Abstract
AIMS: ) at 4 and 8°C. METHODS AND RESULTS: H nuclear magnetic resonance (NMR) spectroscopy. The concentration of trimethylamine (TMA) was significantly affected by storage time and temperature, packaging atmosphere and inoculation with A. salmonicida (General Linear Model (GLM), P < 0·001 for all factors). CONCLUSION: did not completely inhibit the growth but prevented the formation of TMA. SIGNIFICANCE AND IMPACT OF THE STUDY: Little information is available on the spoilage potential of Aeromonas spp. in minimally processed salmon products under different packaging conditions. The study clearly demonstrates the importance of hurdle technology and provides data to further elucidate the significance of Aeromonas spp. as a spoilage organism.
