Olfactory perception of 5α-androst-16-en-3-one: Data obtained in the residents of central Russia

Abstract

This dataset describes olfactory perception of androstenone (5α-androst-16-en-3-one) in residents of central Russia (n=807, 9-84 years old). Based on previous studies, 3.13 × 10^-3% androstenone was utilized for sensory testing. A modified two-alternative choice task with "no-difference" options was applied as an odor discrimination procedure. The participants rated the perceived odor intensity and pleasantness on 3-point categorical scales. The subsequent task was free odor identification. We used a survey to determine characteristics of our study population such as age, sex, ethnicity, olfactory abilities, smoking habits, respiratory tract diseases, perfume use, blood group. To examine sex differences in characteristics of participants, as well as in their perception of androstenone, we have applied one-way ANOVA for age variable and Chi-square tests for categorical variables. The dataset will be useful for assessing the impact of the aforementioned factors on the perception of volatile steroids. A wide range of researchers studying verbal descriptors of specific odors and cross-cultural differences in olfactory perception may reuse this dataset. Primarily, this dataset may benefit meat industry, as androstenone, which is perceived as an unpleasant odor by about a quarter of the population, significantly contributes to pork flavor.
