Aplicación de sistemas avanzados para la mejora de la calidad de productos marinos refrigerados de interés comercial

Zusammenfassung

The aim of this work was to apply advanced refrigeration systems for the quality enhancement of marine products with high commercial interest. Thus, in the first part ozonised slurry ice was assessed for sacrifice, cooling and storage of a representative continental aquaculture species (rainbow trout). Additionally, a slurry ice system made from ozonised sea water was investigated in order to be applied on different kinds of bivalve species (mussel, clam y oyster). Nextly, the use of natural organic acid mixtures (citric, ascorbic and lactic acids) was analysed, according to their antimicrobial and antioxidant properties. For it, ice prepared from aqueous solutions including different concentrations of such acids was applied to different fish species such as hake, megrim, angler, horse mackerel, blue whiting and Atlantic mackerel. Finally, the effect of essential oil (oregano and thyme) presence was studied in ready-to-eat squid rings, as well as its combination with modified atmosphere packaging.
