Amino acids and biogenic amines determination in Mystus nemurus.
The concentration of biogenic amines, i.e., histamine, putrescine, and cadaverine were studied as indicators of Mystus nemurus muscle quality under different storage conditions, namely, ambient (28±2C), chilled (10±2C) and in iced (2±1C) temperature. The biogenic amine contents were found to correla...

| Summary: | The concentration of biogenic amines, i.e., histamine, putrescine, and cadaverine were studied as indicators of Mystus nemurus muscle quality under different storage conditions, namely, ambient (28±2C), chilled (10±2C) and in iced (2±1C) temperature. The biogenic amine contents were found to correlate with the free amino acids contents. The level of biogenic amines increased in accordance with decreasing free amino acids during storage (P<0.05). The cadaverine level reached a peak, 186.24mg/g, after 24h at ambient temperature, 371.98mg/g after 10 days at 10C, and 385.49mg/g after 20 days at iced temperature. Unacceptable levels were reached after 12h at ambient, 8 days at 10C and 16 days at 2C. Putrescine increased at a slower rate than histamine and cadaverine. The present study demonstrated the potential of cadaverine production as a quality indicator of M. nemurus during storage. |
