INSPECTIVE AND HYGIENIC-SANITARY EVALUATIONS ON Centrolophus niger

Abstract

A preliminary study was carried on n. 11 specimens of Centrolophus niger fished along Ionian coastlines in province of Catania and Siracusa (Sicily) in order to determine sensory parameters and hygienic characteristics after 0, 3 and 5 days of storage at 3±1°C as well as the chemical composition and nutritional value. An increase of Mesophilic aerobic plate count and specific spoilage organism number was observed in skill and gill samples. Frequently gut contamination was very low. In all samples Echinophallus wageneri and Amphicotyle heteropleura were found in the pyloric caeca. The muscle was particularly rich in proteins (15.41%), poor in lipids (1.28%) and with a good correlation between w3/w6 fatty acids.
