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
