Determination and source tracing of toluene in spices and spice extracts: focus on thermal conversion of α-pinene to toluene during processing.

This study investigated the presence and origins of toluene in spices and their extracts. A headspace gas chromatography-mass spectrometry method quantified six benzene series compounds, with limits of detection of 0.10 mg/kg, limits of quantification of 0.30 mg/kg, and recoveries of 72.2-109.4% (RSD <10%). Toluene was...
