What the research is about
The aim of this work was to develop a quality index method (QIM) scheme for whole ice-boxed refrigerated blackspot seabream and to perform shelf-life evaluations, using sensory analysis, GR Tor-rymeter measurements and bacterial counts of specific spoilage organisms (SSO) during chilled storage.
Research conclusion
Shelf-life of 12 to 13 days was defined for whole raw blackspot seabream stored in ice. The shelf-life was determined by the sensory scores, Torrymeter measurements and microbio-logical data of SSO. A QIM scheme is proposed in this study; as with other QIM schemes, the future use of this table will probably induce some adaptations and minor changes.
Assurant Innovations take
The Fish Freshness Meter (Torrymeter) was used as the golden standard to compare the results of fish freshness against sensory and Quality Index Method (QIM).
