Event: JSAE Spring Conference
Odor of a new car is caused by a complex mixture of various compounds evolved from interior parts and materials. To grasp the odor and the compounds responsible for the odor, sensory evaluation and instrumental gas analysis were carried out. In sensory evaluations, odor intensity, pleasantness and odor characters were evaluated for 73 new cars. The compounds of the odor of 17 new cars were analyzed with GC and GC-MS using adsorbent tubes and canisters.
From the principle components analysis of sensory evaluation results, odor characters were classified into six types. The correlation between sensory evaluation results and concentrations of odor compounds identified the compounds responsible for the odor.
