  2. Odor detection threshold - Wikipedia

    en.wikipedia.org/wiki/Odor_detection_threshold

    Odor threshold value (OTV) (also aroma threshold value (ATV), Flavor threshold) is defined as the most minimal concentration of a substance that can be detected by a human nose. Some substances can be detected when their concentration is only few milligrams per 1000 tonnes, which is less than a drop in an Olympic swimming pool. Odor threshold ...

  4. Odour activity value - Wikipedia

    en.wikipedia.org/wiki/Odour_activity_value

    Odour activity value (OAV) is a measure of importance of a specific compound to the odour of a sample (e.g. food). It is calculated as the ratio between the concentration of individual substance in a sample and the threshold concentration of this substance (odour threshold value, the minimal concentration that can be detected by human nose).

    en.wikipedia.org/wiki/Olfactometer

    An olfactometer is an instrument used to detect and measure odor dilution. Olfactometers are used in conjunction with human subjects in laboratory settings, most often in market research, to quantify and qualify human olfaction. [1] Olfactometers are used to gauge the odor detection threshold of substances. To measure intensity, olfactometers ...

  9. Key odorant - Wikipedia

    en.wikipedia.org/wiki/Key_odorant

    Key odorants can be identified by comparing the concentrations of the odorants with their respective flavor threshold. The resulting unit is the odor activity value (OAV). Every key odorant has an OAV higher than 1.
