In this study, the characteristics of panel members with various factors on the odor judgement using a air dilution olfactory method were investigated. The frequency distribution curves of Dev(D/Ttotal) and Dev(D/T₃) were found to be a normal distribution, but it appears that values around median on the distribution curve of Dev(D/T₃) were relatively sparse. Factors of outlier deviate from a confidence interval of 99% were found to be male ＜ female, smoker ＜ non-smoker, experience ＜ non-experience, and bad ＜ common state of health. Data obtained from female panel members appears high positive(+) deviation on the odor judgement.
