ABSTRACT: The present study was conducted aiming at establishing chemical quality
parameters to assess ice stored mullet (0℃ ± 1℃) through the evaluation
of nucleotide (adenosine monophosphate [AMP], inosine [HxR] and hypoxanthine
[Hx]) degradation, biogenic amine (histamine [HI], putrescine [PU], cadaverine
[CA] and tyramine [TI]) quantification and mesophilic and psychrotrophic bacteria
count monitoring. The microbial load of 7 log CFU·g–1 established as
maximum acceptable limit was attained after the 20th day of ice storage. IMP
concentration declined during the storage period to levels below the detection
limit. HxR content increased only up to time T3 and then declined. Hx level
increased during all the storage period. CA and HI content increase was not observed,
on the other hand, PU and TI contents significantly increased (p ℃ ± 1℃ can be consumed up to
the 20th storage day.
