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).

Famous quotes containing the words odour and/or activity:

    Such fragrant flowers do give most odorous smell;
    But her sweet odour did them all excel.
    Edmund Spenser (1552?–1599)

    Labor is work that leaves no trace behind it when it is finished, or if it does, as in the case of the tilled field, this product of human activity requires still more labor, incessant, tireless labor, to maintain its identity as a “work” of man.
    Mary McCarthy (1912–1989)
