Abstract

In this study, 120 rainbow trout fish (Oncorhynchus mykiss) were prepared in six different groups and stored at refrigerator 28 days. During this time, the production of their biogenic amines (histamine, putrecine and cadaverine) were assessed. The groups were included as control, fresh rainbow trout fillet; treatment 1, packaged with modified atmosphere packaging (O2 5%, CO2 20%, N2 75%); treatment 2, dipped in Caper extracts (0.2%); treatment 3, dipped in Caper extracts (0.5%); treatment 4, dipped in Caper extract (0.2) and packaged with modified atmosphere packaging; treatment 5, dipped in Caper extracts (0.5) and packaged with modified atmosphere packaging. From each group, 4 samples were prepared and evaluated as triplicate at five times (0, 7, 14, 21, 28 days). The amount of histamine was significantly decreased at treatments 3, 4 and 5 in day 14 of refrigerator storage compared to other groups (P<0.05). The amount of putrecine significantly decreased at treatments 4 and 5 in day 28 compared to control (P<0.05). The amount of cadaverine significantly decreased at treatment 5 in day 28 compared to control and treatment 1 (P<0.05). In conclusion, these results showed that using of Caper extract associated with modified atmosphere packaging reduce the production of biogenic amines in rainbow trout fillet that increase its shelf life.
