odor threshold

Relationship between volatile organic compounds release, their molecular interaction, and sensory data.

This study explores the relationships of evaporation dynamics, metal oxide semiconductor (MOS) sensor analysis, sensory panel perception of essential oils, and molecular docking interactions of D-limonene, eugenol, citronellol, isoamyl acetate, and cis-3-hexen-1-ol. The VOCs showed strong correlations (Pearson r=0.96–0.98) between evaporation rate and odor intensity for D-limonene, isoamyl acetate, and cis-3-hexen-1-ol, whereas eugenol exhibited low correlations. Real-time MOS data validated these evaporation profiles.
