Abstract

 The effect of the ANTIOXIDANT extracts on the quality indices of rainbow trout fillet stored at refrigerator (4±1ºC) for 15 days was investigated. The fillets in 3 treatments, including salted in 10% brine, salted in 10% brine plus 1% nettle leaf extract, and salted in 10% brine plus synthetic ANTIOXIDANT BHT were evaluated at every 3 days interval, using the quality indices including the free fatty acids (FFA), thiobarbituric acid (TBA), peroxide (PV), moisture content, pH levels and sensory characteristics. The results showed that TBA and FFA values increased significantly (p<0.05), but PV significantly decreased in all treatments during the course of storage (p<0.05). Samples containing ANTIOXIDANTs had significantly lower TBA, PV and FFA values in comparison with the control sample throughout the storage. Also, the methanol extract from nettle leaves (at 1% balance) controlled the TBA, PV and FFA indices and entirely replaced the synthetic BHT ANTIOXIDANTs (at 1% balance). Since the sensory evaluation (smell, texture, taste and after taste elements) showed no significant differences between the two ANTIOXIDANTs, both are recommended to preserve the quality of rainbow trout fillet. The nettle leaf extract was found to be more efficient on SHELF LIFE extension the fillet.
