Abstract
Lean fish such as barracuda, jaw fish and two types of fresh water cat fish were found to be organoleptically acceptable uplo 8 h at tropical ambienl temperature, but white bait, the smallest lean fish under study, was acceptable upto 4 h only. Fatty fish such as drift fish, scad, small mullet and mackerel were organoleptically acceplable upto 6h, while Indian herring. the biggest fatty fish under study, was acceplable upto 8 h, at ambient temperature. Histamine levels in all fishes except mackerel were below 10 mg/ 100 mg muscle, during storage at ambient temperature, but this level in mackerel was above the maximum admissible limit i.e., 20 mg/ 100 g muscle. The increasing trend of total volatile base nitrogen (TVBN) continent was noticed in all the stored fishes at ambient temprature. TVBN values in all the orqanoleptically acceptable fishes were between 11.7 and 24.6 mg %. Peroxide value (PV) in the fresh fatty fish was nil, but its increasing trend was noticed in all the stored fatty fishes at ambient temperature. The changes in accumulation of TVBN and histamine in all the fishes stored in ice were comparatively low at 24 h.
