Abstract
  • In the framework of the DeCroMed Project, we used a multi-parametric approach to study the quality of the shrimp Parapeneus longirostris, and the lobster Nephrops norvegicus, during post-thawing periods. The quality of crustaceans as food products can be affected by environmental pollutants as well as by practices taking place during catching, handling, processing and storage. In this study we analysed by a multi-parametric approach the muscle exudates obtained by centrifugation from thawed specimens. We measured the water-holding capacity of P. longirostris and N. norvegicus and monitored changes in pH, protein content and composition of muscle exudates obtained by centrifugation. In addition, we evaluated the levels of a few candidate marker proteins, chosen from a list of biological markers known to predict the quality of food products and validated for their responsiveness to pollutants. Our results indicate that HSP70 protein levels and the analysed parameters are related to the quality and shelf life of crustaceans. Based on these results we defined a molecular assay that will be used to build a prototype device able to test the quality of crustaceans, and eventually their exposure to pollutants.
