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 activity and/or odour:

    Criticism is infested with the cant of materialism, which assumes that manual skill and activity is the first merit of all men, and disparages such as say and do not, overlooking the fact, that some men, namely, poets, are natural sayers, sent into the world to the end of expression, and confounds them with those whose province is action, but who quit to imitate the sayers.
    Ralph Waldo Emerson (1803–1882)

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