Validation by collaborative trial of a method for the determination by GC-MS and LC-MS/MS of boar taint marker compounds in pork tissue.


ABSTRACT: Meat from male pigs may develop an off-flavour, commonly known as boar taint. Castration of male piglets prevents the potential formation of off-flavour. In the suggested method, three marker compounds for boar taint (skatole, androstenone and indole) are quantified in pork fat by isotope dilution gas chromatography mass spectrometry (GC-MS) or by isotope dilution liquid chromatography tandem mass spectrometry (LC-MS/MS). This method was validated by collaborative trial according to ISO 5725-2:1994. The studied concentration ranges included sensorial thresholds. The repeatability relative standard deviation (RSDr) ranges from 3% to 10% and the reproducibility relative standard deviation (RSDR) from 10% to about 30%. The method has proven to be robust and free from matrix interferences. The method performance characteristics are compliant with requirements for official control methods in the area of food contaminants; therefore, the method is regarded as fit for its intended purpose.
