Optimisation of solid-phase microextraction coupled to gas chromatography for determination of phenolic compounds in smoked herring
2003
Serot, Thierry | Lafficher, Cecile
Solid-phase microextraction coupled to gas chromatography was evaluated for analysis of phenolic compounds in herring fillet samples, using a polyacrylate fibre (film thickness: 85 μm). An experimental design approach determined that time and temperature, the main parameters affecting the extraction process, were optimal at approximately 55 min and 50 °C. The effects of different amounts of fillet on percent recovery of phenolic compounds were then studied. Finally, the method developed was used to determine phenolic compound content in smoked herring fillets. The results showed good correlation (R2=0.96) with those obtained by simultaneous distillation extraction.
