“…Most of the separation methods applied to histamine in fish and fish products use reversed-phase high performance liquid chromatography (HPLC) with detection schemes based on pre-column derivatization (Hui and Taylor, 1983;Meitz and Karmas, 1978;Petridis and Steinhart, 1995;Malle et al, 1996;Hwang et al, 1997) or post-column derivatization (Veciana-Nogues et al, 1995;Gló ria et al, 1999;Brillantes and Samosorn, 2001) to produce fluorescent products or strong chromophores, but direct UV detection of histamine's imidazole ring has also been applied (Frattini and Lionetti, 1998;Shakila et al, 2001, Cinquina et al,2004b. Other popular separation-based methods include ion chromatography (Cinquina et al,2004a), capillary electrophoresis (Gallardo et al, 1997;Zhang and Sun, 2004), paper electrophoresis (Sato et al, 2002(Sato et al, , 2006, thin layer chromatography (Lieber and Taylor, 1978;Bajc and Gačnik, 2009) and gas chromatography-mass spectrometry (Marks and Anderson, 2006).…”
