A method using headspace-solid-phase microextraction-gas chromatography-mass spectrometry to extract volatile compounds from whiting is developed. Several parameters such as sorption time, desorption time, fiber type, and matrix form are optimized to achieve better sensitivity in minimal analysis time. The efficiency of the method is determined by the linear range and repeatability; a mean relative standard deviation of approximately 7% is measured. It was possible to identify and quantitate 30 volatile compounds of interest present in spoiled whiting.
