Trimethylamine Formation in Fillets of Yellowfin Tuna as an Index of Freshness: Variation With Storage Time and Temperature

G. Esparaz, G. J. B. Cajipe


Trimethylamine in fillets of yellowfin tuna was determined qualitatively by paper chromatography and quantitatively by monitoring the absorbance of the trimethylamine picrate salt at 410 mm. The results show that the concentration of trimethylamine increase with storage time and temperature.
