Popis: Postmortem changes of Finescale triggerjish muscle during 20 days of storage at OC were evaluated by monitoring changes in chemical, biochemical and microbiological parameters. The K value increased linearly fi-om an initial value of 3.5% to 43.3% at day 20. pHfluctuatedfiom 6.38 to 6.55. TMA-Nand TYB-N remained below critical limits with final values of 1.18 mg TMA-NAOO g muscle and 29.7 mg TVB-N/lOO g muscle, respectively, suggesting a low microbial activity. Composition of muscle protein fractions was not aflected during the storage period; however, an initial high level of alkali-soluble protein was detected. The overall results indicated that triggerfish has excellent shelf-life on ice.
