Determination of Quality of Marine Fishes Based on Total Volatile Base Nitrogen test ( TVB-N ) (original) (raw)

2014

This study was carried out to evaluate the quality of five marine fishes yellowfin tuna (Thunnus albacores, Bonnaterre, 1788), sailfish (Istiophorus platypterus, Shaw, 1792), slaya/sardine (Sardinella gibbosa, Bleeker, 1849), squid (Loligo duvaucelii, D' Orbigny, 1835) and shrimp (Fenneropenaeus indicus, H. Milne Edwards, 1837) based on total volatile base nitrogen test (TVB-N). The studied fish was collected from 19 commercial retail outlets in Sri Lanka in 2012, kept under ice and immediately transferred to laboratory for further analysis. The total volatile basic nitrogen (TVB-N) test was performed to assess the quality status of fresh fish. The limits of TVB-N for fishery products in Commission Regulation (EC) NO 2074/2005, which was ranged between 25 to 35 milligrams of nitrogen/ 100grams of fish flesh. The results of the present study revealed that base the total volatile base nitrogen (TVB-N) content, 5% of yellowfin tuna, 8% of sailfish, 12% of sardine, 100% of squids an...
