Valutazioni comparative sulla conservabilità di Sparidi allevati

In this study 75 specimens of Sparus aurata,Diplodus sargus, Dentex dentex x Pagrus major(Pantice), Pagrus major and Dentex dentex, wereanalysed for the shelf-life assessment, during +2°Cstorage. The assessment regarded the applicationof Quality Index Method, bacteriological analysis,the evaluation of muscle ATP consumption, pH,dielectric properties, and the determination ofproteolytic activity of the sarcoplasmic fluids.Sparus aurata was the specie that showedthe most stable sensorial and bacteriologicalcharacteristics as well as a most regular ATPconsumption; it was followed by Dentex dentex,Diplodus sargus, Pantice and Pagrus major.These differences have shown the importanceto integrate the shelf-life modelling techniqueswith more specie-specific parameters. Finally, theAuthors drawn attention to the necessity of usingan analytical integrate approach regarding thehygienic and qualitative aspects in the context ofthe introduction of “alternative” reared species.[...]
