Assessment of Safety, Nutritional, and Spoilage Characteristics of Different Lagoon Grey Mullets (Liza ramada, Liza aurata, and Liza saliens)
Abstract:Different lagoon grey mullets such as Liza ramada (thinlip mullet), Liza aurata (golden grey mullet), and Liza saliens (leaping grey mullet) were analyzed for their nutritional, microbiological, and safety parameters. The microbiological values never exceeded the lower limits stipulated by the Italian Higher Institute of Health. The pathogenic species frequently associated with seafood (Salmonella, Listeria monocytogenes, Vibrio cholerae, Vibrio parahaemolyticus, and Aeromonas hydrophila) were never detected. The absence of coliforms and of Escherichia coli was noted in all fish species after 4 days of storage in ice. Heavy metals such as cadmium and mercury were always below the detection limits (0.01 mg/kg). All three fish species had low levels of total biogenic amines (80 to 100 mg/kg), and the presence of histamine was sporadic. All Liza species, particularly L. ramada and L. saliens, are a good source of 3 long-chain polyunsaturated fatty acids.
