Scope

This document specifies the headspace-solid phase microextraction/gas chromatography-mass spectrometry method for determining the five key volatile aroma components of Liubo tea, including linalool, menthol, geraniol, β-violet ketone, and cedrol. This document is applicable to the determination of the content of five key volatile aroma components in Liubo tea, including linalool, menthol, geraniol, β-violet ketone, and cedrol. When the sampling amount is 0.1 g and the volume of the sample solution is 10.0 mL, and the quantification is performed using the selected ion scanning mode, the detection limits of linalool, menthol, geraniol, β-violet ketone, and cedrol are 0.7 μg/kg, 0.5 μg/kg, 0.9 μg/kg, 0.2 μg/kg, and 0.5 μg/kg, respectively, and the determination limits are 2.8 μg/kg, 2.0 μg/kg, 3.6 μg/kg, 0.8 μg/kg, and 2.0 μg/kg, respectively.
