Chemical Quality Indexes of Mullet (Mugil platanus) Stored on Ice

摘要

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.
