What the research is about
Dielectric properties and sensory assessment of sea bass (Dicentrarchus labrax, L.) stored under six different conditions over a period of 75 hours were investigated. Declines of the Fish Freshness Meter (Torrymeter) values over time were established under all storage conditions but showed variability. The correlations between the Fish Freshness Meter (Torrymeter) readings and Quality Index Method (QIM) results were studied. Significant negative correlations were found between QIM results and Fish Freshness Meter (Torrymeter) readings for samples stored in sea water (20 to 22C), storage room (16 to 18C), refrigerated room (2 to 4 C) and sea water (10 to 12 C). QIM and torrymeter values in slurry ice and ice box samples were not in correlation.
Measuring dielectric properties alone is not an “absolute” in fresh fish quality assessment although, in combination with sensory analysis,fish muscle conduction ability is a practical and objective measurement of fish quality.
Assurant Innovations take
The Fish Freshness Meter (Torrymeter) did not correlate well under the conditions in this experimental study. It concludes that the Fish Freshness Meter (Torrymeter) alone could not be used to determine fish freshness.
