    The effect of vacuum packaging on physicochemical changes in rainbow trout (Oncorhynchus mykiss) during cold storage

  • Original language description

    The aim of the study was to monitor changes in selected physical (aw water activity, pH values) and chemical (TVBN total volatile basic nitrogen, TMA-N trimethylamine nitrogen, FFA free fatty acids, PV peroxide values, TBA thiobarbituric acid value) parameters in the shelf life of rainbow trout (Oncorhynchus mykiss) muscle. A total of 192 trout were examined. Control samples (96 samples) were simply packaged in contact with atmospheric oxygen, while experimental samples (96 samples) were packaged in a commercial vacuum (98 %). All the samples were stored at 2 +- 2o C for 11 days. Analyses were performed on storage days 1, 2, 4, 7, 9 and 11. During the experiment, aw values increased in both types of packaging (in air: 0.982; vacuum-packaged: 0.989). Atthe end of storage, TVBN and TMA levels were at 28.88 +- 4.42 and 19.28 +- 3.00 g mg.100-1, respectively, in the muscle of vacuum-packaged trout, and at 30.52 +- 2.91 and 19.94 +- 2.05 mg.100 g-1, respectively, in fish in simple packagin
