Monitoring and controlling the quality of frozen fish is one of the fundamental worries of the seafood industry. Many parameters are involved in the definition of quality, including safety, nutritional and sensory properties, price, convenience and constancy, packaging color, availability and freshness (Olafsd ottir et al.,1997; Souza et al., 2010). The change of one of these parameters affects largely the product acceptability by the consumers and consequently also its commercial value (Rodriguez-Turienzo et al., 2011). Freshness is one of the most important parameters for the quality of the final product (Olafsd ottir et al., 1997 ).
