The aim of this study was to investigate the effect of salting and packaging treatments on liquid-smoked rainbow trout fillets during refrigerated storage (4°C) for 120 days. Treatments included the following: V1 (vacuum packaged-35% brine), M1 (modified atmosphere packaged-50% CO 2 + 50% N 2-35% brine), V2 (vacuum packaged-70% brine) and M2 (modified atmosphere packaged-70% brine). Fillets were subjected to microbiological (total aerobic mesophilic bacteria, psychrotrophic bacteria, Pseudomonas, lactic acid bacteria, Enterobacteriaceae, yeast and mould) and chemical (pH, thiobarbituric acid reactive substances-TBARS, total volatile base nitrogen-TVB-N) analyses on 0, 15, 30, 45, 60, 75, 90, 105 and 120 th days. The number of microorganisms, TBARS and TVB-N values increased according to increment of storage. Modified atmosphere packaging (MAP) gave better results than vacuum packaging in terms of all investigated parameters. Moreover, M2 was effective in extending the shelf life of rainbow trout fillets.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
