Abstract Quality and freshness of thirty nine samples of fresh
and frozen fish sold in the super markets of Cochin
were determined in terms of biogenic amine
content, biochemical and microbial parameters. The
contents of putrescine, cadaverin, histamine, agmatine,
tyramine, spermine and spermidine were
analysed and it showed a wide variation with higher
content of spermine and cadaverine. Histamine
content was less than 5 mg kg-1 (Range: Nd - 2.19±0.6
mg kg-1). Putrescine, cadaverine, agmatine, tyramine,
spermidine and spermine were in the range of Nd
– 7.72±1.7 mg kg-1, Nd – 52.8 mg kg-1, Nd – 6.22
mg kg-1, Nd – 4.34 mg kg-1, Nd - 51.8 mg kg-1 and
0.21- 43.95 mg kg-1 respectively. Levels of putrescine
and cadaverine were highest in Rastrelliger kanagurta
and Lethrinus nebulosus. In the present study 10.3%
of samples exceeded Biogenic amine index (BAI)
value of 20 mg kg-1. Around 7.7% of samples were
having TVBN content more than 30 mg% and 10.3%
of samples were having APC greater than or equal
to 7 log cfu g-1. As indices based on biogenic amines
are not highly correlated with other quality indices,
assessment of biogenic amine indices along with
other quality indices for fresh fish can be recommended.
