[Determination of indole and skatole in seafood using high performance liquid chromatography (HPLC)]

Abstract:
A rapid and specific high-performance liquid chromatographic (HPLC) method for the determination of indole and 3-methylindole (skatole) is described. The detection limit of the two compounds is approx. 0.02 mg/kg. Gas chromatographic-mass spectrometric (GC-MS) confirmation of the identity has been carried out in shrimps. About 95% of added indole was recovered. The indole formation in shrimps, herring, and turbot, held under different storage conditions, is compared with other common quality indices such as TBA-value and alpha-tocopherol content.
