A study of odor reproduction using multi‐component olfactory display

A sensory test experiment (triangle difference test) was conducted using the 20‐component olfactory display to confirm odor reproduction based on odor components. The essential oils used were lemon, palmarosa, carrot seed, elemi, lavender, cypress and mentha arvensis. Each one was selected from seven essential oil categories. The sensory test reveals that it was difficult to distinguish between the reproduced odor and the target one. Thus, the odor reproduction by olfactory display based on odor components was generally possible. Furthermore, we found that the participants used its features or intensities as clues to distinguish between the blended odor and the target one from a survey of the free comments on the questionnaire sheets.
