Volatile and biogenic amines from three batches of anchovies, marinated in vinegar, were studied. The anchovies had been vacuum-packed and kept in refrigerated storage for 3 months. Trimethylamine and total volatile basic nitrogen levels were very low and constant throughout marinating and storage process: less than 1 and 10 mg/100 g, respectively. Certain amine levels, mainly those of tyramine and serotonin, increased slightly, particularly during storage. However, even the highest recorded levels were much lower than those considered to be hazardous for human consumption. To study the influence of raw material freshness in the amine profile, two laboratory trials using fresh and spoiled anchovies and simulating the industry standard marinating process were carried out. Levels for both volatile and biogenic amines were dependent on raw material quality, proving consistently higher in those deriving from nonfresh fish. Vinegar marinating leads to a decrease in the accumulation of amines in anchovy while their concentration in the vinegar solution increases due to the vinegar effect as solvent extractor.
