Abstract

In this study, the antimicrobial effect of sea cucumber extract (0.5, 1 and 2%) on the microbial population of rainbow trout fillets during refrigerated storage was examined. Fillets were stored for 16 days and every 4 days microbial tests (including total bacterial load, Pseudomonas, Enterobacteriaceae and H₂S producing bacteria) were performed on the samples. Results showed that there was no significant difference (P > 0.05) for the total bacterial load in all treatments during the storage time. For the samples treated with the extract, Pseudomonas, Enterobacteriaceae and H₂S producing bacterial count was significantly (P < 0.05) lower than the control samples. Also among the different concentrations, 2% of the extract showed the highest antibacterial activity. The findings of this study showed that the sea cucumber extract could be a natural preservative for the storage of fishery products in the short-term storage in cold conditions.
