Estimation of amino acids profile and escolar fish consumption risks due to biogenic amines content fluctuations in vacuum skin packaging/VSP during cold storage

Abstract The aim of the study was to establish quantitative and qualitative composition of proteins (amino acids profile), digestible lipids (fatty acids profile of triacylglycerols) and to monitor biogenic amines (especially histamine) content of escolar fish ( Lepidocybium flavobrunneum ) in vacuum and vacuum skin packaging (VSP) during 9 days of storage at +2 ± 2 °C. L. flavobrunneum Fillets packed in vacuum were used for comparison as control samples. The obtained results from our research showed that escolar fish contains higher amount of essential amino acids (70.63 ± 3.61 mg/kg) and good ratio between essential and non essential amino acids (0.95 ± 0.09). Oleic and elaidic fatty acids were the most abundantly present in our samples (28.115 ± 4.44%). Initial values of biogenic amines sum were low but they increased significantly (p
