN ITALY

Lipid oxidation indices (Free Fatty Acids-FFA, Peroxide Value-PV and Thiobarbituric Acid-TBA) were evaluated in frozen fillets from seabream reared in Italy in: land based facilities (recirculation systems), lagoons or net-cages. Statistically significant differences emerged among seabream sources for all indices. Quality loss related to rancidity seemed to have been affected by both storage time and culturing system.
