Abstract: Smokeless tobacco products (STPs) are widely used in certain parts of the world, yet there is limited understanding of how they are consumed, particularly the impact of chemosensory characteristics on their use. In order to develop an understanding of the drivers of STP use and product acceptability we conducted both human sensory panel testing and chem. analyses on a range of STPs. Free-sorting paired odor testing using sensory panellists identified similarities and clear differences between eleven different STPs. Headspace volatiles, analyzed by headspace solid-phase microextraction gas chromatog. mass spectrometry (HS-SPME-GC-MS), identified 20 to 70 components depending upon the STP. Key differences in headspace volatiles were found between STPs. For example, the headspace of Skoal Bandits Wintergreen was dominated by Me salicylate, while Marlboro Spice consists of a more complex profile including pinene, nicotine, eugenol and cymene. Chemometric Target Factor Anal. (TFA) and Hierarchical Cluster Anal. (HCA) of chem. and sensory data was used to deduce chem. drivers of sensory perceptions. The chemometric strategy used showed that headspace anal. is a complementary screening tool to sensory anal. in classification studies. This study is generic with applications across various product sectors that require routine human sensory panel evaluation.
